Instrumentation

Agapito Associates, Inc. (AAI) maintains a field crew with drilling capabilities to install rock instrumentation.

AAI also provides consulting to recommend effective instrumentation programs to monitor rock movement and stress changes.  We can install instrumentation to monitor groundwater and gas pressure changes from surface or underground boreholes.

AAI maintains an exclusive distribution rights with Rock Mechanics Technology (RMT) and is  an authorized RocTest-Telemac (RocTest) integrator, offering instrumentation expertise and installation services.  RocTest is a world-leading manufacturer of Vibrating Wire and Fiber Optic high-precision measuring instruments.

AAI has the expertise and experience to design and install BPCs (borehole pressure cells), vibrating wire instruments, fiber optic instruments, inclinometers, sagmeters (tell-tales), soft inclusion stress cells (SISCs), stress measurements, extensometers, TDR (Time Domain Reflectometry) cables and piezometers.  AAI maintains data loggers and read-out equipment for a wide variety of instrumentation and is capable of installing instrumentation to meet MSHA’s requirements in gassy mines.

We maintain drilling equipment for drilling holes for instrumentation installations in underground and surface locations.  AAI’s equipment is capable of drilling up to 600 feet in horizontal, vertical, and inclined holes using electric, diesel, or pneumatic power sources.

Borehole Pressure Cells
AAI geologist installing borehole pressure cells (as many as three BPCs are installed in one borehole). Each BPC is set to a specified depth, oriented, and then pressurized before the next one is placed into the borehole.
