Can I use mesh instead of rebar?
Concrete is strong in compression but it has relatively low tensile strength. A steel mesh has greater tensile strength and is a reinforcing material for concrete structures. Plain rebar surfaces are not used for reinforcing concrete. It is first deformed accordingly to create a strong bond with concrete.

Can I use chicken wire to reinforce concrete?
Concrete reinforced with chicken wire or hardware cloth yields ferrocement, a versatile construction material. It can also be used to make the armature for a papier-mâché sculpture, when relatively high strength is needed.
How long should concrete piers dry?

Allow the concrete to cure for one day before constructing your deck or placing heavy weight on the footing (if standard concrete mix was used, wait about 3 days to begin construction).
What’s better rebar or wire mesh?
Considering the support constraint, rebar is undoubtedly stronger than wire mesh. Several constructors consider rebar for domestic jobs. For thicker driveways and locations that involve greater traffic, rebar is always a good option to consider.
Do I 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.
