Before digging to repair a retaining wall, be safe by determining where all utilities are

Ensure safety by locating utilities before digging to repair a retaining wall on private propertyPenhall Technologies Orlando was called by a homeowner to locate private utilities in Windermere, Florida. The homeowner was in the process of repairing a retaining wall. Our expert Analyst was able to scan the area using GPR to locate water lines in the dig zone. A sweep of the area with a utility wand ensured that no live power would be damaged during the work. By marking the location of water lines on the surface, the homeowner could safely dig without damaging the utilities. Ground penetrating radar can be used in many other applications such as concrete scanning, detecting voids beneath the surface and underground storage tanks.

A jewelry store was being renovated and new electrical and data lines were needed which meant the contractor needed to sawcut through a concrete slab to install. The contractor was concerned about seven conduit lines that extended from the backroom to the sales floor. Penhall Technologies was able to scan the area and locate all the conduits. By using both ground penetrating radar (GPR) and a utility wand, the project was completed safely. GPR is the most accurate method for scanning concrete slab on grade.

Large scale utility locating before installing new landscaping with new electrical and irrigation lines

Large utility locate before installing new landscaping and new electrical and irrigation linesPenhall Technologies completed a large utility locating project in Gotha, FL. The customer was installing new landscaping which included new electrical and irrigation lines along the Florida Turnpike. Penhall Technologies was able to mobilize to the site and locate utilities as directed by the customer. Due to the large size of the project and site restrictions, the analysts completed the scanning by using ground penetrating radar along with a radio detection utility wand and transmitter. A 400MHZ GPR antenna was used to scan the area to an approximate depth of 5’. The utility wand can locate live power and communication lines along with direct connecting to any exposed lines. When directly connected to the line, a transmitter sends a signal through the line, allowing the wand/receiver to locate the utility. The utilities were spray painted and flagged on the surface.
