Troubled by frequent water leakage & seepage?

We have long-term & economical waterproofing solutions

For a construction to sustain a longer life, every small things which damage the structure should be taken care of. One of the most critical and most neglected of these is waterproofing of the structure.

The lack of knowledge regarding this leads to leakages and seepages in the structure due to unintentional cracks created on the structure surface causing entry of unwanted water in the structure and damaging its construction. If not taken the initial signs seriously, these cracks and water seepage can lead to major cracks and structural damages in future and can even lead to structure failure.

Water damage also leads to decay and deterioration of the structure. To stop this entry of unwanted water in the structure is done with the process of waterproofing. In this process the water loving nature of the surface is transformed to water repelling nature and will result in no unwanted water entry.

Most waterproofing chemical solutions provided in the market are like a structural film on the surface and do not form a chemical bond with structure. With time the surface is exposed to different temperatures, climatic conditions and wearing which leads to peeling of the film or even cracking of the film leading to new crack formation on the surface and exposing the surface unwanted water entering situation. These waterproofing chemicals do not provide complete waterproofing rather only provide temporary solution via film formation done using physical adhesion.

To solve this problem and provide a long term solution for waterproofing helping to maintain the health and looks of the structure, Zydex industries provide a penetrative nanotechnology solution which forms a chemical bond with the surface. This solution penetrates the existing cracks and treats them to make them water repelling in nature. The solution is 100% silane and reacts with the structure surface and forms a chemical bond which does not get effected by temperature, climate change and wear. This solution also prevents involuntary cracking of the surface and make the whole surface hydrophobic i.e. water repelling in nature.

This also solves the other problems like leakages, seepages, paint peel-off, falling of tiles and stones from the surface, efflorescence and further structural damage. It also provide UV, Heat and Abrasion stability and safe to apply indoors. The application is very simple and do not require trained labour. The solution can be sprayed, brushed or flooded after mixing with water and has a large coverage area. The waterproofing chemical solution provided by Zydex is not only for the exterior surface but also for interior surface and also replace the fragile membrane technology with a waterproofing membrane technology. The product can be used on Terrace, Slabs, Basements, Sunkens, Retaining walls, Balconies, Water tanks, Utilities etc. The waterproofing chemical bonding solution provided is a nanotechnology solution:

• With excellent penetrative results,
• Is economical in use,

Microsurfacing Asphalt Manufacturer

Microsurfacing is a thin layer of finely graded crushed stone, mineral fillers, asphalt emulsion and water blended together in proper proportions, spread on the road surface. It is very similar to slurry seal.

Micro-surfacing helps seal the cracks and protects the existing bituminous layers from surface voids & minor ruts, and provides a protective cover from oxidation and moisture ingress. Micro-surfacing is also provided in order to improve skid resistance of the existing surface thus increasing the service life of the pavement. A small amount of additive may be added at times, to improve the setting properties and adhesion of the micro-surfacing.

Microsurfacing is distinct from slurry seals. It hardens much quicker and can be applied in places where there are zero or minimal chances of placing slurry seals. Micro-surfacing can be ideally used on roads that handle substantial vehicular movement. It preserves the underlying pavement structure, while providing a fresh new surface for driving.

Factors for considering Micro-surfacing application

  1. Micro-surfacing can be applied on roads that have low or moderate damage and narrow width of cracks.
  2. Streets with lot of shade are preferred for micro-surfacing
  3. Roads with heavy amount of traffic are suitable for micro-surfacing
  4. It is typically applied on a project-specific basis

Some of the major advantages of Micro-surfacing include:

Environment-friendly: Micro-surfacing is an environment friendly alternative as it requires relatively low energy, emits no pollutants and is applied at ambient temperatures.

Quicker Construction Times: The surface can be opened within hours of micro-surfacing and it gives the appearance of an all-new surface.

Reduced Delays: Micro-surfacing can be performed on roads with high, medium or low traffic volume, without causing any major delays.

