- Ideal for building foundations on clean sand soils
- Rapid installation (schedule savings)
- 20-50% savings versus deep foundations and over-excavation
- No spoils and haul-off costs
The Geopier Densipact® system is one of our primary densification solutions. This system was developed specifically for clean sand profiles typically encountered along the coast and near the Great Lakes. This system is unique in that it does not have a tamper or compaction chamber, rather it is composed of a series of tines connected to a base plate. Each individual tine imparts energy into the soil, densifying the sand to create a raft of very dense material directly beneath the footing. This system is unique in that creates a mass of dense sand rather than distinct aggregate pier elements.
- Clean sand soils (fines content less than 15%)
Geopier Densipact® piers are constructed by advancing the patented tines through loose sands to a denser bearing layer. Once the bearing layer is reached, the tines are withdrawn several feet and redriven to densify the in-situ sand in place. This process is repeated up to the ground surface. Additional sand material can be added at the ground surface (as needed) to make sure there is adequate material to construct the Densipact element.
