Hot melt is a membrane that is applied as a hot liquid directly to a prepared structural deck to create a completely seamless, monolithic layer. This is the ideal solution for the waterproofing underneath sedum roofs. Although Robseal fully endorse installing single ply PVC membrane under sedum roofs and brown roofs, generally due to poor workmanship and damage in the membrane from following trades we are finding that more clients are preferring to opt for a seamless and robust waterproofing layer. Hot melt is the answer.
This system requires good quality concrete/screed substrate and should be of a decent size, to warrant the logistics of placing a boiler on the roof.
A Hot Works Permit is required for this system which we can provide.
