Concrete sidewalk building in Monrovia CA - a walk that drains right and holds up

Most people call when the old walk has cracked, gone uneven, sunk in spots or started holding water after the sprinklers run. The price mostly moves with the walk's length and width, whether there's old concrete to break out and haul away, how much digging the base needs and whether part of it has to carry cars. The schedule turns on whether your walk needs a permit and on the curing wait after the pour, and your own number comes from the estimate, where I measure the walk and write down what's included, like removal and hauling. We check with the city or county office that covers your address before we set a date, and if the walk ties into a worn-out driveway, we can talk about concrete driveway building on the same visit.

I start by asking where cars will cross the walk, because that stretch has to be built for the weight from the start, not patched later. Then we check where water runs so the finished walk sheds it away from the house, break out and haul off any old concrete, and dig down to the subgrade, the soil the slab sits on. We backfill and pack the base instead of raking it level, since a raked base settles with the dirt and takes the walk down with it. We set the forms, pour, give the top a broom finish, a light brushed texture that keeps it from getting slick when it's wet, and cut control joints, the grooves that give the slab a planned place to crack. After the pour we keep the new concrete wet and covered while it cures, the slow hardening that decides how strong the walk ends up. If the budget's tight, I'll keep the finish plain before I'll cut corners on the base, because the base is buried on day one and it's the part that decides whether the walk stays put.

A walk usually leads somewhere. If it ends at a garage with a cracked or sinking slab, we can plan garage floor concrete alongside it so the two meet at the same height and drain the same way. If you want more than plain gray, decorative concrete adds color or a pattern without changing the base work underneath.

A sidewalk in any Monrovia street needs a city construction permit, whether it's new or rebuilt, and Monrovia Public Works issues and inspects those permits. Public Works takes applications in the order they come in and review can take up to two weeks, so whoever pulls the permit should apply early to keep the pour date. Street-side work also has to follow the city's mandatory street construction standards. The city wants a contractor working under its Encroachment Permit to hold a California Class A General Engineering license, and without one a C12 Earthwork and Paving license is typically required, though other license types may be accepted. The state adds its own rule, which says a job needs a state contractor's license if it needs a building permit, uses other workers or costs $1,000 or more in labor and materials. If your walk needs a permit, we sort out who pulls it and get it in hand before work starts.

Clay is the other thing we plan for. A homeowner guide from a California geotechnical association says clay soil swells as it soaks up rain or sprinkler water, with enough force to crack concrete, so before we pour we look at where the sprinkler heads spray and where the walk runs along planted beds. We're based in Monrovia and work across the San Gabriel Valley, and we plan around sprinkler lines the same way on walks in Arcadia and Pasadena.
