The purpose of geotechnical investigation is to evaluate and characterize the subsurface conditions of a project site, including topography, geomorphology, geological structure, engineering geological conditions, physico-mechanical properties of soils and rocks, and hydrogeological characteristics. The investigation provides essential technical data for the design and construction process, enabling the selection of safe, economical, and technically appropriate engineering solutions for each project.

HAI (LAOS) Survey & Construction Sole Co., Ltd provides comprehensive geotechnical investigation services for infrastructure, industrial, commercial, hydropower, and transportation projects throughout Laos. Our investigations are carried out in accordance with recognized technical standards and international engineering practices to ensure accurate, reliable, and efficient results.
