Our instructions removed the blotter layer in 1999. I look forward to getting deposed because it is not the Architect's fault. It is the structural engineer to whom they subbed out that work. I can't wait to throw him under the bus.

Even CalGreen (the new building code) still allows for it if the slab is "designed by a structural engineer". Well ... I can't wait to see one of these engineers get sued. They are the ones who are the cause in fact for 80% of the floor failures we have had to deal with. Not the flooring sub, not the gc, not the architect, not the curing compound, not the adhesive, not the material suppler, the engineer should be blamed.

It will be interesting to see what gets decided. But, it will probably settle out of court.

I disagree. Each sub inherits from the sub before him. If I put a floor on a wet slab, shame on me. If I put a rubber floor on a concrete slab with a blotter layer in strict disregard to the applicable ASTM's then shame on me!!! If the concrete sub sprays a sealer all over the slab and the installer goes over it and it fails, it's the installers fault!
