Sometimes the owners of houses have a need to fill the screed directly on the ground. This work is quite complicated, so you need to approach it extremely carefully. If the procedures are completed correctly, it will be possible to form a reliable basis for the floor covering.
Preliminary work in this case is that the soil itself is cleared, on which the screed will be laid. There should not be pollution or any garbage in the soil.
Follow the level to which it is necessary to raise the screed. For this purpose, a horizontal line is outlined around the perimeter of the room. It should be built in level so that subsequently there are no distortions of the screed.
Further actions suggest that expanded clay is poured on the ground. It needs to be filled with an even layer and additionally tamp it so that such a spit is very durable. Sand is also poured onto expanded clay, which is also compacted.
Then they begin to fill the concrete mixture, which is designed to finally strengthen the screed and create a surface to lay the flooring. The formed screed is durable and reliable. Therefore, almost any finishing material can be laid on it.
