Abstract
A subsurface support includes a protective outer member that encases an interior support member. The inner support member may typically be a steel or iron rod which is held within the outer tube as by grout or cement. The outer tube is preferably emplaced by forcing the outer tube into the ground by use of a launching device. The distal end of the outer tube is pointed thus allowing easier penetration of the outer tube into the ground. The subsurface support may be used in numerous functional ways to provide support for an overlying man made structure, or to stabilize surrounding rock and soil. The support can be used in compression, tension, bending, and/or shear.
