What we do

Hydro Excavation Contractors

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.
It’s then followed by hydro-excavation or potholing, a form of non-destructive digging and vacuum loading.
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.

Technology

GPR

One of the main applications for ground-penetrating radars is for locating underground utilities, particularly non metallic services such as plastic. Standard electromagnetic induction utility locating tools require utilities to be conductive. These tools are ineffective for locating plastic conduits or concrete storm and sanitary sewers. Since GPR detects variations in dielectric properties in the subsurface, it can be highly effective for locating non-conductive utilities.

Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. 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. GPR can have applications in a variety of media, including rock, soil, ice, fresh water, pavements and structures. In the right conditions, practitioners can use GPR to detect subsurface objects, changes in material properties, and voids and cracks.
Once services are identified a hydrovac unit maybe used to expose them in a non destructive method to ensure no damage to service.

Dynamic Hydro Excavation

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.
