Hydro-excavation is a method of non-destructive digging that uses pressurised water and a vacuum system to remove soil and debris. It is safer, faster, and more accurate than traditional excavation tools. Hydro excavation can be used for various applications, such as installing or locating underground utilities, landscaping, pipe and sewer rehabilitation, and more. InterGroup provides hydro excavation and air excavation to suit all needs.

We provide advanced Air-Excavation services, offering a safer and more efficient alternative to traditional Hydro-Excavation. Our Air-Excavation technology uses high-pressure air to break up soil, which is then vacuumed away, minimizing the risk of damage to underground utilities. This method is not only non-destructive but also environmentally friendly, reducing water usage and preventing soil contamination. Choose our Air-Excavation services for precise, clean, and reliable excavation solutions.

Pipeline CCTV facilitates pipeline inspection and helps to identify defects, locate features, and evaluate the pipe’s condition. CCTV condition assessment follows the 4th Edition of the New Zealand Gravity Pipe Inspection Manual and uses advanced reporting software, such as WinCan and the Moata Platform.
