Don’t Let Traditional Digging Methods Slow You Down

Benefits of Using TDG for Hydro Excavation

Cost-Effective & Efficient

Hydro Excavation eliminates the need for large, expensive excavators, saving both time and money compared with other manual or mechanical digging methods.

Reduces Risk & Prevents Damage

By eliminating mechanical tools, our non-destructive digging method significantly reduces the risk of damage to utilities, ensuring the preservation of underground assets throughout the excavation process.

Environmentally Friendly

Hydro Excavation allows for minimal surface disruption, reducing environmental impact and overall reducing the excavation footprint onsite. All spoil removed during excavation is captured and disposed of at a registered waste facility.

Quieter and Can Be Done at Night

Using water and suction rather than mechanical tools means the process is significantly quieter than traditional excavation methods. Hydro Excavation is well-suited for metropolitan and residential areas where noise pollution is a major consideration.
