At Pier (UK) Ltd, we specialise exclusively in vacuum excavation, offering a non-invasive, safe, and highly efficient alternative to traditional digging methods. But vacuum excavation doesn’t end with the removal of soil and debris – what happens to the material after it’s been suctioned from the ground is just as important.
Responsible spoil management is a vital part of our service. In this blog, we will take you behind the scenes to show you what happens to excavated material, how we handle it, and why it matters for your site, compliance, and the environment.
What Is “Spoil” in Vacuum Excavation?
In vacuum excavation, spoil refers to the material removed from the ground using high-powered suction. This can include:
- Soil
- Sand and Clay
- Gravel
- Mixed debris.
This spoil is drawn through the suction boom and deposited into an onboard sealed spoil tank on the vacuum excavation truck.
Step 1: Spoil Collection and Storage Onboard
Each Pier (UK) Ltd vacuum excavation vehicle is fitted with a large-capacity, leak-proof spoil skip. These skips are designed to minimise dust and disruption on site.
Our trained operators monitor spoil levels continuously, using in-built sensors and visual inspections to ensure safe operation at all times.
Step 2: Tipping and Transporting the Spoil Safely
In most cases, the excavated spoil is tipped in a designated area on site, as agreed with the customer.
This allows:
- Easy access for reuse or removal
- A cleaner and more organised site
- Compliance with client-specific site rules.
Step 3: Disposal
If we encounter contaminated spoil during a vacuum excavation project, Pier (UK) Ltd follows a strict internal procedure to ensure the safety of our operators, your team, and the wider site environment. This structured approach includes:
- Immediate response
- Notification
- Documentation
- Hazard control
- Client responsibility
- Resumption of work
- Incident Reporting
By following the robust procedure, Pier (UK) Ltd ensures that contaminated materials are dealt with swiftly and responsibly, reducing environmental risks and keeping your project safe, compliant, and on track.
