How to make the floor insulation in the garage

For the insulation of the floor in the garage can be used different materials. But the main ways to perform this procedure, there are only two:

  • wooden flooring on the logs using insulation;
  • laying insulation and pouring over the concrete screed.

Basic rules for assembling wooden floors in the garage

According to the norms of SNiP, when designing garages, the choice of materials and methods of their installation should be made taking into account the load on the floor at 400 kg / m2. Therefore, when assembling the flooring in such structures, you need to follow some rules.

It is believed that when used for mounting the floor in a garage, 2 cm log boards should be placed 30 cm apart from each other. And under them it is necessary to use boards with a section of 5x15 cm.

When using sawn timber with a thickness of 3.5�4 cm, it is allowed to mount logs in increments of up to 50 cm. In this case, the board is also allowed to use a board 150x50 mm. But it is better for such a flooring to still take the bar 100x100 mm.

Wooden floors in garages are usually not strictly horizontal. Flooring for ease of cleaning knock with a slight bias towards the gate. At the same time, it is taken into account that, at the entrance, the coating must lie flush with the threshold. Indeed, otherwise it would be just inconvenient to drive into the garage by car.

The steps of assembling wood flooring with your own hands

Mounted insulated floors of this type in the garage according to the following technology:

  • slightly deepen ground floor (about 20-25 cm);
  • pour concrete or lay brick columns, supports under the logs;
  • align and compact the ground between the posts;
  • make dumping with rubble 5-15 cm;
  • lags on poles are attached;
  • the space between the pillars is covered with a hydro insulator;
  • the ruberoid is filled with expanded clay in lag level;
  • stuffed on the supports of the board;
  • finished floors are painted or varnished in several layers.

Of course, to warm the floor in the garage, instead of expanded clay, you can use any other, more modern insulators - mineral wool or, for example, expanded polystyrene.

Installation of columns

Support under the logs are usually poured from concrete. Before they make a markup.Further, digging holes about 40x40x40 cm under the bollards. Sand is poured into the bottom of the pits with a layer of 5 cm with tamping water. On top of the sand is placed crushed stone with a layer thickness of 15 cm.

Fill the pillars under the lag with a solution prepared in the proportion of cement / sand / gravel as 1 * 3 * 2. In the pits install formwork of chipboard or boards, vymeryuya horizontal level.

Next, assemble the reinforcement cages. You can make them for each column of several rods and wire. At the final stage, concrete solution is poured into the posts. It is allowed to lay logs on the supports made in this way no earlier than after 2 weeks.

Brick columns lay out under logs in the usual way with bandaging of seams. The formwork in the pits in this case is set so that it protrudes about 5 cm above the ground.

Assembly lag

Before laying the log under the wooden insulated floor of the garage, the posts should be covered with two layers of roofing material. Perform installation of supports for wood flooring as follows:

  • stack the two most extreme lags in opposite walls;
  • pulling between them approximate cords;
  • mount intermediate lags.

In order to avoid a large difference in the heights of the supports, for example, well-dried wooden wedges can be used as a lining. Fix the logs on the posts, usually with metal corners and dowels. To prevent the floors from beginning to creak, it is desirable to fix the supports in this way from two sides.

Laying of roofing material and installation of insulation

In order for the soil moisture not to have a further negative effect on the insulation, the space between the columns after installing the lag and dumping with rubble and sand should be laid with roofing material. Along the perimeter of the garage, this material should be mounted with an overlap on the walls. Over roofing material equip the warming layer. Expanded clay while falling asleep between the lags.

In the same way, they install the mineral wool or polystyrene foam. At the final stage, the laid heat insulator is covered with roofing material directly on top of the lag.

How to Floor

To assemble the cover itself in the garage, you can use either a sheet piling board or a regular edged board. In the latter case, the nails are stuffed just over the boards. The grooved material on the logs is fixed using a screwdriver and screws into the groove at an angle. Lay the boards in both cases so that their ends fall on the logs.

So that there is no gap in the flooring later, it is mounted using the following technology:

  • next to the laid board, at a small distance from it, a piece of a bar is nailed to two lags;
  • two wooden wedges are driven in between the timber and the board in such a way as to press it as tightly as possible against the previous board;
  • hammer nails or screw in screws;
  • rearrange the bar for the next board.

The flooring is also mounted in such a way that a temperature gap of about 1 cm remains around the perimeter of the garage between it and the walls.

Pouring concrete floors in the garage

Installation of wooden flooring in the garage, so the procedure is not too complicated. However, as is well known, the floors in such premises are often subject to serious pollution. In the garage can be spilled, for example, gasoline, oil or any means intended for care of the car.

For a tree, contact with similar compounds is, of course, not very useful. Therefore, most often the floors in the garages are warmed by their owners with the use of a concrete screed that is more resistant to chemicals.

In this case, the installation of the floor will look like this:

  • the earthen floor in the garage deepens and settles the gravel-sand pillow;
  • lay waterproofing;
  • heat insulation;
  • establish the reinforcement cage;
  • on some of the supports mounted lighthouses;
  • perform pouring concrete screed.

Arrangement of crushed stone cushion and installation of a waterproofing agent

The layer of gravel under the insulated screed in the garage should be at least 10 cm, and the sand - 5 cm. The thickness of the warming layer will be about 10-20 cm.

After excavation of excess earth, the floors in the garage, as well as when assembling wooden flooring, compact and fall asleep with rubble. Sand is laid on top of it. Both layers are required to ram and level.

The hydroinsulator on top of the pillow is placed in two layers. The overlap between the bands of the ruberoid is made not less than 15 cm. Also, a waterproofing barrier, of course, is obligatory put on the walls to the height of the future pie of the floor.

Installation of insulation

Insulation of concrete floors from cold in garages is usually made using expanded clay. Before filling it over the waterproofing, it is desirable to set up lighthouses.After laying the clay in a layer of 20 cm, the last ones will just need to be removed with backfilling of the space left by them.

Also, the screed in the garage is insulated sometimes with the use of expanded polystyrene foam. In this case, as the insulator is supposed to choose the most dense material. After all, the load on the floors in the garage is actually very large.

Most often under the screeds in such premises is used polystyrene foam brand PBS-C-50 with a thickness of 10-15 cm. Foam for insulation screed in the garage in any case will not work. After all, the material is quite loose.

Plates of dense polystyrene in the arrangement of the floors in the garage are placed on top of the waterproofing butt butt without gaps. For expanded clay, the concrete screed is subsequently poured directly - without the use of roofing felt. Plates of expanded polystyrene are additionally covered with another layer of waterproofing material.

Installation of fittings and screed casting

As with the assembly of wooden floors, the screed in the garage is usually poured with a slight slant towards the door. Reinforcement mesh installed on the halves of bricks or any other supports. Located in the thickness of the screed at the end of the work it should be about in the middle.

Lighthouses above the reinforcing mesh before pouring the concrete mixture can be installed, for example, on the �fungi� intended for fastening the technoplex. To expose such support, of course, need to level.

As the beacons themselves for the concrete screed, a metal profile is usually used. On the line of "fungi", on a par with their cap, first lay a strip of concrete solution. The profile itself is subsequently fixed to it. Next, pour the tie using the rule of sufficient length.

Final finish

To protect wooden flooring or screed in the garage from the destruction of various kinds of chemical means, the finished floor at the final stage should always be additionally covered with pieces of rubber or linoleum. You can also use any other easy-care coating that can trap moisture. Fix the selected material on the floor in the garage should be as secure as possible - using not only glue, but also nails or screws.
