Administrators at Orange County, Florida Public Works had a pressing issue. Settlement was occurring along a quarter-mile stretch of a three-lane roadway. The culprit? Loose, sandy soils combined with a high water table. Before repaving could begin, stabilizing the supporting soil was crucial. This case study explores how the problem was addressed and resolved. This project showcases innovative solutions for common infrastructure challenges in areas with problematic soil conditions.

Powerful Polymers

AP Fill 700 was selected as the repair material for this project. Its low viscosity allowed for effective soil permeation, and its curing strength promised to create a permanent soil mass. These properties made AP Fill 700 the perfect choice for stabilizing the loose soil beneath the roadway. The selection of this material demonstrated the importance of choosing the right product for specific geotechnical challenges. AP Fill 700's unique characteristics ensured a robust and long-lasting solution.

Painless Procedures

A methodical approach was essential for this project. First, a large grid pattern for injections was carefully planned out. Each injection point was spaced five feet apart, and the depth of each injection reached approximately 15 feet. At each point, one gallon of material was injected per vertical foot. This systematic process ensured thorough coverage and stabilization of the problematic soil. The precise spacing and depth of injections were critical factors in the project's success. By following this detailed procedure, the team could address the soil instability comprehensively.

Rapid Results

This massive project was completed in about a week. As a result, the once-loose soil was successfully stabilized. The municipality now had a solid foundation to repave the quarter-mile stretch of road. In the end, Orange County Public Works had effectively addressed the settlement issue. The roadway was now ready for safe, long-lasting resurfacing. This efficient resolution solved the immediate problem and prevented potential future issues. The success of this project demonstrated the effectiveness of proactive infrastructure maintenance and the value of employing advanced soil stabilization techniques.
