From Realtà Mapei n° 35 - 8/12/2022
Whether your concrete floor needs a single cavity filled or a major concrete restoration, you can choose from a variety of MAPEI concrete repair products to meet the needs of your specific job. Contractors might appreciate the ease of use and extended working time afforded by Topcem Pronto. Concrete restoration experts will be impressed with Mapecem 202’s fast setting time for external applications needing a corrosion inhibitor, or the shrinkage-compensated flowability of Planitop 25.
Pumpable, flowable concrete repair mortars are a long-time specialty of ours. Concrete restoration professionals needing a deep-fill pour for large repairs may want to use Planitop FD for example, or the pre-extended Planitop 11. If you’re looking for a form-and-pour mortar with corrosion inhibitor, Planitop 11 SCC is also self-consolidating, which is good for full-depth structural concrete repairs in above-, below- and on-grade applications and cavities that contain congested reinforcing steel.
Concrete deterioration doesn’t only happen to horizontal surfaces, of course. MAPEI offers a variety of concrete repair mortars specially formulated for vertical and overhead applications. There is the sulfate-resistant Planitop 12 SR and the machine-applied Planitop Shotcrete for industrial concrete repair applications, among others.
When high-traffic areas need to be repaired with limited downtime, these concrete restoration products provide rapid hardening to get the affected areas back in service or ready for further coverings quicker than others. For example, Planitop 18 is very rapid-hardening, providing compressive strength of > 2,500 psi (17.2 MPa) just an hour after setting, whether neat or extended by aggregate up to 8" (20 cm). And if you need extended working time, Planitop 18 ES is specially formulated for that, while Planitop 18 TG is trowel-grade and extends strength so quickly that areas can be opened to vehicular traffic in as little as two hours, under optimal conditions.
For detailed information on all the above products, including their extensive testing with data on shear strength, be sure to download the respective Technical Data Sheets from www.mapei.com.
A product labeled “low-VOC” or “zero-VOC” does not mean it is safe or good for your health, nor does it mean that it contains no toxic chemicals. VOC content (what’s in the product) doesn’t correlate to VOC emissions (what the product emits). Products with zero or low VOCs can still emit VOCs. To that end, all the above MAPEI products were third-party tested and third-party certified for low VOC content and low VOC emissions, achieving Indoor Advantage Gold certification from SCS Global Services to meet California Department of Public Health (CDPH) Standard Method v1.2-2017.
Concrete restoration is a serious business, and MAPEI takes the formulation and production of its concrete repair products just as seriously. As an ISO 9001-2000 certified company that employs exacting standards to ensure quality and consistency from batch to batch, MAPEI also offers an in-house technical services team that responds to customers’ telephone inquiries in real time and can even offer field support for on-site problem resolution.
