GEWI® Pile
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.

GEWI® Pile

Advantages and Characteristics

  • 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

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.

Standard Corrosion Protection

 

Double Corrosion Protection

The GEWI® Bar at the core of the pile is normally sheathed by an at least 20 mm thick cement grout layer. The high pH-value of the cement grout surrounds the steel with an alkaline medium which passivates the steel surface. The Standard Corrosion Protection is durable for compressive loads. For tensile loads, the GEWI® Bar in a corrugated sheathing is injected at the shop. The Double Corrosion Protected GEWI® Pile can be installed as easily as the GEWI® Pile with Standard Corrosion Protection. The Pile load is transferred into the unterground over the full length through the ribs of the corrugated by the exterior cement grout.
