Design of Earth Support Systems

Value-engineered design, design-build, and third party review services for hillside developments, coastal bluffs, and property-line structures.

Earth Retention Systems (conventional walls, soldier beam and shotcrete walls, tieback or soil nail walls, secant pile walls, modular and plantable walls, hybrid walls)
Slope Stabilization Systems (dowels, caissons and grade beams, tiebacks, tiedowns, geogrids)
Temporary Sheeting and Shoring
Dewatering Systems
Ground Improvement and Grouting
Foundation and Slab Rehabilitation (jacking, injection, underpinning)

Forensic & Expert Witness Services

Landslides, bluff retreat, distressed foundations and slabs, ground subsidence, expansive soils, slope creep, vibration damage, water damage, dewatering problems, tieback problems, shoring problems, loss of lateral and subjacent support.
