Scope

5.1 This guide describes the techniques used to test for watertightness of waterproofing installations on horizontal services having a slope not greater than 20 mm/m (28201;% slope) (¹/₄ in./ft). See also ACI 515.

5.2 The structural capacity of the substrate to which the waterproofing system is to be installed should be reviewed by a licensed structural engineer to verify that the loads associated with the use of procedures described in this guide do not exceed code and design restrictions. Lateral loads will be imposed on curbs or walls used for containment of the water during the test procedures and their effect should be accounted for. The effects of equipment, planters, or other movable objects present within the test area should be considered.

Note 1—Potable water weighs approximately 1000 kg/cubic m (62.3 lb per cubic ft) at 22°C (71.6°F) or 1 g/cm²/cm depth (5.19 lbs/ft ² per in. depth).

5.3 This guide describes a procedure to test for watertightness of waterproofing installations under ponded water with a short-term hydrostatic head measuring not more than 100 mm (4 in.).

Note 2—Increasing the amount of water forming a hydrostatic head beyond 100 mm (4 in.) of water may be considered provided the impact of increased loads on the substrate has been reviewed and approved by a licensed structural engineer.

5.4 For the purposes of this guide, the installation of the waterproofing membrane and flashing should be completed and the materials fully cured. Manufacturers should specify a minimum time period for materials to cure prior to performing flood test, however, no testing should be performed during the first 24 h following installation of system materials (48 h min if materials are installed at a time when ambient temperatures are below 10°C (50°F)).

5.5 The additional loads imposed upon the structure during the test period will affect the deflection of structural items. The effects shall be analyzed by a licensed structural engineer prior to placement of additional loads. Critical locations shall be monitored during the duration of the test period.

5.6 This guide is not recommended to be used if freezing temperatures are expected to occur during the test period. Ponded water can freeze and become adhered to the waterproofing system resulting in pulling or tearing of the flashings away from the substrate or may break interior corners.

5.7 The intent of this guide is to provide a measure of confidence of the waterproofing installation to remain watertight for the service life of the system, based upon the observed performance of the system under ponded water for a limited period of time.

1.1 This guide provides the user with a method for testing the watertightness of waterproofing installations applied to horizontal surfaces having a slope not greater than 20 mm/m (2% slope) (¹/₄ in. per ft).
