Diagnostics of Defects
Visual Inspection
- Check the nature of rendering, its strength and adherence to the brickwork.
- Check the type of bricks. Examine the layers of rendering immediately in contact with the brickwork and also the surface of the bricks for signs of whitish crystals or whitish deposits. In cases of doubt analyses should be made of any deposits, of the rendering and the bricks.
- The composition of the rendering should be checked from specification.
- A comparison should be made of the position of the cracks in the rendering with any cracks in the walls.
Thermography
Thermography can be used to determine presence of water beneath the wall that contribute to the efflorescence. In addition, fine cracks can also be captured by this equipment.
