When laying slabs on concrete, you’ll need a suitable mix to ensure that your slab is strong and stable. You may have heard that there are three types of concrete: plain, reinforced and reinforced with steel mesh. The type of concrete you use depends on your project’s requirements. Plain concrete is used when the structure doesn’t require much strength; it’s not ideal for laying slabs on concrete because it’s not as strong or durable. Reinforced concrete is used when you want to increase the strength of your structure; this type of concrete should be used when laying slabs on concrete because it makes them more durable and more resistant to cracking. Reinforced with steel mesh is used when even greater resistance against cracking is required; this type of concrete should also be used when laying slabs on concrete because it makes them even more durable than reinforced concrete alone.
The best mix for laying slabs is a simple one: mortar. When you’re laying your slab on concrete, you want to use mortar because it’s going to be more flexible and less likely to crack than cement.
Mortar can be made using any combination of cement and sand, but it’s best if you have a ratio that’s about 1 part cement to 2 parts sand. You can also add other ingredients like lime or clay to help strengthen the mixture further.
If you want something that’s going to last longer than mortar, then you’ll need to use a concrete mix instead. This will give you more strength and durability, but it will also make your slabs heavier and harder for people to move around after they’ve been laid down.
The best concrete mix for laying slabs on concrete will depend on the application. For example, if you want your slabs to be easy to install and require little maintenance, you might choose one type of concrete mix over another. You’ll also want to consider whether you need the concrete to last a long time or be cost-effective.
What is the best mix for laying slabs on concrete?
Concrete is a mixture of cement, aggregates and water. The water-to-cement ratio is important as it affects the strength and durability of concrete. The mix has to be able to withstand the weight of the slab and also cure properly.
In order for your mix to have low permeability, you need a hard wearing mix that can withstand traffic and wear-and-tear.
The answer depends on the application.
This is a question that you need to ask yourself, and it all depends on the application. There are many different types of concrete mix, each one suited for a specific purpose. If you want to use concrete for foundations or slabs, then you will have to consider which type will work best for your needs. For example:
- If you want to use concrete for a foundation then you will need a durable mix that can withstand underground pressure from waterlogging and frost heave (this refers to soil swelling due to freezing temperatures). You should also consider whether there may be any seismic activity in your area as this could cause damage if not properly reinforced against it.
- If you want to use concrete for slabs then there are many different options available depending on what kind of finish and thicknesses are required by the client; however one thing all these types have in common is their flexibility when curing which makes them easy-to-lay and thus popular amongst DIY enthusiasts.
You’ll need to consider whether you want your slabs to:
You’ll need to consider whether you want your slabs to:
- be easy to install
- require little maintenance
- last a long time, and be cost effective
- withstand heavy loads, traffic or high temperatures.
be easy to install
- Be easy to install.
- Be easy to level.
- Be easy to finish.
- Be easy to maintain.
- Make sure the slabs are level.
- Make sure the slabs have proper drainage. There should be enough space between slabs for expansion and contraction, so that there is no cracking or movement of your slab over time due to changes in temperature or ground moisture content (if you live in an area where this is a problem). Also make sure that you can easily get rid of excess water from beneath the slab (either via a drain system or by allowing air flow through weep holes). This will help prevent mold growth under your concrete! Finally, make sure that any aggregate used in your mix complies with local building codes regarding fire resistance requirements– aggregates like sandstone may not meet those standards depending on where you live.
require little maintenance
Before laying your concrete, it is important that the surface of your slab is smooth and level. If any cracks are present, they must be fixed before you install your flooring. You will also want to make sure that there are no dusts or dirt on top of the slab as these can cause issues with adhesion. Additionally, if grease exists on the surface of your slab (from cooking or other activities) it should be cleaned thoroughly before proceeding with installation.
last a long time
The most durable concrete mixes are those that use a high-strength cement. The best option for laying slabs on concrete is to use a mix that uses both mesh and rebar, which are strong and durable enough to withstand the pressure of slab laying on top of concrete.
be cost effective
The cost of concrete can vary greatly, depending on the type of concrete used and the amount needed. Concrete prices are generally calculated per unit (a cubic metre or tonne) or per square metre. The latter is usually used when ordering ready-mix concrete by volume and is also most common in residential projects where small amounts of concrete are being used.
We’ve put together a list of factors that influence the final price of your project:
- Type of land – if you live in an area with soft soil, it might be necessary to build a formwork foundation before pouring your slab; this adds to labour costs
- Quantity – larger slabs will cost more than smaller ones; make sure you have your plans fully worked out so you know exactly how much material you need for each step in the process
- Flatness/levelness – if your ground isn’t level enough for laying slabs directly on top, it may be necessary to use some sort of levelling compound under them

Before you can choose the best concrete mix for your project, it’s important to understand the different types of concrete mixes. Each type has its own advantages and disadvantages.
After learning about each type of mix, you should be able to decide which one is right for your needs. If you have any questions about choosing the correct concrete mix and don’t know where to start, don’t hesitate to contact a professional contractor who can help guide you through the process and answer any questions that come up during the building process.
There are a variety of concrete mix types that are suited for different applications
As you can see, there are a variety of concrete mixes that are suited for different applications. The best mix for laying slabs on concrete is the one that is the best fit for your application.
Conclusion
So, when it comes down to it, what is the best concrete mix for laying slabs on concrete? It depends. Hopefully this article has helped you understand a little more about concrete mixes and the applications they’re best suited for.
