Concrete Lifting

Cause #1: Poor Compaction

The area around your home's foundation often contains loose soil and fill from construction. Tennessee homes with basements require over-excavation for foundation walls. After pouring, this area is backfilled, but the loose fill tends to settle over time. Consequently, concrete structures in this “compaction zone” sink as the underlying soil settles.

Cause #2: Water

Water compacts soil, and poor drainage combined with rain and snowmelt evacuates air pockets beneath your concrete. As moisture dries, voids form, causing the soil to collapse and take the concrete with it, resulting in settling, sinking, and cracking. Flooding from leaks can also lead to these problems. However, our water-resistant poly foam can improve underlying water issues that caused the damage.

Cause #3: Inadequate Drainage

Constant water under concrete can lead to failure. Many homeowners overlook grading, allowing water to flow toward their foundation. When you notice inadequate drainage, it’s crucial to address it. Leaky gutters, downspouts, and excessive watering near concrete can cause the soil and concrete to sink. Correcting drainage along with leveling your concrete with ‘58 Foundations and Waterproofing is essential.
