Vista geotechnical and environmental engineering services are designed to obtain information to develop sage, efficient and cost effective solutions to develop new projects and/or evaluate and mitigate contaminated sites. Our professional staff have worked on hundreds of geotechnical projects throughout the United States and in many other countries, ranging from tall buildings to deep excavations.

Services include:

• Development of subsurface exploration programs and associated work plans
• Preparation of laboratory testing programs and review of test data
• Bearing capacity of settlement analysis
• Soft ground engineering
• Design of low permeability barrier walls, including soil-bentonite, soil-cement-bentonite, sheet pile, and geomembrane structures
• Integration of barrier walls into low permeability surface cas
• Deep and shallow foundation design and support
• Pile design and pile installation design and implementation and evaluation of test pile programs
• Evaluation of raft foundations
• Soil-structure interation
• Design of earth retaining structures
• Recommendations for excavation bracing and support
• Earthwork design for dams and water retaining structures, including flow nets
• Rehabilitation of existing earthen water retaining structures
