L&G Engineering Laboratory performs geotechnical engineering services under the direction of licensed professional engineers. L&G owns and operates three (3) Simco HT 2800 Drilling Rigs, and one (1) Deidrich D-90 Drilling Rig which have been custom fabricated to perform TxDOT Cone Penetrometer and ASTM Standard Penetration Testing. Our drilling rigs are capable of performing solid stem, hollow stem, wet/mud rotary drilling and core drilling. All rigs are equipped with an automatic hammer for safe and accurate Texas Cone and ASTM Standard Penetration testing.

L&G’s trained and experienced engineering technicians are present during the field exploration phase of the project and collect sub-surface disturbed and un-disturbed samples, perform field tests, and observe and record the appropriate field data including soil strata and groundwater. Upon completion of the field exploration phase of the project, subsurface disturbed and un-disturbed soil samples are transported to the laboratory for testing and positive soil classification. L&G will conduct an engineering analysis after review of both the field and laboratory phases of our study. The findings and conclusions derived from our study will be prepared and presented by one of our engineers who specialize in geotechnical engineering and are familiar with the local soils and climate conditions. Our engineering report includes a boring location plan, boring logs, laboratory classification of recovered soil samples, and sub-surface water conditions. Our reports will also provide an analysis covering the general scope of the specific project, general comments and applicable recommendations regarding construction methods, sequences, and potential difficulties that may arise during overall construction as it relates to the soil and foundation aspects of the project. L&G has performed numerous small to large scale studies for the Texas Department of Transportation, Pharr District, The County of Hidalgo, Hidalgo County Pct.1 and 3, Hidalgo County Drainage District No. 1, Cameron County, The City of Mission, The City of Harlingen and various other local engineering and architectural firms. Projects performed range in size from one (1) exploratory boring to the drilling of thousands of linear feet of exploratory borings (19,000 linear feet) within a 30 day period. Major structures analyzed during these explorations include: The City of Mission Water Tower (1MG), DHS/USIBWC Concrete Flood Protection Structures (Hidalgo County), USIBWC Mission Levee Improvements, several drainage canals for Hidalgo County Drainage District #1, and lift station improvements and water/sewer line installations for the City of Mission. L&G posses the equipment and personnel to be able to quickly address any needs our clients may have.
