Geopier -Â Densipact System for Soil Densification
The Geopier Densipact System is an innovative solution designed to enhance soil densification in clean sand profiles, particularly along coastal areas and the Great Lakes. This unique system operates without a conventional tamper or soil compaction chamber, featuring instead a series of tines attached to a base plate. Each tine is engineered to deliver energy into the soil, effectively consolidating the sand into a dense mass beneath the footing, providing significant bearing capacity. The construction process involves advancing the tines through loose sands to reach a denser bearing layer, then withdrawing and redriving to further compact the in-situ sand. Additional sand may be added at the surface to ensure the Densipact element's integrity. The system offers engineering reliability for various applications, including industrial tanks, residential buildings, educational structures, and more, demonstrating its versatility in diverse geotechnical contexts.
The Geopier Densipact system is one of our primary soil densification solutions. This system was developed specifically for clean sand profiles typically encountered along the coast and near the Great Lakes. This solution is unique in that it does not have a tamper or soil 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.
- Soil Type
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 Once the bearing layer is reached, the tines are withdrawn several feet and redriven to densify the in-situ sand in place.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.
