wire mesh codes

radmix

I just looked at a project with approximately 5000 sq ft of slab radiant.  I was informed that there will not be wire mesh in the slab due to the code that states the wire mesh had to be grounded because of interference with communication wiring in house. They will be using fiber concrete instead. The problem is that all of the tubing has to be stapled down to the insulation increasing the labor on the project. Has anyone else ran into this?
