How to lay a dry floor screed with an insulating layer of expanded clay

To create a floor screed, materials of a different nature are used. Depending on this, the screed can be wet or dry. In the second case, products are used that do not require fixing to an adhesive compound or building mortars. The dry screed can be combined with an additional insulating layer. For example, made of expanded clay.

1. How to prepare the floor for work

In order to lay a dry screed efficiently, the rough surface should first be rid of old materials. The rough base under them should not contain traces of mold, cracks or other damage. When they do show up, they are necessarily eliminated. Special attention should be paid to the joints between the floor and the walls. If cracks are found somewhere, they need to be filled with a cement-sand composition or strips of foamed polyethylene for insulation.

2. How to prepare logs for dry screed

Lags are the basis of the entire structure. To create them, you need to lay 8-10 cm thick beams across the floor. And at the same time, it is important that their upper planes are everywhere at the same level, otherwise the screed will not be smooth.

3. How to lay the insulation material

To ensure a good level of insulation and at the same time sound insulation, medium-grade expanded clay should be used. It is quite easy to distribute the material over the work surface, and its insulation parameters are high.

Expanded clay is laid in the free space that is present between the logs. The expanded clay layer is lifted to the upper plane of the lags. That is, as a result, a layer should be formed, the thickness of which is up to 10 cm. This is enough for the floors to trap heat and keep out noise.

The expanded clay itself does not need additional waterproofing. However, if the owner wants to protect the floor slab from contact with moisture, he can lay such an insulating layer.

4. How to lay the flooring on expanded clay

Naturally, it will not be possible to lay a floor covering on the expanded clay itself. You need to form a base for it using OSB panels and other wood slabs, as well as a board – ordinary edged or tongue-and-groove. The selected material is placed randomly on the logs. The edges of the slabs or boards must also be on the beams, and not hanging loose.

Such a screed has good strength qualities, but most importantly, it provides decent insulation. Having laid it correctly, you will not have to experience any problems with installing the floor covering later. Many beginners want to gain an advantage right from the start of their betting career.
