Concrete Contractor in Rialto - Driveways and Patios Built on Solid Ground

Common questions

• Do I need a city permit to pour a concrete patio in Rialto?

  Patios are on the list of work the Rialto Building Department issues permits for, so I plan on one for a patio and confirm the details with the city before we schedule. Retaining walls and pools are on that list too, and if your project reaches into the street or the city's right of way, the Engineering Department handles that part. Driveways aren't named on the list, which doesn't settle the question either way, so I ask about those as well and tell you what I learned at the estimate.

• When does a concrete contractor need a California state license?

  A contractor needs a license from the Contractors State License Board to build or alter a structure whenever the project needs a building permit or uses employee labor, or when the contracts on it total $1,000 or more in labor and materials. The board lists some exemptions, such as qualifying owner-builders. A full driveway or patio is usually well past that $1,000 mark, so it's worth asking before you sign anything.

• How much does a new concrete driveway cost in Rialto?

  Your price comes from what I find at the visit, and the biggest swing is usually the ground, because a yard that needs more digging, packing or drainage work costs more before any concrete arrives. A driveway is poured thicker than a patio because it carries cars, and a stamped or colored finish costs more than a plain broom finish, the light brushed texture that keeps a slab from getting slick. If the budget needs trimming, I'd rather you choose a simpler finish than a thinner base, because the base is what keeps the slab from cracking and sinking later.

• What causes concrete patios and driveways to crack in Rialto?

  Most cracks come from ground that was never properly dug out and packed, water running under or toward the slab, and joints that were cut too late or skipped. Concrete shrinks as it hardens and will crack somewhere, so we cut control joints, straight grooves that give those cracks a chosen place to form, and we slope every slab so water runs away from your house. I can't promise a slab won't crack, but this is how we keep cracks small and where we planned them.

• How long does it take before I can drive on a new concrete driveway?

  You can walk on a new driveway well before you can drive on it, because concrete keeps gaining strength for days after the pour while it cures, the wait while it hardens enough to carry weight. Driving on it too early is one of the quickest ways to crack a new slab, so I give you the walking and driving days for your slab at the estimate and again at the walk-through. If a permit is needed, the city's review comes before any of this, as the steps above describe.

• Is Rialto on an earthquake fault, and does that change how a slab is poured?

  The city's own building code findings say two earthquake fault systems, the San Jacinto and the Rialto-Colton, lie within Rialto's limits, though that finding covers the whole city and doesn't map any single lot. For a driveway or patio, the work that matters is the same packed base and control joints, plus rebar, the steel bars inside a slab that hold the pieces together if it cracks. Foundations and footings are built to the code and the plans the city approves.
