System Description

GEWI^® - Piles

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^® (grade 75 or grade 100 THREADBAR^®) 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.

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.
