Contract Geotechnical/CME Laboratory
The same laboratory testing operations that ETTL performs to determine physical properties of soils and aggregates when carrying out geotechnical and construction materials engineering projects for its clients are also available on a contract basis.
The modern equipment, capabilities and staff that ETTL has for carrying out soil/aggregate testing are second to none in our service area, allowing us to offer effecient turnaround times and quality results. ETTL's geotechnical/CME laboratory is AASHTO (R18) accredited and is also US Army Corps of Engineers (USACE) certified.
