Concrete Forms

Concrete forms and slab-preparation products help concrete crews prepare for pours, including positioning reinforcing wire mesh above a membrane. When selecting mesh chairs, consider the required mesh-up height, compatible wire gauge, attachment method, base design, and how the support responds when mesh is pressed into place.

Choose Concrete Form and Reinforcement Support Products for Slab Preparation

Concrete slab preparation depends on keeping reinforcing mesh positioned before and during placement. Plastic reinforcing mesh chairs are designed to snap onto compatible wire, raise mesh above the ground, and provide a base that helps limit entry into the subsurface.

Use Cases

Prepare reinforcing mesh for slab placement

Use plastic mesh chairs to raise reinforcement wire mesh above the membrane during concrete slab preparation and pouring.

How to Choose

Match height and wire compatibility

Confirm the needed mesh-up height and choose chairs compatible with the reinforcement wire being used. The featured chair is compatible with #6, #8, and #10 wire.

Applications

Support mesh before and during a pour

Snap-on chairs attach to compatible reinforcement wire to help hold mesh in position as the slab is prepared and concrete is placed.

Additional Info

Consider support response and base design

Flexible plastic chairs can deflect when mesh is pressed and rebound toward their original position. A large base ring helps reduce the tendency to enter the subsurface.

Planning Guide

Plan the right fit before choosing

Start With Reinforcement Position

Select a chair that supports the required mesh-up height

Mesh chairs are used to lift reinforcement wire mesh off the ground for slab preparation. Review the required mesh position for the work and select a chair designed for that height.

  • The featured chair provides a 4 in. mesh-up height.
  • Raised mesh positioning supports slab preparation.
  • Confirm the chair suits the reinforcement layout before placement.
Check Wire Fit and Installation

Choose compatible chairs for the wire in use

A secure fit begins with matching the chair to the reinforcement wire. Snap-on installation allows the chair to attach quickly without tying.

  • The featured chair fits #6, #8, and #10 wire.
  • Snap-on attachment avoids tying.
  • Install chairs before and during concrete placement as needed to help position mesh.
Evaluate Contact With the Subsurface

Look for a base and material behavior suited to placement

When mesh is pressed onto a chair, flexible plastic can deflect and rebound toward its original position. Base design also matters where contact with the subsurface may affect chair position.

  • Flexible plastic support deflects under pressed mesh.
  • The chair rebounds toward its original position.
  • A large base ring helps reduce the tendency to enter the subsurface.
