Maintenance and Diagnostics
Structural sealants should also be checked during maintenance and cleaning works for signs of deterioration and allowing possible entry of water and air.
Diagnostics of Defect
Visual Assessment
Visual assessment of the curtain wall during rainy days may locate the areas where water will penetrate.
Thermography
Water penetration can also be investigated with Thermography using a thermo tracer.
Fibrescope
The building structure can also be checked for movement to reveal areas that are stressed and causing cracks or gaps to appear. This can be done by inserting probes of the Fiberscope to inspect connecting condition behind external cladding wall of a building.
Elastic Recovery Meter
In the case of sealant failure, an Elastic Recovery Meter can be used to check for its effectiveness.
