Ground Modification

Slopes and embankments experience settlement, stability and erosion problems. Goettle offers various solutions to these problems. From landslides to construction cuts into hillsides, remediation or an earth retaining structure is required to maintain the slopes’ stability.

Ground anchors, micropiles, anchored reaction blocks, soil mixing, and jet grouting are all stability solutions that not only reinforce the soil but also control erosion. Anchored reaction blocks are ideal for newly failed slopes, applying loads to stabilize the soil. Ground anchirs and micropiles create a stabilized ground reinforcement system which resists the driving forces of the slope. Soil mixing and jet grouting are ground modification systems that are used to improve the characteristics of the soil within the slope.

A soil anchor is a device designed to support a structure and is used in geotechnical and construction applications. Also known as a ground anchor, percussion driven earth anchor, or mechanical anchor, it may be impact driven into the ground or run in spirally, depending on its design and intended force-resistance characteristics.

Soil anchors are used in both temporary or permanent applications, including supporting retaining walls and stabilization. Once installed and load-locked, and earth anchor exerts effort to the soil above it, with the soil in turn providing resistance.

When new construction is taking place directly adjacent to an existing structure, generally an underpinning system is necessary. Goettle has the ability to design and construct an underpinning system that will keep those existing structures safe, sound, and secure. Through traditional and shotcrete underpinning, we are able to temporarily support existing structures. Using traditional underpinning, soil is excavated from underneath the footers and replaced with concrete. If necessary, anchors are installed to resist lateral movement.

Our shotcrete underpinning system supports the existing structures but in a less obstructive manner. Soil is excavated only from the edge the footer down to the required depth and shotcrete is sprayed onto the cut to secure the soil in place. Anchors are then installed to secure the soil mass and support the structure.
