The key to this solution was Alchatek's AP Lift 440 polyurethane foam. This powerful polymer was chosen for its soil stabilization, load-bearing, and lifting capabilities. Deep soil injections were planned to address the underlying issues. The foam's expanding properties would displace water and stabilize the soil base. This method offered a non-invasive alternative to traditional approaches like helical piles.
The process began with a thorough site assessment. The technicians analyzed soil saturation and settlement patterns. Based on this data, a 3-foot by 5-foot injection grid was designed. Next, holes were drilled through the bottom of the pool, and injection rods were installed. AP Lift 440 was injected beneath the structure. As a result, the expanding foam displaced water and stabilized the soil base. Following this, the pool was lifted by 3.5 inches. Finally, the pool deck was adjusted to match the new level.
The pool was successfully stabilized and leveled with minimal disruption. Moreover, there was no need for extensive excavation. This method proved to be both effective and efficient. The foam injections effectively displaced water and stabilized the soil. Additionally, the lifting process was precise, raising the pool by exactly 3.5 inches. Perhaps most importantly, this solution was cost-effective. It proved quicker and more economical than complete pool replacement.
