Underground Structures

THP is highly experienced in the restoration of underground utility vaults and tunnels. Our services include condition assessments, waterproofing, concrete repair, structural upgrades, and additions. Many tunnel projects include the repair or replacement of utility supports and pipe anchors.

THP assesses and rehabilitates miles of walk-through tunnels weaving through institutional campuses. Our construction documents address the restoration of pavements, lawns, and gardens 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, often within the public right-of-way.
