Alhoty

Geotechnical Instrumentation and Monitoring

Groundwater levels and groundwater pressure are important ground characteristics to know before and throughout any ground excavation, construction projects, and pipeline or cable installations and more.  Alhoty offers solutions pertaining to conventional manual measurements or continuous automatic recording.  Alhoty’s instrumentation and monitoring services also includes monitoring retaining walls, ground settlement, infrastructure, and buildings continuously to provide insights into settlement over time.
