For a much more detailed understanding of complex geomechanic phenomena in mining or civil projects, YieldPoint offers on a research and commercial basis the world's highest resolution strain monitoring solution. This innovative geotechnical monitoring solution is based on Rayleigh backscatter of light along a single standard telecom optical fiber. Four years of intensive Research and Development have resulted in a combination of physical solutions and technical expertise that can be applied to the most complex problems in geomechanics. For example YieldPoint is able to monitor the 3-D phenomena of shear deformation in rock, not only locating the exact depth of a shearing plane along a borehole in the rock but also determining the exact direction of that movement. YieldPoint can also accurately study multiple shear situations on systems several meters in length. 2 universities, one Canadian and one american, plus the Royal Military College and a large tunnel project in Australia have already taken advantage of this unique and progressive technology.
