Geotechnical Engineering

The impact of Geotechnical Engineering reaches far beyond simply identifying what kinds of soil and rock are present at a project site. The geologic conditions of a project site can widely vary even across short distances, and if overlooked these conditions can have costly outcomes on project design and construction. Arias understands that our services are a vital component of site preparation, foundation design, and overall project design; without it, a project is susceptible to cracking and other deformations as a result of improper settling and even total failure.

Geotechnical engineering services involve exploration of the subsurface, laboratory testing of subsurface samples, engineering analysis, and development of recommendations for various types of projects. Arias' licensed geotechnical engineers and engineers-in-training have diverse project experiences with earth materials including soil, rock, and groundwater. Arias’ Professional Engineers each have 4 to 50+ years of experience providing Geotechnical Engineering services. Our team is experienced, responsive, and credentialed, sees the big picture and strives to assure that our services contribute positively to both the project’s short-term and long-term performance.

Subsurface Exploration Programs, Expansive Soil Mitigation Recommendations, Laboratory Testing, Ground Improvement and Soil Modification, Subgrade Evaluation, Plan and Specification Review, Groundwater Studies, Foundation Analyses, Retention System Analyses, Pavement Evaluation, Forensic Evaluation and Recommendations, Local and Global Stability Analyses, In Situ Testing and Observation, and Materials Evaluation.

Geotechnical Engineering Services

Testimonial Image

pavement evaluation & recommendations

We provide pavement evaluations for TxDOT, city, county, and airfield pavement using coring/boring data, laboratory test results, Ground Penetrating Radar(GPR) and Falling Weight Deflectometer (FWD).

Testimonial Image

Local & Global Stability analysis

Our Professional Engineers perform local and global stability analyses for retaining walls and slopes using USA Corps of Engineers (USACE), Texas Department of Transportation (TxDOT) and AASHTO guidelines.

Testimonial Image

Materials Evaluation

Our in-house Texas laboratories provide materials evaluations for project construction materials. Laboratory test results are reviewed by the Laboratory Director and approved by a Professional Engineer.  

Testimonial Image

forensic evaluation & recommendations

Our Professional Engineers perform forensic evaluations by reviewing the as-built drawings, subsurface information, laboratory test results, piezometers, inclinometers and geophysical data. Recommendations are developed after thorough review of the gathered data and comprehensive engineering analyses.  

Testimonial Image

retention system analysis

Our team performs retention system analyses using limit equilibrium software. In addition, wedge analyses and Lpile analyses are performed as needed for the soil/rock nail walls and drilled shaft walls.

Testimonial Image

foundation analysis

Our team provides engineering analyses to determine the feasibility of foundation type, develop design and installation recommendations of cost-effective foundation system considering the subsurface conditions, geology, axial and lateral loading.  

Testimonial Image

Groundwater studies

Our team provides groundwater studies by performing field exploration drilled borings and installing piezometers. Both standpipe and vibrating wire piezometers are considered depending on the scope of the project.  

Testimonial Image

plan and specification review

Our Professional Engineers perform plan and specification reviews prior to starting construction on any project. Field Technicians are assigned according to the project specifications and requirements.

Testimonial Image

Subgrade Evaluation

Subgrade evaluation is performed by experienced and certified Field Technicians prior to construction and approved by Arias’ Professional Engineers.  

Testimonial Image

Ground Improvement & Soil modification

Arias provides recommendations for ground improvements and soil modifications based on the established service ability requirements of the project. Based on the information gathered during subsurface exploration, advanced laboratory testing, and engineering analyses; recommendations are developed by experienced Professional Engineers to reduce settlement and increase bearing capacity of grade supported structures, retaining walls and embankments.
