Factory workshop basic anti-leakage Separation, choose HDPE geomembrane, or SBS waterproof membrane?

According to the national environmental protection requirements, the basis for the preparation of the foundation waterproofing construction plan for the new workshop: After the foundation is compacted and rolled, a film isolation layer needs to be made on the upper part (it is recommended to use SBS waterproofing membrane or HDPE geomembrane. The leakage layer and the anti-corrosion ground structure is different according to the surface layer and the base layer. For construction on the ground, the ground structure of the plate-shaped block surface layer is used, which is generally composed of a surface layer, bonding layer, isolation layer, leveling layer, cushion, and The composition of the base soil layer; the squeezing method is easy to operate, and the ash joints are full and dense; for the parts with high requirements for anti-corrosion, heat resistance, and anti-seepage, such as drainage ditches, pits, and pickling rooms, isolation, and anti-seepage layer should be prepared. Reinforcement is then tied, and concrete is poured.

The new workshop foundation anti-leakage separation design specification requires HDPE geomembrane SBS waterproof roll, which one is more suitable?

Width comparison: The width of HDPE geomembrane is generally about 6 meters, which is convenient for laying and construction in large workshops; SBS waterproof membrane is 1-2 meters wide, which is too narrow and wastes a lot of lap joints. Too many lap joints can also cause leakage The reason is important.

Cost comparison: The general price of SBS waterproof membrane is about 10 dollars, while the price of HDPE geomembrane products with the same anti-seepage effect is about 5 dollars.

Through the comparison of the above two points, I believe that everyone has a comparison in their hearts, and it is the right way to choose the one that suits you.
