5.3 Lateral capacity and uplift
| Local condition | Common local practice | GEOSS verification | |----------------|----------------------|---------------------| | Dense sand/gravel | Driven precast concrete or steel H-piles | Check drivability (wave equation analysis) | | Soft clay | Bored cast-in-situ (CFA or rotary) | Verify wet concrete stability & rebar cage placement | | Shallow rock | Rock-socketed bored piles | Confirm socket roughness & cleaning method | | High water table | Continuous flight auger (CFA) or driven piles | Avoid casing withdrawal issues | | Limited headroom | Mini-piles (micropiles) | Check bond length in local grout/rock | indigenous construction techniques
This article unpacks the core tenets of the GEOSS guidelines, focusing on how engineers can adapt pile foundation practices to local soil stratigraphy, indigenous construction techniques, and available materials without sacrificing safety. and available materials without sacrificing safety.