Cost Effective: Micro-surfacing covers more area per tonne of mix, thus making it a cost-effective alternative.

NanoTac offers excellent bond strength & delivers water resistant mixes for micro surfacing. These additives impart rapid setting to the bitumen emulsion, saving the time required for micro surfacing.

Water Soluble Fertilizers

Water Soluble Fertilizers, Hard soils and declining productivity is and will be the biggest challenge faced by farmers in the years to come. We all understand that the uncontrolled used of chemical inputs and unsustainable farm practices is the main culprit; however, the solution is far from clear and understood.

Bio-fertilizers have been around for many decades now, but the technology hasn’t been able to single-handedly replace these harmful chemical inputs. Moreover, the abundance of fake products in the market has left farmers hopeless and apprehensive to try anything new. As a result, farmers feel that there is no option but to apply these inputs in large quantities in order to sustain their yields and livelihoods.

Zytonic-M is a new generation biofertilizer technology, which has the ability to break this toxic cycle. What makes it unique in comparison to others is that it can directly cut 50% of the chemical fertilizer input from the first use, whilst delivering higher yields and quality produce. Apart from establishing mycorrhizal connections with the crop, this water soluble fertilizer helps to improve soil structure and softness, which increases soil water holding capacity as well as aeration.

This, in turn, allows the local soil biology to proliferate and actively provide a constant source of (previously unavailable) nutrients to the plant, which are already present in the soil. A constant and adequate supply of water and nutrients throughout the growing season is the key to any successful crop. This is exactly what Zytonic-M, a water-soluble fertilizer, is able to efficiently achieve by utilizing the systems already put in place by Mother Nature. “Back to the basics” and allowing natural processes to take over is the key!

Zytonic-M Benefits:

• Increased yield (15-50%)
• High produce quality
• Reduction in irrigation (20-30%) and drought resistance
• Reduction in chemical fertilizers (50-100%)
• Reduction in pesticide consumption (20-40%)

The Basics of Textile Sizing – Explained!

What is Sizing?

Production of ‘quality’ fabric economically and efficiently is key aim of any textile company.Sizing is an intermediate protective process which is done to prepare the yarn for the weaving process. The process of applying a protective adhesive (synthetic/ natural) coating upon the yarns surface is called sizing. This adhesive can be single shot sizing chemical or a blend of multiple chemicals to achieve desired properties.

Advantages of Warp Yarn Sizing in Weaving:

Below are the key advantages of warp yarn sizing prior to weaving.

  1. To bind the yarn by adhering the fibers together and hence improve yarn strength.
  2. To cover outer yarn surface for improving abrasion resistance of the warp yarn.
  3. To lubricate the yarn surface for reducing friction during weaving process by preventing inter yarn entanglement and surface abrasion. This reduction of friction helps to keep the yarn intact and hence better fabric quality.

Sizing Process in nutshell:

  1. Yarn Sizing is carried out by passing the warp yarn sheet through size box containing the pre-prepared sizing chemical. The warp sheet is passed through tension roller, immersion roller, sizing roller and squeezing roller respectively in sow box. This is followed by subjecting the yarn sheet to drying cylinders heated through steam where the water is evaporated from yarn surface and sizing chemical forms a film on same.
  1. Next the yarn sheet is passed over the after waxing roller to coat the sizing chemical film with extra lubricants for hairiness control and ease of weaving.
  1. After drying and after waxing, the warp sheet is split so that the yarns regain their individual identity before they are wound on the weaver’s beam.
  1. Splitting is required because warp sheet coming out of the drying section adhere to each other depending on the efficiency of the pre-drying section. Chromium coated Lease rods split the warp sheet in a systematic manner so that the yarns which are stuck together by dried size are separated.
  1. After the splitting, the warp sheet is finally wound on the weaver’s beam. The warp sheet passes through an adjustable reed which can be expanded or collapsed based on the width of the beam.

