@@growinggardeners Hi! I have one question, you mentioned right at the start of the video the roof was already waterproofed, how did you waterproof that? Is that a cement structure or is that stucco?
Hey @@supersports88 , yes its a concrete slab which the builder had already prepared. I think they used a bituminous waterproofing layer on top of the slab.
Excellent video! Thanks for sharing. I'm looking to create a green roof in Cape Town and was wondering if you have ever done one with Spekboom? Interested to know if the root system will allow a shallow soil system. Or if I need to just grow Sedum.
Hi Barry, yes spekboom works well on a greenroof. It can survive with a very minimal root system. If anything, you may have to keep an eye on it to make sure it doesn't get too big and put too much weight on the roof. But if it is planted in a shallow growing medium, it shouldn't get too big.
The water would drain through the soil substrate into the drainage layer, and then out through the roof's drainage pipes. There should be no issues with a continual amount of water. The issue may come in when the amount of water exceeds the existing drain pipes ability to drain away, in which case, the water would begin to overflow over the sides of the roof. But this would occur regardless of whether their was a roof garden in place or not.
Hey! Thanks for the comment...yes we are in Kwazulu Natal in South Africa. Its more of a humid subtropical climate, similar to Florida. What class are you watching the video in?
@@growinggardeners I'm doing a horticulture course with Academy Canada, and our current course content is covering green walls and roofs. Our teacher showed some of your videos in our class today, and we all got side tracked trying to figure out where you are hahaha Thanks for the video tho!
Nice! Hope you're enjoying the course... Ha ha...I guess the accent would have been weird from a Canadian perspective? Good to know that people are finding the information useful!
Thank you! I used this video for my high school engineering class :)
That's great! Glad it helped...
Thanks for uploading this.
My pleasure Adreanna! Thanks for taking the time to comment🙏🏼
Would love to see how things turn out in a few mths time
Thanks Chris...will definitely do a follow up once its established!

How does it work if there is continuous storm?

my class is trying to figure out where you are in this video. Somewhere tropical obviously
