i have a gravel driveway that slopes to my garge where the garge and driveway met their is a valley where the water is collecting i have atranch there to devert the water . but that won't last long because we drive over it to get into the garge, what kind of pipe should i use and do i need pea gravle for it or can i use that sleve for the coragated pipe? and should i put a drain great on top to help with the drainge any sugestions.
being that its gravel, I'd try to fill in the valley with more stone, to hold water I figure its packed down pretty good. also, take a look to each side of the garage to see if maybe you can landscape some to move the water away. the flex pipe with the wrap is cheap enough, can't hurt to try that, put down, cover with some stone.
