Less invasive than a traditional poured foundation, using helical piles as a foundation gains points in the USGBC's LEED rating system, making this an important green building technology. Helical Pile Sourcebook offers a practical, real-world approach to the design and installation of helical piles. With unbiased and non-proprietary coverage of the technology and available products, it reviews existing proprietary systems and discusses their pros and cons, as well as when to use helical pile technology over other foundation types. This is an essential resource for students and professionals in engineering, architecture, and construction.
