This concrete entrance way had a very big area delaminating. Before we begin to repair the concrete we have to check to see if there are any hollow spots in the concrete. We check by banging a hammer or running chains over the surface of the concrete. This concrete had a lot of hollow spots that were chiseled out.
You can notice in the picture above the edges are cut 90 degrees, this is because you do not want the repair mortar to be feathered out at the edges.
After the concrete has been resurface you apply a concrete stain to add color to the newly refinished concrete.
