Foundations and Additions C.R. Cook's Concrete uses Precise Aluminum wall forms for all residential or commercial foundations.  Residential concrete walls are reinforced with three continuous horizontal sticks of rebar.  Pilasters are placed in walls 40 feet or longer as needed for additional support. Footings Residential foundation footings are reinforced with two continuous sticks of rebar and with a continuous keyway to ensure a perfect lock between the footings and the wall. Under Pins If you need a foundation added, replaced or moving a house to a new location, C.R. Cook's Concrete can pour an underpin and make your new foundation a reality.
