How to insulate the foundation of a ready-made house on your own?

If you have purchased an old wooden house, then special attention should be paid to the foundation. Previously, in villages, in some cases, the foundation was laid on a dense layer of sand, which had a shallow depth. And it turned out that the foundation itself was high, looked beautiful, but was not buried deep into the ground. That is why in winter, when the ground freezes, cold air enters the basement and the floors in the house are cold in winter. In this case, it is necessary to insulate the foundation so that the floors in the house are warm even in winter.If the house is already fully built and there is no way to enter the basement, then the foundation will have to be insulated from the outside. Some builders recommend using this method. On the outside of the house, close to the existing foundation, dig a trench to the depth of the freezing of the soil, and its width will be one or one and a half bricks, depending on how wide you plan to increase the foundation. Then the trench is filled with slag, crushed stone, broken bricks and other building materials that are at hand. Everything is filled with cement mortar. After the mortar hardens, the brickwork is laid on it close to your foundation. At the same time, this insulation does not have to be caught up to the very top if your foundation is high, but rather laid out at a height of 30-40 cm to protect the foundation from meltwater, snow and rain.If you have a regular foundation, but you want to insulate it anyway, then first of all it should be exposed and cleaned, and for this, too, a trench is dug around the perimeter of the house. If required, the walls are leveled, then waterproofing material is applied, and then insulation. The top layer of insulation above the ground surface should rise by 30-40 cm.If you can enter the basement, then you can insulate the foundation from the inside with expanded clay. This option is also advantageous because expanded clay is one of the cheapest materials. At a distance of 35-45 cm from the foundation, a formwork is made, and expanded clay is poured into the resulting space. Loose boards, sawmill trimmings, pieces of slate or other materials that can withstand a layer of expanded clay are suitable for formwork. The space that will be between the expanded clay layer and the floor can be filled with mineral wool or other insulating material. รหัสโปรโมชั่น1xbet
