1 - Spreading of a coat of Primer on the bottom, by the hole.
2 - Spreading of a thin membrane piece, 50x50 cm., make it adhere to the bottom after heating it by torch. If, on the contrary, the waterproof mantle is composed of more layers, the drain shall be
laid after the first layer and the piece is suppressed.
3 - Try the drain in the hole and make sure that it has a grade of 3°.
