Micropiles of Full Thread Bars
Updated: 07.05.2026
Advantages and Characteristics
The SAH pile is a drilled micropile with a steel core made of the SAH bar with hot-rolled, continuous thread deformations on both sides, the so called SAH thread. The steel core is mantled 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 various anchoring elements
- A comparatively small drill hole diameter allows the use of economical drilling equipment
- Tensile, compression and alternating loads can be transferred to the same extend
- The coarse SAH thread guarantees maximum bond between steel and cement grout
- The stress-strain curve of the SAH bar shows high ductility
- Continuous settlements can be stopped by using preloaded SAH piles
- Load transferred into the soil is optimized by the post-grouting system
- Double corrosion protected piles can be used in aggressive media such as sea water or water leaking from dump sites
