Why Norco homeowners redo their concrete

Most of the calls we get start with something you can see, like a driveway cracked across, a patio that's sunk and holds water, or a walk lifted at a joint. The cause is usually underneath. Either the base was raked level instead of dug out and packed, or the slab falls toward the house so water runs the wrong way.

Price moves with the size of the area, how much old concrete comes out, how much digging and base the ground needs, and the finish. A plain broom finish, the light texture that keeps it from getting slick, costs less than decorative concrete. The schedule turns on any permit, the weather and curing, the days a new slab needs before it takes weight. Your written estimate spells out what's included.

If the budget's tight, I'll tell you to cut the finish before the base. Nobody sees the base on day one, but it decides whether the slab settles and cracks, and a plain slab on good prep outlasts a fancy one on loose dirt.

What we check before pouring in Norco

The city's own findings say thin alluvial soils, the sand and silt laid down by water, give parts of Norco a moderately high chance of liquefaction, which is ground that can go soft in a hard quake. The Chino fault also sits just inside the city's southwest edge. So I start with the subgrade, the dirt the slab sits on, and we dig out soft spots and pack the base rather than rake it smooth.

Then I check where the water goes. A slab should shed water away from your house, so I look at how the yard drains, where the downspouts empty and where new concrete has to meet an old walk or garage floor. We pour early so the midday heat doesn't leave a weak, dusty top.

Questions Norco homeowners ask us

Do I need a permit for a concrete driveway in Norco?

Ask the city to be sure. Norco's Building & Safety department issues permits for new buildings and for altering or enlarging existing ones, and that list doesn't name driveways or patios. If your job needs one, I'll go over it with you at the estimate.

Does a short concrete retaining wall in Norco need a permit?

Under the city's proposed code, a retaining wall no more than two feet high doesn't need a building permit. That height is measured from the top of the footing to the top of the wall. The exemption doesn't cover taller walls or walls holding back a load beyond level ground, such as a driveway above, so I check those with the city first.

When does a concrete contractor need a California license?

The Contractors State License Board requires a license for anyone building or altering a structure when the job needs a building permit, uses employees, or totals $1,000 or more in labor and materials. A bigger job can't be split into pieces under $1,000 to get around that. Norco also requires a city business license before anyone works in the city.

Will my new concrete driveway crack like the old one?

It can still crack, but we decide where by cutting control joints, which are shallow grooves that give the slab a planned line to break along, before it cracks on its own. The bigger fix is underneath, in the packed base and the drainage I check first. Where the slab needs it, we add rebar, steel bars that hold the pieces tight if a crack opens.

Does a High fire hazard zone in Norco affect my concrete project?

It can. The city says homes in High and Very High fire hazard zones must meet home hardening requirements, and new construction and renovations there follow the wildland-urban interface building codes. In a Very High zone, you also have to keep 100 feet of defensible space, cleared ground, around structures. I'll check which zone your house is in before we plan the job.
