Concrete Masonry Walls (CMU), commonly referred to as concrete blocks, need proper rebar and grouting to be structurally sound. (Grouting refers to the pumping of concrete into the cells of the blocks.) If not done correctly, water can collect, corrode and jeopardize structural integrity. This can result in expensive repairs and a potentially catastrophic situation.
Previously, the only way masonry walls could be examined was to hammer openings in several locations and inspection ports. While this antiquated method can indicate if the cells have been grouted, proper validation in a typical building would require hundreds of holes.
That’s why NES performs their CMU evaluations differently. By using state-of-the-art infrared technology, NES thoroughly and accurately surveys masonry walls with no costly damage—no holes!—and little disruption to the work environment. Our fast, efficient and non-invasive method of evaluating masonry walls also provides clear photo documentation of the findings for your use and records.
NES has performed hundreds of infrared cell fill inspections for schools, shopping centers, commercial buildings, government buildings and residences. We have the experience, knowledge and technology to get the job done quickly and correctly.
