Results are presented for some 65 bearing capacity tests using a 3-in. (75-mm) wide strip footing on sand reinforced with strips of aluminum foil. Three foundation conditions are considered: (1) Uniform density sand to large depth; (2) sand overlying an extensive soft layer; and (3) sand overlying a potential cavern or localized weak pocket. The vertical spacing and concentration of reinforcing layers were varied to obtain the optimum arrangement for each condition. The data show that considerable benefit may be obtained in both load settlement and ultimate bearing capacity by use of a modest amount of reinforcing.
