Choosing the Right Concrete Reinforcement

At County Building Supplies, our branch teams help builders, contractors and DIY customers choose concrete reinforcement for a range of construction projects. Whether you're pouring a concrete floor, constructing foundations or working on another reinforced concrete project, using the correct reinforcement and positioning it properly is important for the strength and durability of the finished structure.

Reinforcement Mesh or Rebar?

One of the most common questions when choosing concrete reinforcement is whether reinforcement mesh or individual rebar is required. Both are used to strengthen concrete, but they're suited to different applications and should always be selected in accordance with the project's structural specification.

Reinforcement mesh consists of steel bars welded together to form a grid. It's commonly specified across larger areas of concrete, including floors and slabs, where reinforcement needs to be distributed throughout the concrete.
Rebar consists of individual steel reinforcing bars that can be positioned within concrete to provide reinforcement in specific areas. It's commonly used in foundations and other structural concrete applications.

County Building Supplies stocks concrete reinforcement including A142 reinforcement mesh and M12 12mm reinforcing bar. The reinforcement required will depend on the structural design of your project, so always follow the relevant drawings and specifications.

What is A142 Reinforcement Mesh?

A142 is a commonly used steel reinforcement mesh for concrete applications. The welded grid helps distribute reinforcement across the concrete and can be specified for applications such as concrete floors and slabs.

The correct mesh grade, quantity, position and concrete cover will depend on the structural requirements of the project. If your plans specify a particular reinforcement grade, always use the reinforcement stated by the designer or structural engineer.

Positioning Reinforcement Correctly

Choosing the right reinforcement is only part of the job. Reinforcement must also be positioned correctly within the concrete to perform as intended. Spacers and supports can be used to maintain the specified position and concrete cover during the pour rather than allowing reinforcement mesh to simply sit directly on the ground or base.

Requirements vary depending on the structure, exposure conditions and design, so reinforcement should always be installed according to the project's structural drawings and relevant specifications.

Cutting Reinforcement Mesh & Rebar

Reinforcement mesh and rebar can be cut on site using suitable equipment where required. Before cutting reinforcement, check the structural drawings carefully to make sure the required dimensions, overlaps and reinforcement layout are maintained.

Appropriate personal protective equipment should always be worn when handling and cutting steel reinforcement because cut edges can be sharp and the material can be heavy and difficult to manoeuvre.

Need Advice?

If you're looking for concrete reinforcement for your project, visit your local County Building Supplies branch or contact our team. We can help with product availability, quantities and delivery, while reinforcement type, positioning and structural requirements should always follow your project drawings or structural engineer's specification.

Frequently Asked Questions – Concrete Reinforcement

What is concrete reinforcement used for?

Steel reinforcement is incorporated into concrete to help it resist tensile forces and control cracking. It's commonly specified for concrete floors, slabs, foundations and other structural concrete applications where additional reinforcement is required.

What's the difference between reinforcement mesh and rebar?

Reinforcement mesh consists of steel bars welded together into a grid, making it suitable for distributing reinforcement across larger areas such as concrete floors and slabs. Rebar consists of individual reinforcing bars that can be positioned where reinforcement is required within foundations and other structural concrete elements.

What is A142 reinforcement mesh used for?

A142 is a commonly specified reinforcement mesh used in concrete construction, including certain floor and slab applications. Whether A142 is suitable for your project depends on the structural design, loading and concrete specification, so always follow the reinforcement requirements shown on your project drawings.

What is 12mm rebar used for?

12mm reinforcing bar can be used in a range of reinforced concrete applications, including foundations and other structural concrete work. The required bar diameter, spacing and arrangement depend on the structural design, so you should use the reinforcement specified for your project.

Do I need spacers under reinforcement mesh?

Reinforcement mesh generally needs to be supported at the correct position within the concrete rather than simply laid directly onto the ground or base. Suitable spacers or supports can help maintain the specified concrete cover during pouring. Follow your structural drawings for the required reinforcement position and cover.

Can I cut reinforcement mesh and rebar to size?

Yes. Reinforcement mesh and rebar can be cut on site using appropriate equipment. However, you should check your structural plans before cutting to ensure the required dimensions, overlaps and reinforcement arrangement are maintained. Always use appropriate PPE when cutting and handling steel.

How much should reinforcement mesh overlap?

The required overlap depends on the reinforcement specification and structural design. There isn't one overlap measurement that's suitable for every project, so the lap dimensions shown on your structural drawings or specified by your structural engineer should always be followed.

Can reinforcement mesh stop concrete from cracking?

Reinforcement can help control cracking and improve the structural performance of concrete, but it doesn't guarantee that concrete will never crack. Concrete mix design, ground preparation, joints, curing, reinforcement positioning and environmental conditions can all affect cracking.

Do you sell full sheets of reinforcement mesh?

Yes. County Building Supplies stocks full-size reinforcement mesh sheets, including A142 3.6m x 2m reinforcement mesh. Product availability can vary, so check online or contact your local branch before ordering larger quantities.

Do you deliver reinforcement mesh and rebar?

Yes. We offer local delivery for reinforcement mesh, rebar and other building materials. Because reinforcement sheets and bars are large products, delivery availability may depend on your location, order quantity and site access. Contact your nearest County Building Supplies branch for more information.
