One of the more common provisions to make an earthfill dam a successful water barrier is the construction of an impervious, vertical, or slightly sloping, central clay core supported on both sides by shells of miscellaneous fill materials, that do not have to meet stringent permeability requirements. The central core has the advantage of relatively simple construction, and of protection against external eroding elements. The inherent problem is that if difficulties do arise in its performance, inspection and correction become extremely difficult. This technical note will briefly describe a problem that occurred in a clay core, a possible explanation, and some corrective measures.
