Frequently Asked Questions
What is vacuum excavation?
Vacuum excavation (also called hydro excavation or non-destructive digging) uses high-pressure water to loosen soil and a powerful vacuum to remove debris. It's the safest method for digging near underground utilities.
What is non-destructive digging (NDD)?
NDD is a safe excavation method that uses air or water to break up soil, with vacuum suction to remove debris. It protects underground infrastructure from damage.
How does hydro excavation differ from traditional digging?
Traditional digging uses mechanical excavators that can damage underground utilities. Hydro excavation uses water and vacuum—no metal contacts the ground—eliminating strike risk.
What services do you offer?
We provide vacuum excavation, non-destructive digging (NDD), ground penetrating radar (GPR), underground service locating, liquid waste removal, pit emptying, and 24/7 emergency excavation.
Do you offer same-day service?
We aim to provide same-day callouts whenever possible. However, availability may vary during high-demand periods. Contact us to discuss your timeline.
How deep can vacuum excavation go?
Our vacuum trucks can typically excavate to depths of 6+ metres, depending on soil conditions and site access.
Is vacuum excavation safe for all soil types?
Yes, vacuum excavation works on most soil types including clay, sand, and rocky ground. Hydro excavation is effective on compacted soils, while air excavation is gentler for sensitive areas.
Do I need service locating before excavation?
Yes, we recommend underground service locating before any excavation. It's required by Dial Before You Dig regulations and prevents costly and dangerous utility strikes.
What is Ground Penetrating Radar (GPR)?
GPR is non-invasive technology that uses radar pulses to image the subsurface. It detects both metallic and non-metallic objects, utilities, voids, and soil changes.
How much does vacuum excavation cost?
Costs vary based on job size, depth, soil conditions, and access. We provide free quotes for all projects.
Do you provide 24/7 emergency services?
Yes, we offer 24/7 emergency services for urgent situations including utility exposures, flooding, and emergency excavation.
What industries do you work with?
We work with construction companies, builders, plumbers, electricians, councils, utilities, telecommunications providers, civil contractors, and residential customers.
What happens to the excavated material?
Excavated soil and debris is collected in our vacuum truck's tank and transported to licensed disposal facilities.
Are your operators certified?
Yes, all operators are fully trained and certified in non-destructive excavation methods, safety procedures, and Dial Before You Dig requirements.
