A membrance of fiberglass-reinforced polyester resin is used as a trafficable cover over a compacted backfilled crater and crushed stone base to impart strength to the repair and prevent foreign object damage to aircraft. The membrane cover is usually prefabricated from several fiberglass matting layers of chopped fiberglass strands chemically bonded to woven fiberglass roving and impregnated with a polyster resin; an anchoring system consisting of holes along the cover perimeter and torque set rock bolts are used in conjunction with special steel bushings to secure the cover to airfield pavement surrounding the crater.
