Don’t let subsidence ruin your home
Subsidence is a serious issue that can affect homes all around Cork. It occurs when the ground beneath a property sinks, causing the building to move and potentially crack.
The main causes of subsidence in homes around Cork
Several factors can lead to subsidence in Cork:
Clay soil: Cork sits on clay soil that shrinks and swells with changes in moisture levels.
Tree roots: Large trees near buildings can extract water from the soil, causing it to dry out and shrink.
Leaking pipes: Water from damaged pipes can wash away soil or cause it to soften.
Mining: Old mine shafts or tunnels can collapse, leading to ground instability.
Drought: Extended dry periods can cause soil to shrink, especially in clay-rich areas.
Signs and symptoms of subsidence
Spotting subsidence early can help prevent major damage. Look out for these signs:
Cracks in walls, especially those wider at the top
Gaps between walls and skirting boards
Doors and windows sticking or not closing properly
Sloping or uneven floors
Wallpaper rippling or tearing for no apparent reason
Frequently asked questions
Common questions asked from previous subsidence repair clients.
Cracks in walls are a key indicator of subsidence. Look for diagonal cracks wider at the top than bottom. Other signs include doors and windows sticking, sloping or uneven floors and wallpaper rippling at wall/ceiling joins.
The repair process starts with a structural engineer’s inspection. They’ll assess damage and recommend solutions. Common fixes include, underpinning foundations, repairing damaged walls and addressing any drainage issues.
Repair costs vary based on the extent of damage, size of property and location.
Timelines vary by repair method and damage extent. Resin injection can take just 1-2 days. Traditional underpinning often takes 4-8 weeks. Complex cases might need months of work. Your structural engineer can give a more precise estimate.
