GROUNDSCREW FOUNDATIONS
Design loads
Individual Pile demand loads are needed in kN for compressive, tensile and lateral loads. Typically all groundscrews are cantilever piles and share the lateral bracing demand evenly through all piles in the design. 20 bracing units = 1kN. Diagonal bracing and / or pile extensions (timber or steel posts) are available for multiple design options for high levels above ground or sloping building platforms.
Groundscrews can be used as a spot footing for post or ‘foot’ mounting. Groundscrews are a superior option for use in expansive ground conditions, especially in conjunction with concrete slab foundations. Grouped Groundscrew arrangements are available to achieve high point load. Segmental, extendable Groundscrews are available for deep ground penetration for bridging and zone of influence requirements.
