ETTL Geotechnical Engineering Services
ETTL has TxDOT Precertification in a number of key areas. Click here to see listing.
ETTL's professional civil engineers, engineering geologists and other experts are at the service of its clients to carry out a great variety of physical geotechnical services, as well as for consultations, engineering evaluations, monitoring of vendor contractual performance, and a wide range of special studies. Architects and builders of a substantial percentage of the major buildings in the Tyler area have called upon ETTL over the years for geotechnical engineering services (and construction materials engineering services as well) as have architects and builders in Longview and many other communities in East Texas and adjoining areas and states. 
At right, ETTL engineers, during a geotechnical study, log readings as loads are applied against a test pile APG-cast in a difficult stratum of loose wet sand. The object was to learn what pile length would be best for some 140 cast-in-place piles to be used to support a new manufacturing plant addition.
