Visual Assessment

Visual Assessment

Applications

Evaluate durability or remaining life, remediation requirements
Identify cause of failure or deterioration
Determine visual condition of a structure
Map the extent and severity of visual defects such as spalling, scaling, efflorescence, cracking, delamination, patching and rust staining.

Method

Dimensions of the structure are measured using a tape measure. The walls and slabs are sketched to scale and gridded prior to an NDT investigation and this is used to record any surface defects including crack widths, location and extent of defects. Any relevant photographs are taken. Tap testing is also used to locate any delaminated areas. Inspection of joint seals is undertaken to identify defects, signs of leakage, failure or movement. This information is used to evaluate the impact these defects have on the durability of the structure.
