This post features three case studies that highlight the versatility and effectiveness of the Deep Lock® process across a variety of applications.

## Deep Soil Stabilization at a Shopping Center

- **Location:** City Creek Center, Salt Lake City.
- **Problem:** A trench filled with pea gravel began settling, affecting underground power lines.
- **Solution:** The trench was stabilized using structural polymers.
- **Process:** An Alchatek consultant developed an injection plan, and the geotech crew installed 10 injection tubes 30 feet deep, pumping approximately 1 gallon per vertical foot.
- **Outcome:** The site work was completed in just two days, allowing for the rapid continuation of the construction work.

## Deep Soil Stabilization for New Construction

- **Location:** A commercial construction site.
- **Problem:** The need to stabilize gravel and soil held in place by sheet pile panels between the panels and the foundation.
- **Solution:** Structural polymers were used due to their ability to permeate soil and encapsulate gravel into a solid mass.
- **Process:** The crew injected the polymer to a depth of about 12 feet, grouting to refusal, ensuring the entire layer of soil and gravel was locked in place.
- **Outcome:** The stabilized soil and gravel provided a solid supportive wall for the foundation when the sheet piles were removed, and the gap filled with cement.

## Deep Soil Stabilization at a Two-Story House

- **Location:** A two-story house in North Carolina, built on poorly compacted fill dirt.
- **Problem:** The house showed signs of settling, with interior cracks and uneven floors.
- **Solution:** A structural foam was used for its high-strength, hydro-insensitive properties, ideal for densifying soil and stabilizing foundations.
- **Process:** 18 injection tubes were installed to depths of 7 feet and 3.5 feet, injecting foam beneath exterior footings and load-bearing interior walls.
- **Outcome:** The stabilization process not only densified the soil and stopped the settlement but also achieved a half-inch lift both from exterior and interior injections, impressing both the customer and the engineer.

These case studies demonstrate the adaptability and effectiveness of the Deep Lock® process in addressing diverse soil stabilization challenges. From commercial construction sites to residential properties, Deep Lock® provides a reliable and efficient solution for soil stabilization needs.
