Key application areas
1. Environmental protection projects
· Landfill: used for bottom anti-seepage layer and capping to prevent leachate from polluting groundwater.
· Sewage treatment plant: anti-seepage isolation of regulating tanks and hazardous waste treatment sites.
2. Water conservancy projects
· Anti-seepage reinforcement of reservoirs, dams, and channels to reduce water resource loss.
· Waterproof padding of artificial lakes and reservoirs.
3. Agriculture and breeding
· Lining of fish ponds and shrimp ponds to prevent leakage and resist microbial erosion.
· Anti-seepage treatment of irrigation systems and biogas tanks.
4. Municipal and mining
· Waterproofing of subway tunnels and basements, anti-seepage isolation of tailings ponds.
· Anti-corrosion lining of chemical oil storage tanks and reaction pools.
Construction Technical Requirements
1. Base surface treatment
· It should be flat and free of sharp objects, with a compaction degree of ≥95% and a smooth transition of slope.
2. Welding process
· The joints should be clean and dry, avoiding moisture and dust; the welder should be preheated when the temperature is below 5°C.
· It is recommended to use hot melt welding, and the weld strength should reach more than 90% of the parent material.
3. Laying specifications
· Extend from low to high, leaving 1.5% expansion margin to accommodate settlement.
· Adjacent longitudinal joints should be staggered by more than 1m to avoid corner areas.
