GatorBar Vs. Welded Wire mesh

Erik was out of town the other week and happened to stumble across a pile of crumbled concrete in New Hampshire. He stopped by to check it out, and of course, take advantage of a perfect real world example. Welded wire mesh, though inexpensive, is not your best option for reinforcing a slab for crack control. 

When contractors use welded wire mesh, they typically lay the mesh on the ground, pour the concrete on top of it, and then try to pull it up to the center as they go. Unfortunately, this doesn't work very well and the mesh often ends up at the bottom of the slab where it adds no value. Rebar chairs are rarely used for a couple reasons: Chairs are easily snapped if someone steps too close to them. Also, wire wesh is easily bent and becomes mangled when stepped on during the pour if it is chaired up.

GatorBar is different. It is high strength, lightweight and flexible. You can tie it into grids and then chair it up without having to worry about breaking chairs or bending the mesh. GatorBar springs back after being stepped on, staying centered in the slab.

I wanted to drop a line and comment on your GatorBar product. This is the second project we’ve used it on and the first one that we used a power rake with. We placed the bar 18” OCBW and chaired it to 2 1/2” for a 5” slab. The GatorBar worked well, in particular we noticed how it rebounded back to the center of the slab after we drove over it, with steel rebar the rebar would often end up bent and left at the bottom of the slab, where it does nothing for crack control. Also, the labor savings on rebar placement was significant and I know the crew appreciated not having to wrestle with the heavy steel. We look forward to using it again on future projects.
