Utility Survey
Utility Survey or Underground Survey is used to check the existing underground wiring or lay new lines for water, power, fibre optics, drainage, sewage, gas and telecommunications.
The procedure is practiced ensuring that none of the underground assets are interfered with or damaged during the laying work.
This vital service lessens the construction risk for the utility owners.
This ultimately reduces cost as it helps minimise project delay and damage to other assets.
We use Electronic Pipe Locator (EPL) and Ground Penetrating Radar (GPR).
GPR is used to send radio signals into the ground, which creates an image of the pipes and cables, which are below the earth surface.
EPL is used to trace out cast iron pipes or any metallic pipes.
It can also be used by utilities that have trace wires and inactive power and communication lines.
A transducer or antenna is moved along the ground by an operator whilst GPR transmits radio pulses.
Underground buried materials, such as pipelines or wiring, bounce the pulses back, which are then stored in the GPR’s control unit. Ultimately, these signals display as different bands, which aid in complete underground assessment.
This is a cost-effective and hassle-free method of seeing what’s underground without any drilling or digging.
