(Guide)Standard Guide for Preparation of Concrete Surfaces for Adhered (Bonded) Membrane Waterproofing Systems
Standard Guide for Preparation of Concrete Surfaces for Adhered (Bonded) Membrane Waterproofing Systems
SIGNIFICANCE AND USE
The success of a waterproofing application depends on, among other things, the type, smoothness, and cleanliness of the concrete surface being coated. This guide describes conditioning or repairing of the concrete surface by the removal or other constructive modification of those surface defects that can affect the performance of the waterproofing system. It also covers surface preparation by chemical and blast cleaning methods in order to provide good adhesion between the waterproofing system and the concrete as well as the effect and control of various surface contaminants. (See also ACI 515.)
This guide is not intended to offer guidelines for the selection of a suitable waterproofing system; the use of specific application techniques; or the design and installation of flashing, terminations, expansion joint details, etc. (For definitions of terms, see Terminology D 1079.)
The recommended procedures described herein are minimums; the waterproofing materials manufacturer may require more strict or specific procedures for the preparation of concrete surfaces for the application of the manufacturer’specific system.
SCOPE
1.1 This guide provides recommendations for the preparation of concrete surfaces prior to the application of adhered (bonded) waterproofing.
1.2 This guide is directed primarily toward installations of new concrete, but is also applicable for existing concrete installations. (See also ACI 116 and ACI 546.)
1.3 This guide does not apply to loose laid systems, bentonite systems, lead, or the like.
1.4 This guide does not apply to applications involving insulating concrete.
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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.
