Site work, vault repair and waterproofing

Vault repair below the sidewalk, with the waterproofing systems that keep the space beneath dry once it is closed back up. Vault work sits in the public right of way, so the structure below and the walking surface above are part of the same job and the same program of protection.

Waterproofing here is not a coat of something at the end. The membrane and its terminations are detailed as the structure goes back together, because that is the only point at which they can be installed properly, and a termination reached afterwards is a termination that will leak.
