Concrete Jack performs stoop repair by raising settled concrete stoopes back to their original position using slab jacking and foam jacking. This corrects settlement problems to fix trip hazards, correct improper step heights, improve drainage and fill voids under unsupported concrete. Sometimes, foundation piers are required to lift settled stoopes, but this is pretty infrequent.
What causes the need for stoop repair?
Settlement is the most common reasons homeowners and property managers require stoop repair. When your home is built, particularly if it has a basement, or a crawlspace, the material placed under the concrete stoop is not compacted properly. Over time, the backfill soil settles, which reduces support of the stoop. Some stoopes sit on top of special walls so they don’t settle. In this case, voids form under the stoop, but it doesn’t necessarily sink. If the voids are large and extensive enough, they can cause the concrete stoop to start to settle.
The need for drainage improvement usually results from stoops settling so much that they slope towards the house instead of away. This is common with stoops that run alongside homes with basements. When water flows towards a house due to an incorrectly sloped stoop, it can cause moisture problems and foundation problems. Lifting your stoop to establish good drainage is much less expensive than repairing your foundation or re-waterproofing your basement.
Filling voids is a really common stoop repair. If there are voids (air spaces) below your stoop, it’s pretty much guaranteed to start settling or deteriorating eventually. Filling voids before a stoop starts to settle is much quicker and easier than lifting a stoop after it’s broken and settled. An ounce of stoop repair prevention is worth a pound of stoop repair cure.
Stoop Repair Methods:
We perform three different process, slab jacking, foam jacking, and piering, for stoop repair. All three processes work to lift settled stoop concrete back to its original position. Mud jacking works to raise settled stoop concrete by injecting sand-based grout under the concrete. Foam jacking raises and supports settled concrete stoops by injecting high density polyurethane foam under the concrete. Piering is rarely needed, but uses steel piers either pushed or screwed into the ground, and mechanical jacks to lift the stoop back into place.
Stoop problems that we repair using mud jacking include voids (air spaces) under stoops and stoop settlement. The most common cause of these problems is settlement of the underlying soil because it wasn’t packed down when the house was built or stoop was installed. Generally, it takes about 10 years for the backfill material to settle on its own after it is installed. Mud jacking and foam jacking tend to have slightly lower chances of resettlement than concrete replacement, which is the more common, and expensive, method for repairing sinking stoops.
Stoop Repair Cost:
Generally, stoop repair using slab jacking and foam jacking costs around 1/2 the price of replacement. Mud jacking and foam jacking for stoop repairs generally take about 20 minutes per piece, but can take a bit longer if the sections have all settled differently. You may walk on stoops that have been repaired using mud jacking or foam jacking during and immediately afterwards. Piering is the most expensive of the three processes, and is used occasionally, generally when stoopes are exceptionally heavy relative to their area.
