Restoration and Waterproofing|Tunnels

THP has assessed, rehabilitated, and designed miles of walk-through tunnels weaving through institutional campuses. While some of these tunnels are for pedestrian use, most carry utilities.

Our tunnel rehabilitation work includes- waterproofing, concrete repair, upgrades, and additions to utility supports and thrust anchors. Our experience includes tunnels constructed by both cut and cover methods and boring techniques.

THP’s construction documents contain significant detail on the restoration of hard and soft landscape conditions, with the goal of leaving no trace of buried structures. We are sensitive to the temporary construction measures needed to maintain traffic flow in pedestrian and vehicular areas.

Assessed, rehabilitated, and designed over 5 miles
