Concrete Contractor in Diamond Bar - Driveways and Walls Built for Sloped Lots

Diamond Bar is a hillside city, and most of the concrete work we're asked to do here has a slope in it somewhere, whether it's a driveway climbing to the garage, a backyard cut into the hill or a run of steps up from the street. Water from the roof and the sprinklers always heads downhill, and if a slab falls toward the house or the dirt under it was only raked level, that water gets underneath and slowly washes out the support. Before we pour anything here, I look at where the water runs now and where it will run once the new concrete is in, and our crew digs out and packs the base so the slab sits on firm ground instead of settling with loose soil.

Many houses here have been standing a few decades, and their original driveways and patios are at the age where they crack, sink at a corner or hold puddles. When we replace one, the money goes first into the base and the drainage, which you won't see once the pour is done, and only then into the finish. If a budget has to be trimmed, I'd rather simplify the surface than skimp on the base, because a plain slab on solid ground holds up far better than a decorative one on loose dirt.

Building permits here come from the city's Building and Safety Division, which issues them for building, changing, removing or repairing structures anywhere in Diamond Bar. On larger projects, the Planning Division has to review and approve the plans before they can go in for plan check, the city's review of whether the plans meet code, so a job that needs both takes longer to get started than a simple replacement. When your job needs a permit, we handle the application and the inspections, and I'll tell you at the estimate whether I expect one. The city also requires a business license of every contractor working inside city limits, even one based in another city, so it's fair to ask anyone you're considering about theirs before you sign. We're licensed and insured.

Many streets here are steep or end in cul-de-sacs, so how close a concrete truck can park often decides whether we pour straight from the truck or pump the concrete up the hill, and that's one of the things that moves the price. The rest is mostly the size of the area, whether old concrete has to be broken out and hauled away, how much base work the ground needs and the finish you choose, while the schedule turns on any permit, the tear-out and curing, the days new concrete needs before it can carry weight. Your written estimate spells out what's included for your own job. We come over from Glendora, and our crew works the same way next door in San Dimas and Pomona, and farther west in Arcadia.

Diamond Bar is mostly a city of homes, spread across rolling hills, with neighborhoods that wind up and around canyons and back onto open space and the city's unpaved trails. The houses we work on tend to sit on graded lots, with the driveway on one level, the house on another and the backyard stepped down or cut back into the hill, held in place by retaining walls and connected by steps.

Compared with the flatter streets in West Covina, a job here usually means more grading, more attention to where water runs and more walls and steps, so the ground decides much of the plan before we ever talk about finishes.
