Concrete Scanning with Ground Penetrating Radar. With 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.
Concrete scanning uses ground penetrating radar (GPR) to locate objects. GPR is a mechanical and geophysical device that uses radar pulses to create a subsurface image. It is non-invasive, non-destructive, and typically takes very little time. All types of construction projects use GPR to locate numerous subsurface objects to ensure safety and integrity in the construction process.
Establish Location and Depth of Post-Tension Cables in Concrete with GPR. StructureScan helps concrete professionals and contractors find the location and depth of post-tension cables. Let StructureScan identify the characteristics of the survey area, such as where the cables drape, for added safety.
Concrete and construction professionals use ground penetrating radar to safely locate structures within poured concrete prior to drilling, cutting or coring. Take advantage of locating targets in real time, with only single-sided access required.
When 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.
Through 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.
