Torch the membrane of a minimal length of 3m; This may be increased by the extension of the foundation footing; At the head of the membrane, fix the membrane with four mechanical fixings per linear meter; Apply the membrane to the foundation footing’s rim over 0.10m at least or, under the level of the premises over 0.30m; Work from bottom to top; For heights greater than 3m, cover the mechanical fixings by the endlaps (15cm). The laps are staggered from each other; The maximal waterproofed height is limited to 15m.
