Abstract
Abstract A form for erosion control structures, which is made of at least two sheets of flexible material joined about their entire periphery forming a space adapted to receive a flowable material therein, is provided with a fluid transmitting material attached to one of the sheets about its periphery for equalizing hydrostatic pressure developing between the form and the surface upon which the form rests.
