At present, the commonly used basement waterproofing structure includes the basement side wall, waterproof layer, insulation board and backfill soil laid from the inside to the outside; the existing waterproof layer mostly uses the self-adhesive membrane for basement side wall waterproofing used on the market to carry out basement side wall waterproofing construction. The surface of the self-adhesive membrane is easily damaged or slippery when backfilling the soil; for this reason, China Patent Authorization Announcement No.: CN216405502U discloses a basement side wall waterproofing structure, including a cross membrane waterproofing layer, an insulation layer, a self-adhesive layer, a waterproofing layer and a base layer.

After the polystyrene board is pasted to the HDPE outer protective layer, it can prevent knocking or scratching during the backfilling process. When a sharp object scratches the polystyrene board and contacts the HDPE outer protective layer, the HDPE outer protective layer is made of HDPE as raw material, and is manufactured by vacuum forming or mold stamping in a molten state to obtain an external protective layer with flexibility and supporting stiffness; it can resist the impact of sharp objects. The HDPE outer protective layer adopts a layered assembly structure of a mesh base layer and a cover layer. The mesh base layer serves as a holding cavity for TLS rubber asphalt grouting liquid, and the mesh base layer is integrally bonded to the HDPE self-adhesive waterproof membrane.

During construction, a layer of cement mortar is first scraped on the outside of the basement side wall, and after the cement mortar is solidified to form a cement mortar leveling layer, a base treatment agent is coated on the cement mortar leveling layer. After the base treatment agent is solidified, the base treatment layer is obtained.
