The author decided it was time their home got a facelift. The technique of choice was whitetopping, so they called Dan Mullendore, a local contractor with a track record for high-quality flatwork. He decided their asphalt was good enough to use as a subbase and they had enough elevation to accommodate the extra 3.5 inches of concrete that would be needed. Mullendore determined that the finished drive would have to slope in two directions in order to drain properly, and a swale near the street was needed to direct flow to an underground drain.
A backhoe tore out a section of the old concrete walk adjoining the driveway. A small area of asphalt was also removed to make room for added landscaping. Compacted fill was then put down in low areas to maintain a uniform thickness of the overlaid material. Shrinkage cracks might otherwise start at points where the concrete thickness changed. Forming involved a combination of wood and steel staked into place. Flexible isolation joint material was put in place at construction joints and at points where the whitetopping would abut existing construction. The crew leveled and floated the concrete as quickly as possible, and the surface was given a light broomed finish when the concrete had set just enough to prevent the broom from digging too deep. Mullendore didn't deem it necessary to seal the joints, and his experience without sealing has been satisfactory.
