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

Unlike base liners, surface liners are not buried at some point under many metres of waste and instead are usually protected over the course of many years only by a 1-metre thick mineral layer. As a result, there can be uncertainty about the integrity of their leak-proofing characteristics, particularly if the land is subsequently used for other purposes; however, at the same time, repairs are also possible at reasonable cost if the location of any damage can be established.
