Penhall Technologies can help you locate rebar, pipes, post and pre tension cables, conduits and many other subsurface hazards that may be hidden in concrete. Our expertly trained analysts can also detect voids within or underneath concrete slabs. As a safety leader in the industry, contractors, engineers, and government agencies have come to trust Penhall first for safe and precise scanning services.
Concrete wall scanning is done to locate rebar and post tension cable
In Wailuku, HI, Penhall was asked to scan to locate and mark all obstructions within the concrete slab such as conduit, post-tension cables, and rebar prior to cutting three 30” x30” openings through 12” concrete wall, as well as drill three 6” cores.
Ground penetrating radar is used to ensure safety before core drilling
Penhall was asked to perform some concrete scanning at a Wailuku state office building to ensure it was safe to drill 12 – 1.5” cores in a the 5” suspended concrete slab on 3 balconies, 4 cores on each, of the building.
Locate and identify any obstructions in the concrete slab before installing anchor bolts
A five-star hotel in Kaanapali called Penhall to scan and mark any obstructions in concrete slabs in preparation for placement of anchor bolts.
Scan concrete columns to locate vertical rebar and rings
At a location in Maui, we were asked to scan (8) columns for vertical rebar and rings. The scan areas for each column were 8-10 feet high and 2 feet wide and all work occurred on a scissor lift.
Find pre-stress cables and identify their patterns with GPR
In Maui, a customer hired us to perform concrete scanning of a 150 ft area through a 6 inch plank with pre-stress cables and a 5 inch topping. Our analyst used the ground penetrating radar with the Mini HR to locate and mark the tension cables and their pattern.
