What is disabled concrete?
Deactivated concrete is a traditional concrete base, i.e. cement, gravel (or aggregate), sand and water. This concrete is by far the most used in civil engineering and is part of the decorative concrete family. It is found in applications and uses as diverse and varied as:
- Road pavers;
- The terraces
- Gas stations
- Shopping malls
- Some car parks
- Public squares
- Spaces reserved for sport
- Pedestrian areas
- Ramps, etc.
Deactivated concrete easily adapts to any environment. This decorative concrete is an excellent non-slip coating due to its granulosity.

Also called washed concrete, deactivated concrete takes its name because of its pouring technique. It is disabled in the sense that the surface layer of surface mortar is removed to bring out aggregates or gravel.
The proportions of the deactivated concrete must be particularly well respected for the strength of the structure but also for its aesthetics, which remains the reason why one chooses a deactivated concrete rather than another type of concrete. These proportions are respectively, for 1 cubic meter of concrete disabled :
- 300 kg of cement;
- 800 kg of aggregate;
- 400 liters of semi-fine sand;
- 160 liters.
Advantages of deactivated concrete
Deactivated concrete has many advantages, both structural and aesthetic:
- This disabled concrete admits many customizations;
- Choose the thickness of the gravel, textures, colors and hues;
- Outstanding resistance;
- Recognized longevity and durability over time;
- Adaptable to pedestrian areas as well as vehicle areas;
- Decorative product, non-slip;
- Available at low prices;
- Quick to implement despite a pose technical;
- Easy maintenance;
- Can be combined with other decorative concrete;
- Prevents the appearance of weeds.
Laying concrete disabled
Deactivated concrete requires specific laying. Technical requirements must be met in order to guarantee the soundness and rendering of the structure.
Whether it is for a courtyard, a house terrace, for a driveway or a play slab in the garden, so it will be important to adhere to the prerequisites of laying and pouring well. Professionals exist and help you design and implement your project : use their expertise if you have any doubts.
Install the deactivated concrete in a few essential steps :
- Soil is prepared according to traditional methods;
- The pouring of concrete is done as for a concrete classic;
- Levels are checked at the spirit level;
- The surface is smoothed to the ruler;
- Manual smoothing of the surface;
- Application of deactivator : acid erode the top layer of concrete;
- Wait for concrete to take;
- Wash surface: mortar jumps, water pressure exposes gravel /aggregates;
- The surface is sealed with resin (optional);
- You appreciate the result: a very aesthetic rendering.
The deactivated concrete offers many finishes: the size of the aggregates and the shades are combinable to infinity, for renderings that come closer to works of art! Some results are spectacular and deserve jobs in more extensive fields than conventional civil engineering. Opting for deactivated concrete means choosing a coating at low prices, stronger than cement andnon-slip.
