The conventional method of repairing debonding and delaminations is to remove and replace the defect. Sometimes that can entail a huge problem for the installer or owner when its a bridge deck topping, or some other facility with a large amount of square yardage -like a parking garage. Not only can the removal and replacement require a high degree of coordination efforts, the area most times has to be taken out of service which can severely impact revenue streams.
When the Washington Metropolitan Area Transit Authority was in the final stage of opening its Suitland Station, it discovered the 4" silica fume topping slab cast onto the structural slab, that was scheduled to receive a quarry tile finish, was spotted with a large number of delaminated areas. Since the platform was demobilized of equipment, and was now a literal island, this condition posed a nightmare logistical problem to remove and replace the topping...and would severely impact the scheduled opening (revenue). Tecvac, Inc. identified and verifyably put back into composite some 4,500sf of delaminated topping in-situ using its exclusive TecBondtm Interface Permeation Process and allowed the finish tile work, and the opening, to proceed on schedule.
When heavy forklift equipment damaged/delaminated a 3" topping slab cast onto T- panels on a second story warehouse floor, the disruption necessary to commercial retail tenants below to accommodate any form of removal and replacement was foremost on the minds of the owner and the property manager. At the very least, an R&R operation would necessitate vacating the occupant tenant and all of the tenant businesses beneath the warehouse (125,000sf) to temporary off-site facilities. Then, when the repair was complete, moving all the tenants back into their spaces. A costly endeavor to say the least but, without some alternative, there was no choice; since the T-panel ceilings above the retail spaces would occasionally deposit concrete chunks on desks and equipment below. Working at night, technicians identified (Impact Echo survey...more later on this non-destructive testing method) and verifyably re-bonded 35,000sf of delaminated area in just 20 days...independent pull tests broke in the substrate at over 200psi and the floor was verified safe with load testing. Noteworthy, the operations did not necessitate the displacement of the occupant or a single tenant located below.
