There is continual concern over the potential for surface and groundwater contamination from nearby landfill operations . There is further concern about the ingress of too much precipitation and stormwater inflow into landfill sites with the attendant increase in the volumes of leachate generated. In the longer term, therefore, it is important that any liner systems employed as a cover barrier or cap, maintains its integrity over the operating period required of it.

In addition to the obvious construction activities which may compromise the integrity of any weak liner system, the other major concern is the ability of the system to accommodate the differential movements and settlements which are associated with consolidating waste bodies over time without losing their integrity and resistance either to upward migration of gases nor to the downward migration of precipitation.

In these situations, liner systems which have a proven resistance to the gases and condensates of organic wastes are required in addition to their having all the physical and mechanical properties which resist puncture and tearing both during and after construction and where excellent multiaxial properties are required.

Typically, Linings which fall into this category can be divided , but certainly not limited to the following groups: Landfill caps / silage covers / ash and cover protection / Hazardous and Harmful Waste segregation covers.
