Sinking Porch

A sinking porch is a tripping hazard and a sign of structural damage. Our SettleStop™ PolyRenewal™ system can solve this problem.

A sinking concrete porch isn’t something you can ignore for too long. This uneven structure is both an eyesore and a significant tripping hazard, especially for older adults in your home. If left untreated, your porch can deteriorate further and seriously impact your foundation, leading to costly repairs.

Replacing concrete slabs in Alberta can be expensive and won’t always solve the cause of your sinking problem. Mudjacking, which is messy and washes out, won’t fix the underlying issue, either.

Instead, consider the SettleStop™ PolyRenewal™ system. This commercial-grade polyurethane foam stabilizes and potentially lifts your concrete porch, creating a safer environment for your family.

Make sure your porch is on a solid foundation.

What Is a Sinking Porch?

Porch slabs can settle or lower over time, making them uneven and unstable. Foundational damage or the soil underneath your porch are the most common reasons this happens.

Sinking porches are common in Alberta. They usually have cracks or tilt to one side, increasing the risk of trips and falls.

If your concrete slabs are sinking, you might notice other problems on your property, such as:

Don’t neglect these issues. Contacting a concrete lifting and leveling expert like Groundworks can prevent further damage to your home and maintain its structural integrity.

Why Your Home Has a Sinking Porch

Various factors cause a sinking porch, including:

  • Soil Settlement: Over time, the soil under one area of your porch can naturally compact while the soil under another area stays firm. This uneven settling often results in a sinking porch.
  • Soil Erosion: Water flowing beneath your porch can erode underlying soil, causing one section to sink. Downspouts directing rainwater too close to your porch might make erosion worse.
  • Flooding or Heavy Rain: A flood or excessive rain can wash away the soil under a section of your porch, causing it to sink.
  • Freeze-Thaw Cycles: Sinking can occur due to constant freezing and thawing of the ground beneath uneven porch areas, especially if you have expansive soils
  • Tree Roots: Your porch’s foundation can settle on one side when trees soak up moisture from its foundation. Roots could shift the soil and place pressure on your porch.
  • Poor Concrete Pouring/Curing: Inadequate concrete pouring or curing during construction might eventually cause your concrete to crack, shift, or sink.

Can You Fix a Sinking Porch?

DIY solutions or outdated methods like mudjacking might repair your sinking porch for a while. However, the problem will likely return if you don’t address its root cause.

That’s why Groundworks offers a comprehensive approach to concrete repair that goes far beyond a quick fix. We can inspect your porch, find out why it’s sinking, and potentially lift it with our PolyRenewal™ polyurethane injections. This lightweight two-part polymer foam solidifies in as little as 15 minutes and doesn’t erode, wash out, or release chemicals into the soil.

Depending on the extent of structural damage, we might also recommend foundation piers and other foundation repair solutions.

How to Fix a Sinking Porch

We follow these steps when repairing a sinking porch:

  • Sealing all cracks to prevent future water problems.
  • Performing regular maintenance.

Why Repair Your Sinking Porch Now?

Fixing your sinking porch as soon as possible provides these benefits:

  • Increase Safety: A sinking, sloped porch can cause trips and falls, especially among older adults and people with mobility issues.
  • Prevent Further Damage: Ignoring an uneven porch might lead to more cracks and damage. Early intervention prevents expensive repairs.
  • Avoid Water Intrusion: If your porch slopes toward your house, water might damage your siding and leak into your home.
  • Preserve Property Value: Removing unsightly cracks and lifting your porch can improve the appearance of your home, helping you maintain its value.
  • Safeguard Your Foundation: A sinking porch can lead to further foundational damage, compromising your family’s safety.

The work done promptly by Ryan and his team (Eryica, Ny) was excellent with the driveway lift that was extremely necessary. The team did a great job being on time and within the time allotted to complete the work. Would recommend to others if they need a professional job done while being efficient. Thank you again!

We got 3 quotes for driveway lifting. These guys were competitively priced and had good reviews on google so we hired them. I’m glad we did! They were very friendly, professional, and efficient. They did a great job and cleaned up afterwards. When James and his partner came back to seal the joints, the service was just as good as the first team. Thanks again!

Vincent Augert was very thorough and upfront about the cost and warranty.
He was very easy to deal with and most importantly, we never felt pressure during the whole quoting process.

Excellent service. Sales was pleasant and quote was thorough enough to proceed. The crew that came out to excavate, and install the interior and exterior basement systems was absolutely top notch – their work was neat and tidy, they showed up on time, and worked hard. To top it off, they (and all the folks involved) have to be the most pleasant contractors I’ve ever dealt with – and this is house #5 for us over the years! Thank you, Basement Authority. Highly recommend.
