CONCRETE SCANNING WITH GROUND PENETRATING RADARWith new build construction and renovation projects, the likelihood of needing to cut or core a concrete slab is high. There is inherent risk of striking rebar, electrical and communications conduits, and post tension cables during cutting, coring or drilling process. The cost of such mistakes can be prohibitive. Unreasonable constraints on already thin budgets can occur, as well as infusing havoc into your schedule and creating a safety hazard for your employees. Our well-trained, skilled, experienced technicians respond quickly to service requests, especially when your need for concrete scanning is a last-minute discovery. The end result is professional, accurate and timely scanning – the exact satisfaction you’re seeking to mitigate risk and keep your employees safe.
DETECTION OF REINFORCING STEELGPRS-trained technicians are able to locate rebar and post-tension cables within the concrete using GPR technology. Reinforcing steel locations are marked directly on the work surface to ensure safe and efficient drilling that will preserve the integrity of the structure and reduce the need for repairs or patching. This helps our clients conduct core drilling without accidents, injuries or delay. GPR scanning is also useful when preparing for a renovation that includes electrical outfitting, plumbing, fire protection services, drain installation and duct work.
LOCATING EMBEDDED ELECTRICAL SERVICESWhen core drilling or saw cutting in commercial and industrial locations, accurate detection of electrical conduits is essential for preventing safety risks, power outages and costly damages. GPRS provides two specific but different scanning services in this area: Elevated concrete slab scanning and concrete slab-on-grade locating. Elevated concrete slab scanning involves detecting embedded electrical conduits prior to core drilling a hole through the slab. Concrete slab-on-grade locating – a concrete slab poured directly over dirt – involves scanning a trench line for conduits before conducting saw cutting and trenching to install a sanitary pipe, water line or something similar.
CONCRETE ANALYSISAlso crucial in the scanning process is determining what’s in the concrete structure. This includes gauging the concrete thickness, what the rebar content is, its spacing and its elevation (depth) in the slab. This extensive, critical information helps our clients’ engineers understand the makeup of the concrete.
VOIDS DETECTION AND LOCATIONSThrough their extensive training and experience, GPRS technicians have the ability to locate voids – air gaps between the sub-grade, dirt and the concrete slab-on- grade – hidden below concrete or asphalt surfaces. This degradation occurs over time due to compaction, pipe ruptures or erosion but is often undetectable on the surface. GPRS ground penetrating radar technology can help our clients locate these areas and – most important – avoid collapses.
Our equipment is second to none. We utilize the latest GPS technology to pinpoint subsurface utilities, map their locations and develop detailed AutoCAD reports for our customers.
