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.
What depth should a concrete path be?
Concrete footpaths A simple concrete pathway up to about 1m wide used solely for foot traffic: The thickness of the concrete – 75mm (3 inches). The thickness of the sub-base – none normally required.
What kind of concrete do you use for a walkway?
QUIKRETE ® Concrete Mix is a good general-purpose mix for sidewalk and slab work. T-square, measuring tape, mason’s line, pickax, rake tample, hammer or half-hatchet, darby or bull float, hand float, finishing trowel, bricklayer’s trowel, edger.
Do you need gravel under concrete sidewalk?
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.
Can you pour concrete directly on dirt?
Long story short, yes you can pour concrete over dirt.
Is rebar better than wire mesh?
Rebar remains stronger and ensures consistent contact in the soil where as wire mesh is unpredictable and often results in a week concrete foundation.
What is the minimum concrete thickness?
The minimum recommended thickness is 1 to 2 in. ( 25 to 50 mm ) for a fully bonded concrete overlay placed on a base slab that is practically free of cracks and in which the concrete is sound, clean, and of good quality.
Can you lay concrete on concrete?
In most cases, the answer is YES! You can do that, but the existing slab must fulfill certain conditions to support a new concrete layer.
What is the best base for concrete slab?
Most concrete contractors want a mix of coarse and fine aggregate to create a compactable base that is going to be safe for settlement and drainage. Crusher run (a mix of crushed stone and stone dust) is one of the best base materials for concrete flatwork.
Do I need rebar for a concrete walkway?
Do Sidewalks Need Rebar? Most sidewalks don’t need to be reinforced with rebar. Rebar is a steel bar used to reinforce the strength of concrete used to withstand heavy weight. A reinforced sidewalk can complicate repairs.
Is quikrete as strong as regular concrete?
Quikrete fast setting concrete is just as strong as regular concrete. Concrete gets its strength from a chemical reaction that occurs over time during curing. After it’s had time to cure, which usually take 28 days to complete, Quikrete can reach strengths up to 5000 psi.
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.
What happens if you don’t put gravel under concrete?
Because concrete is a very porous material, it will absorb any moisture that it contacts. This can cause pooling. Without crushed stone, pooling water will settle under it and erode your slab.
Can I use pea gravel under concrete?
If you use pea gravel beneath a patio, take a few simple steps to ensure the stability of the base before setting your surface stones, pavers or bricks. Click to see full answer. It should be ok to pour concrete over your gravel walk although you might want to give the concrete a little more depth along the sides.
Is sand a good base for concrete?
Pour concrete over a solid, well-drained base of sand or gravel over clay and other poorly draining soils to provide even support.
