Understanding ASTM D5957-98: Standard Guide for Flood Testing
The test must be conducted after the waterproofing membrane has fully cured, but before any drainage or protection layers are installed. ASTM International Preparation

"You're sure the structure can handle it?" the foreman asked, eyeing the massive drains Elias had already begun to plug. astm d595798 pdf free
A baseline water level is marked on the containment barrier. If the water drops significantly beyond the expected rate of localized evaporation, a leak is likely present.
The primary goal of ASTM D5957-98 is to offer a measure of confidence that a waterproofing system will remain watertight throughout its service life.
The area is subdivided with temporary dams if necessary.
Testers must account for water loss due to evaporation or wind. A control container filled with water can be placed next to the test area to measure baseline evaporation rates. "You're sure the structure can handle it
While the temptation for a free PDF is understandable, respecting copyright ensures that ASTM continues developing critical standards. For one-time use, the reading room or a $56 download is far safer and legally sound.
While accessing ASTM D5957-98 for free may seem appealing, it is essential to exercise caution:
In outdoor tests, wind and sun will cause water levels to drop. A control bucket filled to the same depth can be placed next to the test area to measure actual evaporation vs. a potential leak. 5. Draining and Post-Test Inspection

, 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.
On highly sloped decks, achieving the required depth at the high point creates excessive depth and weight at the low point.
