Inspections before Cutting or Core Drilling
We specialise in providing inspections to locate Services and Structural Elements up to 1.0m depth inside Concrete before Cutting and Core Drilling such as;
- Post Tension Cables
- Structural Reinforcement
- The location of Structural Beams
- Power, Data & Lighting Circiuts (including C-Bus Systems)
- Emergency Speakers and Fire Control Circiuts
- PVC and Metal Pipes

Let us make sure you have a safe place to Cut, Core or Drill.
Ground Penetrating Radar ( GPR ) is completely safe and is more Cost Effective than radiography methods. A Ground Penetrating Radar Inspection can be performed during normal working hours with no need for costly disruptions to your worksite.
Radiography methods involve the use of Radioactive Isotopes (Iridium192) which gives off Harmful Radiation, not just during the radiographic process, but constantly, the whole time the radioactive isotope is in your worksite. This also requires the set up of safety perimeters, which requires the removal of all affected personnel in the work area.
