Abstract:
A standard test does not exist to evaluate and compare cementitious waterproofing materials. The hydrostatic pressure test identified in the Federal Specification TT-P-1411A for paint, copolymer-resin, and cementitious waterproofing materials was evaluated and shown to differentiate among three different waterproofing materials. The method has the advantage over existing tests in that it can be used to test for waterproofability under either intermittent negative or positive pressures. In addition, the test is conducted under conditions expected during service of the materials and provides a means of determining the pressure at which a material will no longer waterproof. Test results for three different cementitious waterproofing systems are presented along with recommendations for proper system selection.
