Geotechnical Engineering Services

Over 30 years of geotechnical engineering experience

Mosher Engineering’s Principals have over 30 years of geotechnical engineering experience with the varied subsurface conditions of the Mid-Atlantic region. This extensive knowledge provides for a wide range of geotechnical services including field explorations, laboratory testing, and foundation and site development recommendations.

Site Characterization

▪ Subsurface exploration (soil borings, test pits, probes, and rock coring)
▪ Laboratory testing of soils and rock
▪ In-situ testing (SPT, DCP, pressuremeter, dual mass penetrometer, hydraulic conductivity)
▪ Groundwater monitoring
▪ Rock quality and quantification

Engineering & Analysis

▪ Site planning and preparation
▪ Slope stability
▪ Lateral earth pressures
▪ Dynamic loading
▪ Seismic design considerations
▪ Bearing capacity and settlement for shallow and deep foundations
▪ Failure analysis and repair recommendations
▪ Value engineering and cost estimating

Building & Structures

▪ Shallow foundations (footings, mats)
▪ Deep foundations (drilled piers, driven piles, auger-cast piles)
▪ Underpinning existing structures
▪ Slab support
▪ Groundwater control and dewatering (well points, drains)
▪ Testing and evaluation of foundations during construction

Infrastructure & Civil Works

▪ Design and analysis of dams and impoundments
▪ Recommendations for design and construction of streets and utilities
▪ Pavement design and evaluation
▪ Design of Full Depth Reclamation (FDR) for asphalt pavements
▪ Scour analysis for abutments
▪ Surface water control / stream diversion (cofferdams, sheet piling)
▪ Bridges and culvert systems

Earth Systems

▪ Retaining walls, design and construction recommendations
▪ Below-grade walls and structures
▪ Excavation shoring systems (geosynthetics, geogrids)
▪ Subsurface improvement (pressure grouting, dynamic compaction, aggregate piers)
▪ Landfill and impoundment liners (geomembranes, geocomposites)
