Negative grade at the front of my home appears to be the leading cause of the infiltration of a stream of water into my upper crawlspace. Previous owners had a trench dug at the upper block wall creating a mini retention pond. Crawlspace is dry for the most part except for this area. No indications of mold on the floor joists. Pretty sure water is infiltrating through the flower bed. Leak is directly behind this location.
SOLUTION#1- excavate the dirt in flower bed and concrete this area. Use large pots for plants.
SOLUTION#2- install a drain in the upper crawlspace and pipe water out at lower wall.
SOLUTION#3-excavate dirt and install poly barrier.
Any advice would be much appreciated.
