Hydro excavation is a safe, cost-effective and non-destructive digging method used for locating underground services where the area is unknown. This applies in areas where the assets have not been identified on site plans or where the risk of damage is high.
Hydro excavation presents several clear advantages over other digging methods like jackhammers, drills and excavators such as:
- The depth, speed and digging area are more easily controlled
- No digging permit required as it utilises a non-mechanical ground entry
- Can be deployed in hours
- Reduces damage risk to underground assets such as cables and other site services
- Can be done 30 to 50 meters away from the roadside or access areas
Unlike traditional digging methods such as hand digging, hydro vacuum excavations are much faster and more effective, taking minutes compared to hours using traditional methods. Hydrovac excavation services are also safer and much more accurate as the digging speed, depth and area can be controlled much more easily, reducing the risk of damaging other assets.
Post hole digging
Hydro vacuum excavation services can also be used to create holes for utility pole insertions. Poles created may be friction piles or end-bearing piles, depending on the need.
Trench excavation/sump and drainage sinkage
It can also be used for trench excavation and sump and drainage sinkage. The ground area where pipe work, cables or drainage sumps and systems are removed by utilising water and vacuum instead of manual and automated digging machines.
