COLUMN POINT Rectangular Tear Strength 125-249N for Long-Lasting Performance
Product Overview
New anti-seepage material, divided into single and double rough
surfaces, with anti-skid function, generally used on slopes of
anti-seepage projects to improve the stability of the anti-seepage
system.
Applications
Summarize:Used in landfill anti-seepage, tailings ponds,
reservoirs, closures and other projects.
1. Anti-seepage in landfills, sewage or waste residue treatment.
2. River embankments, lake dams, tailings dams, sewage dams and
reservoir areas, channels, and reservoirs (pits, mines).
3. Anti-seepage lining of subways, basements, tunnels and tunnels.
4. Salt anti-seepage of roadbed and other foundations.
5. Horizontal anti-seepage covering in front of embankments and
dams, vertical anti-seepage layer of foundation, construction
cofferdam and waste yard.
6. Seawater and freshwater farms.
7. The waterproof layer of foundations of roads, highways,
railways, expansive soil and collapsible loess.
