What Does SPT Stand For?

SPT stands for Standard Penetration Test

SPT, or Standard Penetration Test, is a geotechnical soil testing method used to evaluate the subsurface conditions of soil at a specific site. It involves driving a split-spoon sampler into the ground using a standardized drop weight and measuring the number of blows required to penetrate a set depth. The data collected provides valuable information on soil consistency, density, and potential bearing capacity, which is essential for foundation design and construction planning. SPT results are commonly utilized in various civil engineering and environmental projects.
