Waterproofing chemistry (1)

Waterproofing solutions vary based on application areas, including basements and water tanks (cementitious waterproofing), roofs and facades (elastomeric and polyurea coatings), wet areas like bathrooms (liquid-applied membranes), and heavy-duty industrial zones (polyurethane and polyurea systems). Selecting the right waterproofing method ensures durability, moisture protection, and long-term structural integrity.

Waterproofing Products based on Application Areas

Basement Raft

Basement raft waterproofing involves applying high-performance membranes, crystalline coatings, or polyurea/polyurethane systems to prevent water ingress and structural deterioration. These solutions ensure long-term durability by creating a seamless, moisture-resistant barrier.

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.
