Concrete Block walls (CMU) are a commonly used construction method – yet once a block wall is built, it can be almost impossible to visualize issues within the NJ block wall. Thermography- Block Wall Scan IR is a non-destructive method to inspect CMU for proper grouting and insulation (including areas of missing grout and insulation) and to ensure proper location of structural components.
Block Wall Scan IR NJ- Infrared Inspection method of concrete block walls is the unsurpassed way to visualize structural integrity of the grouted cells or missing reinforcement in the entire Block wall section. Infrared testing can be performed at any time during the construction process without delaying or interrupting any other trades or affecting the progress of the building progress.
Infrared thermography can be utilized as a building quality assurance tool. As well as due diligence real estate transactions, Almost all building materials will retain heat energy and therefore can be checked for quality of installation. Improper installation of insulation and/or seals in buildings can be seen in the form of heat loss and air & water leaks. Also, building components “inside” the walls, ceilings and floors are recognizable because of their differences in mass. For example, infrared thermography can be used to determine the presence and correct placement of grouted cells in concrete block walls. If the owner of a new block building spends a little money checking their (the low-bidder’s) work with infrared thermography, the contractor will be forced to build the building per specifications or face the added direct cost of repairs and resulting loss of schedule repercussions and not to mention law suit.
In the past construction professionals think the only way that one can know whether quality work of the grouted cells, insulation and, other crucial components of the block wall are properly placed is to open it up with destructive or invasive methods, where the grout or insulation is supposed to be and see if it is there. However, this method of testing is destructive and time consuming as the small holes do not show where blockages and/or too much grout exist. Which means you could have massive structural integrity issues only a few feet away from the hole! The most popular way to make sure that grouting and rebar in place is to require the builders to install an inspections port, cut into the block faces. This is a very costly, time-consuming and sloppy methods.
If voids are present in the grouted cells, they can reduce the structural capacity of the systems and, in the case of reinforced masonry, can limit the effectiveness of the steel reinforcement. These voids often collect water, leading to interior damage and corrosion of the reinforcement. Today, infrared technology is the best tool for the surveying of a masonry wall to find deficiencies in the structural components. It’s a fast, inexpensive, and accurate method of quality control of grouted masonry.
