    The effectiveness of geogrid reinforcements can be monitored using displacement transducers attached to the grid with requisite clamps. Networks of such transducers, connected to data acquisition systems, can help identify areas of subsidence and forewarn of impending failures. As geogrids are generally designed to accommodate high strains, it is important to select transducers with appropriate range and optimum sensitivity, and the clamps which attach the transducers should be designed such that they do not weaken (or stiffen) the grid. Cover plates are used to protect the transducers from overlying aggregate and fill. Horizontal extensometers, pressure cells and settlement profilers are also commonly used in reinforced embankment constructions.
