The Backstory - 

Back in 1998, the Environmental Protection Agency "legislated" it's way clear of all the high Volatile Organic Compounds (VOCs) in all paints, sealants, coatings, and ADHESIVES.  The days when your choice of adhesives were in the 10,000s parts per million of VOCs are gone. Today, adhesives are up to 50% water and contain only 100-300 parts per million of VOCs. The least bit of moisture, in the form of vapor or mist (think of water passing through a semi-permeable object) moves up from either the sub-base (mother earth) and/or from within the concrete itself (17 gallons plus per cubic yard of "extra mix" water) to the surface and "re-wets" the adhesive.  The damage is seen in blisters, bubbles, ripples, delaminations, etc. in the flooring and is responsible for over a billion dollars each year in failures.  That same moisture/ vapor feeds the growth of mold and bacteria, destroys indoor air quality and corrodes every circut board (computers!) in the environment.

Logik MVRA 900 is a liquid sodium silicate hydroxide containing various Nano-Silicas that work with the cement and "extra" mix water to produce additonal calcium silicate hydrate (C-S-H) that floods the cement matrix and virtually eliminates the capillary system so detrimental to concrete.  The chemical formula for cement hydration (tricalcium silicate + water - 50% of total cement hydration) is below -


2 Ca3SiO5 + 7 H2O ---> 3 CaO.2SiO2.4H2O + 3 Ca(OH)2 + 173.6kJ


As you can see from the chemical equation above, water is always present within the concrete.  Our concern is not the presence of that moisture, but the movement of that moisture to the surface of the concrete.


Logik MVRA 900 is sold through the commercial ready-mix concrete producers and is a critical material listed on the certified "Batch Ticket".  Logik MVRA 900 is dosed in the beginning of the mixing process (goes in with the head waters)  and is added according to the amount of cement and fly ash in your mix - an automatic process of protection that can't be misplaced or mis-installed.

The Logik MVRA 900 technology is truly legitimate and can be seen in the results of millions of square feet of beautiful flooring adhered to Logik MVRA 900 enhanced concrete throughout North America - with hundreds of thousands of square feet here in Southern California.  Every kind of expensive moisture "in-sensitive" flooring has been adhered to Logik MVRA 900 Concrete flawlessly with a two-tiered Lifetime of the Concrete WARRANTY - for both moisture/vapor emissions and adhesion!

We have every kind of flooring and coating imaginable installed over Logik MVRA 900 enhanced concrete - in perfect service to date.....and we'd love to share the results with you.  Logik MVRA 900 can be budgeted at the eleven cents ($0.11) a sqaure foot, per inch of concrete thickness, installed, range.
