Defect Category
Waterproofing & Water Ingress
Technical guidance covering waterproofing membrane failures, water ingress pathways, rising damp, penetrating damp and related remediation for balconies, roofs, basements, podiums and façades in Class 2 buildings.
Balcony Waterproofing Failure
Failure of balcony waterproofing membranes at junctions, penetrations and field areas causing water ingress to the structure below.
Roof Waterproofing Failure
Deterioration or failure of roof waterproofing systems resulting in leaks, membrane delamination and structural water damage.
Planter Box Waterproofing Failure
Waterproofing failure in planter box construction causing moisture migration, corrosion of reinforcement and substrate deterioration.
Basement Water Ingress
Water ingress into basement and substructure areas driven by hydrostatic pressure, joint failures and waterproofing membrane defects.
Podium Waterproofing Failure
Failure of podium deck waterproofing systems under trafficable and landscaped areas causing water penetration to car parks and occupied spaces below.
Rising Damp
Capillary rise of moisture through masonry, concrete and substructure elements causing internal finishes deterioration and salt efflorescence.
Penetrating Damp
Lateral moisture penetration through external walls, masonry and façade elements driven by driving rain, failed sealants and porous substrates.
Façade Water Ingress
Water ingress through the external building envelope via failed cladding junctions, render cracking, window perimeter failures and unsealed penetrations.
Failed Screeds & Tile Delamination
Drummy, cracked or debonded tiles on balconies and podiums caused by failed screeds, trapped moisture, poor falls and membrane failure beneath the tile finish.
