SureProof Waterproofing Membrane

SureProof is a high performance, cold applied, flexible waterproof membrane incorporating a cross-laminated HDPE carrier film with a strong adhesive polymer modified bitumen compound. The adhesive surface is protected by a disposable paper interleaving, wider than the membrane for easy release during application. To ensure correct sealing at overlaps there is a double-sided adhesive strip along the edges covered by a seperate interleaving strip.

SureProof should be laid according with the provisions of BS 8102:2009. Where SureProof is used as a floor DPM there should be continuity with the wall DPC's and other DPM's used in the structure. If methane presence is suspected, a comprehensive site survey should be carried out and Wykamol's technical department contacted to advise on the suitability of SureProof.


All surfaces must be clean, dry and free from contamination, ice and frost. Masonry surfaces must be flush pointed and all concrete surfaces must be a wood float or shutter finish and free from cavities or projections. All suface shall be primed with SurePrime. Floow application instructions on SurePrime technical datasheet, ensure complete coverage and allow to dry. Very porous surfaces may require more than one coat of primer to ensure the area is primed. SureProof can be applied in the same day.
