CONCRETE RESTORATION SYSTEMS
Pages 9-11 provide an award-winning CRS project reference. The renovation of the high-traffic flooring at the Canadian Science and Technology Museum in Ontario was such a success that it won the award for Public Buildings and Urban Design in MAPEI’s internal International Reference Projects Grand Prix. But the CRS line provides more than the concrete repair products used in this project. Interacting with state Departments of Transportation (DOTs) and facility managers alike, this product line spans a full spectrum of solutions – from bridges to stadiums to public facilities like museums. This line also offers coatings and sealers, decorative toppings, waterproofing systems, structural strengthening
systems, and admixtures for concrete among other product solutions.
WATERPROOFING SYSTEMS
MAPEI offers a wide variety of waterproofing systems including bentonite clay membranes and self-adhering sheet membranes. The newest addition to its waterproofing product line is an exciting one: Planiseal® CR1 cold-fluid-applied waterproofing membrane. Fast-curing, single component and 100%-solids, this membrane is applied like a coating and contains virtually no VOCs. This means that, unlike many waterproofing systems, Planiseal CR1 can be applied in and around occupied spaces.
PRODUCTS FOR STRUCTURAL STRENGTHENING
In addition to the Elastocolor ® coatings line that was featured in Realtà MAPEI North America (Issue 29) as lending customized aesthetic beauty to the famed Philadelphia Metropolitan Opera House, MAPEI’s Products for Structural Strengthening line offers several products to provide varying degrees of structural strength. There are epoxy adhesives, concrete repair mortars, laminate wraps, glass fiber wraps and carbon fiber wraps – all of which can be custom-engineered by MAPEI to meet specific job requirements. For example, MAPEI’s fiber-reinforced polymer (FRP) products were specified in combination with CRS products to preserve the substantially corroded JEA Northside Generating Station bridge in Jacksonville, FL.
ADMIXTURES FOR CONCRETE
MAPEI’s admixtures line offers industry-leading products including water reducers, retarders, accelerators, superplasticizers, shrinkage reducers, corrosion inhibitors, viscosity-modifying agents, fiber reinforcement and air-entraining agents. When added to concrete, these products play vital roles in accelerating/decreasing curing rates and strengthening the concrete. They are the crucial “secret ingredients” hidden in the midst of the final built results. Examples of projects featuring MAPEI’s concrete admixtures? How about U.S. Bank Stadium (the home of the Minnesota Vikings), the concrete bases of a large wind-generation farm in Texas, and a tunnel and runway at Missouri’s Lambert Airport, to name a few.
