Column point waterproof board
Column point waterproof board is a kind of special waterproof board. It is made of high-density polyethylene. Just like general waterproof board, column point waterproof board also has great impermeability performance. So it is widely used in road, highway and many underground constructions. The column joint is for non-slip. Compared with rough surface waterproof board, the column point waterproof board has higher friction coefficient and better non-slip function. So it can be used in the construction with steep slope to prevent infiltration and stabilize the foundations.
