Comparison of Pre-Applied HDPE Self Adhesive Waterproof Membrane and Traditional SBS Bitumen Membrane
The Advantages of High Polymer HDPE Self-Adhesive Membrane1.The basement floor adopts the pre-applied construction method, the polymer self adhesive HDPE membrane is completely bonded with the structure, eliminating the problem of water channeling;
2 It does not need any protective layer when it is used for the waterproofing of the basement bottom plate, which can save the project cost and construction period;
3.The HDPE waterproof membrane is not affected by the settlement of the base layer and remains integrated with the structure;
During construction, it will not be affected by the dampness of the base surface, and can lay on the basement surface directly ;
The installation process is fast and simple, with complete node processing prefabricated supporting systems ;
It is non-flammable, self-extinguishing away from the fire, and has good environmental performance;
7.The service life can reach more than 15~20 years.
Traditional Modified Bitumen Waterproofing Membrane SBS Features
SBS waterproof material needs a protective layer after construction;
There are hidden fire hazards during the construction process, and the construction process is cumbersome;
High requirements for the moisture content of the base layer, and hot-melt bonding is used for the overlap treatment;
Detailed nodes are not easy to be handled;
Easy to be affected by base displacement;
It is flammable and easy cause environmental pollution ;
7 . The service life is 3~5 years.
