The additional weight of the water can affect the deflection of structural items. A structural engineer should often be consulted to ensure the deck can handle the weight.

The area is subdivided with temporary dams if necessary.

Prevents the burial of defective membranes under concrete slabs, pavers, or soil, where repairs become exponentially more expensive.

, officially titled the Standard Guide for Flood Testing Horizontal Waterproofing Installations , is the premier industry guideline used by engineers, contractors, and building inspectors to verify the watertightness of horizontal structures. First approved in 1998 and reapproved over the years (such as its ASTM D5957-98R21 iteration), this standard outlines the procedural steps required to construct a controlled temporary flood over a waterproofing membrane. By creating a short-term hydrostatic head of water up to 100 mm (4 inches) deep, inspectors can effectively verify whether the system will remain completely leak-free before protective layers or finishes are laid over it.

In the construction and building envelope industry, ensuring that horizontal waterproofing systems — such as those on plaza decks, roof terraces, podiums, and below-grade slabs — perform as intended is critical. Water intrusion can lead to structural deterioration, mold growth, tenant complaints, and costly repairs. ASTM D5957-98 (reapproved 2017) provides the industry’s benchmark standard guide for flood testing these installations.
