WATERPROOF FLOOR MEMBRANE
Waterproof Floor Membrane 20mm Cavity Drain Channels for waterproofing basement and cellar floors
Waterproof Floor Membrane
SkilledBuild’s Waterproof Floor Membrane is a high performance cavity drainage membrane manufactured from high density polyethylene (HDPE) used to waterproof basement and cellar floors. The Waterproof Floor Membrane comes in rolls of 2.0m x 20m (40m2).
The Waterproof Floor Membrane is suited to properties where there are damp/wet basement/cellar floors, the quality and integrity of the existing floor slab is in question or where it is possible that water may pass through cracks in a poorly constructed floor.
How does it work?
The Waterproof Floor Membrane has 20mm studs that provide an air gap (drain cavity) between the membrane and the wall/floor, which allows any free water to run behind it. This product provides a high cavity drain capacity.
The Waterproof Floor Membrane can be rolled out, studs to the floor, and cut to fit the room. No mechanical fixings are required. Joints, and wall/floor junctions should be sealed with Waterproofing Tape or Waterproofing Corner Tape.
Installation results in little or no damage to the existing structure.
Please see our Product Data Sheet for installation guidance.
Areas of Use:

The Waterproof Floor Membrane should be stored in dry conditions, avoiding sharp objects, direct sunlight and high temperatures.

Key Benefits of our Waterproof Floor Membrane:
Damp proofing floor solution for both domestic and commercial projects
Little or no damage to existing structure.
When used as a floor membrane, insulation, under floor heating, screed (50mm) and floating floors can all be accommodated.
Internal walls can be built directly off the Waterproof Floor Membrane.
Water, rot, salt, root and contaminant resistant.
Where Waterproof Floor Membrane is installed in basements it must be used in conjunction with a suitable sump and pump facility, unless passive drainage is available. The sump and pump facility must be maintained throughout the lifetime of the membrane installation.
Tanking and cellar conversion works must always be in accordance with the relevant Building Regulations or British Standards. SkilledBuild’s Waterproofing Floor Membrane is suitable for use in accordance with BS8102:2009 to provide ‘Type C’ drained protection to structures below ground level, providing a Grade 3 or 4 dry environment suitable for domestic or commercial use.

How do I install Waterproof Floor Membrane?
For a detailed guide to installing Waterproof Floor Membrane, visit our Product Data Sheet.
Contaminated or loose plaster need to be removed and replaced.
Treat existing moulds or fungi with an appropriate biocide, such as SkilledBuild’s Mould Steriliser and Killer.
The floor must be cleared oil and any loose material.
Edges and large depressions must be levelled out.
Decide on a drainage design and test it before laying the Waterproof Floor Membrane.
Installing the Membrane:
The Waterproof Floor Membrane can be rolled out, studs to the floor, and cut to fit the room.
The flanged edge (strip of membrane running along the edge with no studs) should overlap the previous width of the membrane.
No mechanical fixings are required.
At wall/floor junctions the membrane can be cut flush and the gap sealed with Waterproofing Corner Tape. Where no wall membrane is being fitted, the floor membrane can be returned up the wall and cut flush with the top of the finished floor.
When Waterproof Floor Membrane is installed in basements, it must be used in conjunction with a suitable sump and pump facility unless passive drainage is available.
