Summary:
Waterproof concrete can be a more viable option for future
green rooftops benefiting society even further. As compared to the usage of
membranes, waterproof concrete is relatively easy to implement. It is much
sturdier and does not deteriorate with age. As concrete is used, it will hardly
be affected or damaged during construction, making it a much more simpler
option, leaving the designers lesser things to worry about.
With the application of concrete, all the designers have to
do is to wait for it to set and use it as a working platform. With that in
mind, the designers can proceed straight to construction without having to wait
for the concrete to set prior to introducing the membrane to the green roof.
Due to the waterproofing nature of the concrete used, further
waterproofing will no longer be required. This in turn play a big part in
reducing cost and time used for construction. As concrete does not wear out or
deteriorate over time, maintenance is at minimum as compared to when membranes
were used. This will lead to the increase in its sustainability and at the same
time lower its life cycle cost.
With regards to maintenance, issues such as leakage can be
easily detected since it is caused by crack or from a loose seal. With a simple
polyurethane grout injection it can be easily fixed from below without
disturbing the green roof above. As for a membrane system, when an issue
arises, it is difficult to pinpoint the location of the problem. The reparation
fee is not only costly; it might also cause damage and disruption to the entire
green rooftop system.
Thesis statement: I believe that using waterproof concrete for green rooftops
is a good investment for both the owners and the society as it offers many
benefits such as cost savings.
I feel that adopting waterproof
concrete on green rooftops is a better option for both the owners and the
society. The writer listed countless of distinct features using waterproof
concrete, which further emphasizes the benefits of using it as compared to waterproof
membranes. The benefits mentioned were applicable to many interested parties
like the owners, society and investors who wish to adopt the waterproof
concrete for the green rooftops. Benefits like cost savings, time saving and
improved qualities of the product are the determining factors to bring about
the change in the people’s mindsets of using waterproof concrete.
Firstly, the reason
why waterproof concrete is a better investment for both the owners and the
society is because of the numerous benefits that it offers as compared to using
waterproof membranes. Waterproof concrete has a permanent built in
waterproofing feature, which does not deteriorate with time and is not easily
damaged due to different weather conditions. With this in mind, investors or
owners would naturally go for products with longer lifespan to increase their
return of investment; with a lower cost price to produce a higher valued
product. I feel that having a good investment means forking out an amount lower
than the expected return rate for a highly valued product. In this case, the
writer captures the attention of investors by repeating the key factors, costs
and time, to reiterate the advantages that the waterproof concrete will bring
about to the society.
In addition, benefits
like lower construction costs and reduction of time spent to construct the
waterproof concrete were the factors, which sparked the interest in investors
and owners. With a shorter time spent on completing the project, this would
mean that the viability and feasibility of the project would increase. It is
definitely a win-win situation for both the investor and the owner, as both
parties would stand to benefit from project with an increase in sustainability
and effectiveness. With that being said, (The Growing Green Guide, 2014), the ineffectiveness of using
waterproof membranes increases as it is prone to failure due to its soft
composition and the installation requires a high degree of skill which makes it
time consuming as compare to waterproof concrete.
In conclusion,
adopting waterproof concrete is a good investment for both the owners and the
investors as it saves costs and time. With so many advantages being mentioned,
investors would be reassured to replace waterproof membranes with waterproof
concrete. Ultimately, the investors will prioritize their return of investment
and the feasibility of the project. Waterproof concrete will be able to produce
good returns at a lesser cost for the investors to make it a good investment.
