Drilled piles - CFA technology

CFA technology is a continuous drilling of pile holes with the help of auger bit. This technology combines advantages of drilled pile without soil extraction and universality of drilled piles. The given drilling method allows installing piles in different types of soil such as dry, boggy, loose or firm soil as well as running ground such as tuff, limestone, sandstone etc. There is no impact or vibration during the operation.

Performance of operation is 400 running meters per one shift.

Price of drilling works depends upon:

  • Type of piles (applied technology, pile section);
  • Object distance;
  • Project complexity;
  • Characteristics of soil;
  • Installation depth;
  • Volume of works.

Price is calculated for each object individually on the basis of the above-mentioned factors.
