The bed drainage media normally consists approximately as follows: 1. The top layer is 5 cm of sand, usually with an effective size of 0.3 to 3 mm. 2. Three intermediate gravel layers, each 10 to 15 cm deep, having from the top to bottom an effective size of 4 to 8 mm, 16 to 32 mm, and 32 to 64 mm respectively. 3. Underdrain piping or perforated tiles should be of a material that does not fail when front end loaders are driven across the bed for solids residue removal. 1, record 1, English, - bed%20drainage%20media

La fondation est placée sur un lit de drainage granulaire qui se prolonge de 300mm au-delà des semelles. Le remblai poreux, qu'il s'agisse du sol excavé bien drainé ou de nouveau matériau, est amené jusqu'à 300mm (12 po) du niveau définitif du sol et la partie restante est remblayée au moyen d'un matériau moins perméable ou du sol excavé placé en pente pour faciliter le ruissellement. Le matériau de drainage poreux dirige l'eau de la nappe phréatique vers le sous-sol, prévenant ainsi la création d'une pression hydrostatique et les fuites d'eau consécutives dans les murs et dans les planchers du sous-sol. Un puisard, conforme aux exigences du code du bâtiment évacue l'eau par gravité ou par un moyen mécanique. 2, record 1, French, - lit%20de%20drainage
