Standard Penetration Test (SPT) Equipment
Standard Penetration Test (SPT) Equipment — Geotechnical Field Testing Equipment
The SPT N-value is still the most widely reported field index for sand density and foundation design in boreholes. We supply manual donut and safety hammer sets, automatic trip hammers, trailer-mounted boring rigs, split-barrel samplers with liners, and hammer energy measurement systems. Borehole depth, drilling method and whether you must report energy-corrected N60 values decide the configuration. Kits are built to the dimensions in ASTM D1586 and BS EN ISO 22476-3, with energy checks following ASTM D4633.
Applicable standards
How to specify
- Confirm the drill rod thread type so the anvil and adaptor fit your existing rods.
- An automatic trip hammer gives far more consistent energy than a rope-and-cathead setup.
- Order spare drive shoes and core catchers; they wear quickly in gravelly ground.
