A sunken patio doesn’t just look bad — it pushes water back toward your foundation, kills your drainage, and turns your outdoor living space into a liability. We can lift your patio back to grade in 4–6 hours and restore proper drainage away from your home.
Why Patio Settlement Damages Your Home
When a patio settles, it usually slopes back toward the house. That reverses the original drainage plan and channels rainwater directly toward your foundation.
Over a few seasons, this leads to:
- Basement seepage
- Foundation cracks
- Mold growth on basement walls
- Sump pump failures during heavy rains
- Slab cracking from underneath as water continues to erode subgrade
Lifting the patio fixes the symptom (the visible settlement) AND the cause (the foundation-side drainage).
How Patio Lifting Works
For a typical residential patio, expect a 4–6 hour job:
- Inspect for cracks and settlement pattern
- Drill 5/8″ holes in a pattern designed for the specific lift needed
- Inject polyurethane foam under the slab
- Foam expands to lift the patio back to its original elevation (typically 1–4 inches)
- Verify the slope away from the house using a level
- Patch holes with color-matched cement
Patio is usable in 15 minutes after the lift.
Patio Leveling Cost in Bondurant
Pricing depends on patio size, how much lift is needed, access (some Bondurant patios have landscaping or hardscape obstructions), and whether crack repair is needed at the same time.
Compare to patio replacement: typically $4,000–$10,000, plus you lose use of your back yard for 2 weeks during demolition and curing.

Patio Settlement Causes in Bondurant
- Iowa clay soil expanding and contracting with seasonal moisture
- Heavy rain events eroding subgrade from edges
- Tree roots from your yard (especially from large maples and oaks) drawing moisture
- Sprinkler system installations that weren’t properly compacted after backfill
- Original installation on poor-quality fill or uncompacted soil
Frequently Asked Questions
My patio has spider cracks. Can you still lift it?
Yes — surface spider cracks don’t prevent lifting. We can fill them at the same time if you want.
What if my patio is around a pool?
Yes, we lift pool decks and patio coping regularly. Foam injection is safer than mudjacking near pool plumbing.
Will lifting affect my pavers or hardscape?
We lift the structural patio slab. Loose pavers can be removed and reset on top. We don’t lift hardscape stones — those are reset by hand.
How do I know if my patio settlement is causing my basement seepage?
If your basement gets damp during heavy rains AND your patio slopes back toward the house, that’s almost certainly the culprit. We can confirm during the free estimate.
Is this safer than mudjacking near my foundation?
Yes — polyurethane is significantly lighter than mud slurry. It doesn’t add weight to subgrade and doesn’t risk pushing water into your foundation.
