Why Bangladesh Needs Advanced Waterproofing
With 57% of Bangladesh facing high flood risk and year-round humidity exceeding 80%, advanced waterproofing is not just a luxury—it’s a necessity. Among the many options available, the bituminous membrane waterproofing method has become the preferred choice, thanks to its durability and flexibility. Moreover, rising demand for self-adhesive bituminous membrane systems and the cost-effective 1.5mm bituminous membrane price in Bangladesh highlights the importance of understanding the latest bituminous membrane prices in Bangladesh. This knowledge empowers builders to make informed, budget-conscious decisions.
In this guide, we will explore every essential detail—from different membrane types to effective installation strategies—tailored specifically for Bangladesh’s unique climate and construction needs.
1. What is a Bituminous Membrane?
To start, a bituminous membrane is a petroleum-based waterproofing sheet made by combining bitumen with polymer modifiers such as SBS (Styrene-Butadiene-Styrene) or APP (Atactic Polypropylene). This combination creates a high-performance barrier suitable for various environments, including bathrooms and basements.
Key advantages include:
✅ Hydrophobicity: Actively repels water
✅ Flexibility: Accommodates surface movements without cracking
✅ UV Resistance: Withstands Bangladesh’s intense heat
2. Self-Adhesive Bituminous Membranes: Revolutionizing Installation
Unlike traditional torch-on systems, self-adhesive bituminous membranes feature a peel-and-stick backing. Therefore, they require no flame, solvent, or special tools, making them safer and easier to use. These membranes are particularly suitable for Bangladesh’s monsoon-prone regions and smaller-scale projects.
Why Bangladesh Benefits the Most:
✅ Fast application between rain breaks
✅ No fire hazards, leading to safer work sites
✅ Labor cost reduction by up to 30%
✅ Ideal for DIY enthusiasts and rural areas with limited skilled workers
These self-adhesive sheets simplify installation—just peel, align, and press firmly for immediate waterproofing.
| Type | Installation Method | Best For | Lifespan |
|---|---|---|---|
| Self-Adhesive | Peel-and-stick | Foundations, DIY | 20+ years |
| Torch-On | Heated with propane | Large commercial roofs | 15–20 years |
| Liquid-Applied | Brush/Roller | Uneven surfaces | 10–15 years |
3. 1.5mm Bituminous Membrane Price in Bangladesh: Balanced & Reliable
Among the different thickness options, the 1.5mm bituminous membrane offers the best balance between cost and durability. It is well-suited for:
✅ Residential sloped roofs and balconies
✅ Kitchens, bathrooms, and wet rooms
✅ Areas with moderate foot traffic
For instance, a 1m x 20m roll of 1.5mm bituminous membrane covers 20m² and weighs approximately 10–13kg.
Price Range:
Currently, the 1.5mm bituminous membrane price in Bangladesh ranges from ৳1,100 to ৳1,300 per square meter, making it a cost-effective yet high-quality option.
4. Bituminous Membrane Waterproofing Method: Step-by-Step
Next, let’s dive into the proper waterproofing method using bituminous membranes to ensure lasting protection.
Preparation:
- Clean the surface thoroughly to remove dust, oil, and debris
- Fill cracks larger than 1mm with epoxy filler
- Apply primer to enhance membrane adhesion
Installation Process:
- Carefully unroll the membrane without stretching it
- Peel back 30cm of the film backing at a time
- Press firmly using a roller to eliminate air bubbles
- Maintain overlaps of 10cm on the sides and 15cm at the ends
- Seal all edges with butyl tape or bitumen sealant
Additional Tips for Bangladesh:
- Install membranes at temperatures between 25–35°C, avoiding peak noon heat
- Use moisture-tolerant primers in humid zones
- Cover partially installed areas promptly during monsoon season to prevent water damage
By mastering these steps, you ensure maximum adhesion and long-lasting resistance, even under Bangladesh’s challenging climate conditions.
5. Updated Bituminous Membrane Price in Bangladesh (2024)
Here is a detailed price breakdown based on membrane thickness:
| Thickness | Price (BDT/sqm) | Common Uses |
|---|---|---|
| 1.5mm | ৳1,100 – ৳1,300 | Roofs, bathrooms |
| 2.0mm | ৳1,400 – ৳1,600 | Terraces, water tanks |
| 3.0mm+ | ৳1,800+ | Parking areas, bridges, basements |
