Tunnels & Pedestrian Bridges Restoration

Many local ordinances and departments of transportation require annual inspections of critical infrastructure such as tunnels and pedestrian bridges.  These structures are essential for the day-to-day operations of many facilities.  Their deterioration could have a significant impact on public safety.

Timely and cost effective maintenance and repairs programs can minimize premature structural deterioration, and help provide many years of low-maintenance, trouble-free use.

By applying the appropriate restoration and maintenance programs to specific areas of damage, we help extend the service life of your tunnel or pedestrian bridge and protect your investment.
