In places to which access is difficult and precast piles cannot be installed, e.g. due to restricted movement of heavy equipment, or piles are to be installed at an angle of more than 30-35 degrees, we offer the installation of a variety of micropiles in accordance with the code PN-EN 14199 Wykonawstwo specjalnych robót geotechnicznych. Mikropale (Execution of Special Geotechnical Works. Micropiles).

We install micropiles drilled with continuous flight auger, continuous flight auger in tube casing, the CFA technology or self-drilled hollow bars and any micropiles driven with 10-90kN hammers.

Depending on design requirements, soil conditions and technologies, we install palisades without injection, with primary and/or secondary injection, as well as multiple, general and selective injections. Micropiles are reinforced with self-drilled hollow bars, tubes, steel section or bars. In case of permanent micropiles installed in aggressive soil conditions we apply the required excess materials or reinforcement with double corrosion protection.

For technical specifications (SST) regarding the execution of micropiles, please visit the site of the Polish Association for Special Foundations Contractors (Polskie Zrzeszenie Wykonawców Fundamentów Specjalnych).
