ASTM Standardized Water Testing Proves That Construction Defects Exist at a Condo in Los Angeles

William Leys Waterproofing Consultants LLC was recently retained by an upscale condominium complex in Los Angeles to investigate leaks from one recently repaired deck and stucco wall on one condo unit that was claimed to be leaking into an adjacent unit, causing damages to the home.

Using ASTM approved water testing methods, we set up a spray rack that sprays up to 2 hours of rain in a twenty minute period to mimic actual weather conditions.

A spray rack set up against the wall imitates rainfall against a building in an industry standard testing method. These racks are calibrated and tested to meet requirements under ASTM testing methods.

Using our methodical testing approach, we were able to prove that the wall shown in the photograph above was in fact leaking. Using litmus paper and visual observations during the methodical cyclic testing as prescribed by ASTM showed conclusively that the newly repaired wall was in fact leaking at four locations.

Litmus paper has changed color, showing that water is leaking through or past the weather resistant barrier, and water is visible on the right side of the photograph where improper laps leave the stucco wall exposed, allowing water to enter dry space.

With this proof in hand, the Association can now move ahead with correcting the deficiency and fix the interior space. Liability on the proper responsible party that created this defect can now be established and legal counsel can now move forward with making claims against the contractor and his insurance company. Without standardized ASTM testing their claim would be very difficult to support in a court room.

A Flir Thermal Imaging camera shows the path of water in blue. Thermal cameras are important to use in leak investigations as they provide secondary evidence that supports the primary evidence.
