This project involved installing 6 quantity 60RL* screw piles to support a small wooden Cabin.
Screw piles were the preferred choice of foundation for two reasons, firstly as there were tree roots and secondly, the ground dropped away by up to 1meter in some pile positions.
Using our 400H hand held torque head 2 rows of 3 piles were installed with the front 3 piles being installed to ground level and the back 3 protruding above ground level by approximately 1m.
As a precaution a cross brace of the 3 rear piles was designed to be used to ensure lateral stability.
The piles were terminated with a flat 200mm x 300mm plate which allowed easy connection of the steel ring beam for the cabin to sit on.
Once installation was complete it was found that the stability of the piles was adequate and cross bracing was not required on this occasion.
A brilliant system which I wouldn’t hesitate to use in the future
*the 60RL is a light duty of the 60R, a cheaper option for low loadings, the difference between the 60R and 60RL is the tube thickness.
