- Ideal for non-caving soils
- Rapid installation (schedule savings)
- 20-50% savings versus deep foundations and over-excavation
- Minimal spoils and haul-off costs
The Geopier X1® system is our newest “drill and fill” solution. This system is ideal for non-caving soils that stay open during drilling but can also be used as a displacement system in clean sands. Geopier X1 piers are constructed using a track-mounted auger to drill out unsuitable soils and a specialty mandrel mounted to a mast rig to construct the Rammed Aggregate Pier® (RAP) elements. The specialty mandrel and larger equipment allows for significantly faster and cheaper pier construction. The end result is a dense column of aggregate surrounded by stiffened matrix soils that provide excellent settlement control and allow for higher bearing capacities.
- Non-caving soils such as clays, silts, and sands with high fines content
- Clean sand profiles
- Organic soils using cemented treated aggregate (CTA)
The Geopier X1® installation process consists of drilling out unsuitable soils to a desired design depth and then constructing a dense column of aggregate using a patented tamper. The pier is constructed in 3-foot-thick lifts using well-graded aggregate, open-graded aggregate, or sand. The installation process imparts significant lateral pressures into the adjacent matrix soil, which creates excellent coupling and stiffens the soil.
