Concrete Flatwork

Our Areas Of Expertise

• ADA ramps. Handicap and wheelchair ramps must meet the requirements of the Americans with Disabilities Act (ADA) as to ramp slope and length, landing size and placement, and handrail construction and must also meet local requirements.
• Additions. When you want to expand the footprint of your current space without relocating, RCI can create a new addition that blends with the old building, while not compromising the soundness of the existing structure.
• Curbs and Gutters. A curb is a short concrete wall about 6 inches high that forms a barrier between a yard and the street, while a gutter is a flat concrete slab that abuts the curb and drains water away from the yard. The pose is to separate the road from lawns and sidewalks, structurally support the pavement, and facilitate drainage. They give a finished look to a project. RCI adds curbs and gutters to most projects, especially in urban areas.
• Driveway approaches. Usually sloped to facilitate drainage, driveway approaches transition vehicles from the public street to parking lots, driveways, or large doorways on private property. Local codes dictate a thickness of 6” or more, using concrete with a psi in line with expected traffic.
• Foundations. Depending on your specifications, RCI provides concrete slab, concrete block, T-shaped foundations using footings, and elevated, foundations using posts or pier and beam. After considering usage, size and weight of the building, soil conditions, and budget, we engineer in the qualities you need, such as compressive and tensile strength, earthquake and fire safety, and surface finish.
• Sidewalks. A type of flatwork common to homes and buildings, sidewalks are framed and poured in sections separated by expansion joints to prevent cracking. Sidewalks are often poured without rebar reinforcement. To maximize safety, sidewalks are often treated to prevent slipping and improve grip.
• Slabs. Large, flat expanses of concrete are often needed for the interior and exterior projects. Common uses include:
  • Building slabs. These steel reinforced horizontal slabs, often 4-20” thick, are used for floors and ceilings in buildings. The thickest slab in industrial is usually the ground floor, which may be laid on the foundation or directly on the subsoil for outbuildings.
  • High tolerance floors. Floors in industrial facilities, warehouses and distribution centers may need to bear an optimal load, resist cracking, and maintain the highest degree of flatness and levelness to accommodate lift trucks and other mobile equipment. Steel fibers ensure needed durability.
  • Lightweight slabs. Often measuring 2-6”, thinner lightweight slabs are used for exterior paving or under main floor slabs or in crawl spaces where are sometimes called mud slabs.
  • Elevated composite slabs. Concrete is poured into metal framework (decking) to create an elevated composite slab. With the decking kept in place after concrete is poured, the tray-like structure is strong, long-lasting, and resistant to cracking and disintegration. Elevated composite slabs are used for many commercial, and industrial buildings, hospitals, stadiums, and parking structures.
  • Post-tension slabs. The post-tensioned slabs employ strands for horizontal applications such as beams, foundations, floors, or foundations, and bars for vertical uses for walls or columns.
  • Parking lot slabs. Offering a long lifespan and modest upkeep costs, especially in warm climates like Southern California, concrete parking lots are less expensive than asphalt - especially given the high price of liquid asphalt. Poured over a soil subgrade and gravel base to distribute the weight of traffic, a concrete parking lot is often installed at shopping malls, convention centers, restaurants, convenience stores, industrial facilities, and apartment complexes,
