Concrete
Sunken, lifted and broken sidewalks, curbs, walkways and parking stalls, including ADA stalls, replaced after we deal with whatever moved them.
In brief
Concrete repair replaces sunken, cracked or lifted panels after dealing with what moved them: tree roots, settlement, poor subgrade, missing joints or water under the slab. Panels are sawcut to joint lines and set flush with drainage fall maintained. Small lips on sound slabs can sometimes be ground down. In many Bay Area cities the owner is responsible for the sidewalk along the frontage.
01
The cause decides the right repair. These are the conditions we see most on commercial sidewalks, walkways, curbs and stalls.
On an accessible route, the tolerance is very small. Under the 2010 ADA Standards, a change in level of up to 1/4 inch can be vertical, and up to 1/2 inch if beveled. Anything larger has to be ramped or removed, so even a lip most people step over can need attention.
A panel that dropped will drop again if the ground or water path beneath it isn't fixed, so we find out why before we replace it.
02
Small lips on sound, stable concrete can often be ground down. Holes and broken edges can be patched where the surrounding concrete is sound. Panels that are broken, badly settled, lifted by roots or already patched once should be replaced. Main entrances and accessible paths of travel are where a it's worth doing the repair right.
03
Whether it's one sidewalk panel, a parking stall or a run of curb and gutter, the steps are the same.
04
Many Bay Area cities make the adjacent property owner responsible for the sidewalk along their frontage, and some send repair notices after an inspection or complaint. Work in the public right-of-way needs a city permit and has to be built to the city's standard. Rules vary, so check with your public works department; if you've received a notice, talk to us. Permit fees are not included in our proposals, but we work with you to obtain the permit and can help with drawings.
Grouping repairs into one project usually costs less rather than calling a contractor out for each panel.

Questions
Sometimes, for small level differences on a sound slab. Where the panel has cracked or settled, or whatever moved it is still at work, the lip comes back.
In many Bay Area cities, the adjacent property owner is, even though the sidewalk is in the public right-of-way. Confirm with your city's public works department.
It can, if the roots are left as they were. A good repair deals with the roots as well as the concrete.
Grinding reopens almost immediately. Replaced concrete needs to cure, and foot traffic usually returns well before vehicles. We can phase repairs so entrances stay open.
New concrete is lighter at first and tones in over time. Cutting to the existing joint lines keeps the repair looking clean rather than patched.
