What is Roof Waterproofing?
Waterproofing is a protective treatment that stops water from entering concrete and building surfaces through cracks, joints, and porous materials. By forming a strong moisture-resistant layer, it helps prevent leakage, seepage, damp walls, mould growth, and damage to structural components. Waterproofing is commonly applied to roofs, terraces, basements, bathrooms, foundations, balconies, and water-retaining structures to improve durability, reduce future repair costs, and increase the overall lifespan of a building.
What is Roof Heatproofing?
Heatproofing is a roof and surface protection system designed to minimise heat transfer into a building. It works by reflecting sunlight and reducing the amount of heat absorbed by exposed surfaces, helping maintain a more comfortable indoor temperature. Heatproofing is widely used for residential houses, commercial buildings, warehouses, factories, and offices to improve energy efficiency, reduce cooling expenses, and protect structures from continuous exposure to intense sunlight and changing weather conditions.

Types of Waterproofing & Heatproofing
Acrylic Waterproofing Coating
Liquid-applied flexible coating made from acrylic polymers. Forms a UV-resistant and elastic film. Ideal for exposed roofs, exterior walls, and terraces.
Cementitious Waterproofing
Uses cement-based compounds to create a rigid or semi-flexible protective layer that bonds tightly to concrete and masonry.
Bituminous Membrane Waterproofing
Asphalt-based sheets reinforced with polyester or fiberglass, forming a thick, seamless barrier.
Polyurethane (PU) Waterproofing
A liquid-applied membrane system that cures into a highly elastic, seamless layer. Excellent for surfaces with movement joints.
Crystalline Waterproofing
Penetrates deep into concrete to form insoluble crystals that block water pathways, providing lifelong structural protection.
Roof Waterproofing & Heatproofing
Prevent water leakage and reflects solar radiation to reduce surface temperatures and lower air conditioning costs.

Frequently Asked Questions
What is the difference between waterproofing and heatproofing floor coating?
Waterproofing floor coating prevents water leakage, moisture penetration, and dampness to protect concrete and structures. Heatproofing floor coating reduces heat absorption and surface temperature by reflecting sunlight and UV rays.
What is the best waterproofing chemical in Bangladesh?
The best waterproofing chemical depends on your application. For roofs, D-Seal A100 (acrylic) is ideal. For basements, D-Seal C200 (cementitious) works best. Furthermore, for flat roofs needing heat protection, D-Seal A200 (cool coat) is the top choice. Ducon manufactures all these products in Bangladesh.
How much does roof waterproofing cost in Bangladesh?
The roof waterproofing price in Bangladesh ranges from ৳35 to ৳80 per square foot. This includes both material supply and professional application. However, the final price depends on the roof area, current condition, and the system chosen. Get more details: +8801844652475
