Common Signs Your Patio Is Settling
Patio settlement often develops gradually, making it easy to overlook until the uneven concrete becomes difficult to ignore. A single low corner may look minor today, but continued movement can lead to safety hazards, drainage issues and added damage over time. If you're seeing any of the following, your patio may be settling.
Causes
What Makes a Patio Sink?
Most sinking patios aren't the result of failing concrete—they're the result of changes in the soil beneath it. When the supporting soil settles, washes away or shifts, the concrete loses the stable base it needs and begins to sink. Identifying the underlying cause is the first step toward a long-lasting repair.
What Happens If a Sinking Patio Goes Unrepaired?
Stage 1
Early Settlement
One section of the patio starts sitting slightly lower than the surrounding concrete. Homeowners may notice small puddles after rain, a slight slope or patio furniture that no longer sits level. While the damage may look minor, it’s often the first sign that the supporting soil beneath the patio has started to shift or settle.
Stage 2
Uneven Surfaces & Poor Drainage
As the supporting soil continues to settle or erode, the height difference becomes more noticeable. Trip hazards increase, cracks may begin to develop, and water can collect against the home or pool in low areas instead of draining away. The patio ends up less safe, less pleasant to use and more susceptible to continued settlement.
Stage 3
Advancing Damage
Left unrepaired, settlement can continue until more sections of the patio sink, cracks widen, and the concrete becomes harder to restore. Correcting the underlying soil problem early often makes it possible to lift and stabilize the patio rather than replace it, helping homeowners avoid larger repairs and higher costs.
How Blackburn Foundation Repair Repairs a Sinking Patio
If you're dealing with a sinking patio in Sioux Falls, stabilizing the soil beneath the concrete is often a better long-term solution than replacing the patio. Using PolyLevel®, Blackburn Foundation Repair fills the voids beneath the slab, stabilizes weak soil and gently raises settled concrete toward its original position.
