Why Is Your Concrete Sinking?
Why Is Your Concrete Sinking?
Concrete can sink for many reasons, some of which may not be visible to the naked eye. Let’s take a look beneath the surface to uncover what might be causing your concrete to fail.
1. Soil Erosion
One of the biggest culprits of concrete failure is soil erosion. Without proper drainage, rainfall can seep beneath your concrete, washing away the supporting soil. As the soil erodes, the concrete begins to sink, leading to cracks and uneven surfaces. An underground water leak can cause the same issue.
2. Poor Soil Compaction
Improper soil compaction is another frequent cause of sinking concrete in driveways, garage floors, patios, stoops, basement floors and more. If the soil isn’t properly compacted before pouring concrete, the weight of the slab will eventually compress the loose soil beneath it. Over time, this causes the concrete to settle and crack.
3. Freeze-Thaw Cycles
The cold winter nights followed by sunny days in Colorado contribute to sunken concrete. Snowmelt seeps into the pores of the concrete and into the spaces between slabs. When temperatures drop, the trapped water freezes and expands, creating internal pressure. As it melts, it leaves behind voids beneath the concrete. Over time, these voids cause the slab to sink.
4. Expansive Clay Soil
Similar to freeze-thaw cycles, expansive clay soil is a major issue in Colorado, especially along the Front Range and Eastern Plains. This type of soil swells when wet and shrinks when dry. As it dries and contracts, it leaves behind voids that no longer support the concrete, leading to gradual sinking and cracking.
How to Fix & Prevent Sinking Concrete
Now that we’ve covered the causes of sinking concrete, let’s discuss the solution: PolyLevel Foam! This lightweight, durable foam lifts and levels your concrete back to its original position. Unlike traditional mudjacking, PolyLevel won’t wash away or break down over time.
Whether your concrete is still in good condition or you want to repair your concrete, here’s what you can do:
- Schedule a Free Concrete Inspection – Check for voids beneath your concrete before they become a bigger problem.
- Seal Joints & Cracks – Prevent water from seeping under your concrete with a durable sealant like NexusPro, which lasts longer than traditional caulking.
- Apply a Penetrative Sealant – Protect your concrete from absorbing moisture with SealantPro, a permanent chemical bond that extends the life of your concrete.
