Abstract

Soil is consolidated by spraying with the components of a polyurethane foam to cause at least partial polymsn. of the components on contacting the soil. Esp. for consolidating loose ground or soil contg. soluble salts e.g. on sloping areas, underground works, roadsides, and preventing erosion caused by rain or rivers. Specif., the mixed components have a viscosity of >=10 cps. and comprise a diisocyanate, hydroxy cpd. and a foaming agent.
