Concrete scanning is a non-invasive method used to inspect concrete slabs or columns prior to drilling or boring in renovations and new construction projects. ACS Underground Solutions utilizes ground penetrating radar (GPR) technology for fast and accurate inspections. This technology works by transmitting waves and analyzing the reflected signals to detect any embedded objects in the subsoil. X-rays and GPR are the two main options for getting a closer look at what is inside a concrete slab, such as reinforcing bars, ducts, post-tensioning cables, etc.
When working with concrete, it is important to take certain precautions to prevent freeze damage. Concrete less than one year old that may be exposed to chlorides should have a sealer designed specifically for concrete. Additionally, the subgrade must be wetted before concrete is placed and the surface must be kept moist to prevent it from drying out too quickly. ACS Underground Solutions serves CT, NY, NJ, MA and RI to find hidden objects or abnormalities prior to concrete core drilling or saw cutting.
Concrete also makes up a large portion of construction and demolition waste, accounting for approximately one-third of all landfill waste. To avoid this problem, a capillary break should be installed at the top of the subgrade before pouring the concrete. Furthermore, concrete foundations must be designed to resist the forces created by subsoil problems, including settlement and uplift. Inspectors may not be able to identify certain types of concrete mixtures visually; however, if shrinkage cracking and control joint spacing appear excessive, it is likely due to spacing.
Concrete radiography is an older form of technology that can provide clear images of what lies beneath. It is also beneficial for concrete workers who want to learn more about pouring and finishing concrete in order to hone their skills and become more valuable to their company. In some cases, the initial breakage occurs in the aggregate and some of the aggregate separates and becomes attached to the detached concrete cone.
