The 5th & Walnut parking ramp was built in the late 1960ís. Like many parking structures of its time, this ramp utilized paper-wrapped, post-tensioned tendons.

TECH Testing & Restoration was contracted in 1988 to repair a portion of the floor using the P/T Fix™ method for repair after the owner began noticing spall outs on the underside of the slabs.