Zydex had been pioneer in field of textile sizing. We have a wide range of products for sizing of spun yarn as well as filament yarns.

Zydex had been at the forefront of innovation for polyester sizing products. Today, Zydex has the leadership position in hot water dispersible polyester resin technology for sizing and weaving of polyester multi filament yarn on high speed weaving machines.

Soil Stabilisation Techniques

The role of soil is crucial for the design and construction of any structure, be it roads, runways or railway tracks. This is because it acts as the medium for effective load transfer in to the earth. This implies that a weak soil base will eventually cause settlement of the structure, leading to failure.
Stabilisation is the process of improving the engineering properties of the soil before construction. Stabilisation is done to improve the strength of the soil and shrink/arrest the swelling potential, thus improving the load bearing capacity and the overall performance of the in-situ soils.

There are 3 main methods for soil stabilisation:
1. Mechanical stabilisation

This category consists of physical processes such as compacting or tamping with machineries including rollers or rammers. The mechanical soil stabilisation is also achieved by blending (adding or removing) different soil particles so as to obtain effective distribution of soil particle. These techniques are usually used for sub-base and base courses.

2. Chemical Stabilisation

As the name suggests, stabilisation of soils depends on the chemical reaction between the chemical/stabiliser used and the soil particle composition. These include, Cement, Lime, Magnesium Chloride, Bitumen Emulsion and Fly Ash among others.

Traditionally and widely practiced type of soil stabilisation techniques include:

i. Bitumen Emulsion
Bitumen emulsion is used as a binding agent both cohesive as well as non-cohesive soils. However, in soils with finer grain sizes, this method may no longer be cost effective as the soil particles require a high dosage of bitumen emulsion in order to provide the same/better level of bonding. Bitumen emulsion is not environmentally friendly and becomes brittle when it dries, which affects the stability of the soil.

ii. Cement/Lime
Cement/Lime is widely used as a soil stabilising agent. Addition of cement to soil improves the strength of the soil. It is used for the sub-base and base courses of all types of pavement. However, due to the consequent wet and dry cycles, there occurs a degradation of the bonding between the cement and soil particles. Also, this is a very costly in terms of financial viability. Lime stabilisation improves the strength of the soil by imparting increased bonding between the lime and soil particles. This method is cost effective as compared to cement stabilisation.

iii. Apart from the above mentioned stabilising agents, some other alternatives currently in practice include Fly Ash, Cement Kiln Dust (CKD), Tree Resin and Ionic Stabilizers.

3. Polymer Stabilisation

Polymer soil stabilization refers to the addition of polymers to improve the physical & engineering properties of soils (Polymer Soil Stabilisation, 2019).
Polymers tend to increase the strength of the soil through their interaction with clayey particles present in the soil. Many polymers currently used, tend to increase the water retention capability and the shear strength of the soil.
Polymers used for soil stabilisation can be classified into two main categories viz. Biopolymers and Synthetic Polymers. Biopolymers are eco-friendly as compared to other chemical soil stabilisers.

Soil Conditioner Fertilizer Manufacturer

Soil Conditioner – Synthetic fertilizers are rampantly used in conventional farming. They initially resulted in high yields but over the last few decades, it has lead to a decline in soil health and stagnation in yield quantity & quality.

To counter this problem, a combination of both biofertilizers and soil conditioners is the optimum solution.  The soil conditioner component works as a soil amendment that improves soil porosity and water holding capacity, leading to a larger and active root zone and promotes the growth of beneficial biology.

The bio-fertilizer component adds mycorrhiza (beneficial fungus) as an inoculum to further boost its population leading to an extension of the existing root zone, which enables higher water and nutrient absorption. Mycorrhiza is a beneficial fungus that provides essential nutrients in exchange of sugar exudates from the plant. The glomalin secreted by it provides a better structure to soil & stimulates the growth of soil biology such as beneficial nematodes, protozoa and bacteria that help recycle nutrients between the crop and soil.

