![]() Due to the large initial cost of constructing these relatively thick layers (which includes costs associated with raising of the shoulders, bridges, and intersections), there is interest in understanding the performance of thinner unbonded concrete overlays. Design thicknesses for these overlays tend to be greater than 7 inches. The research on this cell will be done as part of a Multi-state Pooled Fund project TPF-5(165) that will use the MnROAD and other test section data to develop a rational design method for thin concrete overlays.Ĭurrent pavement design methods treat unbonded overlays similar to concrete pavements lying on traditional aggregate base layers. A new thin whitetopping section built on a full depth bituminous cell in poor condition will be constructed to create a test section to help to answer these questions as well as add to the performance database from which a rational design method for whitetopping will be developed. Researchers and pavement designers still question if the data from these test sections can adequately represent the performance of whitetopping on asphalt pavements that show distress (cracking, rutting). However, the underlying HMA pavements were in good condition and did not represent typical conditions. Some whitetopping cells have been built previously at MnROAD. Whitetopping and unbonded concrete overlays have great potential as pavement rehabilitation methods. Find a local contractor.Performance of Thin Unbonded Concrete on High Volume Roadsĭue to increased traffic congestion and reduced highway construction budgets, emphasis is now being placed on seeking effective rehabilitation techniques for older pavements. Our professional contractors can do it for you. It also enhances its stain resistance and makes it easier to maintain. A sealer will preserve the look of your concrete surface for longer. Customers often ask us if outdoor concrete needs to be sealed, and our answer is always yes. After the overlay cures, add a sealer for additional protection. This is completed using hand-trowels, rakes, stamps and other specialty tools. Depending on the desired look, apply the overlay by spraying, rolling, or troweling. Following instructions, mix the product to prepare it for application. Clean with a pressure washer and let surface thoroughly dry. Etch, grind, or shot blast the concrete surface to make it porous. Here’s an overview of the installation process (details vary depending on which products are used): SUNDEK contractors are trained in proper mix ratios and installation procedures to ensure our coatings last. With good surface preparation, proper concrete coating application, a protective sealer and routine maintenance, we’ve seen jobs that look just as good 10 and even 20+ years later. When done properly, resurfaced concrete will last a long time. Contact your local SUNDEK contractor to get a quote. Your project’s cost will also depend on the condition of your existing surface. The cost of concrete resurfacing varies depending on where you live. See our products to get an idea of the design options available, or talk to a local SUNDEK authorized contractor to get ideas. Did you see a picture in a magazine of a pool deck you love that was created using knockdown texture? Show us, and we’ll figure out how to create that same look. ![]() ![]() If you love the look of the neighbor's concrete driveway down the street, we can replicate it. If you have a new patio and an outdated walkway, we can design your walkway to match or coordinate with your patio. Some of our most popular choices are textured spray coatings, stamped concrete overlays, and thin, smooth microtoppings. This includes the ability to make concrete look like stone, tile or brick. ![]() The variety of concrete resurfacing options available through SUNDEK means you can get the exact color, texture, pattern, and style you want for your outdoor space. ![]()
