ABSTRACT:
A process for constructing a self-sealing layer for landfills and waste dumps that use a base layer, cap layer, or liner to seal the area from water percolation through cracks or holes. A layer of soil is provided having specified characteristics which will become flowable under the effects of water moving through the layer. The soil is moved into the crack or hole by the water and accumulates until the breach is sealed. Geotextiles, otherwise known as textile mats, may be used inside the layer to reinforce the layer and enhance the self sealing effect of the flowable soil layer. Water glass and an appropriate gelling agent may be used in an embedding zone on either side of the mat to enhance the adhesion between the mat and the material in the cap, base, or liner.
