It’s now common practice to make a rooftop garden in residential buildings.
Making a walkway in the garden is a nice idea. It increases the aesthetic look of the garden. Dwellers can use the walkway for walking as well as for jogging.
Recently I’ve made a walkway in the rooftop garden in one of my projects.
I’ve made some mistakes during making the walkway and now I’m rearranging the walkway.
In this post, I’ll share my experience – How I made the walkway and what mistakes I’ve made.
Let’s first discuss how I made the walkway.
How to Make a Walkway in The Rooftop Garden?
There are many ways to make a walkway in rooftop gardens. There are also many things to consider before making a walkway. These things are – the design of the walkway and which materials you’ll use for the walkway.
Walkway Design in The Rooftop Garden
You first need to think about the design of the walkway.
Do you want to make the walkway round or rectangular?
Consult with an architect to get the idea of the rooftop garden design.
I’ve asked my project’s architect to provide a drawing of the rooftop garden design. He gave me an excellent design with a rectangular walkway and sitting arrangements.
Materials For The Walkway
The second thing you need to consider is which materials you’ll use for making the walkway. You can use bricks, pebbles, even tiles for the walkway.
My project’s architect suggests me to use concrete slabs. So, we’ll use concrete slabs for making the walkway.
Making Concrete Slab
As per the architect’s design, we’ll use concrete slabs for making the walkway. So, I decided to make the required numbers of slab first. The size of the slab is four feet by one foot. And the thickness of the slab is three inches.
I planned to make the slabs separately and after filling soil in the garden, I’ll place those slabs in the garden.
I first counted the required numbers of slabs. I found that we need 144 numbers of slabs for the walkway.
We make five forms to make those slab. We make those slabs with these five forms and stacked on the roof.
When stacking these slabs on the roof, keep in mind that stacking all the slabs in one place can hamper the structure. So keep those in several places. And try to keep the slabs on beam. So that loads of slab distribute uniformly without hampering the structure.
We took several days for making those slabs. Simultaneously we’ve made sure the curing is being done properly of the slabs.
We’ve also made sixteen numbers of triangular-shaped RCC slab for corners and middles of the walkway.
Placing Walkway Slabs in The Garden
Once the garden is filled with soil and ready for making the walkway, we just started placing the slabs.
We decided to keep four inches gap in between walkway slabs (this is one of our mistakes, I’ll discuss this later).
The second thing we decided is that, We’ll place slabs three inches above the level of the garden soil (that is our second mistake).
However, we took level on the parapet wall and marked the path in the garden.
After marking the path, we placed the concrete slabs one after one. And we completed the path making.
What Mistakes I’ve Made Making The Walkway?
I’ve made two mistakes.
One is I kept four inches gap in between concrete slabs.
We thought that we will plant grass in these gaps. When the grass will grow, it’ll make the walkway even and beautiful.
But that didn’t happen.
These gaps made the walkway difficult for jogging or walking.
The second mistake we made is that we put the concrete slabs three inches above the garden soil.
The thought was, the grass will grow and make the slabs and grass level same.
But this didn’t happen.
We found that there is a possibility of accidents during walking because of the different level of the walkway and garden soil.
So we decided to reduce the distance between garden soil and walkway top level.
How We Remade The Walkway in The Rooftop Garden?
We rearranged the walkway to eliminate those mistakes.
We decided on two things.
The first one is, we’ll keep half inch gap in between slabs.
The second thing is, we will keep the distance between garden soil and walkway top not more than half an inch.
To do these two things we needed to rearrange the walkway slab and we did so.
This is a new experience for me. I’ve now learned from these mistakes.
These mistakes cost me money because I needed to employ many workers to rearrange the walkway slabs. It definitely increased the project cost.
I thought I should share this experience with my readers. So that they can learn from my mistakes as well as cut the extra expenses in their projects.
So, the final thought is, when you make a walkway in the rooftop garden, keep two things in mind.
One is, don’t keep a large gap in between walkway slabs. And the second thing is, keep the walkway and garden level nearest to reduce the accident.
The ultimate purpose of making a walkway in the rooftop garden is to make the path easy to walk or jogging as well as to increase the aesthetic look if the garden.
