There are two types of adjustable floor: on logs and slabs.

Logs are wooden parallel bars 50x50 cm in size.

This method ensures tight adhesion of the floor to the structure and is suitable for old houses with high ceilings, as well as in those cases where it is required additional wiring of communications.

The second type is wooden slabs fixed with polymer bolts that adjust the floor height. The height from which such a floor can be raised is no more than 5 cm.

  1. First you need to purchase materials and prepare the necessary tools for work:
  • dowel-nails or self-tapping screws; Do we carry out an adjustable plywood floor on logs in a house or apartment with our own hands? Step by step instructions + Video
  • hammer;
  • laser level;
  • polymer bolts;
  • drill;
  • lags.

  1. Think over the layout of communications.
  2. If you have chosen the construction of an adjustable floor on logs, in accordance with the project we drill holes in the bars at a distance of 50 cm from each other and screw in the bolts by hand. The drill can be with a widened tip, and the holes need to be made slightly smaller than the bolts.
  3. Use the special drill bit , Do we carry out an adjustable plywood floor on logs in a house or apartment with our own hands? Step by step instructions + Video to finally install all the bolts in the joists.
  4. Leave a distance of 1 cm from the wall for ventilation and install our structure on the floor.

    If you plan to finish the floor in the form of tiles, then the distance between the logs must be reduced. Usually it is 30 cm.

  5. With the help of self-tapping screws or dowel-nails, the structure is fixed to the ceiling. The drilling depth in concrete must be at least 4 cm. We hammer in the nails properly in order to securely fix the structure to the floor and to avoid squeaks and loosening of the floor during operation.

  6. Level the floor using a laser device. Using a wrench, we adjust the height of the bolts; after work we cut off protruding bolts with a knife or other suitable tool.
  7. The final stage: we install the floor covering on the structure of the logs. As a rule, plywood or chipboard is used as a covering on adjustable floors; it is well suited for further floor covering with linoleum, paint, laminate and other materials.

  2. We make floor markings. Logs in the house, we place the quarters at a distance of 30 cm from each other.
  3. Along the line of installation of the bars, we fix the corners of a given size at a distance of 50 cm.
  4. In order not to have to cut off excess parts of the corners after leveling the floor, select a corner in height less than the level of the primary coating.
