Vacuum Excavation - How It Works


Vacuum excavation is a SAFE means of excavating for new and around existing underground utilities in any ground conditions. The system can be used ‘dry’ by agitating the ground by Air Lance or ‘wet’ in conjunction with a pressure washer, this is more suitable for heavier ground i.e. Clay, etc.

MTS Suction Excavators have the ability to work with Safely over long distances, using extension hoses material can be moved from up to 80 metres away, above or below ground.

Amongst the main benefits is its ability to work safely and efficiently around High and Low Voltage Cables.

This excavation was for Street Lighting columns, its dimensions are 450x450x1800mm and was completed in around 20 minutes.

Ground Investivation


We have the capabilities to work on Live Petrol Station Forecourts and Fuel Terminals along with Petro-Chemical Plants. Our fleet of MTS Dino3’s and Vac-Tron units are fitted with Exhaust Spark Arrestor and Chalwyn Valve, for working in High Risk Areas.

Here we are carrying out Keyhole Site Investigation holes to a depth of 2.5 Metres on behalf of ESSO. The system can also be used in conjunction with Ground Penetrating Radar and as an Audit tool for Geo-Phys.
