ASTM C1306/C1306M-08(2023)
(Test Method)Standard Test Method for Hydrostatic Pressure Resistance of a Liquid-Applied Waterproofing Membrane
Standard Test Method for Hydrostatic Pressure Resistance of a Liquid-Applied Waterproofing Membrane
SIGNIFICANCE AND USE
5.1 This test method is used as a screening tool to determine the hydrostatic pressure to which a liquid-applied waterproofing membrane may be subjected without failing when stretched over a crack in the substrate. This test method discriminates between a membrane that is very resistant to hydrostatic pressure and one that is not. Because of the variability inherent in this test method, it is not recommended that this test method be used to set a numerical standard for hydrostatic pressure resistance. No prediction of durability at lower hydrostatic pressures can be made when using the results of this test method.
SCOPE
1.1 This test method describes a laboratory procedure for determining the resistance of a waterproofing membrane to hydrostatic pressure.
1.2 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations.
1.3 There are no ISO standards similar or equivalent to this ASTM 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 nonconformance 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 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.

9.2 Follow the manufacturer’s instructions for mixing and
preparing membrane materials for testing.
9.3 When a primer is required by the membrane
manufacturer, use the primer as instructed by the membrane
manufacturer.
10. Procedure
10.1 Application of the Membrane to the Test Substrate:
10.1.1 Prepare four specimens. One will be used for the
rapid screening test and the others will be used for the
long-term test.
10.1.2 Measure the thickness of each block to the nearest
0.025 mm [0.001 in.] using vernier calipers. Record this value.
10.1.3 For self-leveling membrane materials, lay the bound
blocks on a sand bed and level them. Apply 50 mm [1 in.] wide
masking tape around the perimeter of the joined test substrates
so that approximately half of the width of the tape protrudes
above the test surface on all four sides to form a dam. Add
sufficient material to yield a dry film thickness of 1.5 6 0.1 mm
[0.060 6 0.005 in.]. Check the coating thickness with a wet
film gage. The film thickness may be built up in several coats
if specified by the manufacturer.
10.1.4 For non-sag materials, stretch a rubber band around
the perimeter of the substrate to keep the joint closed. Apply a
film of membrane at a dry film thickness of 1.5 6 0.1 mm
NOTE 1—All parts made of schedule 80 PVC. [0.060 6 0.005 in.]. Ensure that the material is a uniform
thickness by using a draw-down bar or similar device.
