Newcastle Chapter

Geotechnical Anchoring Systems and GEWI Piles

Steve Dubé, Division Engineer, DYWIDAG-Systems International

The lecturer will first present a summary of the geotechnical anchoring systems offered by DYWIDAG-Systems International using bar and strand. The focus will then be on GEWI-Piles: a minipile system that uses steel Threadbars grouted in small drilled holes. The grout body encasing the Threadbar provides corrosion protection, enables load transfer into the rock or soil, as well as stabilisation against buckling in weak soil layers. The topics covered will be: pile capacity, single and multiple bar pile design, bond enhancement using post grouting, pile head details, corrosion protection, testing methods, advantages and case studies of bridges, buildings and excavations.
