Hello everyone,
our shell for the double garage (8 x 6m) is currently being built. Soon, the formwork for the concrete ceiling (flat roof) will begin.
On the roof, a bitumen coating and gravel will probably be applied later. I have often heard that the coating is not watertight. Would it help here to use WU concrete (despite the 18-20 cm thickness)? Would that provide additional security, e.g., with standing water?
The extra cost for WU concrete would be only about 200 euros. (It could be that more rebar is needed because of WU).
Best regards
