Specialty piles are generally considered “problem solver” deep foundation systems. Many projects are faced with extensive construction constraints. Specialty piles are ideal for contaminated sites to avoid spoils, in low overhead conditions, in restricted site conditions, and on sites where noise and vibration are not tolerated. When you factor in the indirect cost of these outside factors, a specialty pile often proves to be the most economical solution on a total project cost basis.  We have three types of specialty piles:

---

TUBEX Pile

The TUBEX piles are steel and concrete pipe composite piles that are screwed into the ground under very high torque and down-pressure with an oversized tip. Tubex utilize soil displacement, the oversized pile tip increases the pile’s surface which allows for higher compression and tension capacities.

TUBEX Pile with Grout (Tubex Grout Injection)

If your project requires a higher capacity than a pipe pile will allow, the TUBEX piles with grout could be a solution. The installation of this pile uses the same equipment and process as a standard Tubex pile but as the piles are installed, a high-pressure grouting system is used to pump grout through the pile tip or grout is gravity fed from the surface to create a soil-cement grouted zone around the outside of the pipe. This increases the pile’s effective diameter without installing any more steel in the pile.

TUBEX Pile Sizes –

EDTTEX Piles

The EDTTEX piles are steel and concrete pipe composite piles that are screwed into the ground under very high torque and down-pressure using the same size drill tip as the pipe.  EDTTEX piles are also true soil displacement piles and do not generate spoils. EDTTEX piles can be installed from 8” pipe to 24” pipe.
