Thickset laying method

There are two main types of Thickset laying :
– with bonded bed mortar
– with floating bed mortar

Our sales team is at your disposal to draw up a prescription adapted to your site according to your specific needs or for any technical question.

The flatness tolerances of the substrate are less than with a glued installation. It is rarely necessary to level the surface. Thus, at this stage, only a verification of the support is necessary (moisture content/drying time, resistance to tearing…).

This type of laying is only suitable for surfaces where the construction deformation is minimal, i.e. where the contraction of the concrete is insignificant, such as: old floors with no risk of contraction/deformation, domestic floors or old industrial floors built directly on the ground. It is not recommended for new floors.

The thick set laying with floating bed mortar is recommended for floors exposed to temperature changes, risks of subfloor shrinkage and risks of structural deformation, such as industrial floors or upper floor areas. On slabs,  thick set laying with floating bed mortar can be carried out approximately three weeks (in new construction) after the subfloor has been laid, as with a thick set laying with bonded bed mortar.
This type of thick set laying is the most frequently used today.

Special care must be taken when treating the specific points (connection with a drains or gutters, pipe passing through the floor, floor/wall connection, overhangs, etc.). Contact your sales representative for more information – page Contact.
