Balconies
Balconies are often overlooked when waterproofing is considered, but when rooms are below it is a critical area requiring some of the best waterproofing imaginable.
Balconies are usually a high traffic area exposed to all the elements like sun and rain, and has opposing thermal expansion rates with the membrane adhered to both the substrate and the covering like tiles on top.
A butyl rubber membrane installed onto a balcony before the final surface is applied can provide you with peace of mind for a lifetime.
