Waterproofing chemistry (1)

Waterproofing solutions are essential for protecting structures from water damage, leveraging advanced chemical formulations for long-term durability. Admixtures are added directly to concrete to enhance its internal water resistance, reducing internal permeability. Elastomeric coatings create a flexible, seamless barrier that adapts to structural movement while preventing moisture penetration.

Polyurea and polyurethane coatings offer rapid-curing, high-performance protection, making them ideal for harsh environments and heavy-duty applications. Waterproofing membranes—available in sheet or liquid-applied forms—form durable, impermeable layers that protect surfaces from water infiltration. Cementitious waterproofing chemically bonds with concrete to form a rigid, protective layer, making it ideal for basements and water-retaining structures.

Crystalline waterproofing penetrates deep into concrete, forming insoluble crystals that block water pathways and self-seal minor cracks over time. Each waterproofing chemistry serves a specific purpose, catering to diverse environmental challenges and construction requirements. These solutions extend structural lifespan, reduce maintenance costs, and improve overall durability.

An effective waterproofing strategy prevents leaks, mold growth, and structural degradation. Whether for new construction or renovation, advanced waterproofing technologies ensure resilience and sustainability. Choosing the right waterproofing chemistry enhances safety, efficiency, and long-term structural performance.

Polyurethane waterproofing is a durable and flexible solution that forms a seamless, elastomeric membrane to protect surfaces from water infiltration. It is ideal for a variety of applications, offering resistance to UV radiation, weathering, and temperature extremes.

Prefabricated waterproofing membranes are factory-engineered sheets, typically made of materials like HDPE, TPO, or bitumen, designed for superior water and damp proofing with consistent thickness and high tensile strength.

HDPE (High-Density Polyethylene) is a thermoplastic polymer known for its high strength-to-density ratio, chemical resistance, and durability. It is widely used in construction applications, including waterproofing membranes, due to its impermeability to water and excellent performance in harsh environments.

SBS (Styrene-Butadiene-Styrene) is a thermoplastic elastomer that combines the properties of rubber and plastic, offering excellent flexibility and elongation. It is widely used in modified bitumen membranes, enhancing their durability, crack resistance, and performance under extreme temperature variations.

PVC (Polyvinyl Chloride) membranes are durable, flexible synthetic waterproofing materials known for their excellent resistance to UV rays, chemicals, and weathering. These membranes are commonly used in roofing and waterproofing applications, offering long-lasting protection and easy installation.

Hydrofom 100, 200, and 201 are advanced polyurethane injection grouts designed to stop water leaks in concrete structures, with variations offering two-component or single-component formulations for different sealing and waterproofing applications.

Special waterproofing products under this category, such as PrimeShield, SilicoShield, Multiguard EP, and AquaBlock, are manufactured to deliver exceptional performance and protection to concrete.
