A homeowner in Tampa, FL was in the middle of building a new inground swimming pool when troubling signs of settlement appeared. Cracking was visible from one side of the pool shell to the other, with the most severe damage near the deep end.

An engineering evaluation determined that the pool’s underlying soils lacked the density to support the structure long-term. Instead of traditional underpinning, the engineer recommended a faster, more precise solution: polyurethane chemical grouting.

The homeowner chose Helicon to carry out the work, knowing our team specializes in soil stabilization for residential and commercial projects across Tampa Bay.

Injecting stabilization materials under a partially built pool requires extreme precision. The challenge was to:

• Place material accurately beneath and around the shell without overfilling
• Ensure uniform stabilization around the deep end, where loads are highest
• Complete the project quickly so pool construction could continue without delay

Helicon’s experienced crew executed the process with efficiency—completing the entire job in just one day.

Helicon followed the engineer’s stabilization plan using two-part polyurethane grout injections.

• Injection Points: Material was installed through 26 injection locations around the pool perimeter
• Precision Control: Foam expanded beneath the pool, filling voids and compacting loose soils
• Strength & Protection: The result was a dense, water-resistant base capable of supporting the pool for decades

By the end of the project, over 670 pounds of grout had been injected, permanently stabilizing the site.

The Results

With soil stabilization complete, the pool structure is now:

• Fully supported with no risk of future settlement
• Protected against soil washout and water intrusion
• Ready for contractors to safely finish construction

The homeowner can now move forward with confidence, knowing their investment is secure and their pool will remain stable for years to come.
