GEWI ® Pile
Advantages and Characteristics |
The DYWIDAG GEWI ® Pile is a drilled
micropile with a steel core made of
GEWI ® Bar with hot-rolled, continuous
thread deformations on both sides, the
coarse GEWI ® Thread. The
steel core is sheathed by cement grout
which acts both as corrosion protection
and load transfer into the soil or rock.
- robust coarse thread remains threadable even when dirty or damaged
- can be cut off and spliced at any given point
- excellent load transfer into concrete structures by means of anchoring elements
- a small drill hole diameter allows economic drilling equipment
- tensile, compression and alternating loads can be transferred to the same extent
- the coarse GEWI ® Thread guarantees maximum bond between steel and cement grout
- the stress-strain curve of the GEWI ® Bar shows high ductility
- continuing settlements can be stopped by preloaded GEWI ® Piles
- load transfer into the soil is optimized by the post-grouting system
- Double Corrosion Protected Piles can be used in aggressive media such as seawater or water leaking from dump sites
