Krinner Ground Screws

About Krinner Ground Screws

Krinner is a family-owned company from Straßkirchen in Lower Bavaria, Germany, operating as KRINNER Schraubfundamente GmbH. Founder Klaus Krinner began developing ground screws as a concrete-free foundation method in 1994, and the company is now run by the second generation. The company says it works with 55 partners in 37 countries and lists production sites in Germany, the Czech Republic, Bulgaria, Canada and the United States.

Ground screws are galvanized steel foundation elements with a helical thread that are screwed into the soil to carry compression, tension and lateral loads. In North America the brand is marketed through Krinner North America, with the entity Krinner Foundation Systems listed as the evaluation report holder in Houston, Texas. Applications named on the site include solar systems, fencing, signs, railway and traffic infrastructure, containers, timber construction and home projects.

Products are sold and installed through a network of sales partners and specialist installers rather than directly by the manufacturer in most areas.
