REI uses directionally steered holes to place your sensors and monitoring equipment in areas where traditional non-directional holes may not be able to reach. With REI’s focus on directional drilling, our team can assist developing an installation plan using steered boreholes. REI is capable of using directional techniques to install groundwater sensors and monitoring equipment, including vibrating wire piezometers, time-domain reflectometry, fiber optics, wireless piezometers, and spatial location sensors.
