How ECP Helical Piers Transform Hillside Properties with Concrete Retaining Walls
California’s scenic cliffside homes and hillside properties offer breathtaking views but come with inherent risks such as seismic activity, unstable soils, and landslides. To mitigate these risks, robust retaining walls are often essential. In partnership with Earth Contact Products (ECP), Foundations on the Level has been tackling these challenges with expertly engineered solutions. Below, we explore two recent projects that highlight their innovative approach.
Slope Stabilization for a Hillside Investment in San Clemente, CA

When investors purchased a hillside property in San Clemente, they recognized the urgent need to secure the slope. Peter Zoschak, owner of Foundations on the Level, proposed an impressive solution: a monolithic concrete retaining wall reinforced with ECP’s helical systems.
The design featured:
- Wall Dimensions: 16 inches thick, 10 feet tall (5 feet above ground, 5 feet below).
- Reinforcement: Helical tieback anchors and piers embedded in the concrete, ensuring stability and long-term support.
This solution not only secured the property but also allowed for safe renovations, increasing the property’s value.
Invisible Strength in Dana Point, CA
Another homeowner in Dana Point required slope stabilization but wanted the retaining wall completely buried for aesthetic reasons. Peter’s team designed a subterranean retaining wall reinforced with:
- Helical Tiebacks: For lateral stability.
- Helical Piers: Providing vertical support.
This hidden support system ensures the home remains secure without compromising the property’s visual appeal. Thanks to ECP’s high-quality products, the wall will protect against soil movement for years to come.
