NEEDFL water stop sheet
NEEDFL water stop sheet
NEEDFL water-stop sheet is a water-stop sheet for civil engineering construction work such as ports and reservoirs.It has excellent flexibility and can be heat fused, making it easy to install.
Features
- Because it has excellent elasticity and flexibility, it adapts well to the irregularities of the construction base, and because of its high mechanical strength, it exhibits a stable water-stopping effect even when buried in earth and sand or concrete.
- It has excellent aging resistance, weather resistance, and chemical resistance, and does not corrode even in seawater or sewage containing acids and alkalis.It also has excellent abrasion resistance, so it can withstand long-term use.
- Since it is made of soft vinyl chloride, it does not absorb or permeate water, making it suitable as a waterproof material.
- Can be integrated by heat fusion
Uses
- Water stoppage at general waste/industrial waste landfill sites
- Water stoppage of turbid water settling ponds and construction waste liquid treatment ponds
- Water stoppage of agricultural reservoirs and residential land development regulation ponds
- Water stoppage of breakwaters, sand control structures, detached shore structures, and reclaimed seawalls
