what if I want a clean concrete finish on a flat roof to use for recreation? Can I pour concrete on top of it or how is it done?
If you use concrete, you dont need vacum system. Concrete is ballast.
Just use type G membram between. Without fastenings, just weld it together then pour concrate on top but u have use some delatating membram beetwin. Chemical reactions will eat membram. For this case asphalt is better
