Hi Guys, Not exactly a wall question, but you guys are the experts on soil loads and drainage so I need your advice. I built the kids a 24x30 basketball court with of 5.5in concrete last fall, but did not plan appropriately for the rain water collection/shedding from the court. Instead of a slight dome in the concrete to shed water to all sides, it has a slight slope that sheds most of the water to the 2ftx2ftx30in deep concrete pillar that the basketball pole is mounted into. My concern is when we get a lot of rain, say 1-2 inches, the court could be draining 1,000 gallons in the immediate area of the pillar (720sqft x .17 rain=122cuft water x 7.5 gal per cuft). Do I need to worry that the soil down at the 30in mark will soften/weaken and allow the concrete pillar to sink? Thanks.
