Geopier Rammed Aggregate Pier Systems

Geopier X1® Rammed Aggregate Pier Elements A PRE-AUGERED "DRILL AND FILL" TECHNIQUE As with our other Geopier RAP methods described above, X1 RAPs are ground improvement elements that reinforce unsuitable soils to provide improved bearing capacity and settlement control for traditional shallow footing and slab-on-grade support.

Foundation Pier Systems

Geopier Rammed Aggregate Pier ® Design Our Rammed Aggregate Pier ® (RAP) ground improvement systems consist of densified columns of stone and gravel surrounded by a stiffened matrix soil.. These foundation piers are ideal for nearly all soil types and design applications. There are "drill and fill" solutions for non-caving soils (silts and clays) and there are "displacement" solutions ...
The Geopier Impact® system is our solution to soils that simply won't stay open during drilling . Impact piers are a displacement type system that uses a steel pipe mandrel outfitted with a patented compaction chamber to penetrate through caving soils and construct piers from the bottom up. This installation method allows for the construction of high-quality Rammed Aggregate Piers (RAPs ...

Ground Improvement
Geopier Rammed Aggregate Pier ® (RAP) systems are ground improvement technologies that create a densified column of aggregate surrounded by a stiffened matrix soil. Rammed Aggregate Piers are a versatile ground improvement solution designed to reinforce poor soils through the use of patented mandrels. These systems are ideal for nearly all soil types and applications. Rammed Aggregate Pier ...
The Impact® System The Geopier ImpactTM system creates Rammed Aggregate Pier ® (RAP) elements using a patented vertical ramming process. The Geopier ImpactTM system uses a patented displacement mandrel to reinforce good to poor soils, including loose sand, soft silt and clay, mixed soil layers, uncontrolled fill, contaminated soils and soils below the groundwater table. The displacement ...

Advantages of Rammed Aggregate Pier Systems Over Stone Columns
Geopier Rammed Aggregate Pier ® (RAP) systems are efficient and cost-effective solutions for the support of settlement- sensitive structures. By avoiding massive over-excavation, as well as excess soils, these systems are considered the gold standard in ground improvement across Canada.
The Geopier GP3® system uses replacement Rammed Aggregate Pier elements to reinforce good-to-poor quality soils, including soft to stiff clay and silts, loose to dense sand, organic sediment, and peat, as well as uncontrolled fill. By applying direct vertical ramming force to compact crushed stone, high density, high strength columns are created, providing superior support capacity, increased ...

Geopier MythBusters
Pier -supported footings transfer loads directly beneath the bottom of footing, which can put vertical loads on below-grade structures within the zone of influence. Geopier can use rigid inclusions, helical piers , or ductile iron piles in areas with below-grade structures to drop the footing loads below the bottom of the below-grade structure.





Vibro piers ® or aggregate piers are typically installed to intermediate depths of 5 to 20 feet to support new loads. Suited for light to heavy loads on large or small projects, vibro piers are quick to install and very effective at reinforcing the surrounding soil. Typical construction begins with pre- drilling the pier location to create a full-depth hole with a diameter equal to the final ...
