Concrete slab: what is it and what is it for?

A concrete screed can be used in different circumstances. For example, it is used to pour the foundations of a house or a garden shed . But it is also used when installing a swimming pool, a terrace or a garage . Its good realization is important, because of this one will depend your construction. It is particularly important if your slab is used as a foundation for your house because it will guarantee the security of your home.

The screed or slab is therefore a flat surface which will be covered with concrete and will serve as a support for your floor . On the one hand, it will allow you to install a coating, such as parquet or tiles. On the other hand, it will also be useful for insulating your construction. Note that it usually flows over the plumbing.

For all these reasons, pouring a concrete slab is a must when you are building or renovating a home.

How much does it cost to install a concrete slab?

The cost of installing your screed will depend on different factors . Among them are its size, the type of concrete, the preparation of the site and, of course, the manpower that will carry out the installation.

Installation without professional help

If you have some knowledge of masonry and you already have good experience in this type of work, you can make your concrete slab yourself. This will allow you to save money. In this case, the price of pouring the screed will be equivalent to the cost of the material necessary for its realization. We can estimate this at around 45 € per square meter , depending on your equipment and the surface area to be poured.

Take the example of a screed of about 20 square meters.

First, you will need to check that you have the necessary equipment, such as a concrete mixer and shovels . If you don’t have them, then you will need to rent them. Count around € 30 for the daily rental of the concrete mixer (or € 200 for purchase) and around ten euros for the shovel.

Then, of course, you will have to buy all the necessary equipment to make your concrete and pour it . This includes the purchase of shuttering boards, mesh for reinforcement, geotextile film, and of course, bags of concrete. The quantity and price of your material will obviously depend on the surface you want to cover. In our example, count approximately:

  • € 5 for a 40kg bag of sand ;
  • € 10 for a bag of concrete ;
  • € 25 per square meter for the geotextile film ;
  • € 5 per square meter for reinforcement ;
  • About € 7 for a formwork board .

Before you start, the easiest way is to make a list of all the materials and equipment you will need depending on your surface. This will allow you to know the total cost of your concrete screed.

Installation by professionals

As we have already explained, a concrete slab is a fundamental support of your construction. So, if you are inexperienced or unsure of your skills , it will be best to bring in a professional masonry professional to guarantee the job. An experienced mason will easily have the necessary equipment and know-how to pour your screed.

In order to know the amount of the installation of your slab, it is preferable to ask for quotes from several craftsmen. This will allow you to compare well and adjust your choice to the one that best suits your budget.

Know from now that, compared to an installation by an individual, that made by a professional will cost around 20 € more per square meter . In the case of our example, this would drop the cost to around 65 € / m². Of course, this cost is indicative and will depend on the size of your screed (the surface but also its thickness), the technical complexity required for your type of concrete and, finally, the preparation of the ground. The latter will be different if it is an interior or exterior site.

It is also interesting to know that, for slabs larger than 40 square meters, the final cost will be higher . On the one hand, because the quantities of material needed will of course be greater. But also because for such a surface, your professional mason will have to resort to heavier machinery. This will logically increase the price of installing your screed.

The importance of preliminary research

Before you start pouring your foundations or your terrace slab, it is therefore important to analyze the situation in order to make the right choice. Carefully measure your surface to be covered, check the necessary ground preparations and ask for quotes from several craftsmen.

If you are an experienced handyman, you will be able to compare the total cost of the materials you will need with professional quotes. If, for warranty and safety reasons, you prefer to use a masonry company, you can compare the prices of different craftsmen in your area. Be aware, however, that it is very rare to make a concrete slab for a budget of less than € 1,000 if it is made by a professional .

In any case, it is strongly recommended to go see craftsmen and explain your project to them. This will allow you to find the most satisfactory option in terms of budget, time and quality.

Remember that if your concrete screed will serve as a foundation for your home or your future swimming pool, the excellence of its installation is essential . Indeed, it will support your construction, and the security and sustainability of your home will depend on it.
