Hi. We want to use a grout for surface leveling under the baseplate of steel anchors on roof. It will be covered with secondary waterstoping membrane, thermal insulation and single-ply roof membrane. So it is inside of weatherproofing system.
1) Does this grouting fall under this credit?
2) In which category shoul I put it?
3) Is a weatherproofing system defined only by a roof membrane, or is it the whole roof slab consisted of secondary waterproof membrane/air barrier, thermal insulation and roof membrane? (then adhesives and sealants inside the roof composition are exempt, right?)
