 Common strategies used to direct water away from building foundations

#Rainwater and #snow-melt that do not drain away from a #foundation and into a #drainage system will seep into the soil next to the foundation. If the water cannot percolate downward quickly through the soil to a level below the footings, the soil can become saturated and can even create #hydrostatic pressure against the foundation and beneath the floor. This can cause leakage into the #basement or crawl space.
