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.

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.
In most cases the so-called water penetration test is well-suited for the determination of the condition of the blasting process and the blasting media in respect of possible contamination by oils and greases. For this test an initial blasting media sample is taken from the air flow separator at the blasting system. With the water penetration test, tap water is simply allowed to drip onto a pile of blasting media. Water immediately penetrates a pile of oil and grease-free blasting shot.
This is not directly comparable to overall water penetration and leakage, in which the area is defined as the amount of water traveling completely through the masonry system. 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.
