In our backyard or in the garden, we plan to construct a concrete pathway for providing a minimalistic look. In the backyard or garden, you will have grass everywhere. Now, you may think about whether you can pour concrete on grass or not and what is the procedure for putting concrete on grass.
First of all, it’s prohibited to pour concrete on grass as it can do immense damage to the structure. You will need to remove the grass from the surface then you will be able to pour concrete for constructing a structure.
Read on and learn how to do construction on the grassy area. So, without any further ado, let’s begin then.
The Procedure of Pouring Concrete on Grass
Directly pouring concrete on grass can do immense damage to the structure. Casting on the grass can cause issues like subsidence, create uneven surface and air pockets, moisture ingression issues, develop cracks, and so on. With time, these can lead the structure to collapse.
That’s why it’s not wise to directly cast on grassy areas or grass. You will need to remove the grass and then start working there. Here are the steps you will need to follow –
Step 1: Remove the First Layer of the Soil
Before pouring concrete, you will need to remove the upper layer of the soil. The first layer of soil consists of debris, trees, weeds, roots, etc. which can affect the base in the future. That’s why, the first layer needs to be removed with the help of a shovel.
Step 2: Prepare the Surface
After removing the first layer completely. use sand or gravel over the entire surface for creating a level surface there. Then you will need to use plastic sheeting all over the area for keeping the concrete base from moisture.
Step 3: Provide Frameworks
Once the surface is prepared for pouring concrete, you will need to provide a framework that will help the concrete to hold its shape. Also, this framework will help to protect the lawn and soil around the area from cement.
You can provide reinforcement bars for getting a strong structural output. The bars also help concrete in binding and it also helps from cracking.
Step 4: Start Pouring Concrete
And now we are in the end game! We have prepared the surface and now it’s time to pour concrete. Here you should use concrete that has a lower setting time and can harden within 24 hours.
So, prepare the concrete, pour the mixture over the area, and wait till the concrete get harden. Then remove the formwork, cure the slab properly, and after 28 days, you will be able to use the walkway or slab without any issues.
Is There Any Situation When Cement can be Poured Directly on Grass?
Though it’s not the right way to do it, there are a few situations when you can directly pour concrete for constructing the base or walkway.
- If you are constructing a thick slab then the chance of regrowth of grass may get stopped.
- If you are planning to build a temporary structure.
- If you don’t have any problem maintaining the concrete frequently.
And last but not least, if you are willing to have an uneven, deformed, cracked surface. Then you can pour concrete on the grass without any issues.
Frequently Asked Questions and Answers (FAQs)
Can I pour concrete directly on the ground?
It will completely depend on the type of soil you have. If the soil is very sandy then you can pour concrete directly on the ground. On the contrary, if the surface has less-sandy soil then you won’t be able to pour concrete directly.
What is the best base for concrete?
Medium-sized gravel is the best base for concrete. It provides a solid foundation for concrete. Using gravel as a base can improve drainage, prevent water from pooling underneath concrete, and so on.
Lastly, for keeping your structure from any potential threat, you should avoid constructing a base or walkway directly on the grassy area. For better output, prepare the area properly, and follow the aforementioned steps. Hope so this guideline will help you out and if you have any further queries, let us know in the comment box below.
