1.1 This guide describes the selection of materials, installation methods, and inspection required for sealing leaks at cracks, joints, and penetrations in concrete building walls and slabs using chemical grout. The process discussed in this guide is a waterproofing repair in which voids in a concrete element are sealed with a reactive solution installed by injection directly into cracks, joints, or penetrations. 1.2 This guide does not address the use of chemical grout for waterproofing by curtain grouting or injection into preplaced permeable waterstop tubes. This guide does not address the use of injectable materials for structural repairs or for geotechnical applications such as soil stabilization. 1.3 Units--The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
