Products Geotechnical Sensors

Every geotechnical design is to some extent hypothetical, and every construction job involving earth or rock runs the risk of encountering surprises. These circumstances are the inevitable result of working with materials created by nature, often before the advent of human beings, by processes seldom resulting in uniform conditions. The inability of exploratory procedures to detect in advance all the possibly significant properties and conditions of natural materials requires the designer to make assumptions that may be at variance with reality and the constructor to choose equipment and construction procedures without full knowledge of what might be encountered.Field observetions, including quantitative measurements obtained by field instrumentation, provide the means by which the geotechnical engineer, in spite of these inherent limitationsm can design a project to be safe and efficient, and the constructor can execute the work with safety and economy. Thus, field instrumentation is vital to the practice of most geotechnics, in costrast to the practice of most other branches of engineering in which have greater control over the materials with which they deal.

GaiaComm supply, install and monitor geotechincal instrumentation from Europe's leading manufacturers  of vibrating wire sensors which are used to measure strain, load, force, pressure and temperature and are universally recognised for their long-term stability within the harsh environmental often found in civil engineering construction sites. Applications include dam safety monitoring, tunnel and bridge monitoring, deep excavation and pile testing, slope stability and structural monitoring.
Additionally the company supplies products related in the ‘out of building’ part of geothermal (ground source heat) installation with a specialist range to enable contractors, particularly within the drilling industry, to take full advantage of this growing market.

A full range of products provided are the following:
