Why age matters: houses from the early 1970s and before usually have clay drains with open joints. Leaking drains wash out and soften the ground under the footings, and they're behind most of the subsidence in Irish houses. Newer houses have sealed plastic drains, and were built to the Building Regulations, which include requirement A2 on ground movement.
Ground
The ground in Waterford
- Waterford has rock close to the surface in the Comeraghs and Knockmealdowns, glacial till across the lowlands, and soft ground along the Suir estuary.
- Older houses in Waterford city have the clay drains that cause most subsidence, so the drains are checked first.
- Geological Survey Ireland keeps a national landslide susceptibility map and a database of karst features. They're broad guides to an area, never a verdict on one house.
These notes describe the county in general. They're background for a conversation with an engineer, never a verdict on one house.
Schemes
Pyrite and defective blocks in Waterford
Co. Waterford isn't a Pyrite Remediation Scheme or Defective Concrete Blocks scheme area. If floors are cracking from below, or blocks are crumbling, it's a different problem from subsidence, and underpinning won't fix it.
