Sidewalk Repair

Sidewalk path leading to a home.

You’ve heard the saying “Step on a crack, break your mother’s back.” Well, when your concrete sidewalks are cracked and uneven, they can actually become a real safety hazard.

But don’t worry, sidewalks can be fixed—and Bay Area Underpinning has a leading solution. Since 2005, we’ve been helping homeowners in Northern California repair their concrete.

What is Sidewalk Repair?

Before (left) and after (right) sidewalk repair.

Sidewalk repair addresses safety hazards on a concrete pathway such as uneven slabs and cracking sections. Overall, it makes your property safer for everyone.

You won’t trip unexpectedly while walking the dog or deal with puddles of water collecting on the walkway leading to your home. With sidewalk repair, concrete pathways become smooth and stable.

We use polyurethane foam to repair sidewalks. Once injected under the concrete, the foam expands, fills gaps, and lifts the concrete all at once. In just 15 minutes, it’s strong enough to support the full weight of the sidewalk.

Signs You Need Sidewalk Repair

Sidewalk damage is easy to spot. Here are the key signs of concrete damage to look for:

Cracking and uneven section of sidewalk.
  • Cracks of any kind, especially those wider than ¼ inch
  • Uneven or sinking concrete
  • Concrete that moves or shifts when stepped on
  • Surface damage like pitting, flaking, and staining
  • Water or mud collecting on the sidewalk

If you notice even just one of these signs, schedule a free inspection from Bay Area Underpinning as soon as possible.

Is Sidewalk Repair Necessary?

Level concrete sidewalk.

We know you’d rather do anything else than deal with sidewalk damage. But we’ve seen what happens when concrete damage is ignored (it’s not anything good). Sidewalk repair is a necessary and beneficial service.

With our quick and modern sidewalk repair technique, your sidewalk looks better and becomes safer to walk on in just a few hours. No more worrying about your kids twisting an ankle or falling of their bikes when the sidewalk is lifted and stabilized.

This is an important job, and one that should only be handled by professionals. DIY options, like hydraulic cement, won’t solve the underlying issues. Work with Bay Area Underpinning for a lasting fix.
