Best Concrete Waterproofing solutions in Bangladesh​
Water is the single biggest threat to concrete structures in Bangladesh. With over 2,000mm of annual rainfall, high humidity, and seasonal flooding, unprotected roofs, basements, and water tanks develop leaks, cracks, and corrosion within a few years — often costing far more to repair than to prevent.
Fountech has been a concrete waterproofing company in Bangladesh since 2006,
We provide waterproofing solutions for concrete roofs, basements, foundations, water tanks, swimming pools, bathrooms, balconies, terraces, industrial buildings and other water-exposed structures.
Whether you are constructing a new building or repairing an existing concrete structure, our technical team can assess the site and recommend a suitable waterproofing system based on the substrate, water exposure, movement, environmental conditions and project requirements.

Professional Concrete Waterproofing Services in Bangladesh
Concrete is strong and durable, but it is not naturally waterproof. Water can enter through pores, cracks, construction joints, penetrations and poorly protected surfaces. Over time, moisture can contribute to dampness, coating failure, concrete deterioration and corrosion of embedded reinforcement.
Fountech provides complete waterproofing solutions designed to control water penetration and protect concrete structures for the long term.
Our waterproofing service can include:
- Site inspection and assessment
- Identification of water leakage and seepage sources
- Surface preparation
- Crack and joint treatment
- Selection of suitable waterproofing system
- Professional material application
- Detailing around vulnerable areas
- Final inspection and testing where applicable
- Technical support and maintenance recommendations
The right waterproofing system depends on the structure and site conditions. We therefore do not recommend the same product or method for every project.

Acrylic waterproofing coatings can provide flexible surface protection for exposed concrete roofs, terraces and other areas where UV and weather exposure are important considerations.

Cementitious waterproofing is a cement-based waterproofing system suitable for many concrete and masonry applications, including basements, bathrooms, water tanks, swimming pools and other wet areas

Polyurethane waterproofing creates a seamless and flexible membrane. Depending on the formulation and application, PU systems can be suitable for roofs, terraces and other areas where flexibility and crack-bridging performance are required.

Modified bituminous membranes provide a durable waterproof barrier and are commonly used for foundations, basements, roofs and other structures where sheet membrane waterproofing is appropriate.

Torch-applied membranes 3mm offer excellent waterproofing performance for flat roofs and industrial structures. Furthermore, they resist harsh weather conditions and extend roof life significantly.

Torch-on bituminous waterproofing 3mm is a waterproof membrane sheet made from modified bitumen with a thickness of 3 millimeters. It is installed by heating the underside with a gas torch so the membrane melts and bonds firmly to the concrete or roof surface.

Waterproofing Cost in Bangladesh
Waterproofing costs in Bangladesh typically range from à§³45–90 per square foot, depending on the system (acrylic, cementitious, polyurethane, or bituminous), surface condition, and number of coats required. Basic cementitious systems sit at the lower end; polyurethane and torch-applied bituminous membranes for high-exposure areas cost more due to material and labour intensity.

Common Concrete Waterproofing Problems We Solve
Waterproofing problems can have different causes. Applying another coating over an existing leak without identifying the source may only provide a temporary solution.
Fountech can assess problems such as:
- Concrete roof leakage
- Rainwater penetration
- Basement water seepage
- Damp concrete walls
- Water tank leakage
- Bathroom leakage
- Balcony and terrace leakage
- Cracks allowing water penetration
- Leakage around construction joints
- Failure of previous waterproofing systems
- Moisture-related concrete deterioration
Our approach focuses on identifying the cause of water penetration before selecting the waterproofing system.

Waterproofing Solutions
Stop leaks before they start. We provide best roof waterproofing and heatproofing system with ultimate protection and durability for your infrastructure with best waterproofing chemical in Bangladesh.

Key Features
- Strong Water Resistance: Creates a protective barrier that stops water leaks, seepage, and dampness.
- Excellent Adhesion: Provides strong bonding with concrete, masonry, and plaster surfaces for long-lasting waterproof protection.
- Crack Bridging Ability: Helps seal minor surface cracks and prevents water from penetrating through damaged areas.
- Weather & UV Resistance: Withstands harsh sunlight, heavy rainfall, humidity, and changing weather conditions without losing performance.
- Long-Term Durability: Offers lasting protection that extends the lifespan of concrete structures.

Benefits
- Block Water Leakage: Waterproofing protects roofs, basements, walls, and concrete surfaces from water seepage, leakage, and dampness.
- Increases Building Durability: It stops cracks and water damage, which extends the structural lifespan.

Our Concrete Waterproofing Process
Our Concrete Waterproofing Process
Site Inspection
We inspect the affected area and identify visible leakage, dampness, cracks, joints, drainage problems and other potential sources of water penetration.
Surface Assessment
The concrete surface is assessed for its condition, previous coatings, contamination, cracks, weak areas and other factors that may affect waterproofing performance.
Surface Preparation
Proper surface preparation is essential for good adhesion and long-term performance. Loose materials, contaminants and failed coatings are removed as required.
Crack & Joint Treatment
Cracks, construction joints, movement joints and penetrations are treated according to the selected waterproofing system and site requirements.
Waterproofing System Selection
We select the appropriate waterproofing technology based on factors such as water exposure, substrate condition, movement, UV exposure, service environment and project requirements.
Professional Application
The selected waterproofing system is applied according to the required application method, coverage and thickness.
Inspection & Testing
The completed waterproofing work is inspected and, where applicable, appropriate testing is carried out before the area is handed over.
Technical Support
Fountech provides technical guidance on the completed system and recommended maintenance requirements.
Right Waterproofing Solutions
There is no single waterproofing method that is best for every concrete structure.For example:
| Application | Possible Waterproofing Systems |
|---|---|
| Concrete roof | Acrylic, PU, cementitious or membrane systems |
| Basement | Cementitious, PU, bituminous or other suitable systems |
| Foundation | Bituminous membrane and other below-ground systems |
| Water tank | Cementitious, crystalline or other suitable water-retaining systems |
| Swimming pool | Cementitious, PU or other suitable systems |
| Bathroom | Cementitious or suitable liquid membrane systems |
| Balcony | PU, acrylic or other suitable membrane systems |
| Industrial roof | PU, acrylic or membrane systems |
The final selection should be based on actual site conditions rather than simply choosing the lowest-cost material.
