Two percussion holes were put down to test the foundations of a proposed silo at Wudinna. No. 1 hole to a depth of 30 feet and No. 2 to a depth of 26 feet. Sealed tube samples were taken in Hole No. 2. The soil profile consists of 6 ft. of calcareous material overlying a sandy clay which grades into a clayey sand with depth. The calcareous horizon contains a 2 ft. to 2 ft. 6 in. thick surface. It is recommended that the foundation ring be seated on this travertine layer, provided the layer is continuous laterally, and that it is not necessary to penetrate the travertine for any significant depth. If these conditions are not possible, then all foundations should be located 8 ft. below the surface, where the bearing capacity is estimated to be greater than 2 and a half tons per square foot maximum safe. Care should be taken with drainage to prevent differential settlement.
