Test water penetration walls
Prior to mounting the apparatus to the wall, the chamber is sealed to the wall utilizing various different types of sealants to keep the chamber relatively water tight. Reasons To Test Masonry Walls For Moisture Penetration There are many reasons for this test to be performed by general they fall under just a handful of categories. Once the test is underway, water is continually sprayed for four 4 hours onto the specimen. Outside of the chamber, water is pumped from a holding tank or reservoir at a rate of 3.

Water Penetration Testing
ASTM C Water Penetration of Masonry Wall Surfaces | Los Angeles
Masonry walls are constructed to control water. Whether they are mass walls or cavity walls, understanding how it handles water is key to identifying moisture and leaks. BECS will help identify how the porous masonry absorbs water, how much water penetrates, and check to see how penetrating water is evacuated back outside. Coatings, membranes, and sealants all have specified requirements to properly stick to a surface properly.

Wall Penetration and Drainage Testing
Significance and Use Excessive water penetration of masonry may degrade masonry wall performance with respect to thermal conductivity, durability, efflorescence, staining, corrosion of embedded metal items, and water leakage. This non-destructive test method contains procedures and equipment requirements to quantitatively determine the surface penetration of water at a single location on a masonry wall and may be used to evaluate masonry walls in-situ or for field mock-up testing. Common applications of this method have been comparison of water penetration rates of walls before and after repairs. Resistance to water penetration is dependent on materials, workmanship, design, and maintenance.
BDG performs field-testing procedures relative to evaluating the performance of installed windows, doors, storefront, curtain walls, sloped glazing systems, skylights, ribbon windows, and exterior building facades for new construction quality assurance and diagnostic services to determine the cause of water intrusions. Read More. The outer wall surface of a masonry wall will experience water penetration when subjected to wind-driven rain. The resistance to water penetration is dependent on materials, workmanship, design, and maintenance. Storefront and curtain wall systems are similar in appearance but differ in the way water drainage mechanisms are used.
