Backfill and foundation 人氣: 57 回覆: 0


Try to avoid backfilling the soil on the side of the high quality Galvalume Corrugated Roofing Sheet. When backfilling, the surface of the steel sheet and the backfill soil should be separated by a separator.

Ideally, a layer of the fixed pad is added to the high-quality Galvalume Corrugated Roofing Sheet on the concrete foundation, and the side of the galvanized steel plate is prevented from coming into direct contact with the pad. The fixed pad should be inclined at an angle to avoid water accumulation and to avoid draining to the edge of the galvanized steel plate.
