Drilled micropiles for drilling in difficult ground conditions
The micropiles may be drilled through all natural soil layers all the way into bedrock, with small deviations in position and inclination.
RD® micropiles are delivered either as pipes or as ready-made elements with threaded heads.
RD® micropiles are spliced either by an external threaded sleeve or by welding. The advantages of a threaded sleeve are:
The design is CE marked and meets all technical requirements for micropile splices. The tensile strength of a splice is guaranteed to be 50% of the compressive strength of the micropile.
