Is your concrete patio uneven in places? Has it started to crack and look unpleasant? This is something that happens often.
How to fix an uneven concrete patio?
There are several methods. But the one suitable for you depends on your budget and the level of damage it suffered. To level big patches, slab jacking and polymer slab jacking are used. But for smaller areas, veneering and patching show better results. You could replace the whole patio if you want.
These are the ways you can explore to solve your problem. But if you want to know more about them, read along as we have explained every process in a detailed fashion.
Why Does Concrete Patio Get Cracked & Uneven?
Concrete is a very popular patio material. It looks great when it is new. Also, it is quite cheap.
But it goes through a lot of weather changes. Wears down due to erosion and settlement.
The soil under the patio loses moisture and settles down. The concrete patio doesn’t get enough support. As a result, it cracks and becomes uneven.
Also, improper installation and unbalanced mixture can be the cause behind it too.
Pouring the concrete on a hot day will not give the concrete enough time to cure.
As a result, the cement will crack sooner than expected.
Solutions That You Can Consider
Whether it’s due to time or it’s because of human reasons. The situation at hand is the patio is uneven. And there are a few methods that you can try out. The methods are simple as tiling an uneven floor.
These methods differ from each other depending on two things. Your budget and the scale of damage.
Let’s check out the methods below:
1. Slab Jacking
This method requires professional supervision and industrial tools. This process is injecting concrete directly under the places where the solid had shifted. Raising the concrete patio as necessary.
This process is time-consuming as the cement needs days to dry. And you won’t be able to DIY this one.
An improper ratio of the mixture can cause this process to fail soon. So make sure you have the right ratio of the mixture and it gets enough water and time to bond.
2. Polymer Slab Lifting
This method is also done by a professional. You basically have to drill holes at convenient places and inject polymer foam.
The polymer foam fills the void between the solid and concrete. It also raises the concrete as it’s being filled up.
Polymer is cheaper than cement so this is a budget-friendly method. Also, the polymer takes a few minutes to dry so it’s quick.
This method is used when the damage isn’t very big on the scale.
In this method, you basically cut a small portion where the concrete has sunk. You lift the concrete and fill the gap with sand so that it levels.
You patch the hole with concrete and make sure to seal it. Without sealing, water might get in and wash away the sand.
Veneering is just pouring concrete over the existing patio. This way you level the patio but add more concrete over it.
Your first step is cleaning the concrete patio. Brush off any excess debris.
Then you rough up or drill holes in the patio. This way the new layer of concrete sticks better.
5. Replace The Concrete Patio
This is the last resort for fixing your patio when the damage is significantly large.
You have to remove the whole patio. Where the soil sinks, you have to add more sand to level the ground.
You have to give a wooden boundary all over the patio and then pour concrete. Let it dry and soak it from time to time so that the cement hardens.
Check with a spirit level from time to time to check if the patio is level. We have some suggestions for you about the spirit levels you can use. They are listed below:
I hope this spares you the headache of choosing a spirit level.
After you’re done, and if the mixing is right, you should have a new patio that will last long.
Few Tips That Will Come In Handy
Concrete patios need time and water to bond. Lack of water makes the bonds vulnerable and it breaks easily.
So, when you’re laying the concrete for your patio, make sure the day isn’t very hot. Or it will vaporize the water and the bonds will be weak.
Also, soak the concrete often with wet fabric for a few days to ensure it’s properly bonded.
Make sure to incline the patio slightly away from home. This ensures that water will not be trapped in your patio.
To make the patio last longer, you could make an insulated shed over the patio, which will save it from direct sunlight and water.
That is it! Now you know your options and which suits you best.
Question: Is rain bad for your patio?
Answer: Raining itself isn’t bad for your patio but if the water gets stored then it might cause some problems. This can cause the water to seep in and the soil soaks it in. This can cause uneven patios, even cracks. It is better to have a proper drainage system.
Question: How long does it take concrete to dry?
Answer: It takes about 20-30 days for concrete to dry completely. But the first 7-10 days are very crucial.
You should be careful about how much wind exposure it gets. Also,you need to supply it with adequate water. If the sun is too hot at that time, you need to cover it with something so that the water doesn’t evaporate.
Question: Can I use any cover for my concrete patio?
Answer: You can use wax polishes to make your concrete patio shine. It also shades your patio during the summertime from the scorching sun above.
That is our take on how to fix uneven concrete patios. We hope, now that you know your options, you can take an educated decision on what would be best for your patio.
We hope you can make your patio good as new!
