Shown below are examples of Holliday Concrete's residential flatwork. Completed jobs of satisfied customers including driveways, patios, steps and stoops. All concrete shown is a minimum of 4000 PSI with rebar reinforcement. All our flatwork is poured on a prepared 3" to 6" base. The base consists of compacted rock, sand and gravel for a stable foundation. We use our custom designed mix for durability and strength. Our class A rock mix is a much harder and stronger aggregate than conventional limestone and is far less likely to crack. The chance of flaking and spalding is also greatly reduced.
