Why Monitor?

Cracks often appear in buildings and civil engineering structures. This is usually a symptom of distress within the fabric materials used in the construction. Cracks are often of little significance and can be easily repaired but sometimes they are the first sign of a serious defect which may effect the functioning and stability of the building.

Monitoring the changes in the width of the cracks over a period of time helps diagnose the cause of the cracking and determine whether it is significant.

The Survey

Structural crack monitoring can be incorporated into our subsidence investigations. The survey consists of measuring the width, length, frequency, direction and location of the cracks then monitoring them over an agreed period of time. Although we normally use the Avongard and disc monitoring techniques, we can also install deep seated datums to help record the movement of subsiding structures, which allows level monitoring to take place.
