How to waterproof a balcony

Bituminous membranes are the most popular system used to waterproof under the substrate of balconies. These membranes are derived from the distillation of crude oil.  

How long does a balcony with Waterproofing Last?

A balcony should last for at least 10 to 25 years. But the longevity of a waterproofing system will depend on the thickness of the membrane, workmanship, usage and weather conditions that the balcony must withstand. 

Waterproofing your balcony will help preserve the durability and status of your building, while also reducing maintenance and repair bills.

Balconies must withstand a significant amount of external elements, including extreme weather, foot traffic, organic growth and corrosive effects from pedestrian-transferred chemicals (including rock salt).
