The article “The Concrete Advantage” taken from the Green Rooftop website provides readers with a deeper understanding and states the benefits of having a water-proofing concrete green roof. According to the website, concrete green roofs incorporates ““Permanent built in water-proofing”” will not be damaged, have higher sustainability and lower construction costs. The removal of membranes on developments will shorten the process of design, construction and maintenance. The website states that with lesser exposure risk for owners and designers, water-proofing green roofs are more economical which boost return on investment and project value. It is also more cost effective for owners as there is no need for replacement of membranes thus lowering life-cycle cost. The website also mentions that the usage of “hydrophobic technology” removes dangerous components, making fewer contacts risk for anyone who owns a green roof. When there is crack on the concrete green roof, a simple inoculation from the bottom side will mend it without disrupting growing medium or plants. With these in mind, I agree to a certain extent that water-proof concrete green roof makes a more feasible choice as compared to typical green roof.
