Water leakage is one of the biggest problems in old buildings. It always causes a lot of nuisances to residents. However, new sustainable technologies have allowed roof to become “greener” with different strategies, such as plantations, photovoltaic panels and solar reflective paints. With the combination of waterproofing technology, green roof could remain its life time to last more than 30 years.

According to the report of World Green Building Council in 2019, building and construction are responsible for 39% of all carbon emissions in the world, with 11% from materials and construction processes throughout the whole building lifecycle. Construction industry around the world is pushing for decarbonization strategies. By choosing a suitable waterproofing system, decarbonization could be achieve from material manufacturing, application, expected life expectancy and maintenance of the system.  

In this webinar, the speaker will introduce the design considerations, and the different types and methods of waterproofing systems. Depending on the type of material, each of these systems has their own methods of application, such as Cold-Applied and Hot-Applied waterproofing systems, Re-roofing and Overlay methods . The speaker will introduce the opportunity to create sustainable roof with different waterproofing technology from the angle of cost effectiveness.
