All sidewalk placed by Black Rock Construction meet or exceeds the guidelines and recommendations of ACI (American Concrete Institute). There are many different finishes. Sidewalk types our company is familiar with and experienced with placing include broom finish, salt finish and retardant finish. It is usually recommended that walks be placed on a 4″ sand base. Although a sand base is recommended, if a good soil base is present it may be used. In most cases our company will provide preparation of the subgrade. In situations that allow it, we can slipform sidewalk in widths up to 4′. We can build new molds for various sizes In the situations were the walk is machineable, it can be placed at a very fast pace, up to 2000 linear feet per day.
