Ground Conditions and Post Selection

Clay Soils: Require posts with enhanced foundation support. Concrete posts excel here, whilst timber posts need deeper installations with improved drainage. Steel posts may require concrete collaring for optimal stability.

Sandy Soils: Provide excellent drainage but may lack holding power. Concrete foundations become essential for all post types, with depth calculations based on exposure conditions and panel loads.

Rocky Ground: Often demands specialist installation techniques. Steel posts with pointed ends can be driven through moderate rock, whilst concrete posts may require pre-boring or chemical anchoring systems.

Depth and Spacing Calculations

Standard Residential Fencing: Posts typically require one-third burial depth (600mm for 1.8m high fencing) with 1.8-2.4m spacing depending on panel size and wind exposure.

Exposed Locations: Coastal or hilltop sites need increased post depths and potentially closer spacing. Our technical team provides site-specific calculations ensuring your fence withstands extreme weather conditions.

Heavy Panel Systems: Concrete gravel boards, solid timber panels, and security fencing require enhanced post specifications with deeper foundations and potentially increased post dimensions.
