How does groundwater flow affect a building’s foundation?
Rising water tables can reduce soil strength which can lead to slope collapse.In areas with severely unstable slopes landslides can cause significant damage to buildings. Lower groundwater levels can cause soil consolidation which can cause subsidence.
How does the groundwater level affect the foundation?
In areas where the groundwater table rises locally near surface water a condition called “hydrostatic pressure” pushes the underside of the foundation. ‘ This can cause water to seep into the bottom of the foundation – and even into solid concrete over time.
