−0.2 mm/yearLittle to no ground movement
What is it?
How many millimetres the ground here sinks or rises per year. A minus means the ground is sinking. It is an average over a square of about 50 by 50 metres, not a measurement of this home's foundation.
Why does it matter?
Sinking ground can cause cracks in walls, sticking doors, and subsiding gardens, paths and pipes. The greatest risk is to an older home without piles or on wooden piles, in an area with peat or clay. It is mainly uneven sinking that damages a house; this map shows the pace in the area, not how evenly it happens.
Levels
- Ground rising> 1.5 mm/year
- Little to no ground movement−1.5 to 1.5 mm/yearNow
- Limited subsidence−5 to −1.5 mm/year
- Strong subsidence−10 to −5 mm/year
- Very strong subsidence≤ −10 mm/year
Where do these limits come from? The levels are the classes of the Klimaateffectatlas's national subsidence map. Rising ground is uncommon and not good or bad in itself.
