I-95 Abutment Wall Cracks

Completely Filled and Verified

PermeJecttm

July, 2013

Ft Belvoir, VA When Shirley Contracting developed

cracks in a new cast-in-place concrete retaining wall, only

Tecvac, Inc. was willing to offer a full depth repair which would

satisfy Virginia DOT and Federal Highway Administration; a solid

internal repair and a clean finished appearance.

While the wall itself was imposing at 23’ high and almost

5’ thick, the cracks only measured from .1mm to .23mm on the

surface. It was not certain if some of the cracks went all the way

through the member. Tecvac, Inc. completely filled the cracks

and, to the delight of all the parties, the PermeJecttm Process, set-

up with a translucent sealing material, allowed the onlookers to

visually observe the repair resin quickly move along the fracture

line and through the entire thickness of the wall. Upon

completion, the repairs left little evidence on the surface.

The Tecvac Vacuum Processes quickly fills even the

finest cracks; they actually seek out unseen-interconnecting

cracks and voids within the matrix of the concrete members.

RIDOT Selects Tecvac To Seal

and Repair Cracked I-195

Bridge Piers and Pier Caps

June 1, 2013

Providence, RI Tecvac, Inc. has competed vacuum

permeation repairs and sealing of concrete bridge columns and

pier caps on I-195 for Rhode Island DOT.

In choosing Tecvac, Inc. to perform the remediation,

RIDOT examined the ability of the Tecvac Processes to fill even

the finest cracks and to actually seek out unseen-interconnecting

cracks within the matrix of the concrete members.

Small cracks were located, mostly in the top parts of the

piers, and were no form of threat to the structural integrity of the

member. However, the severe weather conditions of the region

were a certain warranty the insignificant cracks would entrap

moisture which would lead to more problems in the coming years.

For quality assurance, Tecvac technicians performed a

before and after assessment of the cracking with Impact-Echo

and a proprietary set-up using vacuum to ascertain the cracks did

not continue through the entire member. Using a combination of

Tecvac’s exclusive PermeJecttm and PermeNewaltm Impermeation

Processes, technicians completely filled the cracks.

Cracked Support Beams and

Columns Restored – Concrete

Strength Increased by 31%

August 1, 2012

Houston, TX Tecvac, Inc. has competed vacuum

permeation repairs to concrete beams, columns and fascia

panels at a sprawling parking garage in Houston, Texas.

Some of the support beams in the structure were

confirmed to suffer from Alkali Silica Reaction and had cracked

and deteriorated to a point of requiring the installation of safety

shoring. Using a combination of Tecvac’s exclusive PermeJecttm

and PermeNewaltm Impermeation Processes, technicians brought

the members back into composite. Independent core testing

confirmed the beams total structural restoration and increase in

strength before the shoring was removed and the members put

back in service.

A host of columns were also treated. Deteriorated and

cracked precast fascia panels were sometimes treated with

Tecvac’s imbedded stitching process prior to the vacuum

process. This method of installing and imbedding stainless steel

pins along the fracture line assured the durability and longevity of

the finished repair to the larger fractures.

Tecvac, Inc. Repairs Concrete

On Historic Centerway

Bridge In Corning, NY

August 1, 2013

Corning, NY Tecvac, Inc. has competed vacuum

permeation repairs to historic concrete piers on the Centerway

Bridge in Corning, NY. Selected by the Engineers, Fisher

Associates, Tecvac’s PermeJecttm Vacuum Permeation Process

filled cracks in the 92 year old concrete not visible during the

inspection survey.

Completed in 1921, the Centerway Bridge was so

damaged by a flood in 1972 it was deemed unsafe for automobile

traffic; it has since been used as a pedestrian bridge. The present

restoration will yield plenty of green space, park benches and

new lighting while maintaining the historic fabric.

Essential to the long term durability of the restoration,

Fisher selected Tecvac’s vacuum permeation process to assure

the total structural restoration of the archway sub-structure

support members. While the fractures were carefully identified

and mapped by Fisher, Tecvac’s vacuum process and ultra thin

repair resin went on to find and fill cracks so fine, they could not

be seen through visual inspection.
