The best way to get stamped concrete over existing concrete is a stampable overlay. If the underlying concrete is not structurally sound, it is not worthwhile to overlay it. Surface deterioration and loose materials on the surface will prevent the overlay from adhering. Major cracking and shifting will cause the concrete overlay to break and crack, too. Examples of significant damage include large cracks, settling, and massive surface deterioration. Any significant structural damage will cause problems later on. In this case the subgrade is the existing concrete slab!įirst, carefully inspect the concrete for damage. As with new placement, the slab is only as good as the subgrade.

Heavy equipment and trucks can crack adjacent concrete. Skid steers and earthmovers will destroy landscaping and grass. On top of the added labor and cost, demolishing existing concrete has the potential to damage surrounding areas. All of this adds thousands of dollars and hours of labor before the new slab is even started. There is also additional labor and cost associated with disposal and demolition equipment rental. Replacing concrete can be traumatic! Demolishing and removing reinforced concrete can take several hours for just a couple hundred square feet.

Color stamp concrete using any combination of integral colors, color hardeners, and stains. This creates permanent patterns and textures in the concrete. While it is still plastic, concrete is imprinted using these tools. Stamped concrete is created using specialized texturing tools. Stamped colored concrete is a premium flooring and paving option with a wide range of benefits that make it a desirable alternative to pavers, standard concrete, and stone. It is also more economical and durable than many of its natural material competitors.
