DWI Bituminous Insulation Rolls — Waterproofing and Leak-Proof for Concrete Surface Protection

DWI bituminous insulation rolls — waterproof and leak-proof for protecting concrete surfaces

DWI bituminous waterproofing membranes offer a practical and reliable solution for protecting concrete surfaces from water and moisture penetration. These membranes are designed to form a durable and flexible barrier that resists weathering and extends the lifespan of structures while reducing the need for frequent maintenance.

Key advantages

• A strong and effective barrier against water and moisture.
• Flexibility that allows it to withstand thermal shrinkage and expansion without cracking.
• Resistant to corrosion and tearing under normal operating conditions.
• Suitable for flat and uneven concrete surfaces after proper preparation.
• Available in sizes and thicknesses to suit the requirements of different projects.
• Long-term performance reduces maintenance and repair costs.

Common uses

• Insulating concrete roofs (building and house roofs).
• Protecting foundations and basements against groundwater seepage and moisture.
• Insulation of swimming pools and artificial ponds.
• Covering bridges and concrete structures that require an effective water barrier.
• Civil construction and urban renewal projects.

General installation guidelines

1. Surface preparation: removing dirt, oils and loose materials, leveling cracks and filling gaps.
2. Apply a suitable primer if required to ensure better adhesion.
3. Spread the rolls out, leaving a suitable overlap between the rows (according to product specifications).
4. Glue or heat-weld the edges according to the product's recommended method.
5. Examine sensitive points (edges, openings, passages) and treat them with special angles and reinforcements.
6. Conduct a leak test after installation to ensure the barrier is intact.

Safety tips

• Follow the manufacturer's instructions regarding installation methods and support materials.
• Use personal protective equipment when handling welding tools or adhesives.
• Avoid prolonged exposure to chemical vapors without adequate ventilation.
