surface sealing systems

Many factors determine whether a system for the surface sealing of a landfill body will be necessary. Besides the kind of deposited waste, the  individual site specifications as well as the country-specific legal stipulations assume dominant roles. For the gas generation process, a complete avoidance of water intake is a rather negative factor, but this way, a pollution of the ground water duct can be effectively prevented. As a „compromise solution“ systems can be planned and realised which allow a reduced water intake of the landfill body. The biologic conversion processes can continue on an adjusted level while at the same time the water drain to the aquifer is limited. The selection of a customised or „optimised“ sealing system requires special knowledge of the sealing technology and the individual location.
