What is hydrovac excavation?
Hydrovac excavation digs with pressurized water and a vacuum truck instead of a bucket, which greatly reduces the risk of striking buried utilities. GreenFlow runs two hydrovac combo trucks for potholing, daylighting and slot trenching.
How much does hydrovac excavation cost?
Hydrovac is $1,420 for a half day (4 hrs) or $2,560 for a full day (8 hrs) all-in, with overage at $355/hr. Mobilization within 30 miles of O'Fallon is included; your final price is confirmed in a written quote.
What is potholing?
Potholing exposes a small section of a buried utility so its exact location and depth can be verified before digging.
Why hydrovac instead of a backhoe?
Water and vacuum excavation greatly reduces the risk of damaging buried lines and keeps the hole tight.
Do you work with contractors?
Yes — contractors and municipalities are a big part of our hydrovac work. Call for a free quote.
