What one wet season does
Drainage is invisible until the day it is not.
A flooded yard is the warning. What follows is a soaked crawl space, a cracked slab, a slipping slope and a repair bill several times the cost of doing it right now.
Water runs toward the house
Bad slope sends runoff straight into the foundation, crawl space and garage.
Driveways and walkways flood
Water with nowhere to go pools where you park and walk, then freezes and cracks.
Real properties
Drag the slider. Same yard, one rainy season apart.
Same house, same angle. The only difference is the drainage underneath.
