How much of a slope can you pour concrete?
The standard slope for proper concrete drainage is a one-quarter inch drop for every foot of length. So, to calculate the difference in height between one end of a patio or walkway and another, simply multiply the length by one-quarter.
How do you pour a concrete pad on unlevel ground?
Smooth out the ground and then check the level in all directions. Add and remove dirt as needed until the entire area is level in every place you measure. Tamp down the surface until the soil is tightly packed and be sure to check that the area is level from corner to corner.

2. Set forms so that the concrete slab surface slopes a minimum of two percent, or 1/4 inch per foot, to provide adequate drainage.
What is the minimum slope for drainage?
For efficient drainage, paved surfaces should have a minimum 1-percent slope. Turf or landscaped areas should have a minimum slope of 2 percent.
Can you pour concrete directly on dirt?
Long story short, yes you can pour concrete over dirt.
Do you need gravel under concrete?
Whether you pour concrete for a walkway or patio, a strong gravel base is required to prevent the concrete from cracking and shifting. Gravel is especially important in clay soil because it doesn’t drain well, which results in water pooling under the concrete slab and slowly eroding the soil as it finally drains.
Is it cheaper to pour your own concrete?
Whether you’re pouring concrete countertops or a patio out back, it may be cheaper to pour concrete yourself rather than hiring someone. Whether you’ll save much in doing so depends largely on the amount of concrete needed and the amount of time you have to invest in your concrete project.
