Waterproofing Chemical – Description
A waterproofing chemical is a specially formulated substance used to prevent water penetration or leakage in building structures, materials, or surfaces. These chemicals form a barrier that either repels water or blocks it from passing through porous surfaces, thus enhancing the durability and life span of the structure.
General Description:
Purpose: To protect surfaces such as roofs, basements, walls, foundations, and water tanks from water damage, seepage, mold growth, and corrosion.
Form: Available in various forms such as liquid, powder, or membrane sheets.
Application Methods: Brush, roller, spray, injection, or mixing with concrete.
Base Types:
Acrylic-based
Polyurethane-based
Bitumen-based
Cementitious
Silicone/Silane-based
Epoxy-based
Key Properties:
Water resistance or repellency
Flexibility (to accommodate structural movement)
UV resistance (for external applications)
Chemical resistance
Crack-bridging ability
Breathability (in some formulations, to allow trapped moisture to escape)
Common Uses:
Roof and terrace coatings
Basement and foundation damp-proofing
Bathroom and kitchen wet area sealing
Concrete structure protection (bridg
es, tunnels, dams)
Water tanks and swimming pools
