Overview

Subsurface Moisture Detection Solutions

Talk to Our Experts

Soil moisture sensors play a critical role in monitoring the water content within unsaturated zones of the earth, offering essential insights into geotechnical stability, slope behavior, and foundation performance. These devices are especially valuable in assessing expansive or collapsible soils, managing drainage systems, and evaluating irrigation or precipitation impacts on built environments. By accurately capturing the moisture distribution across different depths and locations, these sensors help engineers and site managers make informed decisions that minimize structural risk and optimize ground performance.Geotechnical Monitoring Tools, based in Vancouver, BC, provides advanced soil moisture sensing solutions to industries across North America. As a trusted B2B company, we specialize in delivering robust systems backed by smart technology, intuitive software, and expert service that collectively support safe, efficient, and scalable geotechnical operations.

California Rail Expansion Project

During a major rail line upgrade in Central California, Geotechnical Monitoring Tools supplied a wireless soil moisture monitoring system to monitor expansive clay zones. Our sensors provided critical alerts during rain events, helping contractors delay construction during peak saturation, reducing potential slab uplift risk.

Hurricane-Impacted Levee System in Louisiana

Following increased rainfall patterns due to extreme weather, our soil moisture sensors were deployed along a vulnerable levee system. Engineers used the data to pinpoint over-saturated zones requiring reinforcement, successfully preventing floodwall failure during the subsequent storm season.

Toronto Metro Infrastructure Monitoring

In downtown Toronto, our soil moisture sensors were embedded in a subsurface excavation project to track soil drying and hydration cycles near utility lines. Alerts on soil contraction helped proactively stabilize duct banks and avoid underground service disruption.
