Learn more about Chainage

Chainage is a cornerstone in your renovation work. This horizontal reinforced concrete structure, integrated into your walls, provides them with essential rigidity to prevent cracks and ensure the stability of your entire building. During renovation, chainage plays a crucial role, consolidating foundations and offering a solid base for your decoration project. Whether you plan to open up a room, raise walls, or completely redesign your space, chainage will be your ally in guaranteeing the longevity of your alterations. Beyond its technical functions, chainage can also become a design element in its own right. Depending on the style you wish to instill in your interior, you can choose to leave it exposed, in raw concrete for example, for a trendy industrial atmosphere, or to conceal it behind a stone, wood, or plaster facing for a more traditional finish. Whatever your choice, chainage will harmoniously integrate into your decor.

Frequently asked questions

When creating an opening or underpinning, the chainage is essential to support loads.

Yes, it can remain visible or be integrated into the wall thickness depending on the desired aesthetic.

The chainage runs the entire length of the wall, while the lintel only supports the load above an opening.

The height of a chainage is generally between 20 and 25 cm. This dimension ensures good structural stability while avoiding taking up too much space in the wall.

Yes, the chainage impacts wall insulation. It creates a thermal bridge in the structure, thereby reducing insulating performance. It is therefore important to carefully calculate its position and treat it correctly to limit heat loss.

Chainage is generally made of reinforced concrete, with steel bars ensuring its strength. Sometimes, fiber-reinforced concrete or prefabricated reinforced concrete blocks can also be used to facilitate installation.

When installing a chainage, ensure it is perfectly aligned and level to guarantee overall stability. Additionally, it is important to respect concrete drying times before continuing work.

Chainage is generally integrated into the mortar joints of brick or concrete block walls. It can also be poured into cavities designed for this purpose, to form a solid and monolithic unit.
