The present invention relates to the use of a composition for stabilizing a geological formation in oil fields, gas fields, water pumping fields, mining or tunnel constructions. The composition has a hardening temperature in the range from about 40 C. to about 120 C. and can therefore be used to stabilize a geological formation in oil fields, gas fields, water pumping fields as well as in mining or tunnel constructions.

A process for regulating the water retention of soil materials used in agriculture involving providing a composition comprising a polymer selected from the group consisting of a urethane, a urethaneurea, a thiocarbamate and mixtures thereof, said polymer comprising hydrophobic and hydrophilic segments; and applying the composition onto soil materials used in agriculture to form a polymer film thereon, wherein the hydrophobic and hydrophilic segments together provide reversible hydrophobic-hydrophilic switching in response to water, such that the film surface switches from a relatively hydrophobic state in dry conditions to a relatively hydrophilic state in response to the presence of water in contact with the film surface.
