In the previous post I have been illustrating how I plan to build the Roof System for the Net Zero Hemp Home. This post shows how I plan to both Insulate the Catalan Vault Style Roof System and make it water proof.
I found some additional details in English at this site http://www.mexico-insights.com/judysblog/post/Brick-Lakesidee28099s-Cornerstone-Part-7-The-Roof.aspx. I am now following the author on Twitter and FB! I’ll have more info on waterproofing the roof ASAP. I will also be contacting the Hempcrete Pros for their suggestions in incorporating their product into this system.
See the Youtube Video of how these Spanish Masons Waterproof the Catalan Style Roofs:
