Civil Materials — Building Stronger Foundations & Structures

Welcome to the civil engineering and structural solutions hub at THS Now. The integrity of any building depends not just on its design, but on the chemical and material science embedded within its foundations. Whether you are reinforcing a new concrete slab, managing site-wide waterproofing, or executing critical structural repairs, the materials you choose dictate the lifespan of the asset. THS Now provides a specialized selection of professional-grade civil supplies—ranging from high-performance admixtures to advanced waterproofing membranes—engineered to protect structures against the elements and mechanical stress.

Technical Factors in Civil Supplies

In civil construction, "standard" is often not enough. To ensure a structure remains resilient against moisture, chemical ingress, and load-bearing fatigue, engineers and contractors must look toward specialized chemical interventions.

Enhancing concrete strength with additives

Modern concrete is a high-tech composite. By integrating specific concrete admixtures, you can drastically alter its performance characteristics. Plasticizers and superplasticizers allow for high-slump, easy-to-pour concrete without the need for excessive water, which can weaken the final cure. Accelerators speed up setting times for urgent repairs, while air-entraining agents improve durability in environments prone to thermal expansion and contraction.

Preventing structural damage via waterproofing

Water is the single greatest threat to structural longevity. Once moisture reaches the steel reinforcement (rebar) within concrete, it triggers oxidation (rusting), which causes the metal to expand and the concrete to "spall" or crack. Effective waterproofing isn't just about surface coating; it involves creating an impermeable barrier at every vulnerable point—from the basement foundation to the terrace slab—to ensure the skeletal integrity of the building remains dry and protected.

Selecting the right repair mortar for cracks

Not all cracks are created equal. Hairline shrinkage cracks often require a flexible filler to accommodate minor movement, while structural cracks demand a non-shrink repair mortar. Unlike standard cement, these specialized mortars are engineered to bond aggressively to existing concrete and maintain their volume as they cure, ensuring that the repair becomes a permanent, load-sharing part of the original structure rather than a temporary patch.

Explore our Civil Engineering Range

To help you find the exact chemical or material solution for your project, the THS Now civil catalog is organized into specialized categories focused on structural health and protection.

Waterproofing Compounds

Protect your property from the foundation up. Our collection features crystalline waterproofing for basements, liquid-applied bituminous membranes for retaining walls, and high-performance acrylic or PU-based coatings for terraces and balconies. These compounds provide a seamless, elastic shield against water ingress and dampness.

Concrete Admixtures

Optimize your mix design for superior performance. THS Now offers a range of integral waterproofing liquids, strength-enhancing plasticizers, and corrosion inhibitors. These additives are essential for creating high-density, low-permeability concrete that meets modern engineering specifications.

Grout & Crack Fillers

Achieve precision in structural bonding and finishing. Our range includes non-shrink epoxy and cementitious grouts for machine foundations and column base plates, as well as specialized crack injection resins and flexible wall putties designed to restore the aesthetic and structural continuity of your surfaces.

Curing & Protection Chemicals

Ensure your concrete reaches its full design strength. We provide high-efficiency curing compounds that form a moisture-retaining film over fresh concrete, eliminating the need for constant ponding. Additionally, explore our surface hardeners and dust-proof coatings designed to protect industrial floors from heavy wear and chemical spills.

Buy Professional-Grade Civil Construction Materials Online

Sourcing technical civil supplies across local markets often leads to inconsistencies in batch quality and a lack of technical documentation. THS Now eliminates these risks by providing a transparent, factory-direct supply chain. We maintain extensive inventories of trade-certified construction chemicals and repair materials under one digital storefront. Every product in the THS Now collection adheres to stringent IS (Indian Standards) and international quality benchmarks, allowing civil engineers and private contractors to fulfill their Bill of Materials (BOM) with absolute confidence in the chemistry they are deploying.

Frequently Asked Questions

Which chemical is best for roof waterproofing?

For most residential and commercial terraces in India, a UV-resistant, liquid-applied elastomeric coating (like those from the Dr. Fixit Newcoat or Heat Shield ranges) is highly effective. These coatings form a seamless, rubber-like membrane that can bridge minor cracks and withstand the extreme thermal expansion and contraction common on flat roofs.

What is the difference between grout and standard cement?

While both are cement-based, grout is a specialized mixture designed to flow into gaps and provide a non-shrink, high-strength bond. Unlike standard cement, which can shrink as it loses moisture—leaving micro-gaps—specialized grout maintains its volume or expands slightly during curing to ensure 100% contact between surfaces, making it ideal for tiling, machinery mounting, and structural repairs.

Are these materials suitable for both new construction and repairs?

Yes, absolutely. The civil materials available at THS Now are divided into two primary use cases: structural additives and waterproofing for new construction to prevent future issues, and repair mortars and injection resins designed specifically to rehabilitate existing structures that have suffered from cracking, dampness, or carbonation. Always check the specific product description for its intended application.
