What is deactivated concrete?
It is a technique based on classic concrete which will have been enriched with aggregates . These are gravel or pebbles that can even be tinted according to your tastes or ideas.
The name « deactivated » refers to the treatment it receives after the concrete is poured. Indeed, after pouring the concrete, it is necessary to apply a retarding product. This must dry for 12 to 48 hours depending on weather conditions. Then, thanks to the use of a high pressure cleaner, you will remove the surface layer of the mortar so that the aggregate that you have inserted there appears.
Advantages of deactivated concrete
Deactivated concrete has the same characteristics as conventional concrete. Indeed, it presents:
- Great longevity : it can easily last between 15 and 25 years.
- High resistance : concrete is a material of great strength, which allows it to withstand bad weather very well.
In addition, deactivated concrete has excellent slip resistance thanks to the aggregates incorporated into it. This makes it an ideal material for outdoor installations like walkways or a pool deck. It is also designed to cope with different climatic conditions , such as rain or frost.
Finally, its aesthetic side is enhanced by the aggregates. Indeed, these give the appearance of gravel soil to the concrete. This adds charm to a driveway or terrace, without having the disadvantages of maintaining a real gravel floor. Also, since you can choose the type of aggregate to use, you can customize the rendering of your concrete. So you can choose the level of roughness and the color you want to give to your concrete.
Finally, deactivated concrete is very easy to maintain and clean , unlike gravel driveways.
Laying of deactivated concrete
The first step in laying deactivated concrete is quite similar to pouring a conventional concrete slab. You will need to mix the same ingredients (bag of concrete and water). However, you will have to add the aggregates that you have previously chosen.
The second part of the installation is different. It involves, on the one hand, the handling of a retardant and, on the other hand, the use of a high pressure cleaner to remove the surface layer of mortar.
If you already have some experience in the pouring of concrete slabs as well as in the handling of this type of material and tools, and if you have the necessary tools for the realization of your deactivated concrete, then it is possible for you to ask it yourself.
If this is not the case, we strongly recommend that you consult a professional. This will guarantee you a perfect and secure installation. Indeed, the installation of deactivated concrete requires a certain technical know-how. In addition, the use of a qualified craftsman will guarantee you a durable and resistant result.
Before choosing the craftsman who will take care of your installation, do not hesitate to go and see several of them. You can then compare the services they will present to you in their quote. In general, we recommend a minimum of three quotes in order to have a better overview and all the information needed to make a good decision.
Cost of laying concrete deactivated
It is not easy to accurately assess the cost of installing deactivated concrete. Indeed, many different factors must be taken into account in the calculation of the final cost. Before choosing your craftsman or embarking on the work yourself, it is therefore important to consider the following points.
The surface to be covered
Obviously, the larger your surface, the more concrete you will need to manufacture, and therefore the higher your budget will be.
The condition of the starting field
Depending on the state of the space to be covered, it may be necessary to carry out earthworks . This is the case, for example, if your land is sloping or in poor condition.
The objective is to prepare the ground so that it is suitable for receiving the pouring of your concrete. Indeed, it is imperative that your reception surface is flat.
The price of materials
This will depend on the quantity of materials you will need, but also on the quality of these and the type of aggregate you have chosen.
If you decide to do the installation yourself, it is quite easy to find these materials at large DIY stores. However, be aware that you may need to hire a van to transport the bags of concrete and aggregate if you want to cover a sizable area. You will then have to add it to your expenses to calculate your costs.
The cost of the material
The material to be used varies depending on the scope of your work. For example, you will need a high pressure washer, a concrete mixer or even a mixer truck depending on the surface to be covered.
Obviously, the cost of the material will be included in the overall package if you have your installation carried out by a professional excavator . But if you are doing it yourself, you will need to remember to include it in your cost calculation in order to know your total budget.
The cost of labor
If you hire a professional to lay your deactivated concrete, the cost of labor will depend on the craftsman you decide to employ. This is why it is important to request several quotes in order to compare costs and services.
The estimate will include the price of labor but also materials, as well as the necessary equipment and tools. Prices are different from one professional to another, but they strongly depend on the surface to be covered. In general, the budgets to be foreseen are as follows:
- For a small area , that is to say less than 50m²: it takes between € 100 and € 150 per m² .
- For a surface greater than 50m² : it will be necessary to count on a price between 60 € and 100 € per m² .
If you decide to do the installation yourself, you will obviously save this expense in your budget.
In all cases, do not hesitate to go and inquire. Compare the options and see which one best suits your desires, your project and your budget.
