Defect Cause |
Defect Remedy |
Carbonation in concrete construction |
- Chemical process affecting concrete over time
- Moisture penetration accelerating deterioration
- Poor quality concrete in some post-war construction
|
- Specialist concrete repairs
- Protection of steel reinforcement
- Possible overcladding in severe cases
|
Asbestos containing materials |
- Common use of asbestos in 1950s-1980s properties
- Found in insulation, floor tiles, textured coatings
- Health risks when materials are damaged or disturbed
|
- Professional assessment of risk
- Safe removal by licensed contractors
- Encapsulation where appropriate
|
Deteriorated flat roof coverings |
- Age-related deterioration of original materials
- Poor quality flat roof design
- Limited lifespan of early felt coverings
|
- Complete replacement with modern materials
- Consideration of EPDM, GRP or high-performance felt
- Improved insulation and drainage
|
Cavity wall insulation problems |
- Inappropriate installation in unsuitable properties
- Water penetration causing insulation to become ineffective
- Thermal bridging issues
|
- Removal of wet or damaged insulation
- Remediation of cavity
- Consideration of alternative insulation methods
|
Old wiring systems |
- Original wiring systems not meeting modern standards
- Deterioration of insulation with age
- Insufficient circuits for modern appliance usage
|
- Complete rewiring to current electrical standards
- Installation of modern consumer unit with RCDs
- Proper earthing system
