In the article (The Concrete advantage) written by Greenrooftops, the organisation put forth to us readers that with the high initial investment of the greenroofs, various stakeholders will benefit from the enhancement of the greenroofs with the installation of waterproof concrete as it simplifies the design, building and maintenance processes.
The unique specialities of the waterproofing concrete yield positive outcomes. Waterproof concrete have permanent built-in waterproofing which cannot be tampered or worn out as compared to green-roof membranes during or after the construction phase. Minor defects such as cracks can be identified and reconditioned easily. Defects can be rectified by adopting the polyurethane grout injection repair to fill up the gaps from the bottom deck and it does not damage the plant life. Application of membrane can be eliminated thus shortening the drafting process. The cost per square foot for installation not only decreases but it also lowers the overall construction cost.
The idea of adopting waterproof concrete helps elevates the prospects of different group of people. For the designers, the detailing process is shortened and hence constructions can commence earlier. Construction is also simpler, efficient and inexpensive hence increasing the value of the property for the owner.
All in all, waterproof concrete is not only durable, but cost effective, less risky, environmentally friendly, having a high investment value in the long run and having a shortened duration for construction.
I believe that waterproof concrete green-rooftops is a stepping stone to help society achieve their main goal through its advantages; in terms of efficiency construction and cost saving, in aiding to help save the earth.
With waterproof concrete, the installation of a membrane can be negated. There are several benefits of using concrete over using a membrane.
To begin with, contractors have an easier time constructing the greenroof as they don’t have to worry about damaging the membrane in the construction progress. This in turn benefits the consumer for the construction could be done with time to spare as contractors need not wait for the concrete to achieve the desired conditions before it is ready for usage. Should there be any leakages, we may identify the source of the damage quickly and rectify it by simply injecting a resin from below the structure, therefore eliminating the concern of disrupting the green roof ecosystem.
Next, with the elimination of the membrane, waterproof concrete makes it more affordable for owners as they do not have to replace it thus lowering the ‘life-cycle cost’ for the structure don’t have to any components to wear off. Thus, installing waterproof concrete have a higher sustainability as compared to a membrane. It also helps owners to save costs by reducing the design time and cost on such projects for ‘once a structural concrete roof is designed’, basic base construction action can be ensued.
Ultimately, these factors are all not only cost saving but also construction efficient as well. These benefits are the main advantage for consumers and it is beneficial to them in the long run.
