Install Precast Concrete Steps . Precast concrete steps can be faced with brick and come with either 7 or 7.5 inch risers can be “stacked” in unlimited combinations and placed side by side if a wider tread be desired. Repeat this process until you reach your destination. Precast Concrete Steps for Any Application • Reading Precast from www.readingprecast.com When they cross the pvc pipes, get the steps and put them back in front. The price of precast steps depends on the material and riser. Small concrete pads are set under each side of the steps toward the front of the unit.
