Swimming pools are meant to be a source of relaxation and enjoyment. However, when soil erosion threatens the stability of a pool, it can quickly become a homeowner’s nightmare. This was the case for one property owner who noticed significant swimming pool settlement issues. Upon further investigation, large voids were discovered under the pool due to soil erosion from a faulty seawall. Fortunately, Seawall Repair Network® contractor EnviroMarine Services was called in to address the problem.
Repair Materials
The key to solving this issue lies in the choice of repair materials. SW-RP1 is an environmentally friendly, specially formulated high-density polymer foam. This innovative material combines strength and flexibility, making it ideal for seawall repairs. Moreover, SW-RP1 expands and hardens upon injection, effectively filling voids and stabilizing the soil behind the seawall. As a result, it provides a long-lasting solution that can withstand the dynamic forces of water and soil movement.
Procedures
First, injections of SW-RP1 were made directly behind each panel joint of the seawall. This crucial step filled existing voids and strengthened the soil, essentially transforming it into a solid, bedrock-like substance. Next, attention was turned to the installation of a hydrostatic pressure control system. To achieve this, technicians cored through the weep hole channels and the layer of polymer behind them, extending into the soil on the landward side. Subsequently, pressure-release filters were installed to allow excess water on the landward side to flow into the ocean while keeping supporting soil in place. Finally, cracks in the seawall caps were repaired using high-strength concrete repair materials, restoring strength and integrity to the structure.
Results
The entire repair process was completed in just two days, showcasing the efficiency of the chosen methods and materials. As a result of these repairs, the property owner was able to proceed with pool repairs without fear of recurring issues. The swift resolution of this complex problem highlights the effectiveness of Seawall Repair Network® rehabilitation techniques. By addressing the root cause of the pool settlement, the contractor not only fixed the immediate issue but also provided a long-term solution for the property owner.
