Replacement and backfill soil disturbance, compaction watering should be layered or compacted thickness of each ≯400mm. 2, remove the exposed surface of the base material has a puncture hazards, such as brick, stone, tile; glass and metal debris; branches, roots and other plants. Cleanup floor there is an obstacle, to provide the necessary conditions for the laying of construction. 3, peripheral retaining wall, pump pit, foundation, and underwater nozzle installation and set aside work, farming membrane manufacturers must, before the end of construction of composite geomembrane. Geomembrane and retaining walls paste process. The adhesive is painted on the geomembrane and retaining wall with adhesive surface, drying stand for about 5 minutes, then paste, squeeze, Dover. Adhesive mix asphalt emulsion paints, cement, water from. Paste is completed, the water level above the solder nail anchor, and waterproof, anti-corrosion treatment.
