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 article, concrete green roofs which incorporates ““Permanent
built in water-proofing”” will not be damaged. It will have higher sustainability and
lower construction costs. The removal of membranes on developments will shorten
the process of design, construction and maintenance. The article 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, water-proof concrete green roof will definitely make a more feasible
choice as compared to typical green roof for owners, designers and contractors.
The first reason why concrete
green roof makes a better choice is because of the benefits that it can provide
as mentioned in the article. Research studies has shown that besides being
sustainable, the concrete green roof is very durable and is cost effective. In
comparison with the typical green roof and the waterproof concrete green roof,
the typical green roofs are more inclined to wear and tear despite applying
root barrier coating. Plant roots can easily go through the waterproof membrane
and can cause leaks in the roofs which can lead to structural damage to the
buildings. To get rid of leaks, frequent checks must be done and this can be
costly. Contractors must also be cautious during the application of the
membrane and designers have to come up with a detailed design of the membrane.
All membranes become brittle over time and this are caused by exposure to heat,
cold and UV rays from sunlight. Therefore, typical green roofs require
additional maintenance and precise manufacturing to protect and develop the
membranes. This increases the cost of the roofs. With the implementation of
waterproof concrete green roof, it reduces the need of additional maintenance
and will ease the jobs for the contractors and designers as they do not have to
apply or specifically design any membranes. Therefore, this will speed up the
construction time and reduce the cost of developing and maintaining the roof.
In the article “Concrete that
fears water no more” from Hycrete (2007), states that the cost of waterproofing
membrane is 40% more expensive than waterproof concrete. This statement shows
that waterproof concrete is a better choice as it is less costly as compared to
waterproofing membrane. The article also states that waterproofing membrane is
applied to every square inch of the concrete in order to make the structure waterproof.
This statement shows that it will be a tedious task to apply waterproofing
membrane and it will increase costs due to labor requirements and requires
additional waterproofing maintenance to ensure that the membrane does not wear
out.
In conclusion, waterproof
concrete green roof makes a better choice because of the advantages that is
stated in the above mentioned paragraph. Apart from the stated advantages, I
feel that efficiency is the key to success in the construction industry and
choosing the right waterproofing method can make or break a project’s timeline.

Dear Cherlyn,
ReplyDelete1)Summary is understandable and clear whereby I know what the article is mainly explaining about.
2) Clear transition to the thesis based on the summary.
3)Reader response is well explained to back up your thesis and quoted outside source to support your stand. Brought in more advantages of waterproof concrete green roof so as to make your thesis stronger. Conclusion of the reader response showed the user had some critical thinking.
Thank you for reading my comment!
Best Regards,
Clarabelle
This essay has a very good 2nd draft of the summary/reader response, Cheryl. It seems you have captured the main points of the article in your summary. You also express a clear position on what you have read as a thesis. In the response, you elaborate very clearly on the benefits of the waterproof concrete green roof, which, as one minor criticism, is a phrase that you need to use more consistently in the essay. What I also like is the cohesion of your ideas. Thanks for the great effort.
