Measurements and monitoring

Borehole Extensometers

The elongation / shortening of a perforation can be measured by installing extensometers with one or more bases.

The measuring bases are anchored at different depths and connected to the head with rigid rods; at the end of each rod a displacement transducer is mounted.

Sial.tec installs and manages borehole extensometers for deformation monitoring of underground excavations (tunnels, shafts, caves), quarry faces, slopes, concrete structures such as retaining walls and dams.
