It is required to be resistant to water pressure and blister, and there shall be no bulging, blistering and falling off, otherwise the waterproof layer will fail again.
The construction from the upstream surface, backfill excavation, construction and re backfilling have large quantities and long construction period; For construction from the back water surface, the requirements for waterproof materials are very high.
▲ Yuguo light repair ▲ Shengyang rubber and plastic ▲ Sichuan Tongshen ▲ Yixiu Tianxia basement interlayer reconstruction waterproof layer construction method the basement is generally low, surrounded by backfill, the water in the soil is constantly eroding inward, and the water pressure is large.
Sometimes the coating on the back surface can not be completely solved, so grouting is needed to rebuild the waterproof layer.
When leakage occurs in the basement roof, the maintenance is even greater.
When there are weak links in the basement waterproof layer, the water will take advantage of it.
