Application of Composite Waterproofing System of Back-stick Polymer Film Reinforced Self-adhesive Membrane and Polymer Modified Bitumen Self-Adhesive Membrane in Structural Bottom Plate
The basement floor of Kunming Chuncheng Huafu project adopts a composite waterproofing system of 1.2 mm thick BSP back-stick polymer film reinforced self-adhesive waterproofing membrane and 1.5 mm thick carrierless polymer modified bitumen self-adhesive waterproofing membrane.This article focuses on the construction technology and detail treatment methods of the system.The application results show that the composite system with two waterproofing membranes bonded to each other has good waterproofing effect and can effectively solve the problem of water channeling between the membrane layers.