This combination of bio-fertilizer and soil conditioner along with the use of organic inputs such as FYM, Vermicompost, etc. allows a minimum 50% reduction of chemical fertilizers in the first use with subsequent reduction of up to 100% with continuous usage over 3-4 seasons. The idea is to revive the soil biology and bring its population & activity to an optimum level along with provision of bio-feed in the form of FYM, vermicompost etc., thus reducing the dependence on chemical fertilizers over time.

Zytonic-M: A sustainable product for a bountiful harvest

Zytonic-M is an excellent combination of a bio-fertilizer and soil conditioner that activates & enhances the population of the soil biology.It develops healthy soils, thereby reducing the need for harmful chemicals and water.

  1. For high plant survival in drought conditions + water savings
    Zytonic-M makes soil soft & porous thus improving it’s water holding capacity. It also builds a substantially larger & denser root zone, which allows the crop to draw water from a much larger surface area. This leads to an extension of the watering cycle and higher plant survival during drought conditions.
  1. For higher soil biomass and improving soil organic content (SOC)
    Zytonic-M promotes the growth of a larger root zone and exponential growth of the soil’s biological population, which contributes to higher biomass being recycled back in the soil. Moreover, the recommended use of FYM, vermicompost, etc. with Zytonic-M and incorporation of crop residues back into the soil further adds to the Soil Organic Content.
  2. For improved yields and higher immunity to pests & diseases
    Zytonic-M builds a highly populated and active soil biology, which constantly provides a ready source of plant available nutrients throughout the growing season. This helps to improve yields from the first use itself, whilst reducing the dependence on chemical fertilizers over time. It also leads to the growth of strong and high quality crops that are more resilient to pest and disease attacks, thereby reducing the need for harmful pesticides.

End Benefits of Zytonic-M as a soil conditioner/ soil amendment and bio-fertilizer for crops 

  1. Increased yield by 15% to 50%
  2. High quality in terms of size, nutrional content & shelf life
  3. Reduction in irrigation by 20% to 30%
  4. Reduction in chemical fertilizers by 50% to 100%
  5. Reduction in pesticide consumption by 20% to 40%

Zydex Agriculture Solutions enable crops to receive optimum quantities of nutrients by boosting the natural soil biology & allowing the soil ecosystem to proliferate. Zytonic-M improves drought resistance & nutritional uptake for a bountiful and high-quality harvest.

Bitumen emulsion for soil stabilization

What is stabilization?

Stabilisation is the process of improving the engineering properties of the soil before construction. Stabilisation is done to improve the CBR of the soil to be used for a specific construction purpose. This can be done using various additives including Portland cement, fly ash, lime, bitumen etc. These chemicals impart higher bond strength by providing cohesion between the soil particles.

Bitumen emulsion for Soil Stabilization

Using bitumen emulsion for soil stabilisation refers to the process of adding a specified amount of bitumen emulsion to the soil and mixing it appropriately to create a strong and stable base. The bitumen is dispersed in the water in the form of small droplets which are suspended in water by an electrostatic charge of the emulsifier.

Bitumen Emulsions can be used for stabilising both cohesive as well as non-cohesive soils. However, in soils with finer grain sizes, this method may no longer be cost effective as the soil particles require a high dosage of bitumen emulsion in order to provide the same/better level of bonding. Succinctly, the quantity of the bitumen emulsion will depend on the type of the soil so as to offer the desired strength to the soil base.

Following are some of the benefits attributed to the bitumen emulsion being used for soil stabilisation:

Waterproofing: Using bitumen emulsion for stabilisation is slightly different from cement stabilisation, as the soil particles coated with the emulsion renders it water-resistance.

Load bearing capacity: Soil stabilisation using bitumen emulsions result into a permanent sealing of the soil structure. This increases the load carrying capacity of the soil layers. The load distribution is 2-3 times higher than that of the unbound foundation layers.

