The preferred slope is between one-quarter and one-eighth inch per running foot of floor length. As a rule of thumb, all areas around the drain should have a similar slope. To calculate this, multiply the length in feet of the farthest wall from the drain and multiply that result by 0.125.

How much slope do I need for a yard drainage?

What stone is best for drainage?
For the best drainage, look for coarse washed rock (gravel) that is screened, with a stone size of 1/2 to 3/4 inch. Smaller rock with fine particles could clog the holes of the drain pipe. Pea stone works, but the smooth stones settle together and don’t move as much water as coarse rock.
Can you push water uphill?
To push water uphill it will require pressure and if water goes downhill then you will gain pressure. An easy calculation to know is that for every 10 feet of rise you lose -4.33 psi. For every 10 feet of fall in elevation, you will gain +4.33 psi.
How do you fix a downward sloping driveway?
When dealing with a sloped driveway that collects water in low areas, the best answer is to install a trench drain that cuts directly across the driveway. This is a great solution for driveways that slope downward from street level or have a low spot.
