Wykamol CM8 Geotextile Membrane – External Waterproofing & Drainage (Pallet Rate)
The Wykamol CM8 Geotextile Membrane is a high-performance, heavy-duty cavity drainage membrane designed for superior water management and external waterproofing. Ideal for retaining walls, earth-covered structures, and basement waterproofing systems, it effectively protects against water ingress, reduces hydrostatic pressure buildup, and ensures long-term structural integrity. The membrane is available at pallet rate pricing for bulk purchases, offering substantial cost savings for large-scale projects.

Key Features & Benefits:
-
High-Strength HDPE Construction: Provides durability, impact resistance, and long-lasting performance in demanding environments.
-
8mm Stud Profile for Advanced Drainage: Efficiently channels water away from structures, preventing pressure buildup and ensuring reliable waterproofing.
-
Integrated Geotextile Filter Layer: Prevents soil particles from clogging the drainage system, allowing water to pass through without obstruction.
-
External Waterproofing Compatibility: Works seamlessly with Wykamol HydroTank 1K & 2K coatings and other waterproofing systems for enhanced protection.
-
Easy Installation & Flexibility: The lightweight membrane is easy to cut and conform to irregular surfaces, simplifying installation and ensuring a seamless application.
-
Multi-Purpose Use: Perfect for retaining walls, basement walls, green roofs, podium decks, and other below-ground structures.
-
UV-Stabilised & Thermal Insulation Benefits: Withstands environmental exposure, providing durable protection while enhancing insulation performance.
-
High Compressive Strength & Drainage Capacity: The membrane supports backfilling with excavated earth, without compromising drainage efficiency.
Application Process:
-
Surface Preparation: Ensure the surface is clean and dry. If applying over existing waterproofing systems, ensure they are fully cured before installing the membrane.
-
Membrane Installation: Roll out the membrane against the external structure, ensuring the geotextile side faces outward for optimal filtration.
-
Fixing the Membrane: Secure the membrane using Wykamol Brick Plugs or mechanical fixings, spaced 500mm apart. Overlap the sheets by 100mm to ensure a waterproof seal.
-
Drainage System Integration: Install a perimeter drainage system at the base of the wall to direct water to a sump, soakaway, or discharge point.
-
Backfilling: Backfill with clean, coarse gravel to enhance water movement and avoid sharp objects that could damage the membrane.
