Almost every site remediation project requires the removal of contaminated soil, and there are three main ways of excavating and disposing of the soil in a timely, cost-effective and highly efficient manner.
Mechanical Excavation
Traditional mechanical excavation is where we excavate soil using anything from a 40T to 5T. These can also be fitted with a range of attachments such as a rock hammer, rock saw, ripper and pulveriser, for example, depending on the requirements of the job.
Wet Vacuum Excavation
Wet vacuum excavation is where we use high pressure water jets to break up the soil and other materials. This creates a hole filled with muddy slurry which is removed by vacuum to a secure debris tank. It’s a controlled, and safe means of excavation and particularly useful when we’re operating near utilities, or infrastructure, that needs to remain intact.
Dry Vacuum Excavation
Dry vacuum excavation is where compressed air is used to break up the soil, and then dry suction units are used to remove it. If the soil is not contaminated this process allows you to reuse the soil somewhere else on the site, if needs be. Dry vacuum can be useful in situations when we’re operating near utilities, or infrastructure, that needs to remain intact.
One of the advantages of wet and dry evacuation is that they can both be used in tight spaces. The excavator can be placed some distance away from the site, without reducing the effectiveness of the process.
Disposal Equipment
Safe and efficient transportation of the contaminated soil to a waste disposal facility is key, and we can access your site with a large variety of equipment including truck and dogs, semi-tippers, 10-wheeler tippers, 8-wheeler tippers, 3 tonne tippers, whatever is required.
