PRODESO DRAIN 8 - Membrane

PRODESO DRAIN 8 is a draining, waterproofing and uncoupling membrane composed of a high-density polyethylene (HDPE) sheet, a non-woven draining polypropylene fabric and a polypropylene non-woven fabric. The cyan polyethylene sheet is 8 mm in height

and with truncated conical studs with a circular base on which a draining non-woven polypropylene white fabric is thermo-welded.

Below the membrane has a polypropylene non-woven fabric glued to the polyethylene. The non-woven fabric guarantees bonding to the support and is waterproofed

for 15 cm on one side using a polypropylene film. It extends by about 7.5 cm beyond the polyethylene sheet.

The product is a draining, waterproofing, uncoupling membrane, which guarantees the vapour management with a thickness of 8 mm. It does not require expansion

joints in the screed before the installation of ceramic and natural stones.

The product guarantees the installation of any flooring, waterproofing and drainage even on cracked and not perfectly cured substrates, therefore with possible vapour pressures and also in overlapping.

It neutralizes the differential movement that arise between the substrate and the flooring preventing breakage to the above floor; thanks to that, it

is possible to install tiles on cracked substrates and wood. Using the membrane, where movement joints are present in the subfloor, the membrane should be continuous across these junctions.

Using PROBAND KOLL AB, bi-component waterproof cementitious adhesive, on the waterproof tape of the product and along the perimeters, it is possible to achieve proper waterproofing. In addition, the water that penetrates under the flooring, is drained and removed so the efforescence and the migration of resins on the flooring

surface are drastically reduced.

The air volume between the draining fabric and polyethylene sheet, reduces drastically the curing of the adhesive used for the flooring installation and the efforesceces on the grout surface.

The cavities of the truncated conical reliefs of the membrane guarantee the vapour pressure management generated by the evaporation of residual moisture from

the support. It could also be applied on substrates that are not perfectly cured or able to absorb humidity such as wood.
