Adjustable floors with their own hands
The construction industry does not stand still for a day. Every year new inventions and innovations appear in this sphere, allowing to take a fresh look at the seemingly well-established methods of repair. So, along with the traditional methods of leveling floors with the use of different types of screed, a new way of creating smooth floors for a variety of finishing coatings - adjustable floors has appeared.
Easy benefits of
With the use of adjustable floor structures, you can achieve an even horizontal surface in virtually any type of room in any configuration. It is worth noting that the adjustable floor system is a light enough structure that can be applied without loading the floor. This problem is especially relevant for light individual buildings or for housing built on wireframe technology.
What the adjustable floor
consists of The essence of the adjustable floor system can be described as a hard coating, the position of which can be adjusted using special mechanical devices. They can raise or lower the sections of the floor, maintaining its ideal horizontality.

With this innovative approach to floor construction, it is possible to install a horizontal surface in almost a couple of days.
The use of adjustable floors leaves between the base and the surface a technological space that can be used for transporting communications, or filled with heat-insulating material.
The design of the adjustable floor is rigidly fixed to the base, ensuring its reliability.
On leveled adjustable floors, you can immediately lay the final floor covering, and you can not use an intermediate substrate. This approach significantly saves the cost of the entire design entirely.
An additional insulation material located between the supporting beams of the adjustable floor.
The expected lifetime of the regulated floors is about fifty years, which is quite enough for most types of buildings. In addition, the ventilated plane between the base and the working surface increases the service life of the main overlap and can serve as an additional element to protect against unexpected floods.
Qualitatively installed adjustable floor absolutely does not creak at daily operation. In the process of service, they permanently maintain their horizontal position for a long time.
An important advantage of adjustable floors is their low cost, which is only one third of the price of the traditionally used screed from cement and sand. However, the difference in value between domestic and foreign designs is in fact not very great.
Varieties of adjustable floors
There are two main types of adjustable floor systems, which differ in design and features of their application.
- The first type of system is a solid chipboard, which is based on adjusting devices made from a particularly strong polymer material. Such floors are usually installed in new homes and the height of the field when using such a construction is not more than 5 centimeters. Such minimal technological space, nevertheless allows to lay under a floor various communications or a thin layer of thermal isolation.
Adjustable floor, leveled with strong plywood.
- The second type of adjustable floors are constructions laid on parallel lags. The self-adjustable floor is a multi-layer cake and its feature is a strong fixation of the floor structure to the floor and careful adjustment of the horizontal surfaces. Such a method is suitable for leveling floors in old structures, as well as for equipping rooms with high ceilings, with the arrangement of which requires the laying of utilities under the floor surface.
Adjustable floor created using
logs. With the second approach, the advantage is the firm fixation of the structure with floor overlap.
Alignment algorithm for the adjustable plywood floor
When using this type of floor, the anchor bolts are installed directly into the prepared holes. As coating plates, a GWP sheet, a DSP board or plywood sheets can be used.
- First, a hole is drilled in the coating sheet, into which a sleeve with an internal thread is installed on the back side. Calculation of the distance between the holes is determined based on the planned load.
- Support bolts are screwed into the installed bushings, which are made of especially strong polymeric materials.
- Place the assembled structure on the base of the overlap and attach the adjusting bolts to the base.
- After this, using the building level, level the horizontal plane of the adjustable floor.
- In the event that part of the floor remains sticking out above the floor surface - cut off the protruding parts.
- The next part of the flooring is laid flat on the leveled layer. Make sure that the joints of the plates of the first layer do not coincide with the joints of the next layer, use the same principle that is used in the formation of brickwork.

After laying the adjustment layer, you can proceed to placement of the finishing floor coverings of any type.
Adjustable floors with ladders
With this type of adjustable stripes, ready-made kits produced by different companies can be used. In this case, ready-made sets of adjustable floor systems can be used on any type of base and floors with a variable level of height can be constructed.

Also, as well as floors with a base in the form of bolts, adjustable floors with lags are also equipped with rotating bolts that regulate the height of the floor in its entire area.
The algorithm for constructing such floors is as follows:
- The adjusting bolts are installed in bushings mounted in the logs through the gap defined in the design.
- Then the logs are placed on the floor.
- To the overlapping of the lag is fixed with self-tapping screws or dowel-nails.
- The lag is then leveled using a laser level.
- The parts of the adjusting bolts protruding above the surfaces of the log are cut off.
- Then on the logs the rough floor is laid, on which the final floor covering is placed.
