Drilled pier shaft foundation with hydro excavation uses pressurized water in conjunction with a hovering vacuum system to safely excavate foundation shafts of any diameter and depth.
The process starts with a simple pot hole. With the mechanical or manual vacuum system hovering the designated surface area, the operator excavates straight down in the ground, leaving a hole that is vertically straight with a relatively smooth interior wall. One of the advantages of using hydrovac applications to these type of drilled pier excavation is the mitigation of damage to volatile underground utilities.
Once completed, the hole is ready for the installation of rebar and concrete. Our crewmen are team players able to willing to assist with the installation of rebar once the hole is excavated. We understand the importance of timing when it comes to get the rebar set and your concrete poured. We will dig the hole fast, help you get the rebar set and then move on to the next hole while you get your concrete work done.
Smithers HydroVac can also hydro excavate bell-bottomed pier shafts. We also have experience hydro vacuum excavating shafts directly under existing pipelines where an augur has no access. We use industrial vacuum hose to excavation straight down in the ground under existing pipeline or other structures.
APPLICATIONS: traffic signals foundations, pole holes, transmission tower foundations, footers, pipe foundations, caissons, sound barriers, conduit racks, bridge supports, light standards, retaining walls.
