Screw PilesFLI Screw Piles
FLI Structures are leaders in the design, manufacture, supply and installation of Screw Piles and Steel Grillages. This is a steel foundation solution suitable for Railway, Highway, Construction, Telecoms & Civil structures, including Portal Gantries, Cantilever Gantries, OLE, Signal Posts, Platforms, Masts, Towers, CCTV, Lighting Columns and Sign Posts, etc.
FLI Piles will support structures in both tension and compression providing an ideal solution where overturning moments are significant.
The piles are individually designed by our engineers to suit the separate ground conditions on the site. The torques are recorded during installation to confirm that adequate capacity has been achieved. Testing can be done simply, if required.
About Screw Piles
Screw piles were invented by Alexander Mitchell & were first used in the 1830’s to support lighthouses and piers. Initially, they were made from cast iron. In 1863, Screw piles were used to support Brighton pier. The technology has been widely used in America and is now becoming popular within the UK.
Today, screw piles are made from galvanised steel. They are suitable for both tension and compression loads. In many cases the piles and the associated structure can be installed in a day.
The piles are individually designed by our engineers to suit the separate ground conditions on the site. The torques are recorded during installation to confirm that adequate capacity has been achieved. Testing can be done simply, if required.
Benefits of FLI Screw Piles
- Quick to install – saving time & money
- No excavations or spoil to cart away – saving money, particularly if there is contaminated ground
- No concrete or curing time – enables speedier commissioning of sites
- Small footprint – enables smaller bases in restricted areas
- Flexible design - frames can be designed to bridge services allowing area congested services to built negating the need for re-routing cables.
- Sustainable solution – are removable & re-useable.
- Installation in low temperatures – no down time, unlike concrete
- Cost effective solution in soft ground, where traditional piling is more expensive and concrete is technically unsuitable
