Protecto-Drain PL8

Protecto-Drain PL8 2017-12-20T02:22:44+00:00
Protecto-drain PL8 is installed vertically as a protection and dam proof layer in internal walls and subterranean structures. It is designed to securely hold up rendering and plastering

Protecto-drain can be manufactured with a polyester mesh bonded to one side. Plaster and rendering can be laid onto the membrane and adheres to the surface, allowing internal walls to be constructed.

Tile adhesive can also be installed onto the mesh.

This material is very useful for internal tanking and basement rooms where the HDPE membrane acts as a waterproofing and damp-proofing layer, and the internal plaster can then be installed on top. Protectodrain plaster grade material is ideal for retro-fitting of rooms in basements and underground installations.

As well as the regular HDPE / mesh version, a membrane incorporating the HDPE membrane, the polyester mesh bonded one side and a geotextile fabric bonded the other side. This geotextile gives a protection and cushioning layer to prevent any risk of the waterproofing or delicate membrane immediately behind the Protecto-drain becoming damaged.

A range of white fixing studs and edging strips specifically for the plaster grade membrane is available.
