What is a Ground Investigation Testing Machines / Soil Investigation Equipment?

Ground investigation testing machines are specialized instruments used to assess the strength, stability, and characteristics of soil before construction projects. These tools help engineers and architects design safe and efficient foundations based on reliable subsurface data. Common machines include the SWS tester (Screw Weight Sounding), ideal for small-scale constructions, and the SDS tester (Screw Driver Sounding), which enables more accurate measurements of soil strength with minimal noise and vibration—perfect for urban environments. More advanced systems like GeoKarte® IV allow real-time analysis of subsurface changes, aiding in liquefaction risk assessments and soil improvement decisions.

By using these machines, builders can prevent future issues like settlement or foundation failure. Selecting the right testing method depending on the site’s condition is crucial to ensuring safety and cost-efficiency.

Application of Ground Investigation Testing Machines / Soil Investigation Equipment

✅ Pre-construction soil survey for residential housing
SWS testing is used to assess soil bearing capacity before building homes.
✅ Low-noise testing in urban or sensitive areas
SDS testers are ideal for use in narrow city plots, near schools or hospitals due to low noise and vibration.
✅ Detailed soil profiling for public infrastructure
Projects like roads or bridges use GeoKarte® IV to get real-time stratigraphic data before construction.
✅ Post-soil improvement verification
After ground improvement, SDS tests are conducted again to verify stabilization effectiveness.
