This presents a challenge during concrete placement as the workers have to walk on or maneuver around the elevated wire mesh. More commonly there are continuous steel bolsters which are laid parallel to each other as often as is required to support the mesh and any traffic on top. There are many kinds of wire mesh bolsters available There are plastic standalone supports which support the mesh at intersecting wire. Sometimes the engineer will require the mesh be placed on bolsters or chairs to assure the mesh will rest in the correct portion of the slab section. Even small slabs which may not require reinforcement may benefit by the use of welded wire reinforcing mesh to add strength and control cracking. To compensate for concrete weakness welded wire reinforcing mesh should be used in concrete applications. Wire mesh can come epoxy coated (to resist o resist corrosion and rust) or ‘black’ steel which is uncoated. Used to increase the tensile strength of concrete slab.

Many engineers simply feel placement in the center of the slab is a logical compromise, offering some flexural strength increases in both bending applications mentioned above. This is why it is common for some engineers to specify mesh in the upper and lower 1/3 of the slab both. When placed in the top 1/3 of the slab, it will have increased flexural strength in between two point loads which bend either side of the slab downward. When wire mesh is installed in the lower 1/3 of the slab, it will have increased flexural (and in turn tensile) strength when one point load bends the slab downward. The accuracy of this theory depends on where the wire mesh is placed and how well the subgrade is designed and compacted: Wire mesh in a slab can offer tensile/flexural strength to the concrete, spreading loads over more area.Ī common thought process is that steel wire mesh keeps the slab from cracking. Īlso, another situation where wire mesh can offer benefits is when a poor or weak subgrade exists and may be expected to move or settle. to increase flexural strength of the slab.

On the other hand, ACI 315.99 enshrines both 8' minimum (deformed wire mesh) and cross wire spacing plus 2' (6' minimum) for plain. Therefore, your wire mesh (probably 6 wire) is 0.16 diameter.
