Repairing concrete dams with cement-based grouts: Case histories

Abstract

Some successful rehabilitation schemes involving the use of cement-based grouts for the repair of cracks in concrete dams are described. The author reviews the advantages and drawbacks of using cement-based materials in the context of the four main types of concrete dams (gravity, buttress, arch and multiple arch-buttress structures). These and other successful case studies can serve as guidance for future rehabilitation schemes.
