Anaheim Concrete Scanning Projects that Penhall Worked On

Penhall helps a large scale hotel remodel project by locating tension cables and conduit in preparation to relocate drain pipe in all bathrooms

concrete scanning to locate tension cables and conduitOver the past 6 months, Southern California analyst, Chanda has been at an ongoing project at a popular amusement park’s hotel. The hotel is remodeling all of its rooms in phases over the next year. Penhall is scanning to relocate a drain pipe in the bathrooms that are within a post tension slab, with conduit within the slab. To date over 100 rooms have been scanned using a GSSI Mini XT and a Hilti PS1000. Rebar, suspected post tension cable and suspected conduit have been found. Magic marker and lumbar crayon have been used for mark out and the client is happy with the work. Penhall looks forward to continuing to scan all remaining rooms throughout this large renovation.

Locating post tension cables using Ground Penetrating Radar

Scanning concrete post tension slab to locate cables
A general contractor hired Penhall at a Los Angeles location to use Ground Penetrating Radar to scan post tension slabs on the 20th floor of a building. The 6′ x 4′ areas were scanned prior to having openings cut into them.

Scanning concrete to identify hazards before drilling

Scanning concrete to identify hazards before drilling
In Anaheim, CA, Penhall performed concrete scanning so the contractor could perform core drilling in 5 areas within a building.  Each area to be scanned were on an 8″ thick concrete slab.  Consequently, the analyst identified the hazards, so the drilling was done in safe and timely manner.

Determine the thickness of the concrete slab

GPR Scanning to determine the thickness of the concrete slab
At another location in Anaheim, CA, Penhall inspected six different areas for obstructions. 12″ x 12′ areas were to be scanned prior to core drilling. As a result, our analysts were able to thoroughly survey the concrete slab at depths that varied between 10″ and 12″.

Before drilling, be sure to scan for any potential hazards

Concrete Scanning on slab with metal pan decking
A customer in Woodland Hills, CA contacted Penhall to scan many different areas in preparation for an extensive amount of core drilling. The locations included 128 – 4″ areas, 55 – 6″ areas, and 2 – 10″ areas. Because the 7″ concrete slab sat on metal pan decking, it made this particular project unique.
