Fiber Mesh or Wire Mesh/Rebar?

Fibermesh is designed to resist plastic shrinkage cracks in the concrete very early in it's strength development but doesn't do much after that.

WWF and rebar (if properly positioned) are intended to hold cracks, including the ones at the bottom of control joints, from opening up. Contrary to popular opinion, neither bars nor mesh do much to prevent cracks.

I prefer rebar over mesh simply because it doesn't sag between supports and end up laying on the ground.

If you want to prevent cracks, you need to avoid re-entrant corners, increase aggregate size , minimize water content, cure the concrete properly, etc. Most people just opt to hide the cracks in the bottom of control joints.

As has been said, the most important consideration is a well compacted, granular base. The ground under the slab is going to support the weight placed on the slab. A 4, 5 or 6" slab just isn't going to span very far no matter how much bar you put in it.

So, to answer your question. If you have an excellent base and just want to prevent cracks long enough to cut some control joints, fiber is fine.

If there is any question that the base or loads placed on the slab might cause cracks or control joints to open up excessively, I'd skip over the WWF and go right to rebar. #4 bars at 24" centers is a good starting point. Hope that helps.

Fiberglass mesh is a neatly woven, crisscross pattern of fiberglass thread that is used to create new products such as tape and filters. When it is used as a filter, it is not uncommon for the manufacturer to spray a PVC coating to make it stronger and last longer. The most common place to find fiberglass mesh is in tape products.

Drywall finishers use the mesh frequently. In fact, it is common to replace the paper tape used to float the joint between two pieces of drywall. The mesh that drywall finishers use comes on a roll just like paper drywall tape. The added benefit for the drywall finisher is to roll out the mesh over a great distance before having to apply the first coat of joint compound. Not only does it help them in this manner, but it also causes a stronger bond between the joint compound, the tape and the wall.

Drywall finishers also use this tape to patch holes. The most common hole in the drywall generally occurs where a doorknob has hit a wall too many times. If it is only slightly damaged, a couple of short pieces of the tape will be formed into a square and placed over the hole. A joint compound will then be applied directly to it. If the hole is too large to patch with fiberglass mesh alone, a piece of metal flashing can be added behind the tape before applying joint compound. Construction work is not the only use for fiberglass mesh.

As a filtering system, alkali resistant fiberglass mesh works really well. As the water flows through it, the mesh catches even the smallest impurities. In addition to this use, it can also be used as a mosquito net.

Firefighters and others who work with dangerous chemicals may use fiberglass mesh in protective clothing. Firemen wear jackets made of tightly woven mesh when they are battling a fire. During firefighting, it keeps their clothing from catching fire. Among other things, fiberglass mesh can be used for mold making as well as for protection againstcorrosive chemicals.
