3. Geotechnical engineering uses principles of soil mechanics and rock mechanics to investigate subsurface conditions and materials, determine the relevant physical/mechanical and chemical properties of these materials. With the good knowledge and availability of geotechnical data, we can evaluate stability of natural slopes and man-made soil deposits, assess risks posed by site conditions, design earthworks and structure foundations, and monitor site conditions, earthwork and foundation construction. Over the years we have served many reputable clients to solve and provide solutions for their geotechnical issues with the excellence of our geotechnical engineering consultancy services. We have built up considerable experiences in the use of specialised software systems for geotechnical analysis. With collaborative working between ourselves and our clients in transfering informations, knowledges and experiences, we are able to deliver efficient, practical and economical solutions within strict time constraints.
