GEWI® Piles

GEWI® - Piles

System Description


The GEWI® Pile represents the consistent development towards minimizing the diameter while maintaining a high bearing capacity. It convinces by its simple design. Core of the pile is the GEWI® with hot-rolled continuous thread deformations on both sides, the coarse GEWI® Thread. The grout body encasing the steel provides Standard Corrosion Protection, enables the force transfer into the rock or soil and stabilizes against buckling in weak soil layers.

The GEWI® Pile system is also very suitable to be used as Micropiles. The GEWI®-Coupler Splice allows splicing of the GEWI® Bar at any point and the reconnection of the micropiles to piles as long as necessary.

GEWI® - Pile - System Description
The GEWI® Pile combines a multitude of advantages
  • The small drill hole diameter allows economic drilling methods. Drilling through hard obstacles and bonding rock is easily accomplished.
  • The stress strain curve shows high ductility at high strength required for shear deformations and seismic loads.
  • Compression and tensile loads, also alternating loads, can be transferred into the underground by skin friction along the grout body.
  • Compared to conventional drilled piles, the GEWI® Pile has a greater elasticity. A combined load transfer by GEWI® Pile and foundation slab may be chosen when the economic conditions so warrant.
  • Continuing settlements of a structure can be stopped by preloading GEWI® Piles.
  • The GEWI® Bar as a centrically located bearing element allows the installation of a Double Corrosion Protection System, unique in the pile technology.
  • The coarse GEWI® Thread guarantees maximum bond between GEWI® Bar and cement grout with uniform bearing behavior.
  • The continuous coarse GEWI®-Thread allows GEWI® Anchorages and GEWI® Splices at any given point.
