1.1 This guide describes the design and installation of cold liquid-applied elastomeric waterproofing membrane systems that have an integral wearing surface. The cold liquid-applied elastomeric waterproofing membrane (membrane) to which this guide refers is specified in Specification C957.

1.2 Concrete Slab-on-Grade—Waterproofing the upper surface of a concrete slab on grade presents special problems due to the possibility of negative hydrostatic pressure causing loss of bond to the substrate. Consideration of these problems is beyond the scope of this guide. Consult the membrane manufacturer for recommendations when this situation exists.

1.3 The committee having jurisdiction for this guide is not aware of any similar ISO standard.

1.4 The 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.

1.5 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. For specific hazard statements see 15.4.

4.1 This guide is divided into two sections which provide design and specification guidelines for the use of a cold liquid-applied elastomeric membrane with integral wearing surface for waterproofing building decks in building areas to be occupied by personnel, vehicles, or equipment.

4.2 The intent of Sections 5 – 11, Design Considerations, is to provide information and design guidelines where a waterproofing membrane with integral wearing surface is to be used. The intent of the remaining sections is to provide minimum guide specifications for the use of the purchaser and the seller in contract documents.

4.3 Where the state of the art is such that criteria for a particular condition is not as yet firmly established or has numerous variables that require consideration, reference is made to the applicable portion of Sections 5 – 11 that covers the particular area of concern. Section 16 describes the repair, rehabilitation, and replacement of the membrane.
