The owner of an apartment complex overlooking Stephen Foster Creek in Gainesville, Florida, faced a critical issue. The embankment below showed signs of erosion, creeping dangerously close to the structures. With each passing day, the unstable ground crept ever closer to the foundations of the residential structures, posing a significant threat to both the buildings and the safety of their inhabitants. The situation demanded immediate attention and a robust, long-term solution to safeguard the property and ensure the well-being of its residents. The predominantly sandy composition of the local soil posed a challenge for stabilization. Consequently, the geotech firm Stable Soils was called in to address this pressing concern.

Powerful Polymers

After conducting a thorough site assessment and carefully evaluating various potential solutions, the team at Stable Soils identified AP Soil 600 as the optimal polymer for this challenging project. This choice was strategic. AP Soil 600 features low viscosity, a crucial characteristic that allows it to effectively penetrate and permeate sandy soil. Moreover, its impressive strength after curing promised long-lasting stability for the embankment.

Painless Procedures

Injection points were established in a zigzag pattern, spaced 18 inches apart. The team drilled 10 feet below grade to reach the optimal depth for soil reinforcement. Low-pressure injection was key to the operation’s success. This approach prevented the chemical from fracturing the soil or moving in unintended directions. The injection rod was slowly extracted, allowing for precise distribution of the polymer. One gallon was applied every five minutes and every vertical foot. In total, a 240-foot row of soil stabilization resin was installed.

Rapid Results

The impact of this intervention was immediately apparent. During a subsequent heavy rain event, surrounding areas suffered minor washouts while the stabilized soil remained completely unaffected. The stark contrast in performance served as a powerful testament to the effectiveness of the AP Soil 600 polymer and the precision of its application. The apartment buildings, once precariously positioned near the eroding embankment, now stand secure and protected, their foundations no longer at risk from the relentless forces of erosion.
