The use of wind energy in Ontario has been steadily increasing, and multiple farms of a few to hundreds of wind turbines are being constructed at any given time in Ontario. The need for high stiffness foundations due to large overturning moments, and therefore, large edge pressure acting on the base of the foundation can prove challenging when soft or compressible soils at the turbine site do not provide adequate bearing capacity. The use of Geopier® Intermediate Foundations® has been used to provide increased bearing capacity and foundation stiffness for hundreds of wind turbine foundations around the world.
