Selection – What is the condition of the existing surface? What environmental and traffic conditions will the overlay be exposed to? What maintenance is required? What is the desired look?Ģ.ĝesign Development – Sufficient thickness, sufficient protection.ģ.Ĝolors – Many systems are available in dozens of standard colors and those colors can generally be mixed to create custom colors.Ĥ. To specify a concrete overlay system, a step-by-step process will ensure success. The Specification of Concrete Overlay Systems And the overlaid concrete surface is unaffected by radiant floor heating. Fire resistant materials keep toxins from being release in case of fires. It provided an ambient glow anywhere that is desired, and makes areas safer, helping preventing tripping and falling.įire Resistance. It glows for up to 12 hours, in some cases eliminating the need for electrical lighting. The light-storing material is applied up to 1/8 inch and is charged by natural sunlight. At least one manufacturer offers a glow-in-the dark concrete overlay. Color selection can enhance visibility and decrease lighting requirements. It improves areas where people congregate, such as schools, play areas and parking lots, making them more comfortable.īetter Nighttime Visibility. Can significantly improve the look and feel of any space. This may help you achieve LEED credits under the recycled content category of Materials and Resources. Plus, pigments may be made from up to 99 percent recycled material. An overlay system can incorporate recycled glass, bottles, and other types of post-consumer recycled content. Note that overlay systems are comprised mainly of local sand, cement and water. And overlaid and sealed concrete does not harbor allergens or dust mites. Sealers provide simple cleaning and maintenance, further reducing the need for labor and products far into the life of the product. Concrete overlay systems produce low to no volatile organic compounds. On the contrary, light color selections allow solar energy to be reflected rather than absorbed, keeping the concrete cooler. Darker colors (including black asphalt and dark-colored pavements) absorb more heat, raise pollution levels and increase need for air conditioning or cooling methods. When it’s all said and done, properly applied concrete overlay system extends the life of concrete structures and slabs.Īnd, the process can help you qualify for LEED points in these areas: Here are some basic costs for concrete resurfacing products:Īs these charts indicate, the cost to resurface is less than the cost just to remove the existing concrete, let alone replace it with a new concrete slab. Job related costs of specialty equipment used for job quality and efficiency, including: 115v, 15-amp electric jackhammer, 1000+ blows/minute.Ĭost for Basic Decorative Concrete Resurfacing with Sealer/Protection Cost to Remove Concrete SlabĪccording to one company that removes concrete slabs, here is a possible cost breakdown iiĭirect labor expenses to remove concrete slab: 10.3 hoursĬosts to load and haul away old materials and installation waste This is one of the truest examples of having a small footprint, or of sustainability. Improving what’s already there requires minimal interference with existing vegetation. That means no special heavy equipment hauling materials across town or across the country, both to remove the demoed material and to bring in the new materials. There is minimum site disturbance and earthwork required. This goes for concrete as well.Ī concrete overlay system reduces the need for more key resources such as concrete, steel and rebar, and makes best use of what is already there. As green building proponents like to say, the greenest building is the one that’s already built. Not only is demolition and replacement expensive and disruptive, it’s also the option with the greatest embodied energy. The most obvious benefit is diverting demoed concrete from landfills.
Green Attributes of Concrete Overlay SystemsĬoncrete overlay systems provide enormous green attributes when compared to the process of concrete removal and replacement.
