Concrete Scanning Texas

Concrete Scanning

Whether it's a renovation project or new build construction, the likelihood of needing to cut or core concrete is high. There is an inherent risk of striking rebar, conduits, and post tension cables during the cutting or coring process. If a striking occurs, repair costs begin to add up, delays creep into your schedule and it creates a safety hazard for your employees.

Post Tensioned Cables Located Prior to Drilling Anchor Locations at Whole Foods in Houston, Texas

Prior to drilling and installing over 100 anchor and concrete core locations for new plumbing, electrical and HVAC systems, a local general contractor subcontracted Ground Penetrating Radar Systems, LLC to scan and locate post tensioned cables throughout the entire store. The contractor knew that the concrete slab on the floor and ceiling contained post tensioned cables and wanted to avoid them for the duration of all drilling. This was the contractor’s first time working with GPRS and after asking around other general contractors, many other companies referred GPRS as their go-to concrete scanning company. Since the anchor locations were on the ceiling, GPRS also rented and provided an aerial lift with certified Project Manager’s for the duration of the project. After mobilizing to the jobsite, the Ground Penetrating Radar Systems team was able to locate multiple post tensioned cables and conduits running in the floor and ceiling slabs.

Multiple Utilities Found at ExxonMobil Facility in Houston, Texas

Ground Penetrating Radar Systems was contacted by a special services contractor in the Houston Metro area to conduct a private utility scan in an area of concern at a local ExxonMobil facility. The contractor needed to excavate around some existing water valves for some underground maintenance on the water lines coming from these valves. Part of the facilities ground disturbance regulations was to call in a private utility locate to minimize any damage or dangers during this operation. Enter GPRS, the largest provider of private subsurface locating in the country. Within 24 hours, the Houston branch of GPRS mobilized to the site to conduct the locate. When GPRS arrived on site, the site contact for the contractor walked us to the area of concern and pointed out all the potential issues. Right away, we were able to determine that the area was going to be highly congested with pipelines, water lines and electric conduits based on just basic observation of aboveground indicators. GPRS conducted the scan using a 350Mhz GPR antenna and RD8100 electromagnetic pipe locator.
