Liners: Preparation

GEOTAS will assist with the design, planning and installation of your project.

The surface to be lined must be smooth and free of excessive water, rocks, sharp stones, sticks, roots, sharp objects, vegetation and debris of any kind.

The surface should provide a firm, unyielding foundation for the membrane with no sudden, sharp or abrupt changes or break in the grade.

No sharp stones or other hard objects that will not pass through a 10mm screen should be present in the 25mm of the surface to be covered.

Liner rolls are generally deployed from a special trailer. Access to and around the site needs to accommodate the vehicle and trailer, with a profile that can also support a fully laden weight of around 2.5 tonnes.


The membrane is buried in an excavated anchor trench. Once the liner fabricated and testing is complete, the trenched liner is backfilledadand compactd to prevnt slippage or contraction.
