Services

Electromagnetic locating is the most commonly used method to locate underground services. Using Hz or frequencies electromagnetic locating is used to trace conductive services such as copper water pipes , communication cables and electrical cables. 

GPR or Ground Penetrating Radar is used for non conductive services such as nylon gas lines , polyurethane water mains and concrete storwater lines. 

This non destructive method uses electromagnetic radiation in the microwave band (UHF/VHF frequencies) of the radio spectrum, and detects the reflected signals from subsurface structures.

Scanning suspended slabs , Precast walls , coloumns and beams for reinforcement and post tension cables is essential prior to making a penetration. At On Point we transfer the results from the scanner straight to the concrete surface in a matter of seconds and then email reports straight to the engineer or client from site. 

Mapping utilities once they have been located is typically known as survey. Although we can carry out both works at OPL , Mapping is an efficient way to get the results you need. Its a basic plan with depths of services and real time aerial image as a backing for reference. Survey on the other hand is much more in depth and complex, it involves RLs , BMs , Contours and calculations . It is commonly used for design and construction. 

Hydro excavtion or non destructive excavation is the most effective and safest way to expose underground services . Most utility providers now demand that any contactor working within a certain distance of their underground asset engage a accredited contractor to carry out this works . At On Point Locating we can assist any company in completing this work.
