Tensionless Piers ease construction of wind tower foundations

摘要

One fast-growing field of industrial construction that is subject to many of these mass concrete challenges is wind towers. The foundations supporting these towers have to anchor the masts securely and resist huge overturning forces. Thermal cracking has sometimes been a problem in traditional gravity spread foundations formed of massive concrete, but a Bakersfield, Calif., firm has developed an alternative foundation design that's on its way to becoming the industry standard, with more than 5000 installations mostly in the United States and Canada.
