Institutional Masonry / Concrete Repair and Waterproofing
Through-Wall Flashing at Rock County Jail (Leak Repair)
As with so many structures, the Rock County Jail’s original through-wall flashing was installed improperly. We were hired to install approximately 750 lineal feet of new through-wall flashing. This entailed removing approximately 5,600 bricks, priming and painting the steel lintel, installing the through-wall flashing system and reinstalling the brick masonry.
Bottom Side Concrete Beam Repair with Epoxy Grout
Two concrete beams located below an indoor pool had been in contact with chlorinated water over a long period of time. This caused significant deterioration of the concrete beams and loss in the volume of the reinforcing steel. A third party structural engineer was consulted to design a repair that could withstand these conditions.
In order to repair the beams and bring the structure back to better than full strength, we added supplemental steel to the corroded rebar. Then, we treated the rebar with a special anti-corrosion primer to help limit the amount of future corrosion both within and outside of the patch location. To ensure proper strength was developed around the rebar and to help limit the amount of galvanic corrosion, we used an epoxy grout to repair these locations.
Sealant Replacement at Red Granite Correctional Facility
The Red Granite Correctional Facility was experiencing widespread leaks throughout its campus. We were selected to install a double-stage sealant joint, which required the removal of approximately 27,000 lineal feet of existing sealant. We also installed a through-wall flashing system below large HVAC louvers to prevent water from flowing downward through this wall.
