Reinforcing Mesh
Steel welded mesh sheets using bars of various diameters, patterns and steel grades used mainly for reinforcing concrete slabs.
Trench Mesh
Narrow welded mesh sheets using heavy bars for the long bars and lighter bars for the cross bars. Used in strip footings and beam sections in raft slabs.

reinforcing mesh on a house slab

Welded mesh or fabric as it is sometimes called is almost universally used for the reinforcement in small and in many large slab pours. It can be used in wall and it can be bent to shape on large folding machines.

The bars that form the mesh range from plain round bars to high strength deformed bars.

The advantages of using mesh rather than tied bars are convenience, speed of installation and the accuracy of the finished work.

The mesh in the photo above is manufactured in 2.4m x 6m sheets which is the normal method, though in some cases mesh can be supplied in rolls. There are for every type of mesh specific guidelines provided by the manufacturer for joining the sheets so that the strength of the reinforcing is continuous through the concrete.

  • The joints are simply overlapped by the specified amount and tied with tie wire.
  • Mesh sheets with square patterns with bars all the same size can be laid on the job in any direction.
  • Rectangular mesh has different bar spacing and many times it also uses different bar sizes and is designed to go in a particular direction. the direction of the mesh placement will be noted on the plans.
  • As with all reinforcement it should be kept clean and free from contaminants.
  • Fabric is normally cut on site with bolt cutters or angle grinders with metal friction disks.
