PROCESS FOR REDUCING WATER PERMEABILITY OF POROUS SOILS

PROCESS FOR REDUCING WATER PERMEABILITY OF POROUS SOILS

A method of treating porous soils to increase their water-holding capacity comprising applying an asphalt-in-water type emulsion having a median asphalt particle size of from about 0.4 to 1.0 microns to the surface of the soil to be treated. Preferably, the soil is prewet and the submicronic emulsio...

Zusammenfassung:A method of treating porous soils to increase their water-holding capacity comprising applying an asphalt-in-water type emulsion having a median asphalt particle size of from about 0.4 to 1.0 microns to the surface of the soil to be treated. Preferably, the soil is prewet and the submicronic emulsion is applied in a dilute form having from about 1 to about 20 percent solid residue.
