The Teller Dam at the Turkey Creek River is located within the U.S. army post Fort Carson near Colorado Springs. The main contractor, Komada LLC, commissioned BAUER Foundation Corp. with the execution of specialist foundation engineering works for sealing off the dam against potential infiltration and the associated erosion of dam material. For this reason, the cut-off wall works are carried out in two sections: at the left abutment and at the end of the dam, approx. 12,500 square feet of secant pile wall will be created, apart from that, approx. 19,000 square feet of grout curtain are produced via injection method to seal off potential infiltration paths. The cut-off wall will be installed in the subsoil over a length of approx. 350 feet and to a maximum depth of 120 feet.