Flexibility: The soil layers of the roads should act as supporting layers by absorbing the stresses of the vehicles moving on top of it and not deform under these stresses. In order to facilitate this, the soil layers need to be somewhat flexible, so as to retain the shape and size. In case of a rigid structural layer, the risks of crack formation are much higher thus increasing the risk of failure. This is the situation which calls for the use of bitumen emulsion. They are very thin flowing and can be easily mixed with the soil, which also calls for lesser bituminous binder.

Soil stabilisation with Foamed Bitumen

Additionally, foamed bitumen is also currently being used in the industry for soil stabilisation. Foamed Bitumen is a mixture of air, water and bitumen. Bitumen is heated on site and when small quantity of water is injected in to the hot bitumen, it expands explosively to about fifteen times its original volume and forms a mist or a foam. This results in to the formation of bitumen droplets with increased surface area. It has been proven that by applying foamed bitumen, it is possible to produce a semi-rigid layer of stabilised soil.

Safeguard your structures with nanotechnology based waterproofing solutions

Most construction materials used today in enormous quantities are not recyclable. The availability & quality of raw materials have posed serious questions for reliability in construction. The speed at which these resources are being depleted demands serious attention towards finding ways and techniques to mitigate this threat by implementing innovative solutions that can keep structures healthy and long -lasting.

Understanding Nanotechnology

If you ask about nanotechnology 90 out of 100 people will say “I have no idea”, and the other ten will give you varying explanations.

In the metric system of measurement, “Nano” equals a billionth and therefore a nanometer is one-billionth of a meter. Just to appreciate the size, a human hair is over 1,00,000 nanometers long; therefore, it is virtually outside the nanoscale range!

Waterproofing your structure for complete protection

Water seepage, “architect’s and home owner’s nightmare”, is a perennial problem that causes aesthetic and structural damage to a structure. Many waterproofing chemicals & techniques have been tried and none has an absolute success record.

Waterproofing approach in most cases is – ‘COVER-IT-UP’. We cover up the concrete with various available materials. In most cases, the COVER deteriorates (cracking, de-bonding, peeling, etc.) resulting in water ingress into the structure. This results in shortening of the useful service life of the structure.

Conventional waterproofing membranes like film formers form only a surface film over surface cracks. They cannot penetrate the micro cracks and pore channels and suffer from the following limitation: –

  1. Short life 2 – 5 years
  2. Thermal / UV degradation

New generation penetrative organosilane technology

Now – for the first time, a nanotechnology based waterproofing agent, indigenously developed for the Indian conditions – is available.

The New Generation Organosilane is a blessed technological breakthrough that has addressed almost all issues that prevented widespread use of the Silane technology for mass consumption. The salient features of this new formulation are:

  • Long Useful Service Life (UV stability upto 20 years)
  • Water Soluble – 20 times its volume (cutting transportation cost)
  • Easy to Apply (colloquially speaking, is Idiot-proofed, eliminating misapplication)
  • Eco-friendly (Meets the toughest Californian VOC norms)
  • Affordable (Can be even considered for Low-cost Mass housing)

Through penetrative nanotechnology the basic nature of the structure is changed from hydrophilic to hydrophobic. The earlier, water absorbing structure substrate, becomes water resistant.  This prevents water ingress in the structure and retards ageing of the structure.

The result is, significant life extension of the structures and optimize resource preservation.

Advantages of eco-friendly pigment printing process

Pigments are generally colored, organic or inorganic solid powder. They are insoluble coloring matter mostly mineral origin which are used for the coloration of metal wood, stone, and textile material. These pigments does not have any affinity with fibers. They are used with the binder system for printing.The binder ensures that pigment particles remain on fibre by forming a film on the fabric surface. Long macromocules of binder together with binder and thickener forms a 3-dimensional links on heat fixation. In the fixation process, the printed fabrics are treated with heat cure at 150 °C. This can be done in heat press or hot mangle, or in industrial process, in curing oven. The heat activates the binder to adhere the pigments onto the surface of the cloth. Unlike dye applications, fabrics printed with pigments do not require washing after fixations.

