The theory behind vacuum excavation is simple, it digs a hole in the ground by penetrating hard soils with pressurised water to break up the solid state into a slurry. The loose soil is then vacuumed through a hose into a collection tank for later disposal. A pothole is created safely exposing the service without the risk of damage or injury to the operator.
Once a locator has located the utilities, the vacuum excavation truck comes on site to expose the service. No waste or spoil is left at the point of excavation. Ideal for those situations where the spoil potentially is contaminated or would add to the size of a secured work site or road closure situations and high public use locations.
It is much more time effective than hand digging and less risk of manual handling injuries reducing occupational Health and Safety issues for staff and their employers.
Used for our customers in locating underground assets. High pressure water and air units expose electrical cables, underground pipes and conduits that may be considered potential threats to customers projects.
The reduced risk with hydro vacuum excavation (NDD) provides an alternative method to jackhammering and drilling, without damaging surrounding materials, and with reduced noise pollution and disturbance to neighbouring surroundings. The increased safety levels give operators and customers added peace of mind, as well as increased productivity and efficiency as time spent rectifying damages are eliminated.
Our range of applications include:
- Potholing of gas, water, sewer and telecommunication lines
- Excavating around gas, water, sewer and telecommunication lines
- Straightening of power poles
- Coring to enable soil samples
- Tree planting and remediation
Our specialty vacuum loading equipment offers quick and effective removal of all wet and dry waste products.
Our vacuum loading services are particularly effective for confined spaces and pits. All vacuum loaders are EPA licensed and our operators have completed extensive training on procedures, safety requirements and environmental responsibility.
Debris tanks range in size from 2,000 litres to 20,000 litres. Our equipment can collect many wet and dry substances, including concrete slurries and cement, woodchips, wet and dry clays, brick residue, liquids, glues and adhesives, oils and carbon-based materials and sewage.
Typical areas where vacuum loading is suitable:
- Tank and vessel cleaning
- Pit and culvert cleaning
- Clean-up of environmental spills
- General housekeeping
