Three Fundamental Guidelines for Choosing a Vacuum Excavator


Vacuum excavation is an ideal approach for your needs if you are planning on conducting some digging work on your property. This process is favourable because it is minimally invasive, especially in comparison to traditional trenching techniques. You should consider vacuum excavation if you are concerned about site disruptions, asset damage and spoil removal. If you choose this digging method, you will need to acquire a compatible excavator to match the requirements. Here are some core tips on selecting the best equipment for your project.

Compare Air and Water

When choosing a vacuum excavator, you should compare the air and water options. In general, these pieces of equipment are designed to use pressurised water or air to displace the spoil on the ground when digging. It is important to identify the best match for your project to ensure optimal efficiency. There are different factors that you should evaluate when comparing these two types of excavators. These aspects include safety, soil conditions and digging speed.

On-site safety is the primary priority when using heavy construction equipment. Both air and water vacuum excavators are designed to dig without a significant negative impact. However, the air option is more suitable if water could result in a chemical reaction. The ground conditions should influence your excavator choice. Hydro units have great versatility in diverse ground situations, and their speed is higher. Other vital factors include site impact, labour and clean-up. 

Evaluate the Pressure

Vacuum excavation is designed to utilise water and air under high pressure for effective digging. However, the pressure of the equipment varies, depending on the specifications of the excavator model. Therefore, if you are on the market for this type of machine, it is advisable to check the indicated pressure range.

The goal should be to find an excavator that can deliver adequate pressurised fluid to break the ground and dig as needed. But, the pressure should not be so high such that it causes unwanted damage. This is an important consideration, particularly when digging around delicate utilities. Very high pressure could cause significant losses.

Check the Spoil Tank

Finally, you should evaluate the spoil tank incorporated into the vacuum excavation equipment. The spoil tank is designed to hold the removed soil when digging. Therefore, its size will determine the amount of waste material which you can collect and move during each session. Under ideal circumstances, your spoil tank should be capable of collecting soil for an entire workday. If this is not practical, acquire one which can contain at least a half day's spoil.
