Broken underground concrete valve box
Hey everyone, looking for some professional input from contractors on how to properly handle a broken underground concrete valve box.
The box is embedded right in the middle of an asphalt driveway where vehicles drive directly over it. We still have the thick, heavy metal cover plate, but the precast concrete housing underneath it is severely deteriorating. The top-left rim and side walls are completely crumbling away, meaning the plate no longer has enough structural support underneath it to safely hold vehicle weight.
We currently have the area blocked off with traffic cones so nobody drives or walks onto the unstable plate by mistake, but we need a permanent, long-term solution so we can fully use the parking spaces again.
Given that the plate is still perfectly fine but the underlying concrete shelf is failing in a heavy traffic zone, what is the right way to address this? Is a concrete structure in this condition salvageable to support the plate again, or is a full replacement of the precast box the only viable option?
Additionally, what specific type of contractor should I be reaching out to for this kind of repair (e.g., a commercial plumber, an excavation/site utility crew, or a paving company)?
Appreciate any insight or advice from those who handle utility repairs. Thanks!
