For the construction industry, the goal of encouraging safe digging and mitigating risk is key for any project. In underground utility construction, one of the safest ways to dig is the use of a vacuum excavator.
While the use of vacuum excavators in the horizontal directional drilling sector, as well as the utility locating space, is well known, its use in the trenchless rehabilitation space is a little less known.
“We’ve been in business since 1991 and lateral lining is what we do. It’s our core business,” says Chad Wilson, PPI president. “Vacuum excavation plays a huge role in what we do. The reason we are in hydro excavation is that LMK
Technologies has held – for a long time – a patented process for installing cleanouts trenchlessly called the Vac-A-Tee.”
For reference, a key component of the Vac-A-Tee process is trenchlessly digging down to the lateral via vacuum excavation to install the saddle.
More details about increased efficiencies using hydrovacs to locate underground lines are shared in a cover feature article by Mike Kezdi in the April 2022 issue of Trenchless Technology.
