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 scanning performed on a regular basis for one large project in downtown los angeles
For an ongoing project with a large general contracting company at an up and coming luxury high rise condominium construction site in downtown Los Angeles, Penhall Technologies had yet another scanning project to add to the many scan jobs at this particular site over the past year. In this case, the general contractor needed to relocate dowels for rebar, to erect a CMU structure in an outdoor garden area. Before drilling they needed to locate rebar and any conduits that were in the slab. This work was performed using a GSSI Mini XT, a Hilti PS1000 and a RD7000 (radio detection device that picks up live electric). Penhall makes use of different tools to ensure better accuracy on each project.
Ground penetrating radar equipment used to identify hazards before cutting
Penhall went out to a location in Hollywood, CA to do some concrete scanning using Ground Penetrating Radar. We successfully identified any hazards and avoided them when the concrete was cut.
Locating electrical conduit within a concrete slab
As you may know, all hospitals require scanning before doing anything at all to the concrete in the building. So, it was a good idea for a medical center located in Los Angeles, CA to hire Penhall to complete a scanning. Here, our analysts were able to locate and mark conduit before cutting into the concrete.
Using GPR to locate rebar and conduit in CMU wall
At a jobsite in Los Angeles, CA, we were tasked with scanning a CMU wall to locate any obstructions, including structural reinforcements and any utilities, in two areas before coring 12″ x 6′ holes.
Rebar and any obstructions in concrete are accurately marked
Ground penetrating radar scanning was used at a site in Los Angeles, CA to examine two different areas that were 33′ x 33′. Penhall performed the concrete scanning in order to avoid rebar before having 4″ to 6″ diameter cores drilled.
