PEHD membrane sealing systems for landfill base liners - Waste and Recycling - Landfill

There are several phases of preparation of landfill base liners, starting with the positioning of the membrane, until these can be covered with several metres of refuse. These membranes may be damaged during preparation, but can also be inspected and repaired. It is advisable to undertake inspections at regular intervals.

Areas which are already covered and are many meters below the surface and which are therefore no longer readily accessible for repair should nevertheless be inspected if there is any concrete reason to suspect that their integrity could have been impaired, for example as a result of fire.
