Insulation for the floor: tips for laying. Waterproofing the floor in a wooden house

Insulation for the floor is relevant today for premises of any purpose. If you do not lay the waterproofing layer on the floor, even a strong concrete can eventually lose its performance characteristics due to moisture.

Oak waterproofing

The floor can be insulated with okleyechnymi materials. To do this, you can apply glass refractor, waterproofing, roofing paper, glasswool or hydrobutyl. Work on the laying of the listed materials requires compliance with complex rules. So, the foundation must first be leveled, after this stage the irregularities should not be more than 2 mm. At the next stage, the base should be primed with an emulsion made on the basis of bitumen. As the final and main stage is the implementation of pasting. It is important to ensure that the coating is not damaged. If the insulation for the floor is based on a roofing material, the coating will be strong, but it will have one drawback, which is a toxic smell.

Capillary insulation

Capillary protection of the floor requires the use of a mixture that includes Portland cement, reactive ingredients, and quartz or silicate sand. The composition should be applied to a slightly moistened surface. The strength level of concrete at the same time increases by 20%. As an important characteristic is one feature, which is expressed in the independent healing of cracks.

Insulation with film materials

The insulation for the floor can also be represented by all kinds of film materials, the thickness of which is 0.2-2 mm. The composition of such materials can be PVC, acetylcellulose, synthetic rubber, as well as polypropylene. As a result, it is possible to obtain a coating with increased elasticity and excellent strength. But if you use additional reinforcement of fiberglass, it is possible to provide even more impressive insulation strength.

The described insulation for the floor, which must first be given the appropriate size, should be laid around the perimeter of the room. It is necessary at the same time to ensure the continuity of the coating and its approach to the surface of the walls. If there is a desire to waterproof the floor in an economical way, then a PVC film can be used.

Waterproofing with mastic

The insulation of the wooden floor is necessary, since wood is most susceptible to moisture, you can use mastic for this. It is an adhesive compound that can interconnect all kinds of materials, in addition, it protects the surface from destructive influences. Previously, the technology most often used was that bituminous mastic was applied to the slab. The roofing material had joints, which were treated with the same bitumen. This bitumen coating has significant disadvantages, one of which is expressed in the occurrence of cracks, which makes the waterproofing not so effective.

If the insulation of the floor in the apartment is made with coating materials, then you will be able to complete the work in a short time, without much effort being spent. Lubricants are simply applied, but it must be remembered that after hardening they do not have a special mechanical strength.

Waterproofing of the floor of a wooden house

Isolation of the floor of the first floor in a wooden house is an especially important procedure for the preservation of building materials. Initially, attention should be paid to insulation work in the field of the foundation. As a material for this, you can use the same ruberoid. Then, after the flooring of the rough floor, it is necessary to ensure the laying of the hydraulic barrier, in the role of which it is permissible to apply a dense polyethylene film. A prerequisite is the provision of a ventilated gap between the surface of the rough and the finished floor. Sex boards can be isolated from the effects of moisture by applying a polymer varnish to their surface, after drying, which can be applied decorative coating.

Floor waterproofing on the soil

In private houses, the floor of the lower floors of which is on the ground, there is a need for waterproofing works. The isolation of the floor from the ground in the first stage involves the compaction of the soil at the bottom of the excavation. At the bottom of the pit it is necessary to lay rubble, the granularity of which is 30-50 mm, the layer should be 7-10 cm thick. The crushed stone should also be compacted. Next comes the sand, the thickness of which should be the same. It is permissible to use any sand. After that, you can mount a wooden floor, arranged on logs, or to cover a concrete screed.

Insulation of a wooden floor

The isolation of the floor from the ground assumes, in the case of a wooden system, the necessity of mounting supports for logs. They can be made of brick or concrete. After the concrete has gained strength, its surface must be treated with lubricating material. Top it is recommended to lay the roll insulation. This will protect the lags at the points of mating with the supports. After installing the log, you can proceed to the construction of the rough floor, which can be made of waterproof plywood, it will serve as an isolation. As an additional insulating layer, polyethylene can be used, which is covered with plywood.

Isolation of the floor of the first floor in this case assumes the need for laying the material with an overlap of 15 cm. The joints must be glued using a scotch tape. In addition, foamed polyethylene can be used .

Insulation of concrete floor

In order to isolate the concrete floor on the ground, after laying the "cushion" it is necessary to equip the black screed. After the concrete has gained strength, it is possible to make a roll-up waterproofing on its surface, which is laid in 2 layers. To do this, you can use roofing felt or roofing felt. The insulation on the floor is laid by the burner. After it is possible to lay a heater and to execute one more coupler which will be already fair. There is another alternative solution, which consists in laying 200 microns of polyethylene on the sand. The material is carefully glued in the area of the joints. On the surface of the film is arranged a rough screed, the layer of which is 5-7 cm. In order to protect the concrete screed, the same roll materials can be used. On top of the above technology is covered with thermal insulation, and then a clean screed is laid.

Isolation of the wooden floor, like any other, must be carried out necessarily, otherwise you will after some time come across a lot of problems, for example, with high humidity in the premises, as well as the formation of fungus on the surface of the walls, etc.
