In our 25 years of service we have worked on the islands of Puerto Rico, Hispaniola, US Virgin Islands, Cuba and the Lesser Antilles, and most recently in the Republic of Niger, Africa. As geotechnical engineers, GeoConsult has performed numerous subsurface investigations and analyses for buildings, roadways, dams and levees. GeoConsult has participated in the design of dams and flood retention dikes or levees. We have donducted numerous extensive subsurface investigations for varied infrastructure projects using auger borings with SPT, cone penetrometer tests (CPT), seismic refraction and soil resistivity, and crosshole seismic analyses. Solutions have included deep and shallow foundations, micropiles and tiebacks. GeoConsult has designed several deep excavations where dewatering was a major concern. We have reviewed ground conditions that required improvement using various inclusion techniques. Site specific seismic analyses have been performed by various clients and situations. Most importantly, GeoConsult has demonstrated an ability to meet demanding schedules. This page presents a brief description of some of our relevant projects.


Bridge over PR-18 in San Juan. Vertical cut (11.5 meters, 38 feet) using soil nails along existing bridge for construction of new bridge abutment.

Geotechnical characterization and design recommendations for the San Antonio Tunnel.

Dewatering and excavation designed by GeoConsult for 12'-deep excavation in sand with lower clay basement, San Juan, P.R.

View of 15-foot excavation within highly congested treatment plant, dewatered using single interior sump pump and gravel mat with H-piles and wood lagging.

Excavation next to Atlantic Ocean in Isla Verde, Puerto Rico - dewatered using combination trench drain and wellpoint system. Note wood lagging retention system.

48-foot-deep excavation in soft alluvial soils - excavation considered possibility of blowup due to artesian pressures in lower calcareous deposits.
