Hydrovac Excavation
Siteworks was established in 1992 by husband and wife Dave and Janet Stewart, covering all aspects of civil and site works.
Precise and Safe Hydrovac Excavation
Siteworks delivers precise and safe hydrovac excavation services throughout Auckland, utilising advanced non-destructive techniques that protect existing infrastructure. Hydrovac excavation combines the use of high-pressure water jets and powerful vacuum suction to safely expose underground utilities such as gas lines, electrical cables, fibre optics, sewer systems, and waterlines without causing damage or disruption. Ideal for projects on varied soil types, including challenging conditions such as clay, sand, gravel, and compacted soils, this technique effectively minimises risks associated with traditional excavation methods.
We’re also equipped to carry out hydrovac work on sites with limited or difficult access, providing flexible solutions where larger machines can’t reach. Hydrovac excavation significantly reduces the likelihood of costly downtime, improves site safety, and enhances project efficiency. Our extensively trained technicians meticulously execute each excavation, ensuring the preservation of infrastructure integrity and adherence to stringent safety protocols. Trust Siteworks to deliver dependable hydrovac excavation services with exceptional precision, superior safety standards, and optimal project outcomes.
Frequently Asked Questions
What is hydrovac excavation and how does it work?
Hydrovac excavation is a non-destructive digging method that uses high-pressure water to loosen soil, then a vacuum system to remove the material safely. This allows the ground to be excavated with precision while reducing the risk of damage to underground services, surrounding structures, or sensitive site areas.
When should hydrovac excavation be used instead of traditional digging?
Hydrovac excavation is best used when accuracy and safety are important. It is ideal for sites with buried utilities, tight access, soft ground, or areas where mechanical digging could cause damage. Siteworks uses this method when a cleaner, more controlled excavation process is needed.
Can hydrovac excavation safely expose underground utilities?
Yes, hydrovac excavation is commonly used to safely expose power cables, water pipes, gas lines, fibre connections, sewer pipes, and stormwater infrastructure. Because it uses water and suction rather than heavy digging equipment, it greatly reduces the chance of striking or damaging underground services.
Is hydrovac excavation suitable for tight or congested sites?
Yes, hydrovac excavation is well suited to tight, busy, or congested sites where larger machinery may not be practical. The vacuum hose can reach difficult areas while keeping disruption low. This makes it useful for urban sites, commercial properties, road corridors, and locations with limited access.
What types of projects benefit most from hydrovac excavation?
Projects involving utility location, service repairs, trenching, pole holes, drainage work, and excavation around sensitive infrastructure can all benefit from hydrovac excavation. It is also useful before directional drilling, drainage upgrades, or construction work where underground services need to be identified and protected.
