THE GEOPIER RAMMED AGGREGATE PIERTM SYSTEM
EFFICIENT & COST EFFECTIVE SOLUTION
A patented proprietary ground improvement system that comprises a series of piers constructed of uniformly graded aggregate (or stone) installed using specialist equipment.
The piers are installed vertically in the ground in either a triangular or square grid to at least 4m depth below the ground surface. A layer of compacted gravel is then put over the top of the piers, ready for the construction of a structure.
GROUND DENSIFICATION SOLUTIONS
VIBRO
COMPACTION
A technique that compacts granular soils and rearrange the soil particulars into a denser state. The compaction is attained using depth vibrators, typically suspended from a crane or mounted on piling equipment.
How do Rammed Aggregate Piers improve the ground?
Rammed Aggregate Piers help to limit the amount and consequences of liquefaction by:
• Displacing soil laterally to densify the soil and increase soil stiffness
• Reinforcing the soil creating a stiff composite soil mass
By achieving this, the non-liquefying soil crust is thickened and stiffened to reduce the likelihood of undulations, tilt and uneven ground surface subsidence from liquefaction of the underlying soil layers.
How are Rammed Aggregate Piers constructed?
An advantage of Rammed Aggregate Piers
is that no dewatering or excavation is required
for construction. They also typically have a
short construction period.
