ASTM C836/C836M-18(2022)

Standard Specification for High Solids Content, Cold Liquid-Applied Elastomeric Waterproofing Membrane for Use with Separate Wearing Course

ABSTRACT
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.
SCOPE
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 Guides C898/C898M and C1471/C1471M for proper application of membrane.  
1.2 There are no ISO standards similar or equivalent to this ASTM standard.  
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 nonconformance with the standard.  
1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview

ASTM C836/C836M-18(2022): Standard Specification for High Solids Content, Cold Liquid-Applied Elastomeric Waterproofing Membrane for Use with Separate Wearing Course provides comprehensive requirements for cold liquid-applied elastomeric membranes used in waterproofing building decks and walls exposed to hydrostatic pressure. Designed for structures such as occupied spaces, garages, and equipment rooms, this standard specifies properties and tests for membrane systems that are installed beneath a separate wearing or traffic course, or backfill, ensuring long-term water resistance and structural integrity.

Key Topics

• Scope and Application: Focuses on elastomeric membranes (one- or two-component) applied cold as a liquid and designed for waterproofing horizontal and vertical structural surfaces that will be overlaid by another material.
• Curing and Film Formation: Membranes are spread or sprayed onto surfaces and then cure to form a continuous, seamless elastomeric film that provides a watertight seal.
• Types of Membranes:
  • Type I: Single-component material, ready to use after mixing, optionally with accelerators.
  • Type II: Two-component systems that require both parts to be mixed for curing.
• Physical Requirements: The membrane must meet stringent physical properties such as minimum hardness, weight loss, nonvolatile content, ability to bridge cracks at low temperatures, film thickness, adhesion after water exposure, extensibility after heat aging, and storage stability.
• Testing Methods:
  • Hardness (durometer resistance)
  • Weight loss and nonvolatile content determination
  • Crack bridging at low temperatures
  • Film thickness on vertical surfaces
  • Peel adhesion after water immersion
  • Extensibility after heat aging
  • Storage stability evaluation

Applications

ASTM C836/C836M-18(2022) is widely applicable in the construction and renovation of waterproof structures, particularly in environments subject to water intrusion or hydrostatic pressure. Typical applications include:

• Parking garages: Waterproofing concrete decks before installing paving or wearing courses.
• Plazas and podiums: Providing a durable watertight membrane beneath landscape finishes, tiles, or pavers.
• Mechanical and equipment rooms: Protecting interior spaces from water ingress.
• Basement and below-grade walls: Applied to walls to resist groundwater pressure before backfilling.
• Bridges and elevated roadways: As an underlayment for traffic-bearing surfaces requiring robust waterproofing.

Benefits include maintaining a long-lasting seal against liquid water, accommodating substrate movement, and resisting adverse environmental conditions when protected by a finishing layer.
