The Geopier RAP system for ground improvement
By Mark Tigchelaar, P. Eng., GeoSolv Design/Build
Ground improvement techniques have become more widely used in Canada over the past decade and owners, developers, contractors and engineers have gradually taken notice of the unique advantages offered by using ground improvement techniques. Of the many ground improvement techniques used in Canada, few have been employed more often than the Geopier Rammed Aggregate Pier® (RAP) system. Since 2006, many thousands of linear kilometres of Geopier RAP elements have been installed in Canada to support industrial, commercial and residential projects, and other applications such as liquefaction mitigation, embankment and wall support, and other structures. Since its introduction in the U.S. over 30 years ago, the Geopier RAP system reinforces a wide variety of soil types including undocumented fill, loose sands, soft/sensitive clays, silts and trapped organics to provide increased bearing capacity and engineered settlement control.
Expander Body International is setting out to fundamentally change the way we think about foundations
By Paul Adair
The installation of deep foundations has not changed much over the last half century. While there have been tweaks and adjustments to the technology, generally speaking, there are only two different types of piles primarily used today to hold up buildings: end-bearing piles, in which the pile is driven into the ground until it hits bedrock or other bearing materials, and shaft-bearing friction piles, in which the pile generally mobilizes more resistance the deeper it is installed. Ottawa-based Expander Body International (EBI) is setting out to provide a third option and fundamentally change the way industry thinks about foundations.
