Besides reinforcing capability in the field of geotechnical engineering, geotextile structures can be also equipped with fiber optic sensors for monitoring purposes. Thus, the MuST SMARTGeoTex Fabric becomes an innovative solution that combines the benefits of using geosynthetic materials with the sensing capabilities of fiber optic for geotechnical applications and structural health monitoring.

The CONVEX-D is a digital tape extensometer which quickly and accurately measures changes in distance between two reference points in any orientation. This design incorporates several improvements compared to other convergence instruments available on the market.

The DiTeSt SMARTape II strain sensors are designed for distributed deformation (average strain) monitoring over long distances.

The NIVOLIC SG is a high-precision liquid level system designed to measure relative settlement in a multipoint system. It consists of a series of chambers connected together by a liquid line. In each chamber, a weight is suspended to a vibrating wire transducer.

The DiTeSt SMARTube combined strain and temperature sensors are designed for distributed deformation (average strain) and temperature monitoring over long distances. The DiTeSt SMARTube sensor is especially suitable for detection of ground settlements and displacements in geotechnical applications such as dams, dikes, levees, embankments and slopes.

The Profil is a digital inclinometer probe used to locate the depth and measure the lateral displacement and deformation of soil, rock and retaining structures. The probe is waterproof and entirely made of stainless steel. It is also used to determine stability of natural or man-made slopes, embankments, dams as well as deformation of sheet pile and diaphragm walls.

The multi-level vibrating wire piezometer is perfect for measuring pore pressures at various depths beneath a single surface location. It allows for quick and reliable installations because multiple PW-series piezometers are connected to a single communication cable. The multi-level piezometer provides significant advantages in terms of time, resources and cost reduction related to installation, while providing quick and reliable reading at various depths.

The DiTemp Harsh is a unique tool for the measurement of distributed temperature over several kilometers in harsh environment (from desert to arctic). It is a powerful diagnostic instrument for the identification and localization of potential problems. It allows the monitoring of local temperature at thousands locations by mean of a single optical fiber and in just one measurement. Its inherent high stability and self-referenced principle of operation, allows on-line or off-line long-term monitoring of large structures.

Geo-textile structures, beside reinforcing capability in the field of geotechnical engineering, can be also equipped with FO sensors for monitoring purposes. Thus DiTemp® SMARTGeoTex Fabric becomes an innovative solution that combines the benefits of using geosynthetic materials with the sensing capabilities of FO for geotechnical applications and structural health monitoring.
