VDW Piles (Cased Bored Piles)<\/h2><\/div>

VDW piles are cased bored piles installed as tight pile walls using a casing tube.<\/strong><\/h3><\/div>

Cased VDW piles enable the construction of durable underground structures even in challenging soil conditions. The casing ensures proper concrete formation in all soil types, making VDW piles an economical alternative to diaphragm walls.<\/p>\n<\/div>

  • The formation of bored piles in a casing pipe is carried out using a machine equipped with a double rotary head. During drilling with an auger, the excavated soil is brought to the surface.<\/li>\n
  • The applied casing pipe ensures stable operation of the auger and prevents excessive soil removal, providing borehole stability during drilling.<\/li>\n
  • After reaching the required depth, the concrete pile is formed in a manner analogous to the construction of CFA piles.<\/li>\n<\/ul>\n<\/div>
