Screw Piling Solutions
Screw piling is a method which uses circular hollow galvanised steel pile shafts with one or more steel helices attached to them and can be installed rapidly with minimum sound and vibration disturbance. Screw piles, also known as helical piles or screw anchors, are fastened into the ground much like a screw is fastened into wood, as opposed to other piling solutions which are driven into the ground or augured and cast in-situ.
The Advantages of Screw Piles
This is an effective and sustainable method of deep foundation support as the required loads can be achieved by putting less material into the ground and taking less out. The piles cut through the ground along a constant angle rather than boring out a hole. Similarly to driven piling, savings can be made not only on timescale but by reducing both the cost of muck away and the carbon footprint of the project.
When the screw pile has achieved its required depth it will remain there and can be topped up with concrete if the design calls for it. In some instances the screw piles can be removed from the ground at a later date if necessary with less complications than other pile types.
Installation Techniques
Depending on the loads required, screw piles can be installed in a number of ways using powerful hydraulic attachments. If there is restricted access to site and the loads required permit it, smaller hand held motors can be used which is ideal for extensions to domestic projects in the city. With more space and when larger loads are required, excavators can be used to operate more robust screw piling attachments which makes this a versatile piling technique.
