ABSTRACT:
A pillow adapted for use as a soil filtration and water drainage device. The pillow includes a plurality of substantially oblong, rounded, noncompressible, noncollapsible, water resistant, non-biodegradable, and nonflammable pellets. The pellets are normally about one-half inch to two inches long. The pellets are enclosed by an outer, flexible membrane permeable to water, but impermeable to soil. Thus, water, but not soil, may pass through the membrane and around the pellets. The pillow is deformable, yet sturdy and readily adapts to the shape of the surrounding soil and other materials. Moreover, the pillow is lightweight and inexpensive.
