split slab concrete parking deck
split slab concrete parking deck
(OP)
I have a split slab parking deck project in northern climate. It is a steel framed floor with a reinforced concrete slab. A waterproof membrane was adhered to the slab then protected by a protection board and a 3" concrete surface topping. The topping has caulked saw cut joints at 7' on center each way. The entire system slopes at 1/4" per foot to multi level drains. The construction is 7 years old. The concrete topping is cracking all over and spalling. The topping has observed cracking days after initial placement. The argument is that a drainage board was not specified or provided. We have multiple parking deck projects in northern climates that are much older without showing concrete topping damage. Does anyone have parking projects that utilized this type of system successfully (split slab with membrane, without drainage board)? Is there any national standards or research that I can reference?
Thanks
Thanks

May have been further ahead using a membrane and traffic surface...

Concrete was a normal 3000psi air entrained mix with standard slump and normal weight aggregate.
