Ken Arnott, owner of Kenbar Floors who recently completed approximately 7,000m2 of flooring installation at the Forest Lodge Nursing Home, built by Aged Care Developments, said “I am delighted with the finished job and the way the synergy of all suppliers, concreter, builder and owner helped achieve a cost efficient, fast track, trouble free, safe, very functional and aesthetically stunning result for the client and all concerned.
When we started, the initial 3000m2 of concrete had been poured and the building process was at lock up stage. We were confronted with high moisture readings (6.5%) in the concrete, as is common with so many projects these days and flooring contractors are faced with dealing with concrete slabs that the moisture readings are in excess of the 5.5%, 70 RH as recommended by the Australian Standards. These high readings mainly occur because of the fast track lock up building process, which doesn’t allow enough time or air flow movement to sufficiently dry the concrete to meet the required moisture content levels for correct floor covering installation, at no risk of costly failure to the Installer, builder of Client.
We opted to use the Oxtek X220 Moisture-Fix & X200 Densi-Proof products because of the cost efficiency, VOC free, user safe, simple no mixing one coat application and early access benefits, as well as the total performance warranty aspects of the product. We installed Polyflor vinyl in all of the main areas and also used the Polyflor range of floor levelling cement and adhesive range of products as well. Polyflor offer a total warranty covering the whole system from the top of the concrete substrate to and including their vinyl as a guaranteed system including the Protect Crete products. This is excellent for the Installer and client as there isn’t room for any demarcation problems should an issue occur.”
After discussions with the Builder and Concreter (Rypcard Concreting) and Terry Lucas from Oxtek, it was decided to apply Oxtek X200 Densi-Proof at the time of pour. Terry explained “This allows a superior cure medium, densifier and permanent moisture barrier that allows for coatings and floor coverings to be installed without any moisture issues after 14 days after pouring of concrete. This also saves costs, as there are no preparation costs and virtually eliminates any plastic cracking in the slab. They have proceeded with this process and every one was absolutely delighted with the concrete surface finish and the amount of time and cost savings with this process.
Every one is delighted with the whole project, an excellent on time result.
X220 Moisture Fix® applied at time of pour. Used as a curing compound, waterproofer, densifier and hardener. Concrete is permanently waterproofed.
Epoxy paint system & vinyl will not require acid etching or mechanical abrasion before application.
This was the comment from Peter Rawlins; construction site manager working for builders Aged Care Developments, when he was describing improvement in slab qualities and ultimate cost savings gained after Oxtek products X200 Densi-Proof/ X220 Moisture-Fix was applied to his concrete at the time of pour as a superior curing medium.
As reported in the October issue of Flooring Magazine Peter used Oxtek products on the Forest Lodge Nursing Home in Frankston North that was built for TLC Aged Care Nursing Homes. “I just couldn’t believe the difference in the concrete surface integrity, hardness, lack of plastic shrinkage cracking, dust proofing without changing the surface profile. We saved on the application of so called lower cost curing membranes, plus the removal costs down the track of the same, and also, if the topical membrane had performed properly, in reducing the evaporation of the excess water (which normally creates problems with plastic or premature shrinkage cracking) which is used in the mix design that isn’t required for correct cement hydration for strength gain. Of course the concrete would always remain reading too wet to meet the required standard of moisture content percentage for successful coatings or covering installation.
In this case, then the lower priced membrane has to be removed by mechanical means, such as grinding, shot blasting etc. which also adds to the cost. After the success at Forest Lodge we are currently constructing Noble Manor Nursing Home and using X200 Densi-Proof as soon as possible after concrete placement and it is clearly apparent that the enhancement of concrete quality, savings of preparation costs down the track alleviating the need for removal of inferior membranes and site disruption of the same to meet the moisture content levels required by the Australian Standards.
Applying at the time of pour is then really the most efficient and cost effective option.The Oxtek products absolutely help us to meet the demands and pressures of fast track building lock up and finish dates, where the concrete just doesn’t have time to dry sufficiently. It is a one off application and even though it can be applied to concrete at any stage to overcome moisture related problems, we now use Oxtek as an integral part of all our building process at the time of pour which not only enhances our concrete performance, it allows floor covering installation to proceed at any time without problems.
When Ken Arnott of Kenbar Floors first suggested the Oxtek products can be applied sooner than later, I must admit that initially I wasn’t entirely convinced, however we proceeded with our own trials, same concrete mix design, same concreting contractor, same conditions and the results between the concrete with and without the Oxtek applied, was almost unbelievable. We have also done our sums and the cost and time savings are very significant indeed. I am also very impressed that there is no site closure due to safety issues as the products are totally VOC free and the floor access is open within one hour after application. Of course we realise that we not only have all these improvements with the concrete but we acknowledge the fact we have an effective, permanent and guaranteed moisture barrier under all our floor coverings.”
