Column Point Waterproof Board – High Elongation, Non-Slip Function

A white column point waterproof board is on two black column point waterproof boards.

Walcoom provides column point waterproof board with good stability applied to construction with slope.

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.


  • Good impermeability performance.
  • Good stability, better non-slip function.
  • Wear resistance, acid and alkali resistance.
  • Corrosion resistance, anti-aging.
  • Weather resistance, low and high temperature resistance.
  • High elongation, high tensile strength.

    High-density polyethylene.
  • Thickness
    1.0–3.0 mm.
  • Width
    4–8 m.
  • Length
    We can customize according to your request.
  • Color
    White, black, green or as your request.
  • Friction coefficient
