Damp Proof Membrane (DPM) – Waterproof Building Protection

Protect your building from ground moisture with our heavy-duty damp proof membrane. This essential waterproof barrier prevents rising damp, moisture penetration, and water damage in floors, foundations, and walls, ensuring dry, healthy buildings across Nigeria.

Key Features

• Waterproof Barrier: Impermeable polyethylene film blocks 100% of ground moisture and water vapor
• Heavy-Duty Construction: Thick, puncture-resistant material withstands construction site conditions
• Chemical Resistant: Unaffected by soil chemicals, alkalis, and ground contaminants
• Flexible Material: Conforms to uneven surfaces and wraps around obstacles easily
• UV Stabilized: Can be exposed to sunlight during construction without degradation
• Long Lifespan: Maintains waterproof integrity for the lifetime of the building
• Easy Installation: Lightweight rolls unroll and overlap easily for quick installation

Essential Applications

• Under Floor Slabs: Prevents ground moisture rising through concrete floors
• Foundation Protection: Waterproofs foundation walls and footings
• Basement Tanking: Creates waterproof barrier in below-ground spaces
• Wall DPC: Horizontal barrier in walls prevents rising damp
• Under Screeds: Protects floor screeds from moisture damage
• Radon Barrier: Prevents radon gas penetration in applicable areas

Technical Specifications

Material: High-density polyethylene (HDPE), thickness: 300-1200 gauge (0.075mm-0.3mm) depending on application, roll width: 2m, 3m, 4m standard widths, roll length: 25m, 50m per roll, color: Black or clear options available.

Installation Guidelines

Lay on compacted hardcore or sand blinding, overlap joints by minimum 150mm, seal overlaps with DPM tape, turn up at walls minimum 150mm above finished floor level, protect from punctures during concrete pouring.

Building Code Compliance

Meets Nigerian building regulations for damp proofing. Essential for habitable buildings to prevent moisture-related problems including mold, structural damage, and health issues.

Coverage Calculation

Measure floor area, add 10% for overlaps and wall turn-ups. For walls, measure height and length plus overlaps.
