What type of Concrete is best for Garage Floors?

Building a long-lasting, high quality and neatly finished garage for your home is well worth the investment. Not only will it add a handy and sizable bit of extra storage space to your home, but it will also significantly increase the value of your property too – it definitely ticks all the boxes. 

As you construct your new home garage, laying down the concrete floor is one of the trickiest parts of the process, as you will need to decide which variety of wet concrete is the right choice for the job. 

What will the Garage Floor need to be like?

The floor will need to be sturdy and hardwearing (particularly if you plan on parking heavy vehicles in there), and be able to hold its own against cold weather for when concrete is poured. There’s no need to worry though – by planning your build, considering the right type of concrete for the job, and enlisting the services of a first-class commercial concrete contractor, you will be able to secure yourself a superbly finished garage floor that will last for decades. 

What type of Concrete for Garage Floors actually works best?

Below, we’ve provided a round-up of options, to help you confidently decide what type of concrete is best for your garage floor with ease.

Type C30 / ST3

Varieties of standardised prescribed concrete are popular choices for garage floors. Type C30 / ST3 is most commonly used for domestic applications that only require a light duty. As such, it is often used for house floors, or foundations and unreinforced bases for garages.  

Type C35 / ST4

As it provides users with a higher level of strength and durability, Type C35 / ST4 provides a more sturdy, wearing option for an unreinforced concrete garage floor.  

Type C40 / ST5

Type C40 / ST5 is also widely used in domestic applications. It is the strongest of the ST concrete options, which makes it suitable for garage ground floor slabs. It is also a great option if you require reinforced, suspended or ground-bearing flooring.

C20 / Gen3 / ST1

This type of general concrete is also commonly used for domestic applications, such as garage floors. Type C20 / Gen3 / ST1 can also be covered by a permanent flooring finish (such as carpet). 

Reinforced Concrete

If you opt for reinforced concrete for your garage floor, your best bet would be either RC20/25, or RC28/35. These varieties are designed to cope well under exposure from the cold and last against wear from human tread.

Beyond the factors listed above, the right choice of concrete for your garage floor depends on key considerations like your budget, what you plan to use your garage for, the foundations of your garage, and whether you want the floor to be exposed, polished and sealed once it is laid (however, this design feature is more typically used for a floor inside the house). 

You can avoid the common issues (such as flaking, a dusty finish or cracks appearing in your slabs) that come with concrete garage floors by doing your research, and hiring a dependable, professional concrete contractor.
