Our Geotechnical Services
We offer the following geotechnical services
|
|
Soils and Foundation Investigation
Soil and foundation investigation include soil borings, test pits, CPT soundings, using truck-mounted, track-mounted and portable drilling rigs. Samples are tested in our own or outside laboratories, and then design and construction recommendations are prepared as a signed document for use by the design team, and for submittal to the building Department.
Foundation Evaluation
Foundation evaluations include determination of the best and most cost effective foundation types and depths, repairs, or underpinning of existing foundations where appropriate.
Drainage Consultation
Drainage consultation results in solutions for wet basements and crawlspaces, and hillsides.
Paving Design in Asphalt, Concrete, and Pervious Materials
Paving design in asphalt, concrete, and pervious materials include pavement thickness design, and recommendations for new pavements or restoration of existing paving.
Slope Instability, including Landslide Repair Engineering
For slopes, we investigate the stability or instability of slopes, and develop solutions, including using computer slope stability programs for analysis and development of remedies for stabilizing movement. These may include borings, instrumentation, monitoring, drainage improvement or structural repairs.
Earth Retention Systems
Earth retention systems include analysis and design of mechanically stabilized earth and segmental block retaining walls, including “big blocks”.
Construction Observation and Testing
Construction bservations and testing for grading, earthwork and reinforced soil, foundation pier drilling, helical piles, conventional tiebacks and ground anchors. Including specifications and building code compliance, with reporting to governmental agencies.
Litigation Support
We provide consultations related to mediation of lawsuits on geotechnical-related issues in the areas above.
