Section 1 : Introduction
Embedment Strain Gauges were developed by the British Transport & Road Research Laboratory to
measure the internal strain in concrete structures. These waterproof gauges were developed in
conjunction with Imperial College, London and incorporate the latest materials and techniques to make
these gauges suitable for use in hostile conditions.
The nature of the instrument dictates that it is used to measure changes in strain (i.e. change in
length per unit length).
The gauges are designed for use in installations where they are cast directly into the mass of the
concrete structure. The pre-casting of the gauges into briquettes is recommended only where it can't
be avoided.
