Geotechnical engineering services provide design and construction criteria for foundations, earthwork, pavements, floor slabs, retaining walls, seismicity, slope stability, and subsurface drainage.  Geotechnical engineering involves evaluation of most anything that contacts earth materials, primarily soils, rock, and groundwater, including: 

  • Shallow foundations such as spread footings and mat slabs for buildings, bridges, walls, towers, tanks, dams, equipment pads, vaults, and more; 
  • Deep foundations including drilled shafts, driven piles, helical piles, and micropiles;  
  • Ground improvement and rigid inclusions by stone columns, compaction grouting, rapid impact compaction, rammed aggregate piers, and deep dynamic compaction; 
  • Drainage works including stormwater biofiltration swales, infiltration galleries, horizontal drains, wick drains, and foundation drains; 
  • Rigid concrete, flexible asphalt mix, gravel-surfaced, geosynthetic-reinforced, and cement-treated pavements to support airfields, local roads, highways, heavy haul roads, and pedestrian paths;  
  • Tunneling to under-cross rail lines, roads, water bodies, and buildings; and, 
  • Landslides, embankments, earth dams, slopes, and retaining walls.
