Traditional methods for anchoring small structures such as towers have been accomplished by employing cables and deadman anchors. Excavation, carpentry, concrete & reinforcing steel skills, and equipment/material access are all required to provide a safe installation for the deadman anchors. Many locations are remote and have environmental and/or excavation limitations due to the presence of trees, shallow bedrock, streams, and/or cut slopes. For deadman anchor installation, a large surface area needs to be cleared and excavated, which is not always possible.
A Mid-Atlantic State Department of Transportation had a swinging anchor bridge requiring anchors with a working design load of 21 tons per anchor. The bridge was only accessible through a ford when the water levels in the stream were down. The presence of shallow shale, siltstone, and sandstone with little overburden made galvanized Self-Drilling SuperMicropiles™ an ideal option. GeoStabilization International® provided a design/build/warranty anchor system comprised of galvanized Self-Drilling SuperMicropiles™ of up to 30 feet in length. This design included sacrificial nails for verification purposes, which were tested to 42 tons – 200% of the design load.
Micropiles (also called pin piles, mini piles, and root piles) make up grouted pile foundations. These foundations consist of small diameter drilled holes, a steel reinforcement casing that may extend past the anchor head, and high-strength cement grout. Construction and geohazard mitigation professionals use cast-in-place micropiles to underpin new and existing foundations to prevent structural instability due to soil erosion and other issues.
The expert team at GeoStabilization International® uses piling in weak soils to reinforce foundations in any geological environment. We’ve used various micropile technologies to repair and strengthen roads, bridges, communication towers, among others.
GeoStabilization installed grouted ground anchors, also known as tieback anchors, to transfer a structure’s tensile load into the ground. This type of anchor becomes necessary when the environment doesn’t support deadman anchors and other designs. This solution was provided for mitigating various geohazards using innovative and dynamic technology.
Many types of structures exist on remote sites that cannot accommodate traditional foundation underpinning due to poor ground conditions, lack of available space, or lack of access. GeoStabilization’s geohazard mitigation teams get around these limitations by using SuperMicropiles™. This foundation solution provides reliable stabilization and fast installation in any environment.
GeoStabilization’s crews can drill micropiles to a total depth of 160 feet for a stable foundation solution. They’ve installed SuperMicropiles™ on cliffsides, in existing basements, during excavation shoring projects, and in many other applications.
Installing foundations and ground anchors for geohazard mitigation requires drill rigs that can fit and operate in the most demanding environments. GeoStabilization International® crews have access to various purpose-built piling drill rigs to handle any stabilization project regardless of location, design depth, or other factors.
Wagon Drills can be maneuvered via helicopters, crane-basket mounted drills, walking drill rigs, and other rigs built to handle the unique challenges of reinforcing an active landslide. While working on sites that could collapse at the slightest disturbance, GeoStabilization uses helicopters and high-reach equipment to avoid triggering a bigger disaster.
