Abstract
Each waterproofing job presents its own combination of circumstances and conditions that require individual attention. This is especially true of underground areas because of the variety of soils, moisture and hydrostatic pressure problems. Therefore, from the initiation of the program it was realized that only basic guide lines regarding the selection of materials and methods of application could be developed which would pertain to all waterproofing installations. This report describes waterproofing systems which are intened for below-grade applications. This report also gives observations of field investigations at 8 underground sites and the results of tests conducted at the NBS, including simulated backfill-water pressure tests, vapor permeance, impact resistance and strength. The results of other investigating labs were also considered.
