Lining & Containment
Impermeable barriers that last.
HDPE geomembrane lining
Geomembrane and clay-liner systems for water storage, waste containment and canals.
A lining system is a sequence of layers, and the membrane is one of them. The subgrade beneath, the cushion above it, the seams between sheets and the protective cover over it all decide whether the barrier holds.
We supply the sheet and the other layers, and our crews weld, test and record each seam.

Jump to the selection guideHDPE Geomembrane
High strength and chemical resistance; the standard for landfills, tailings and hazardous waste.
HDPE sheet is strong and resists a wide range of chemicals. Sheets are welded on site by hot-wedge or extrusion, and each seam is tested. HDPE is the usual liner for landfills, leachate ponds, tailings and process water. Thickness is chosen for the duty, the subgrade and the cover.
LDPE Geomembrane
More flexible and easier to handle, for ponds, canals, tanks and secondary containment.
LDPE sheet is more flexible than HDPE and follows uneven ground with fewer wrinkles. It is easier to handle and deploy. It suits ponds, canals, tanks and secondary containment where the chemical duty is moderate and the geometry is awkward.
Pond Liners
Reservoirs, retention basins, ornamental ponds and artificial streams.
Liners for water storage: farm ponds, reservoirs, retention basins, ornamental ponds and artificial streams. The liner is anchored in a trench at the crest and protected from sun and traffic. Edge details and side-slope angle are as important as the sheet.
GCL & Landfill Systems
Geosynthetic clay liners with drainage, protection and capping layers.
A geosynthetic clay liner is a layer of bentonite held between geotextiles. It seals by swelling when wet. In landfill base and capping systems it is combined with geomembrane, drainage and protection layers, so that each layer does one job. The layer order follows the regulatory design.
Typical lined section
Built in layers, top to bottom.
Seaming, protection layers and subgrade preparation matter as much as the sheet itself. Our crews weld, test and record every seam.
