Please Note:

What depth should mesh be in concrete?

Use wire mesh for driveways that are 4 to 5 inches thick, and rebar for those that are 5 inches or more. Place rebar in a grid pattern with a spacing between bars of approximately 12 inches. In either case, blocks should be used under the reinforcement to keep centered within the concrete.

Do you need wire mesh for 4 inch slab?

No, they do not. Larger projects or slabs may need steel reinforcement to provide support or extra strength. Wired mesh can also help resist cracking. However, not every piece of concrete necessarily requires that extra boost.

What is A142 mesh used for?

A142 2.4m x 4.8m (Standard Size) Reinforcement Mesh Fabric
A142 mesh is often used in light duty domestic concreting in floor slabs and foundations with a thickness or depth of 100mm. The most common uses for A142 mesh is pathways, driveways and garage bases (depending on the vehicle size and traffic levels).

What does SL82 mean?

What does SL82 mesh stand for?

Square mesh
This is designated SL62, SL72, SL82, SL92 or SL102. The first digit refers to the diameter of the bars. The last digit refers to the spacing of the bars. For example, SL72 has diameter 7 mm bars, which are on a grid of 200 mm apart.

Does steel mesh stop concrete cracking?

By having steel reinforcement mesh underneath the concrete, it helps stop the slabs from cracking.

How much weight can a 4-inch concrete slab hold?

A 4-inch thick concrete can support upto 40 pounds of weight. Weight should not exceed 40 lbs/sq ft on an undetermined 4-inch slab. 80 lb/sq ft in isolated areas is fine, but unless you know what the soil bearing and reinforcing is for that slab, you might be looking at cracking.

Is wire mesh better than rebar?

Support: 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.
