System and method for controlling water flow through ground with a geotextile comprising water absorbing material

摘要

A water absorptive material comprising a fibrous substrate impregnated with a water absorptive, water insoluble polymer, wherein the polymer is intertwined and interlocked with fibers of the fibrous substrate, and the use of such water absorptive material to form a water control zone to prevent water egress from the water control zone into adjacent ground or water ingress into the water control zone from adjacent ground.
