Jetter trucks are purpose built for non-destructive digging which greatly reduces the risk of damage to underground services and the Jetter unit cleans drains and pipes from 90mm to 1800mm in diameter. This type of excavation is also useful for bulk excavation in confined areas where it’s suction hose can penetrate over or through barriers. The unit’s root cutter attachment can cut through roots of trees which may be blocking drains. It uses a Jetter high pressure hose to flush out any blockages in drains and then the vacuum excavation module sucks out the debris, water and roots etc that the Jetter has loosened and dislodged.
