ESTABLISHING THE LEAK PATH

Finding water leaks in your building can be scary. If left uncontrolled, water damage and mold could soon set it causing additional costs for repair. Finding the source leak is paramount to prevent additional water intrusion, but water is fluid and follows the path of least resistance. A sign of a leak in one area may be originating from another area, or maybe it only leaks under the conditions such as wind-driven rain.

BECS’s expert staff understands the frustrations owners, managers, and tenants face when they see signs of water. Following practices outlined by ASTM and AAMA allows BECS to perform diagnostic testing with water to simulate rainfall or wind-driven rain to identify the source of entry and to follow the leak path.

OTHER COMMON TESTS

Coatings, membranes, and sealants all have specified requirements to properly stick to a surface properly. Underestimating substrates, poor surface preparation, and inadequate installation can cause these components to separate and lose their protective values or outright fail.

When your building is leaking air, you are losing money, efficiencies, and increasing your use of energy. Testing air barriers, windows, curtain walls and other fenestrations will assist in identifying areas where air may be escaping.

Walls are supposed to keep the outside out, or at least provide a path for water that is penetrated through the masonry. When drainage pathways are clogged or caulked over, water will often find its way into the interior of the building, rather than finding a pathway back out. To understand how much water is being penetrated through the masonry, penetration testing is performed to understand recorded volumes of water penetrating under a monitored constant pressure.
