In cities like Karachi, where extreme weather conditions—from scorching heat to heavy rains—can take a toll on buildings, roof waterproofing is no longer optional. One of the most trusted and effective methods is cementitious waterproofing.
Whether you’re dealing with minor seepage or major roof leaks, cementitious waterproofing offers a reliable and long-term solution. Here’s why it’s one of the best choices for protecting your roof.
Cementitious waterproofing is a two-component system that includes:
Liquid polymer (resin or acrylic base)
Cement-based powder
When mixed, they form a flexible, water-resistant coating that bonds with concrete surfaces to prevent water ingress. It is commonly used for roofs, water tanks, basements, bathrooms, and terraces.
The cement-polymer mixture fills micro-cracks and pores on the surface, forming a seamless waterproof barrier. It protects against:
Rainwater
Dampness
Seepage and moisture buildup
Once applied, cementitious coating becomes a part of the roof structure. It is UV-resistant, weatherproof, and heat-resistant, making it ideal for outdoor applications in Pakistan’s harsh climate.
It can be applied using a brush, roller, or spray. It adheres directly to RCC slabs, tiles, and cement-based surfaces—no complex machinery required.
Compared to other membrane systems, cementitious waterproofing is affordable and offers long-term value. It helps reduce maintenance costs caused by frequent leak repairs.
The elasticity of the polymer allows the coating to handle minor structural movements or expansion due to temperature changes—without cracking.
