Sidewalk & Walkway Replacement in Green Bay, WI
Green Bay Concrete Pros replaces sidewalks and walkways across Green Bay and Brown County, Wisconsin. We are a licensed and insured concrete contractor. Approach walks, front walks, and public sidewalks that have heaved into trip hazards come out and get repoured to a safe slope, jointed, and isolated from the drive and the steps so they move without tearing.
Each new panel is four inches thick on a compacted crushed-stone base, poured in 4000 PSI air-entrained concrete and reinforced with mesh or fiber. Air entrainment matters on a walk more than almost anywhere, because a sidewalk takes salt underfoot all winter and freezing water flakes an unprotected surface. A walk poured on bare graded clay, with no base and no isolation joints, heaves panel by panel until the whole run steps up and down.
Trip Hazards and Raised Panels
A sidewalk fails one panel at a time. Frost lifts a slab above its neighbor and the lip becomes a toe-catcher and a liability. We do not chase the lip. We pull the panel that heaves, fix the base that let it heave, and pour it back flush so it stays level with the run beside it.
Slope and Frost Separation
A walk has to shed water and stay separated from the frost it fights. We build in a gentle cross slope so rain runs off instead of ponding and icing over. Where the walk runs alongside the house or a slab, we keep frost from telegraphing across by isolating the concrete, so one part can move without dragging the next with it.
Isolation Joints at the Drive and Steps
The trouble spots on a walk are where it meets something solid. Butt a sidewalk tight against a driveway or a set of steps and the two fight when frost lifts them at different rates. We set an isolation joint at every one of those meetings, a clean break filled to flex, so the walk and the thing next to it move on their own.
What It Costs
Sidewalk and walkway replacement in Green Bay runs about $3,000 to $7,000. A few replacement panels sit low. A full front walk, a long approach walk, or one that needs the base dug out and rebuilt sits higher. Every walk gets a free written estimate first.
Have a lifted slab someone is going to trip on? (920) 555-0163 gets you a free look. If the walk ties into a set of porch steps, we can reset both so they meet clean, and we pour walks in Howard and De Pere as well.
One sidewalk slab is higher than the next. Is that a trip hazard?
Yes, and in Green Bay a raised slab on a public walk is usually the property owner's problem to fix. Frost heaves one panel above its neighbor and the lip catches a toe. Grinding shaves a small lip, but a panel that keeps lifting is sitting on a base that heaves. Replacing it on a compacted base is what stops the panel coming back up next winter.
What slope does a walkway need?
Enough cross slope to shed water without being steep enough to be unsafe, and it has to stay walkable for anyone using it. We set a gentle pitch so rain runs off the walk instead of ponding and freezing on it. A flat walk holds water, and water that freezes on a sidewalk is both a hazard and what drives the surface to spall.
Why do sidewalk panels crack and separate?
Frost and a missing joint. Green Bay ground freezes deep, and a walk with no isolation joint where it meets the driveway or the steps has nowhere to move, so it cracks and lifts apart at those points. We isolate the walk from anything solid it butts against and saw-cut joints along its length so it moves without tearing.
Can you replace just the bad section of walk?
Often, yes. A sidewalk is poured in panels, so we can pull the heaved or broken sections, rebuild the base under them, and pour new panels that tie into the sound ones. If most of the run is cracked or the whole base is bad, replacing the full walk is the better value. We tell you which after we look at it.
