Hydro vac excavation ## Water and vacuum excavation for cleaner, safer digging Hydro excavation uses high-pressure water to break up soil and vacuum suction to remove the loosened material. This makes it highly effective where traditional machinery could damage underground infrastructure or create unnecessary disruption. Across Sydney, hydro excavation is used for service proving, trenching, potholing, tight access excavation, drain clean-out, de-watering, tree root exposure, and site clean-up. We bring a family-owned, safety-first approach to every job, with 14+ years of experience and 24/7 availability for urgent works.

Tell us if the site has disposal limits, confined space, or surfaces that need extra protection. ### Use current service information first BYDA records and locator marks guide where hydro excavation should start; physical exposure then confirms the actual depth and position. ### Flag tree roots or sensitive ground Where root zones, retaining structures, or soft ground are nearby, tell us so the water pressure and approach can be adjusted. How It Works ## Safe, controlled work around live assets 1 ### Plan the dig We review the job scope, access, likely services, and the safest hydro excavation method. 2 ### Break up soil with water Controlled water pressure loosens the ground without mechanical bucket contact. 3 ### Vacuum and contain spoil The loosened soil and slurry are vacuumed into the truck to keep the site cleaner and safer. Method guide ## How hydro excavation works on site Hydro excavation combines water pressure and vacuum recovery to open ground around assets without relying on a steel bucket. 01 ### Target the dig area The operator works only where exposure, trenching, clean-out, or de-watering is needed. 02 ### Loosen with water Controlled water pressure breaks up soil, clay, sediment, and compacted material. 03 ### Vacuum the slurry The loosened material is recovered through the hose and contained in the truck. 04 ### Leave usable access Crews get a clearer view of services, roots, pits, drains, or trench lines.
