What Pool Deck Cracks or Settling Tells You About Your Concrete Repair
Pool deck settling shows as deck sections dropping, cracking, or tilting around the pool, often with lips at the joints and water pooling toward or away from the pool. The soil around a pool is repeatedly wetted by splashout, rain, and backwash, so it erodes and consolidates, leaving voids the deck settles into. In Alabama's clay, this movement is pronounced, and a settling pool deck is both a trip hazard and an eyesore in a high-use area. Lifting the settled slabs with foam restores a level, safe deck without the cost and disruption of demolition around the pool.
Alabama's rain and the constantly wet soil around pools drive frequent pool-deck settling, making pool-deck leveling a common concrete repair for APS across Birmingham, Huntsville, Mobile, and Columbus, Georgia.

What Causes Pool Deck Cracks or Settling in Alabama Homes
Constant Moisture Around the Pool
Splashout, rain, and backwash keep the soil around a pool wetter than elsewhere, accelerating erosion and consolidation that leave voids under the deck.
Erosion and Voids
Water moving through the saturated soil around the pool carries fines away, forming voids that the deck slabs settle into unevenly.
Expansive Clay Movement
Alabama's clay swells and shrinks dramatically in the frequently wetted pool-side soil, lifting and dropping deck sections over time.
Backfill Settlement
Pool decks poured over backfill placed during pool construction settle as that fill consolidates, which is why decks often move within a few years of installation.
Signs You Should Not Ignore
- Deck sections lower than the pool coping or adjacent slabs
- Cracks radiating across the deck
- A trip lip at the joints
- Water pooling on the deck instead of draining
- Gaps opening between the deck and the pool shell

Frequently Asked Questions
Can a settling pool deck be lifted without draining the pool?
In most cases yes. Polyurethane foam injection lifts the deck slabs from above by filling the voids beneath them, so the work is typically done without draining the pool or demolishing the deck.
Why do pool decks settle so often?
The soil around a pool is the wettest on the property from splashout, rain, and backwash, and pool decks often sit on construction backfill. Both cause the soil to erode and consolidate, so the deck settles.
Is a settling deck a safety issue?
Yes. The lips at settled joints are trip hazards in a wet, high-traffic, often barefoot area, and poor drainage sends water where it should not go. Leveling restores a safe, properly draining deck.
Foam lifting or replacement?
Lifting is usually the better option: it is faster, less expensive, and avoids demolition around the pool. Replacement is only needed when the concrete itself is badly deteriorated. APS advises which fits.
