This is a method for restoring the composite bond to delaminated member areas and topping slabs. Often, this process can be performed with little to no disruption to ongoing operations or revenue stream.

 

TECVAC’S PROPRIETARY INTERFACE PERMEATION PROCESS USES NEGATIVE FORCES TO RE-ESTABLISH COMPOSITE BOND OF CONCRETE, MASONRY AND STONE EFFECTIVELY AND PERMANENTLY

 

Delaminated areas and debonding of topping slabs have left little recourse but to remove and replace the material. Using the TecBondtm Process will eliminate this disruptive operation. When the area is identified, this negative force process draws repair material into the delamination zone, into the finest width of cracks, smallest voids and interconnected micro-fissures, and will totally restore the composite nature of the member and material.

 

As an expample, when the Washington Metropolitan Area Transit Authority was in the final stage of opening its Suitland Station, it discovered that the microsilica topping slab, that was soon to receive finish quarry tile, was delaminated. This posed a severe logistical problem and threatened to delay the scheduled opening. Tecvac, Inc. was summoned to offer solutions. Short of removal and replacement of the deficient topping, the only answer was Tecvac's TecBondtm Interface Permeation Process.

 

After hammer sounding the slabs to identify delaminated areas, WMATA selected three areas to perform testing. The TecBondtm Process was performed on the designated areas. Small holes were drilled through the topping slab to intersect the

delamination zone. Moisture encountered within the delamination zone was extracted using Tecvac's HotBoxtm Crack Dryer. Effluent air measuring 90% humidity was reduced to less than 7%. Vacuum

force was applied to the dry zone and repair resin was introduced. Independent core testing concluded that the vacuum process was a total success; each of the extracted cores broke well into the structural slab, which demonstrated that the composite nature of the

bond line had been re-established.

 

By application of the TecBondtm Interface Permeation Process to the affected surfaces, vast areas can be renewed to composite bond permanently.
