WATERPROOF MESH MEMBRANE
Waterproof Mesh Membrane - HDPE cavity memebrane with 8mm studs
Waterproof Mesh Membrane
SkilledBuild’s Waterproof Mesh Membrane is a cavity drainage membrane manufactured from high density polyethylene (HDPE) used to isolate damp/wet walls above and below ground. The membrane has 8mm studs which create cavity drain membrane channels, behind which any free water can run. This product incorporates HDPE mesh lathing which allows direct application of mortars, lime renders, plaster or dot and dab plasterboard finishes.
The Waterproof Mesh Membrane is ideally suited to post flood damaged property or properties experiencing damp issues as it creates a barrier to damp yet maintains drainage and air circulation.
Our Waterproof Mesh Membrane is also available as part of our Waterproof Mesh Membrane Kit, which contains all the materials required to undertake 40m2 of waterproofing at your property.
Please see our Product Data Sheet for installation guidance.
Areas of Use:
- Waterproofing below ground level.
- Isolating damp walls above ground level.
This system was used extensively by specialist building contractors in post flood renovations after the 2007 UK floods to help speed up the process of reinstatements and to protect the affected properties from the ingress of damp from adjoining neighbouring houses. The fact that the Waterproof Mesh Membrane can be directly plastered saves time and does not affect any other trades or processes.
The Waterproof Mesh Membrane should be stored in dry conditions, avoiding sharp objects, direct sunlight and high temperatures.
- Waterproofing Rope.
- Waterproofing Corner Tape.
- Waterproofing Tape.
- Waterproof Membrane Plugs.
- Plaster Plug Seals.

Key Benefits of our Waterproof Mesh Membrane:
- Use to create dry and habitable living spaces in areas suffering from damp or wet conditions.
- Little or no damage to existing structure.
- Quick to install, little preparation required.
- Low and high temperature tolerance.
- Accepts direct plaster finish.
- Water, rot, salt, root and contaminant resistant.
- Easily malleable and cut with scissors for application around windows doors and services.
Where Waterproof Mesh Membrane is installed in basements it is essential that the Waterproof Mesh Membrane is used in conjunction with a suitable sump and pump facility, unless passive drainage is available. It is essential that the sump and pump facility is 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 Mesh 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.
Where there is a lack of natural ventilation it may be necessary to consider should also be given to providing an adequate means of condensation control.

How do I install Waterproof Mesh Membrane?
For a detailed guide to installing Waterproof Mesh 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 Skilled Build’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 Mesh Membrane.
Fixing the Membrane:
Hang the membrane down the wall and using drill, drill the centre of a stud in the centre of the membrane, to a depth greater than the fixing length. (The Waterproof Mesh Membrane can be fitted against the wall or floor horizontally or vertically.)
A fixing then needs to be pushed into the hole until it is flush in the stud.
The Waterproof Mesh Membrane should be fitted from the centre of the membrane outwards. Keep the membrane level and taught to avoid ripples.
Fixings should be no further than 250mm apart for each other to ensure as flat a surface as possible, avoiding rippling of the membrane and subsequent cracking of the applied finish. Particular attention should be paid to corners and revels to ensure the membrane is tight to the wall. It may be necessary to use more fixings in these areas.Where dry lining, fixing centres may be increased to 350mm. When using with external render applications, the fixing centre should be reduced to 150mm.
Subsequent sheets should overlap stud to stud, with the non-mesh studs interlocking. Seal the overlap with Waterproofing Rope.
Waterproofing Tape is perfect when you lace the tape between the flange of one sheet and the top surface of the next. If the flange is not flat to the stud joint then you should use our Waterproofing Rope which is ideal for that application.
Where the Waterproof Mesh Membrane is installed above the Damp Proof Course level, leave a 10mm gap at the top and a 20mm gap at the base of the wall in order to provide a ventilated system. It should be finished with off-set or ventilated cappings or skirtings.
All plasters and renders should be applied in accordance with manufacturer’s instructions and good plastering/rendering practice. (BS5492/BS5262).
Use proprietary lightweight plasters or a 6:1:1 render mix. Do not use soft or building sand. A two-coat application is recommended allowing 7-10 days between coats depending on site/weather conditions. Both plasters and renders must be to a minimum total depth of 15mm. The first coat should be applied with firm pressure to the depth of the studs and cover the mesh. The coat should be scratched to provide a sound key for the floating coat. Then finish with a 3mm skim coat.
For dry lining use a conventional bonding plaster in dabs to minimum thickness of 8mm and that cover at least 50% of the membrane surface area.
Once the plastered, dry-lined or rendered surface has dried, permanent decorations can be applied including vinyl wall papers and oil paints.
- To seal services in walls and floors, cut the Waterproof Mesh Membrane around them and seal using Waterproofing Rope and Waterproofing Corner Tape.
When Waterproof Mesh Membrane is installed in basements, it must be used in conjunction with a suitable sump and pump facility unless passive drainage is available.
Where there is a lack of natural ventilation, it may also be necessary to consider how condensation will be controlled.
The Waterproof Mesh Membrane has no specific hazard specification. However, general precautions should be taken in the use of the associated equipment such as drills, hammers etc. and working in confined spaces. The Waterproof Mesh Membrane should be stored in dry conditions, avoiding sharp objects, direct sunlight and high temperatures.
Waterproof Mesh Membrane delivery takes between 3 and 5 days.
