Thereof, Do you have to put gravel down before pouring 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.

Then, prepare a bonding slurry to ensure the new concrete adheres to the previous layer. Dampen the existing concrete, apply the bonding slurry, then add your new concrete.

How do you blend old and new concrete?
Do you need wire mesh in concrete sidewalk?
Reinforcing concrete sidewalks with wire mesh helps to bridge over small imperfections in the subgrade. This lessens the likelihood that sinkholes will develop. Concrete sidewalks can be replaced in sections that mesh together nicely, although the color does not always match (few materials do).
Can you pour your own concrete slab?
For most do-it-yourselfers, the best material for building a concrete slab is ready-mix crack-resistant concrete mix. The wet mix is poured into a prepared wood form, then left to cure. After the concrete has hardened, the sides of the form are knocked off and the slab is ready to use.
Can you pour concrete slab without rebar?
Not all surfaces need concrete rebar reinforcement, but adding it makes concrete stronger and more resistant to large cracks. … Without rebar reinforcement, concrete is highly prone to cracks due to tension forces. Rebar helps prevent cracks from growing wider largely by preventing cracked slabs from moving apart.
How many inches of gravel do you need for a concrete slab?
Construct the form with 2×4 or 2×6 lumber and secure in place by wood stakes and deck screws. Excavate the slab area to a depth of about 7 inches, allowing 3 inches for a gravel base and 4 inches for concrete.
What kind of gravel do you put under concrete?
Backfill beneath concrete flat-work along foundation walls should be accomplished with a granular material that is uniform in size. Some fill materials, such as round stones like pea gravel, tend to be self compacting. “I recommend open-graded granular material be used,” says Tull.
