How thick does a concrete path need to be?
Pavements for foot traffic only (e.g. paths and patios) should have a minimum thickness of 75 mm. Pavements for vehicles less than 3 tonne gross mass should have a minimum thickness of 100 mm.
Do you need wire mesh in concrete sidewalk?
It’s a heavy, heavy wire. But if you have reinforcing steel bars that go through it or the wire mesh, that makes it a lot stronger. Now in a sidewalk, typically they don’t put metal mesh in; they don’t put the mesh in there. But if it was like a driveway or a patio, they would.
How do you pour a sidewalk with quikrete?
Patio and sidewalk forms should slope evenly away from structures. Evenly spread 3 to 4 inches of QUIKRETE All Purpose Gravel and then level the gravel. Compact the gravel base using a tamper. TIP: a solid sub-base will help prevent erosion and slab settling.
Is gravel necessary 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.
Should I put plastic under concrete?
Recently, though, research has shown that the old traditional layer of 6-mil Visqueen (polyethylene plastic) under the slab is seldom effective for two main reasons: Although it may seem water-tight, this grade of material allows a lot of water vapor to pass through.
Can I pour a 2 inch concrete slab?
If done properly, new concrete can often be poured right over an existing slab. For this to be feasible, the contractor needs to pour at least 2 inches thick, use smaller aggregate, and incorporate reinforcement such as welded wire mesh or fiber mixed into the concrete.

What kind of cement should I use for a walkway?

In summary, rebar vs wire mesh can have costly differences. Rebar remains stronger and ensures consistent contact in the soil where as wire mesh is unpredictable and often results in a week concrete foundation.
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.
Do you need rebar for 4 inch slab?
No, you do not need rebar for a 4–inch slab of concrete on grade. A 4–inch-thick slab cast on the ground and in permanent contact with it will float and rebar is not required. Rebar is recommended on concrete measuring 5 – 6 inches thick.
