Non-destructive digging (NDD)
When you need ground opened around live utilities, delicate assets or tight clearances, precision is everything. TVE vacuum excavation (non-destructive digging, NDD) removes soil with high-pressure air and vacuum — exposing, locating and recovering underground services without the damage risk of mechanical excavation.
TVE runs a large fleet of mobile NDD and jetting/vac combo units, deployed 24/7 across South East Queensland for contractors, local governments and commercial clients.
Accurate locating and marking of underground pipes, cables and services so your crew can dig with confidence — and your project starts on time.
