Structural Damp
Structural damp refers to the presence of unwanted moisture within the structure of a building, which can compromise its integrity and lead to various problems. There are three main types of structural damp: rising damp, falling damp, and penetrating damp. Each type has distinct causes and requires specific solutions.
Rising Damp
Rising damp occurs when groundwater rises through the walls and floors of a building by capillary action. This type of dampness is commonly found in older buildings with inadequate or damaged damp-proof courses (DPC).
Common Causes:
- Lack of a proper damp-proof course (DPC)
- Damaged or deteriorated DPC
- Poor drainage around the building
Solutions:
- Installing a new damp-proof course
- Repairing or replacing the existing DPC
- Improving site drainage and ground levels
Falling Damp
Falling damp happens when water from above, such as rainwater, penetrates the building structure. This is often due to issues with the roof, gutters, or external walls.
Common Causes:
- Damaged or blocked gutters and downpipes
- Cracked or missing roof tiles
- Poorly maintained external walls
Solutions:
- Repairing or replacing damaged roof components
- Clearing and maintaining gutters and downpipes
- Applying water-resistant coatings to external walls
Penetrating Damp
Penetrating damp occurs when water penetrates through the walls from the outside. This is typically due to defects in the building’s external envelope, such as cracks, porous walls, or faulty windows and doors.
Common Causes:
- Cracks in walls and mortar joints
- Porous bricks or stonework
- Faulty window and door seals
Solutions:
- Sealing cracks and repairing mortar joints
- Applying water-repellent treatments to external walls
- Replacing or repairing faulty window and door seals
