This specification describes the required properties and test methods for cold liquid-applied elastomeric-type membranes for waterproofing building decks and walls subject to hydrostatic pressure in building areas to be occupied by personnel, vehicles, or equipment. This specification applies only to a membrane system that will be covered with a separate wearing course, traffic course, or backfill. After application by spreading or spraying, the membrane materials shall cure to form an elastomeric film capable of maintaining a seal against liquid water. Materials shall undergo appropriate tests and conform accordingly to the following requirements: hardness; weight loss; nonvolatile matter content; low temperature crack bridging; film thickness; adhesion-in-peel after water immersion; extensibility after heat aging; and storage stability.

1.1 This specification describes the required properties and test methods for a cold liquid-applied elastomeric-type membrane, one or two component, for waterproofing building decks and walls subject to hydrostatic pressure in building areas to be occupied by personnel, vehicles, or equipment. This specification applies only to a membrane system that will be covered with a separate wearing course, traffic course, or backfill. Note 1—See Guide C 898 and Guide C 1471 for proper application of membrane.

1.2 There are no ISO standards similar or equivalent to this ASTM standard.
