Common water main vault trip hazard
The above picture demonstrates something very common, settling at the main water service vault.
If you were to open the hatch at your water meter you would see a concrete vault or box going down about five or six feet deep. Because it is sitting so low it generally does not settle. The sidewalk abutting it however is very prone to settling.
This is almost always a quick repair however the job is more complex than a typical sidewalk because of the potential for voids along the vault. In this respect it is much like a slab abutting a foundation wall.
These walks often need to be cut with a concrete saw so binding on the vault doesn’t cause fracturing of the slab.
Voids are common because water finds an easy path down along the vault, as water moves it carries particles of soil and before you know it the walk is settling and voids are developing.
The vast majority of these types of jobs are $300, our minimum job charge. Occasionally it will go slightly higher due to the voids being extensive, but that is fairly rare.
If you find this type of trip on your sidewalk give us a call, we can help.
