Frequently Asked Questions

1. WHAT IS THE PRIMARY CHEMICAL COMPOSITION OF YOUR PRODUCT?

The primary component in Concure Systems Admixture is silicate. The admixture reacts with the properties in the concrete creating a gel, densifying the concrete.

2. WILL IT, OR COULD IT, REACT WITH ANY OTHER CONCRETE ADMIXTURES? 
No negative reaction with other admixtures. It is compatible.

3. DOES IT CHANGE THE COLOR OF THE CONCRETE?
The color of the concrete does not change but is more consistent. The Admixture eliminates most of the mottling.


4. DOES IT CHANGE THE FINISH OF THE CONCRETE? 
The finish is smoother, denser, and in most cases eliminates the need for other topically applied sealers.


5. DOES IT REACT WITH STEEL? 
The Admixture encapsulates the steel and rebar, inhibiting rust and corrosion and helps to protect the steel and concrete from corrosive soils.


6. DOES IT CHANGE THE STRUCTURAL VALUES OF THE CONCRETE? IF SO DO YOU HAVE INDEPENDENT TEST RESULTS OR ASTM TEST NUMBERS AND RESULTS?
Concure systems Admixture densifies the concrete, typically increasing strength up to 125%. We have an independent analysis on Concure Systems Admixture as well as an abundance of data from projects over the years and would be happy to share it.


7. IS IT USABLE IN ALL TYPES OF PORTLAND CEMENT CONCRETE?
It can be used in all cement types and cementitious including stucco & shotcrete.


8. CAN THE CONCRETE SURFACE BE PAINTED JUST LIKE CONCRETE WITHOUT ADMIXTURE? 
Yes.


9. IS THERE A COMPATIBILTY ISSUE WITH COLORED CURING COMPOUND AND CONCURE? 
No, they are compatible.


10. CAN SLABS ALSO BE CURED WITH PLASTIC MEMBRANE OVERTOP? 
Yes, Concure Systems follows ACI and Resilient Flooring Institute guidelines for curing interior slabs to receive flooring. (See Concure Systems 2100 Cure & Seal alternative which promotes bond and does NOT require removal)


11. MUST YOUR CURING PRODUCT BE USED (CONCURE SYSTEMS 2100)? 
The 2100 was developed only to take the place of other curing compounds and sealers that require mechanical removal and surface reprofiling and are not compatible with all flooring adhesives and coatings. The 2100 actually enhances the bond between adhesives and coatings, does not require removal and gives the GC full access for all trades (except flooring installation) the next day.


12. HAS THE PRODUCT BEEN APPROVED OR ENDORSED BY ANY MAJOR FLOORING MANUFACTURER?
No flooring manufacturer will endorse a manufacturer of moisture vapor emission control systems as it lends to libel but we have worked with the majority of flooring manufacturers over the past 26+ years with great success.


13. HAVE YOU HAD ANY FAILURES? 
We have had no failures in 26 + years.


14. DO YOU HAVE ANY REFERENCES AND MAY I CONTACT THEM?
We will be more than happy to forward our reference list to you. Yes, by all means please contact anyone who has used our superior product!


15. WOULD IT BE DIFFICULT TO ACCOMMODATE YOUR PRODUCT INTO SPECIFICATIONS? 
The Concure Systems Admixture, Vapor Barrier +PLUS+ (topical), 2100 Cure & Seal & Crack Fill Binder can easily be integrated into your 03300 specs. Ask us for CSI specs.


16. DOES YOUR WARRANTY INCLUDE REPAIR OR REPLACEMENT OF ANY DAMAGE CAUSED BY FAILURE OF YOUR PRODUCT?
Our warranty clearly states that we do replace/repair any damaged flooring from moisture migration through the slab. We will gladly forward a copy of the warranty to you.


17. HOW LONG DOES IT TAKE TO CURE OR BE SUITABLE FOR MOISTURE TESTING OR FLOOR INSTALLATION? 
We subscribe to ACI guidelines for cure time, 28 days minimum. There is very little bleed water or hydration with Concure Systems Admixture. In most cases flooring can be installed 30 to 45 days after concrete placement. Per ACI/RFCI recommendations a .45 water/cement (w/c) ratio is recommended. See data sheet for recommended w/c ratio, slump, and dispensing requirements.


18. IS YOUR PRODUCT APPROVED BY DSA AND OSHPD? 
There are no admixtures approved by DSA or OSHPD. In January of 2002 DSA re-evaluated their program and no longer includes admixtures.
