RADIX Extendable Screw Piles

Low-carbon foundations capable of reaching load-bearing depths

RADIX Extendable Screw Piles offer an efficient method for raising ground levels without extensive excavation and ensure that foundations are installed to the required depths to achieve maximum load-bearing capacities in areas of soft ground.

Screw piles are galvanised per BS EN ISO 1461:2009 for long-lasting protection and increased life expectancy. Engineers' certificates and documentation are available upon request.

Applications: Solar arrays and battery storage, holiday lodges, house extensions, modular construction, temporary structures, and more.
