Twist Screw Piles

Twist Screw Piles is the screw pile brand of TWIST Developments Inc., a manufacturer based in Leduc County, Alberta. The company says its piles were developed with field studies and testing by the University of Alberta's Department of Civil Engineering.

Its website states that TWIST's screw piles hold a CCMC (Canadian Construction Materials Centre) evaluation number and that the evaluation report is available on request. The site also notes completion of SECOR safety certification. Besides piles, it lists accessories and a Become an Installer program, and it recruits Twist Certified Installers in Southern Alberta who have their own machinery. Its marketing focuses on engineered piles for demanding conditions.

Contractors, engineers and builders can call 1-855-562-8625 for product information. Homeowners should ask Twist which certified installers work in their area, then confirm with the installer which pile model is proposed, how torque is verified, and what documentation will be provided for the permit.
