Introducing the Vacuum Assisted Relief (V.A.R.) Concrete Patching Process

VACUUM ASSISTED RELIEF (V.A.R.tm) CONCRETE PATCHING PROCESS

Tecvac, Inc. has developed a remarkable process for more permanently repairing/patching concrete!

The V.A.R.tm Concrete Patching Process utilizes vacuum, and modern Self Consolidating Concrete (SCC) material, to produce a concrete patch of superior quality and longevity; especially vertical and overhead surfaces.

Conventional methods of preparation are used to extract deteriorated/defective concrete within the sawcut perimeter of the patch.  These preparations are followed by forming and sealing the entire area to be patched.  After the formed area is sealed,  Tecvac employs the introduction of steam to the enclosed area using its Hydrosattm Process of moisturizing the surface.  Prior to material introduction, vacuum ports are installed at points within the patch area and vacuum is applied; now vacuuming the void, along with the simultaneous introduction of material, eliminates void pockets and honey combing.

By using the versatile SCC material, the result is a superior bonded patch and a finished surface "smoother than a baby's butt"; all with no vibrating or segregation of the material.  In aesthetically critical conditions, the V.A.R.tm Process can be coupled with our PatchMatchtm color coordination to install a patch which closely matches the substrate.

If you have experienced failure of your patches within a short time after their installation, call Tecvac, Inc. and inquire of our long term warranties available when we patch with V.A.R.tm.

A New Innovation From Tecvac, Inc.

Bonding Agent or PreSoak?

Now Comes Steam To Prepare Existing Concrete For Patching

We all know vapor moves in concrete;Tecvac Puts It To Work!

Concrete can only contain a certain amount of vapor at a given temperature.  Often referred to as the “yo-yo effect”, as the temperature of the concrete rises and falls, so does the volume of vapor.  As the concrete cools the excess water vapor condenses within any surface void.  When the vapor turns to a liquid, capillary action kicks in and disburses the liquid. 

Use Steam To Prepare Concrete For Patching 

Vapor Moves In Concrete…We Put It To Work

In the simplest terms, the humidity inside cured concrete is largely determined by ambient relative humidity; the moisture/dryness of the air moves in and out of the concrete to become balanced.  Without getting into how temperature and water cement ratios effect the amount of moisture the concrete will hold, it is a well known fact when high levels of water vapor are trapped and condense, coatings fail and overlays, grout beds ceramic tile and stones de-bond.  Not to mention the damage which is caused from freezing water vapor within the matrix.  Yet, when installing a patch this water vapor is welcome!  Our technicians now generate this environment with STEAM!   

[Steam is an invisible gas that spreads out and expands 1600 times the volume it was when it was water.  The white plumes you see coming out of a boiling tea kettle is actually steam being cooled back into water droplets.]

For as long as I can remember, there have only been two schools of thought when it comes to preparing a chipped out and cleaned surface area for placement of cementitious patching material; applying a bonding agent (usually epoxy) or pre-soaking the area for 12-24 hours.  If you have ever done either, you are aware that, depending on conditions, both methods create their own set of difficulties, especially the former.  

Now, when Tecvac prepares a surface to receive a cementitious patching material, the high levels of water vapor generated by a steamed area is not only quick and unparalleled...it is lasting.

Tecvac Is About To Start A Revolution ...Again!!

Twenty years ago I was privileged to partake in the introduction of a revolutionary method of non-destructive testing for concrete, masonry and stone.  At that time I was operating only one of two Impact Echo Non-Destructive Testing tools in the United States ...how time flies.  Since training at Cornell University, Josh and I have performed Impact Echo Testing on concrete, masonry and stone structures around the world.  

Tecvac Is Now Proud To Introduce

Mira D'OR - Impact Echo Tomography

Data Acquisition and Analysis

This technology reveals unparalleled simplicity and clarity of defects and deficiencies deep inside concrete, masonry and stone members...and puts it right where you can see it.  

Developed from extensive research conducted at the Fedral Institute for Materials Research and Testing (BAM), MIRA D’OR is destined to inaugurate a revolutionary standard for non-destructive testing around the globe.  To discuss your problems...and our solutions, give us a call.
