Why is My Pool Deck Lifting? Insights and Solutions from FoamWorks

At FoamWorks, we often encounter homeowners baffled by their uneven or lifting pool decks. This common problem can be both a safety hazard and a detriment to your property’s aesthetic. Understanding why your pool deck is lifting can help you choose the right repair methods to ensure a long-lasting and safe pool area. We’ll explore the causes of this issue and how our innovative concrete lifting techniques can provide an effective solution.

What Causes Pool Decks to Lift?

1. Soil Erosion and Settlement

The most common cause of a lifting pool deck is soil issues beneath the concrete. Soil erosion and settlement can occur due to various reasons, including inadequate compaction at the time of installation, the natural settling of soil over time, or erosion facilitated by water runoff. As the ground underneath loses its uniformity and density, voids are formed, and without adequate support, concrete slabs begin to move and eventually lift.

2. Water Intrusion

Improper drainage can lead to water pooling under your pool deck. This not only increases the risk of soil erosion but can also cause the soil to swell, lifting the concrete slabs above. Frequent or prolonged exposure to water can exacerbate these effects, leading to significant lifting and unevenness of the deck.

3. Tree Root Growth

Another possible cause of a lifting pool deck is the growth of tree roots underneath the concrete. Roots grow naturally towards sources of water, and under a pool deck, they can find the moisture they crave. As they grow, they can exert upward pressure on the concrete, causing it to lift or crack.

4. Freeze-Thaw Cycles

For regions that experience cold winters, freeze-thaw cycles can be a destructive force. When water seeps into cracks or joints in the concrete and then freezes, it expands. This expansion can exert upward pressure, lifting the concrete. Repeated freezing and thawing can exacerbate these lifts and lead to significant damage over time.

FoamWorks’ Solutions: Concrete Lifting and Leveling

Understanding the problem is half the battle. At FoamWorks, we specialize in addressing the root causes of lifting pool decks through a method known as concrete leveling or slab jacking. Here’s how we tackle these issues:

1. Polyurethane Foam Injection

Our preferred method for lifting and stabilizing concrete pool decks is polyurethane foam injection. This process involves drilling small holes into the affected concrete slabs and injecting a high-density foam underneath. The foam expands to fill voids and raises the concrete to its original level. This method is not only effective but also minimally invasive and environmentally friendly.

2. Advantages of Polyurethane Foam Injection

  • Speed: The process can be completed quickly, often within a day, minimizing disruption to your pool area.
  • Precision: Foam injection offers precise control over the lift, allowing us to gently raise the concrete slab to the exact desired level.
  • Strength: The injected foam is durable and resistant to water, which helps prevent future soil erosion and protects against similar issues.
  • Environmentally Friendly: The materials used are eco-friendly and less invasive compared to traditional mudjacking.

Preventive Measures and Maintenance Tips

While repairs are sometimes necessary, prevention is always better than cure. Here are some tips to help prevent your pool deck from lifting:

  • Ensure Proper Drainage: Make sure that your pool area has adequate drainage to prevent water from pooling under the deck. Regularly clean your gutters and downspouts to direct water away from the concrete.
  • Regular Inspections: Check for cracks and signs of movement regularly. Early detection can prevent minor issues from becoming major problems.
  • Tree Management: Be mindful of tree placement near your pool deck. Regular trimming and monitoring of root growth can mitigate the risk of damage from roots.
