1.1This guide provides recommendations for the preparation of concrete surfaces prior to the application of adhered (bonded) waterproofing.

1.2This guide is directed primarily toward installations of new concrete, but is also applicable for existing concrete installations. (See also ACI 116 and ACI 546.)

1.3This guide does not apply to loose laid systems, bentonite systems, lead, or the like.

1.4This guide does not apply to applications involving insulating concrete.

1.5This guide does not apply to applications involving lightweight structural concrete.

1.6The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.7This 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.
