Best Waterproofing in Bangladesh
Polyurethane waterproofing is one of the most advanced waterproofing systems for protecting concrete structures, rooftops, basements, balconies, water tanks, and exposed surfaces from water damage. In Bangladesh, where heavy rainfall, humidity, and water seepage are common, polyurethane waterproofing provides a long-lasting and flexible protection system against leakage and dampness.
At Fountech, we provide high-performance polyurethane waterproofing solutions designed for residential, commercial, and industrial structures across Bangladesh. Our PU waterproofing membrane creates a seamless, elastic, and highly durable waterproof layer that protects concrete from cracks, moisture penetration, and weather damage.
Polyurethane waterproofing is a liquid-applied waterproof coating that forms a seamless and flexible membrane over concrete and masonry surfaces. Once cured, the membrane becomes highly resistant to water, UV rays, chemicals, and temperature changes.
Compared to conventional waterproofing systems, polyurethane waterproofing offers superior crack-bridging ability and flexibility, making it ideal for structures exposed to movement, vibration, and harsh weather conditions. PU waterproofing is widely used for roof waterproofing, basement waterproofing, terrace waterproofing, bathroom waterproofing, and industrial waterproofing projects in Bangladesh.


- Aliphatic Polyurethane Waterproofing: The aliphatic acrylic polyurethane is a chemical compound is use as a coating in industrial as well as building applications. The chemical makeup of aliphatic acrylic polyurethane makes it strong as well as flexible, and it is additional to several goods to make a durable finish.
- Aromatic Polyurethane Waterproofing: The aromatic polyurethane membrane waterproofing coating is a free flow non-shrink coating precisely designed for use where high strength and high fluidity are essential. It’s expressed as a usual aggregate method with a shrinkage compensating binder and is very highly flowable except forgoing power or performance abilities.
