Question 1

Is steel mesh reinforcement better than individual rebars?

Accepted Answer

Steel mesh reinforcement is quicker to install and ensures consistent bar spacing across slabs, saving labour time. However, individual rebars may still be needed for beams, columns, retaining walls, or irregular shapes where welded mesh sheets cannot be positioned effectively. Both methods are often used together.

Question 2

How much overlap is needed for concrete mesh?

Accepted Answer

Reinforcement mesh should overlap by at least one full square to maintain structural continuity and load transfer between sheets. Always follow the project’s engineering drawings, as some designs may specify longer lap lengths for heavier loads or critical structural areas where additional strength is needed.

Question 3

What’s the difference between fabric reinforcement and rebar sheets?

Accepted Answer

Fabric reinforcement is a prefabricated welded steel mesh manufactured to standard sizes for quick placement. Rebar sheets are assembled manually on site from loose bars tied together, allowing customised layouts for complex structures. Both serve similar purposes but suit different construction methods and design requirements.

Question 4

How many spacers do I need for reinforced steel mesh?

Accepted Answer

The number of spacers depends on the sheet size, mesh weight, and slab thickness. As a general guide, place spacers every 800mm to 1,000mm in both directions. For a standard 4.8m × 2.4m sheet, this usually means around 12 to 16 spacers. Heavier mesh types or thicker slabs may need more supports to prevent sagging. Always follow the engineer’s drawings or site specifications for exact spacing and quantity.
