How to insulate the floor in the basement Floor cleaning

Floor insulation is the most important procedure that needs to be done anyway, since If you make a room for visitors (cafes, bars, and so on), then it will be unpleasant for them to walk on the cold floor. The floor should be warm in any case, and the walls in the basement most likely will not freeze, as the basement is under the building, that is, in the ground. Even ordinary heating used by the entire building is enough to heat the walls.

And for this, you need to determine what is your floor in the basement - already filled with concrete or there is nothing on it, that is, bare ground. If your floor is filled with cement, half of the work has already been done for you. But if you have a bare ground, you will have to work a little on it. To do this, you must first fill the entire surface with rubble, and pour sand over the rubble.

Thus, you will have a kind of “cushion”, which you just need to fill with cement. And of course, it is worthwhile to take care that the floor is even and without various unnecessary objects, such as stones or rubbish, as they will only interfere. But still, if this happened, then try to get rid of this problem, for example with a regular knife.

Now fill it with a thin layer of cement (about 4 centimeters) and let it dry for about a day (the drying time depends on the type of cement, ask the seller or read on the bag with cement itself).
