Significance and Use
This guide outlines general procedures for the storage and application of various prefabricated sheets made using modified bituminous materials and intended for use as below-grade and below-wearing-surface waterproofing.
The substrate used for applications described in this guide shall be concrete or masonry.
This application consists of a prefabricated reinforced modified bituminous sheet applied to a suitable substrate using a bituminous-based, cold-applied adhesive or mastic. Application rates given are typical for such installations.
This guide is intended to supplement instructions from designers and manufacturers.
1.1 This guide lists application and installation requirements for fully adhered, cold-applied, prefabricated modified bituminous membrane waterproofing systems for below-grade or below-wearing-surface (such as plaza decks) vertical or horizontal applications.
1.2 For the purposes of this application guide, the substrate is assumed to be structurally sound, sloped to drain (if new construction), and meeting the local building code requirements. Similarly, the system components are assumed to comply with all federal, state, and local requirements in effect at the time of installation.
1.3 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.
1.4 This guide may involve hazardous materials, operations, and equipment. 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 requirements prior to use.
