GeoDetect^®

GeoDetect^® is the first sensor enabled geotextile on the market to provide soil reinforcement, structural health monitoring and an early warning system into one package. Our “intelligent geotextile” is the first system designed specifically for geotechnical applications and offers a technical solution for monitoring geo-structures for changes in strain, temperature or the combination of the two. GeoDetect^® is the only solution available on the market able to measure low strain in a soil structure. The GeoDetect^® System incorporates a geocomposite fabric, fiber optics, instrumentation equipment and software to provide a innovative solution for the multi-functional requirements of a geotechnical application, e.g. protection of the optical fiber, anchoring interface with the soil, in-plane drainage capability and reinforcement in addition to data acquisition.

GeoDetect^® comes in three product configurations:

1. GeoDetect^® is a customizable solution that is created to meet the unique requirements of each individual project. Fiber Bragg gratings (FBG), Stimulated Brillouin Scattering and Raman Scattering are all proven fiber optic technologies that can be built into GeoDetect^®. These technologies measure strain, strain & temperature or temperature only changes in soil structures. Strain as low as 0.02% can be measured with a spatial resolution of 0.5 m. With the proper software, changes in temperature can be monitored at 0.1 ^oC with a spatial resolution of 0.5 m.

2. GeoDetect^® S uses Fiber Bragg Gratings (FBG) technology to measure strain and/or temperature in soil structures. Compact and easy to install, GeoDetect^® S is 1 meter wide by 10 meters long. Two FBG optical fibers are embedded onto each GeoDetect^® S strip with 11 FBG sensors strategically inserted onto the two special optical fibers approximately 1 meter apart. Strain measurements as low as 0.02% can be obtained with a spatial resolution of 0.5m. Changes in temperature can also be monitored at 0.1 ^oC.

3. GeoDetect^® S-BR is a customizable solution that uses Stimulated Brillouin and/or Raman Scattering technology in single mode and multimode fibers to measure strain as low as 0.02% and/or changes in temperature of 0.1 ^oC with spatial resolutions of 1.0 m at distances up to 20km with suitable instrumentation. GeoDetect^® S-BR is designed for projects such as oil pipelines, levees, roads and rails.
