Vacation Resort Pool

The Challenge

The pool had cracked and leaked, leading to water saturation of the underlying fill materials.

The challenge of this project stems from the condition of a pool constructed on fill materials, which had experienced significant issues over time. The pool had cracked and leaked, leading to water saturation of the underlying fill materials. This saturation accelerated the settlement process, further compromising the pool’s structural integrity. Additionally, the customer encountered a slope failure behind the pool just a few months prior to the planned treatment, which added complexity to the situation, making the stabilization and repair efforts more urgent and intricate. Addressing these interconnected issues required a comprehensive approach to both the pool structure and the surrounding terrain.

Key Facts

The Solution

The polyurethane injections process was utilized to fill the voids beneath the pool slab and to increase the bearing capacity of the fill materials below, ensuring long-term support for the pool.

The polyurethane injections process was utilized to fill the voids beneath the pool slab and to increase the bearing capacity of the fill materials below, ensuring long-term support for the pool. Additionally, a curtain wall of stabilized soils was created behind the pool to stabilize the slope and prevent further failure. The Groundworks method was specifically employed to fill the voids directly beneath the pool, addressing the immediate structural concerns. Preliminary concept discussions and budgeting were provided to the engineering firm to outline the scope of work. The project was contracted directly with the customer, while maintaining close coordination with the engineer, pool contractor, and corporate management to ensure seamless execution of the treatment plan.

The Impact

Repair completed ahead of schedule and 5% under budget.

The work was completed ahead of schedule, taking only eight days instead of the contracted 10-day term, despite encountering utility location issues that could have caused delays. The operation successfully strengthened the foundation soils by increasing their bearing capacity and stabilizing the underlying materials, ensuring the long-term stability of both the pool and the slope. Additionally, the project was delivered 5% under budget, demonstrating efficient resource management and effective problem-solving throughout the process. These outcomes not only met but exceeded the customer’s goals, providing both timely and cost-effective results.
