Helical Piers and Engineers
Welcome to the Engineers section of our website. Our objective for this section is to provide as much useful technical information as we can for engineers and architects who are interested in designing projects with helical piers as deep foundation or anchoring solutions. As you can see, currently we have a substantial technical library that includes listings of technical papers written on helical piers in various applications, a listing of the patents awarded for helical piers, information on building code certifications, and information on basic helical pier design elements.

A certain percentage of all foundation repairs involve reinforced concrete foundation slabs-on-grade that require lifting, replacement, or void filling. The use of closed cell polyurethane foam is an improvement over the use of piers and slab brackets, mud jacking, or slab replacement.
