Here we had a concrete roof deck that was leaking so we applied a 2 x layer flame bonded Membrane, then polished stones were placed over the membrane for protection.

Before: Area to be covered with membrane

During: Here we have all the different stages & layers:

1. Bare Concrete
2. Black Primer Liquid
3. 1 x layer diffuser (with holes)
4. 1 x layer plain 3mm
5. Stones laid over as to protect from sun
