I love gardens but..................
Check for downspouts diverters not discharging water far enough away from the house. Check floor lawn irrigation systems spraying water against the house foundation, and check for gardens or planters that are up against the house. These may be causing wet soil pressure problems for the structure.
The illustration shows a potential problem related to a garden located up against an exterior wall of a building. The water-saturated soil of the garden is the source of the water intrusion or infiltration problem visible from inside the house at the floor framing components above the foundation wall. There may be wood rot observed in this location. On the outside, the water problem could be damaging buried structural components such as the masonry brick that are in contact with wet soil and have cracked into pieces. www.nachi.org
