Geotechnical drilling is a critical component of site development involving comprehensive subsurface investigations to evaluate soil conditions and inform engineering decisions. At Tri-State Drilling Technologies, Inc., our geotechnical services include Standard Penetration Testing (SPT) conducted in accordance with ASTM D1586 standards, which utilizes split-barrel sampling to determine soil strength and consistency. Our experienced team also performs detailed classification of soils through soil profiling to identify layers, composition, and other geotechnical properties essential for construction and design. Additionally, we offer soil percolation and infiltration testing to assess the soil's ability to absorb and drain water, which is vital for stormwater management and septic system planning. These thorough testing methods provide reliable data for safe and effective project development.
