Why Choose the Toughsheet Black DPM Membrane?  

Durable & Sustainable
Made from premium recycled polyethylene, the Toughsheet DPM offers excellent resistance to tears and punctures while maintaining flexibility for easy installation

Reliable Moisture Protection

With its 100m2 coverage, this 4mtr x 25mtr DPM is suitable for residential, commercial, and industrial buildings, reducing the risk of damp-related damage.

Suited for Sustainable Drainage Systems (SuDS)

DPMs are commonly used with stormwater attenuation tanks, providing additional protection in water management and sustainable drainage solutions.

Key Features:

• 300MU Microns (1200 gauge) thickness for superior moisture resistance
• Large 4m x 25m coverage for efficient application
• Manufactured from high-quality recycled polyethylene
• Complies with BBA and PIFA standards
• Ideal for construction, flooring, and foundation damp-proofing
• Supports SuDS and stormwater management systems

Easy Installation for Lasting Protection 

Simply roll out the Toughsheet Black DPM over the required area before laying concrete or flooring materials. Ensure there are no punctures or tears to maintain its moisture-resistant properties.

Works Seamlessly with DPC

Overlapping the DPM with a damp proof course (DPC) creates a continuous moisture barrier, preventing rising damp and enhancing long-term protection.

The Risks of Skipping DPM Installation

Without a proper DPM, structures may face issues such as:

• Mould and mildew growth
• Damp patches and staining
• Timber decay and structural weakening
• Damage to plaster, wallpaper and interior finishes
• Reduced energy efficient and increased heating costs
