Micropiles and Ground Anchors
Our engineers can design and install micropile supports and anchor systems in virtually any geological setting. Our specialized equipment enables installation at sites with severe access limitations and obstructions. We design foundations for wind turbines, towers, transmission lines, commercial and residential buildings. Our designs can reduce costs, limit daily trips to construction sites, and reduce project completion time.
Launched SuperMicropiles TM – Nothing matches the speed of a Launched SuperMicropileTM installation. Designed to resist landslide movement, these systems also can provide bearing support for a variety of retaining walls and structures.
Ground Anchors – Our engineers can design and install ground anchors for transmission lines, wind turbines, and towers. High capacity anchors also repair existing cantilever and reinforced earth retaining walls that show signs of distress.
A proposed new single family home was to be constructed between two existing buildings along a city street. The structure was designed to use the maximum buildable space, three feet from property lines in all directions. It also was designed with a full basement requiring up to 13 feet of vertical excavation. Neither of the adjacent properties had a continuous footer depth equal to that of the newly proposed structure. Those challenges required the owner to seek a contractor specializing in zero-lot-line shoring methods. Soil Nail Launcher, Inc.’s partner company GeoStabilization was contracted to provide the excavation shoring for this site.
Although only one owner sought our services, our engineers and crews had to work closely with three additional parties in order to complete the project: The Town of Telluride and the two adjacent property owners.
The Town of Telluride owned and controlled Oak Street to the east and an alley to the west of the excavation. We needed to assure the Town of Telluride that we would prevent sloughing or settlement of utilities and the roadways, that the shoring would not cross property lines, and that we would not work from the roadway.
The building to the north was a restaurant, and the building to the south was a bank. Of course, our shoring would need to prevent settling or subsidence of either or the existing structures. Nor could we cross either of those property lines with any element of shoring. Our shoring between the buildings, in its end-state, also needed to be covered with dirt or landscaping.
A vertical micropile shoring was chosen as the appropriate design-build method for this particular site; pile driving equipment was too large to access this site. Injection anchor micropile techniques were used on this project. The client, the neighbor, and the Town were pleased with both the process and the results.

A precariously perched two-lane roadway in Colorado National Monument needed to be widened. The Central Federal Lands office of the Federal Highway Administration designed a mechanically stabilized earth retaining wall to facilitate that widening. In order to work quickly, maintain a small footprint, and work within a limited excavation, the FHWA selected Launched Micropiles as the solution for building the foundation to that wall. Soil Nail Launcher installed the Launched Micropiles and met the FHWA goal of a fast solution that would minimize the size of the excavation. Moreover, Launched Micropiles also proved to be an economical solution.
