Everyone knows that high capacity spread footings are the most-cost effective foundation system, when they can be employed. High capacity footings can only really be designed for relatively high quality sub-foundation soils, and it is the approach of choice for the glacial till that blesses much of the province of Ontario. Owners and developers today are challenged by the low supply of high-quality sites. The leftover sites often have less-than-adequate soils for spread footings.
Traditional approaches in the province, and certainly across Canada, to deal with less-than-adequate sub-foundation soils generally have been limited to a few options up until about 15 years ago:
Today, ground improvement is widely used as cost-saving option for situations where regular spread footings are not possible. Ground improvement is a “work smart, not hard” approach for treating challenging soils throughout Ontario.
To truly appreciate the theory, methods and development behind ground improvement, it is essential to understand its origins. This talk aims to demystify the early beginnings of ground improvement and cover it’s short, but very rich history in Ontario including the introduction of mainstream ground improvement in 2006 to the province. This presentation will also engage attendees by citing various eye-opening case study’s featuring some of the most complex projects to date throughout Ontario with compelling data gathered on site. Attendees will also benefit from gaining an appreciation for the ongoing innovative technologies and methods that are continually emerging in the ever-growing field of ground improvement.