Advantages:

  • Easily applicable
  • Less expensive
  • Highly efficient because of the elimination of washing-off and other finishing processes
  • No pollution

Zydex presents a complete range of fabric printing solutions by offering a variety of innovative products in entire value chain processes right from grey selection to finishing. Our wide range of textile pigment printing inks allow customers to achieve reactive-like feel and color fastness without the effluent management hassles associated with reactive/ procion printing. This helps our customers to achieve higher production efficiency at minimum cost.

Eco friendly printing solutions for reactive and discharge replacement

Reactive/ Procion printing has been the mainstay of printing fabrics due to depth, brilliancy, soft feel and good crock and washing fastness. However reactive dyes require alkaline fixation, consuming large quantities of water for washing. Due to lack of 100% fixation dye contaminated water is produced. The final color depth and tone cannot be ascertained until the fabric is fully processed. This can be termed as blind printing which results into rejection due to color matching issues.

EPRICON

Epricon package is based on eco-friendly pigment systems with matching depth, solidity, soft feel and excellent crock and washing fastness. There is no effluent stream generated unlike reactive dying. Zydex uses pvc free inks and enables printers to move towards eliminating discharge printing processes without compromising on print quality and feel. Our rotary grade whites and clear inks are designed for highest opacity, hand feel and washing fastness mimicking discharge printing thereby eliminating water washing step.

WHAT ARE THE ADVANTAGES?

  • Replacement of Procion/ Discharge will eliminate pollution
  • It will lead to higher productivity due to removal of multiple pre and post printing processes
  • Being a direct printing technique it will reduce rejections

Is waterproof concrete effective in safeguarding the foundation of structures?

Concrete is highly prone to water pressure, either high or low. Few years after construction, it starts eroding and gradually exposes the base material & matrix laid. Simple concrete structures show these signs early and even come to the point of partial collapse.  More than 80% of issues in a structure are concerned with moisture intrusion, results in huge renovation costs.

Overcoming water ingress in concrete with Waterproofing

Water ingress results from water seepage in the structural defects like voids, honeycombs. If the structure stands on a water table or a near a high soil moisture area; concrete faces the threat of an early degradation.

Waterproof concrete prevents water ingress thus extending longevity to the structure. Use of sustainable waterproofing membranes during construction, can protect the structure by sealing pores.

A durable concrete foundation – Waterproofing makes the structure resistant to extreme water pressures by providing hard-wearing protection that is difficult to penetrate.

Replenish concrete gaps – Shrinkage cracks & structure defects that leave space for water ingress, are replenished, resulting in effective concrete bonding, leading to prolongs structure life.

A SUSTAINABLE SOLUTION FOR EFFECTIVE CONCRETE BONDING- COLD BOND

PCC (Plain Cement Concrete) or RCC (Reinforced Cement Concrete) are cast in parts, leading to formation of cold joints.

Joints between the old and the newly cast part become a weak link due to migration of water from newly cast concrete to the cured side.

Cold joints experience shrinkage stresses resulting in cracking & de bonding, leading to water ingress.
ColdBond is a unique formulation of Acrylic reactive nanotechnology. It exhibits dual properties of reactive Organosilane and acrylic copolymer viz.
(1) Penetration & Reaction which makes the concrete surface water resistant.

(2) Penetrative property ensures Water Resistance

(3) Strong Chemical bonding & sealing prevents de-bonding

ColdBond absorb shrinkage stresses, sustain thermal cycling & produces a water resistant bonding interface.

Concrete bonding with Cold Bond is a sustainable way to create monolithic joints, eliminating seepage & leakage and ensuring a firm foundation for the structure.
