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.
GEWI® Piles can also be used as Multibar Piles.
Advantages of the GEWI® Multibar:
- Small drill hole diameter
- Standard corrosion protection
- Extremely good bonding
- Screwable due to the coarse GEWI® Thread
- Easy installation and grouting
