Excavac

Excavac Excavac has operated since 2007 providing a range of non-destructive excavation services.

We specialise in ‘open hole’ excavations for exposing sensitive utilities such as water and gas mains, power cabling and other buried utilities. From excavating around gas, water, sewer and telecommunication lines to commercial and residential remediation and environmental work, our non-destructive hydro vacuum system avoids the problems associated with damaging valuable underground assets caused

by traditional drilling and jackhammering methods. Excavac’s team of professionals are fully licenced and trained to assess your needs on-site – on time and on budget. Whether post hold digging, pit clearing, safe excavation around fibre optic, gas, water or sewer works – we have the solutions. From civil construction and large infrastructure works to problems around the home – our highly trained and friendly staff are there to guide you every step of the way. Since 2007 we’ve been a trusted name in the hydro vacuum excavation, potholing and vacuum loading business. Our client list includes a range of civil contractors, business and government entities with work from high-rise business centres through to warehouses, roads, rail and residential. We are also proudly a gold rated service provider to groups such as Endeavour Energy. Excavac is proudly Australian owned and operated, providing services to the Blue Mountains, Illawarra, Southern Highlands & Sydney metropolitan areas.

Did you know? In Australia, underground utilities can be buried anywhere from 300mm to over 1.5m deep depending on the state. That’s why hydro-vac excavation is the safest way to dig. Excavac protects what’s underground — every time.
