5203 |a"The purpose of this project was to develop and evaluate means of making basement floors airtight, with the objective of keeping out radon bearing soil air. The main elements of this project were laboratory tests of the airtightness of several floor assemblies, and a field test of the airtightness of a floor in a real house. In the laboratory tests, several arrangements of polyethylene films were tested, as seals of the floor-wall joint, and as crack seals. Also tested were concrete slabs without polyethylene films, and a concrete slab with a crack created and sealed with a waterstop strip. The results of the laboratory tests showed that a lapped and caulked polyethylene film can be used successfully to make cracked concrete airtight. They also indicated that the use of a waterstop could be a successful technique"--Abstract., p. i.
