The quantification of traffic over the design life of the floor is required for all thickness design procedures. In addition to the surface evaluation of the existing floor slab, the degree of support beneath the floor surface layers should also be evaluated. Curing is recommended for all overlay projects. The overlay will vary according to flooring conditions.Ī common method for floor surface evaluation is deflection testing, particularly with the falling weight deflectometer. For example, if it is for floors that are exposed to heavy foot traffic and extreme conditions you will need durable overlays that are built to withstand wear and tear. While deciding on the concrete overlay, it is important to analyse what type of conditions your flooring will face.

Here are a few factors that should be kept in mind before the execution of concrete overlay. One must look for overlay blends that are strong and made out of high-quality ingredients such as polymer resins, a mix of cement and sand, and other additives.

They are placed on top of the existing concrete pavement and ensure a full bond between new and old concrete layers. Bonded overlays become part of the underlying existing floor slab. Concrete overlays can be applied as thin as a feather finish depending on the desired finish.Īll concrete overlay types fall into two divisions- the bonded and the unbonded. There are different blends of portland cement, different aggregates and polymer resins with polymer-modified additives in each product. Depending on the manufacturer, the overlay products vary in the mixture and proprietary blends. A well-designed and constructed concrete overlay floor provides excellent performance, in many cases extending the life of the floor surface for years. It could be colored or cementitious based.
