Screwed Injection piles

Screwed injection piles are non-displacement piles that can be used as tensile and compressive elements.The core of screw injection piles consists of high tensile steel tubular sections of the following possible diameters: 52; 60.3; 70; 82; 101.6; 133 and 168.3 mm. Varying between 200 and 450 m. Shaft diameters are formed by screw blades fitted to the first section and can vary between 200 and 450 mm. By means of rotation and the simultaneous injection of grout the soil around the core tube is mixed with grout, producing a pile shaft.  As the pile length is sectional, this type of pile can also be used in confined spaces using a smalll drill rig.  


Screwed injection piles are used as pile foundation in locations where vibrations and noise should be avoided. Using this technique, foundations can be laid in densely populated areas without causing any significant nuisance to the surrounding area. The product is specifically suitable as anchoring element for underwater concrete floors, cellar floors, pylon foundations and for renovations or upgrading foundations (particularly in confined spaces). It has a favourable pile factor. The piles can be installed at levels below ground level using a follower. 

Ambient factors

  • Can be installed in confined spaces.
  • Low vibrations and low noise.
  • Space utilisation van be easily organised.
  • The piles can also be installed at an inclination.

Pros and Cons

  • The system produces little noise and vibrations and is capable of absorbing tensile as well as compressive loads.
  • The piles can be installed in confined spaces and can be produced from ground level or from a pontoon.
