Tight Peel&Stick

Viking Peel & Stick Membrane – is a self adhesive sheet membrane manufactured by Carlile USA, consisting of rubberised asphalt laminated to polyethylene. The membrane is 1.5 mm thick and supplied in rolls 0.914 m wide x 20.4 m long. horizontal tanking applications. It is primarily adhered to the outside of a sub-structure of a building (such as a foundation or basement) to prevent water ingress.

This Project
Primer, Peel & Stick membrane, 300mm wide reinforcing strip, aluminium fastening bar with sealant, 30mm polystyrene protection.
Tight access to the external wall, therefore the first 3 layers of blocks were laid and the mortar allowed to cure, so that the peel&stick membrane could be applied by leaning over the block wall. Retrieval of the polythene underfloor DPM was carried out before the next section of wall was laid.
To ensure the existing bank which had been cut back to build this commercial premises did not collapse the builder had to build a timber post and rail retaining wall.
This will remain in place even after the waterproofed concrete block retaining wall is backfilled to ground level.
The perforated drainage pipe is already been set in place under the gravel in the photos.
