Ground Penetrating Radar
Ground penetrating and hydro-excavation done by the experts.
What we do
PPS uses a high-powered GPR to track certain metallic or non-metallic materials underground.
This includes underground water, gas, electrical, telecommunication, fibre optic, sewer and stormwater services as well as significant tree roots.
One of the key pros of this is that it minimises the risk associated with exploratory excavation.
Next, it’s then followed by hydro-excavation or potholing, a form of non-destructive digging and vacuum loading.
This will now expose the area around the services for visual inspection prior to regular excavation.
This excavation will further decrease the risk of damage significantly.
A GPR transmitter is a unit that can be carried, mounted on a cart and towed.
For example, to assess a section of road pavement, the GPR can be towed at over 80 km/h.
Take note that there will be no disruption to traffic.
With that, all data is collected with high horizontal and vertical resolution, allowing precise location of the underground object.
Using a high-pressure water lance, our hydro-excavator breaks up soil, clay and other earth without damaging the service.
The powerful vacuum unit then removes the spoil.
Potholing is recommended when conventional digging is too dangerous or impractical.
This will offer a safe way to dig around utilities such as:
Gas, Telecom cables, Fibre optic cables, power cables, water pipes and sewer and stormwater pipes, as well as significant trees.
