Bored piles / drilled shafts

Bored piles are a type of deep foundations, which involves the execution of cylindrical holes followed by the installation of a reinforcing frame and filling with a concrete mixture.

The main advantages of such piles are:

• the ability to care significant vertical and horizontal loads;
• a wide range of choice of pile diameter;
• minimal foundation settlement;
• absence of vibrations during installation.

Bored piles are widely used under the following conditions:

• buildings with significant vertical and horizontal loads;
• building foundations with significant moments;
• execution of retaining walls and protection of pit sides;
• construction close to existing buildings.

Cylindrical holes are drilled to a specified depth using special construction equipment. If the hole requires support to remain open, casing pipe or clay fluid are used. A reinforcing frame is mounted in the hole, along its entire length. Next, the hole is filled with concrete.
