La Joyita

Engineering Services

Our consulting approach consists of understanding the geological and geotechnical characteristics of a given project including its history, performing detailed geotechnical analyses, and applying innovative solutions for design and construction. For this, we rely on a qualified group with more than 60 years of experience in geotechnical consulting and the construction industry. This experience is combined with traditional and modern tools that provide clients with practical, safe and cost-effective engineering solutions.

Our projects cover:

  • Geotechnical studies for projects that include tailings dams, water dams, tailings dry stacks, filters, reservoirs, landfills, bridges, highways, buildings, residences, telecommunications towers, storage tanks, solar panels and wind turbines.
  • Mine closure plans.
  • Geotechnical analyses for shallow and deep foundations.
  • Settlement analyses and monitoring.
  • Geotechnical analyses for earth support systems such as retaining walls, tiebacks, soil nails, etc.
  • Soil improvement by using geosynthetics.
  • Seepage analyses in embankments.
  • Liquefaction potential evaluations.
  • Quarry explorations and stability excavation.
  • Soil and rock slope stability analyses, remediation and monitoring.
  • Evaluation of collapse potential in limestone rock (sinkholes).
  • Erosion control.
  • Inspection of dams and reservoirs.
  • Forensic geotechnical engineering.
