Standard Guide for Standard Details for Adhered Sheet Waterproofing
SIGNIFICANCE AND USE
This guide illustrates general details for below grade and plaza waterproofing. It serves as a guide that will enable the designer to prepare complete waterproofing details for each specific condition that occurs on a project.
SCOPE
p>1.1 This guide covers details for typical conditions encountered in adhered sheet waterproofing on below grade structures and plazas.
1.2 This guide does not cover liquid applied waterproofing.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
