Hydro Excavation Services – Reducing Excavation Risks and Improving Efficiencies

Hydro Excavation Services – Reducing Excavation Risks and Improving Efficiencies

Traditional methods for digging and excavation don’t always work, especially in congested areas with high vehicular traffic and footfall, and residential complexes where noise is not desired. In many construction projects, both subsurface utilities and underground facilities are key elements that need to be protected in any digging, excavation or loading process. When there are pipes, wires, conduits and other utilities buried in the area being dug up, a more modern approach has to be taken.

Hydro excavation services offer a non-destructive digging and excavation process that consists of injecting pressurised water and a vacuum system to dig out the soil, leaving a trench completely open, leaving no scope for cave-ins and the disastrous events which can follow a cave-in. It provides a safer way for debris removal using advanced methods such as vacuum digging and vacuum loading. These methods are highly effective to employ in congested areas, as the equipment can be positioned at a distance from the excavation site. Hydro excavation services are frequently used for sewer and pipe rehabilitation and pole installations. In terms of landscaping, hydro excavation services result in minimum damage to the surroundings soil, leaving it more firmly compacted.

Equipment can be placed away from the digging location Hydro excavation services work by injecting water into the ground through a hose, liquefying the soil. When the soil becomes a slurry mix, it is then vacuumed using a powerful pumping system which transfers the wet soil mix into a truck. The process can be used to dig up to 70 feet or more, with powerful equipment that can be positioned away from the actual digging area.

Safely excavate in congested areas Hydrovac methods provide a safe way for excavation while minimising disruptions and damage to the existing infrastructure and underground utilities. The process ensures that the surrounding soil and utilities are not disturbed.

Hydro excavation services can be used to excavate in tight spaces, planting strips, or in backyards with limited spaces. This controlled excavation method offers the safest way to dig in cold weather excavations, without exposing the workers to very low temperatures. Hydro excavation services are advantageous when working on frozen ground, since hot water can be used to thaw and break up the soil. The method is ideal to locate utilities or when small diameter pipes are to be installed.

Non-destructive cleaning method As a form of non-destructive cleaning, vacuum loading is used by excavation services providers to safely remove only the required material, while leaving the surrounding areas and infrastructural utilities undamaged. Vacuum loading is preferred for removing debris from a limited space where traditional methods cannot be conveniently implemented. It is used for the safe removal of hazardous liquids, sludge and fine-loose materials.

Trucks used in vacuum loading have pumps that provide suction with enough power to suck materials and deposit them in a truck for disposal to a designated space. The recovery equipment does not have to recover and load the material into a different vehicle. Instead, it is diverted to an attached tank, thus increasing the speed of execution, and saving time and costs.

Hydro excavation services providers use trucks equipped with unique features such as a compressed air lance, vacuum suction, and a waste storage chamber. These vehicles come in a range of different tank sizes.

Vacuum loading is a method which is not labour intensive, and is a great option for many projects.

• With fewer people required for the removal of waste and debris when utilising these processes, and less expenses on insurance and damage, vacuum loading offers an affordable and environmentally friendly waste removal method. Improved efficiency associated with vacuum loading increases cost savings in the overall excavation and digging process.

• Hydro excavation services combine high-pressure water with an air vacuum. High-pressure jets cut and break the soil, while an air vacuum removes the slurry produced, from the location to a debris tank. The vacuum space can be provided by hydro excavation services either through a positive displacement blower, or a fan system.

Minimising health risks to workers Vacuum loading, vacuum digging and hydro excavation by Aussie Hydro-Vac Services allows the excavation personnel to work remotely, reducing the chances of inhaling hazardous gases and associated health risks for the field workers. The company uses high-velocity vacuum loading and vacuum digging units for relocating materials such as sand or gravel piles, easily and economically.

Aussie Hydro-Vac Services’ vacuum digging, vacuum loading and hydro excavation services are performed by highly-skilled operators, with a fleet of modern, compliant and well-maintained vacuum trucks.

A safer and lesser damaging excavation method can lead to a reduction in insurance and liability cover for an enterprise or residential project, and also results in fewer leaks, repairs and replacements. Vacuum digging, vacuum loading and other hydro excavation services provided by the Aussie Hydro-Vac Services are more accurate, cost-effective and result in less need for back-filling. This will lead to an improved bottom line for your debris and waste removal services. Hydro excavation services provided by the Aussie Hydro-Vac Services are environmentally friendly compared to the traditional destructive alternatives.
