The I 90 floating Bridge tunnels were experiencing leaking ground water into the auto exhaust tunnels. Pro-Seal Products technical team designed a Pro-Seal water management system to meet the need to keep the exhaust tunnels dry.
The utility tunnels at the LA Trade Technical Institute were experiencing exhausted rebar and carbonated concrete in the ceiling. This ceiling is the structural slab under the five story structure above the tunnel. Pro-Seals technical team designed a repair to repair the concrete, chemically create cathodic protection of the rebar and stop carbonation to reclaim the structural integrity of the ceiling.

Pro-Seal Products designed this system to repair the collapsing tunnel ceiling. the Pro-Seal system was designed such that the greater the downward force the stronger the upward lift of the system. materials incorporated were Pro-Seal PowerPatch Flexible, Pro-Seal DP-36, Pro-Seal CCP (Chemical Cathodic Protection) System and Pro-Seal Liquid Steel.
Pro-Seal products has materials and systems for controlling the flow of water into a concrete structure, from the inside of the concrete or masonry structure, such as basements or below grade structures, against the direction of the water flow. This type of concrete repair is referred to as Pro-Seal Negative Side or Negative Pressure Waterproofing. Pro-Seals, designed systems, are put in place during active water flow, reducing preparation time, and application time. Pro-Seals materials cure in the active fluid or water flow environments, to stop the flow and egress of fluids or water through the pours of the concrete, holes in concrete, cracks in concrete, and/or the joints of the concrete.
