Monday, March 24th, 2025 by Mike Gray

Challenge

Problem:
A homeowner in Livermore, CA, noticed that their pool deck was sinking, causing it to pull away from the pool. This not only created an unsightly gap but also posed a potential tripping hazard and risk of further structural damage. Concerned about the safety of their family and the long-term integrity of their pool area, the homeowner contacted Foundation Repair of CA for a free evaluation and a permanent solution. They wanted to avoid the cost, mess, and hassle of removing and replacing the damaged concrete while ensuring the repair would extend the life of their pool deck.

Solution

Solution:
After a thorough inspection, our experts recommended a two-part solution using PolyLevel® Foam Injection and NexusPro® Joint Sealant to lift and stabilize the pool deck and seal the gaps.

PolyLevel® Foam Injection:

Our team drilled small port holes in a precise grid pattern across the affected area of the pool deck.
We injected a high-density polyurethane foam beneath the concrete, which expanded to lift and level the sinking sections.
Once the desired elevation was achieved, we carefully filled the port holes, restoring a smooth and even surface.

NexusPro® Joint Sealant:

We thoroughly cleaned the joints and, where applicable, inserted a backer rod to provide additional support.
A flexible, UV-resistant silicone sealant was then injected into the joint gaps to prevent water infiltration, which could cause future sinking or erosion.
The sealant was finished with a layer of fine sand for a clean and professional appearance.

Results:
The PolyLevel® Foam Injection successfully lifted and stabilized the pool deck, eliminating the hazardous gap and preventing further structural damage. The NexusPro® Joint Sealant created a durable, waterproof barrier to protect against future soil erosion and concrete movement. The homeowner was delighted with the results, appreciating the quick, clean, and minimally invasive process.
