This heavy-duty column-point geomembrane features cylindrical column points and is engineered to provide superior waterproofing and drainage capabilities for underground sewage storage facilities. Constructed from reinforced HDPE material, it delivers exceptional compressive strength to withstand soil pressure and sewage weight, while the innovative column-point design creates essential drainage gaps for groundwater, preventing membrane bulging and structural damage.
Ideal for lining residential septic tanks, commercial sewage pits, and rural decentralized sewage treatment facilities. This geomembrane effectively prevents sewage leakage, safeguarding groundwater and soil from contamination. The column-point configuration enables efficient drainage of surrounding groundwater, eliminating potential damage caused by hydrostatic pressure. Engineered to resist corrosion from sewage and septic tank chemicals, ensuring long-term durability and performance.
