Performance and Applications
The performance of screw-in foundations is a result of the expertise of Engineers to interpret geotechnical information and design the foundations necessary to achieve the load capacity required.
The piles can be placed vertically or raked and can be adapted to soil conditions ranging from loose sand to clay and shale.
Difficult sites and soil conditions are accommodated by varying the size and length of the foundation being installed—making them ideal for reactive and sandy soils, or landfill sites where soil conditions may vary widely within a small area.
The screw-pile length can be single or comprise of multiple lengths joined by a special sleeving welded on site. This makes them ideal for conditions where low headroom is a problem.
In reactive soils the screw-in foundations are screwed to below the reactive clay level allowing the soil to expand and contract without any disturbance to the foundation system and the building structure.
Continuing research, testing and development has moved the use of screw-piles into many fields of piling specialisation.
Under pinning of failed buildings, domestic and commercial foundation systems, stabilization of embankments, bridge, swimming pool, light tower and re-locatable building foundations are just some of the applications that screw piles are suited to..
