Leveling is one of the most basic steps in flooring. For this, a wet screed is traditionally used. But in some cases, the most rational solution is the use of a dry mix. This is not only easier, but also faster.
Dry floor fills
Until recently, expanded clay was the most popular backfill material, which has a low level of thermal conductivity and low cost. But at the same time, it also has disadvantages: a large height of the backfill layer, difficulties with surface compaction, etc. In addition, expanded clay sand is not suitable for laying prefabricated floors, since it settles over time. This violates the overall level of coverage, as its elements deteriorate for this reason. The high-tech products of Knauf, which replaced expanded clay, were able to solve this problem.
Dry filling "Compevit"
Dry filling (manufactured by the Republic of Belarus) is an effective insulation for prefabricated floors. Used to level the surface. This material differs from ordinary expanded clay in structure. It does not use crushing, thanks to which there are a number of unique characteristics:
- round granules;
- granulometric composition;
- certain fraction and density.
The material is packed in paper or polypropylene bags of 40 liters.
Benefits of using Compevit floor filler
This screed in the construction industry has been used relatively recently, but has already gained considerable popularity among specialists and home craftsmen.
Among the main advantages of the dry floor system are the following:
- Efficiency of laying - on average, within 8 hours, a team of 2 people lays 50-60 square meters. m coverage.
- It is possible to carry out the installation of the finishing layer immediately after the installation of a dry screed.
- Due to the light weight, minimal loads on floors and foundations are created.
- Compevit dry backfill and prefabricated floor structures allow you to make an impeccable foundation. It can withstand point loads of 360 kg/m2 and operational floor loads up to 1 t/m2.
- Dry screed is used in the arrangement of heated floors, including existing wooden bases.
- The absence of dirt from mortars and cement dust, a long drying process are important arguments for any owners.
- During the entire period of operation, floor breaks and squeaks are excluded.
- Thanks to the good sound and heat insulation performance of the filling layerthere is no need to use additional materials that provide low thermal conductivity and absorb noise.
- Compevit backfill is a hypoallergenic and safe product for human he alth.
- The low price allows it to be used for processing large areas. You can buy material inexpensively in bulk from the manufacturer or at Leroy. Backfill "Compevit" costs an average of 250 rubles. per bag. Given all the advantages of the material, it is not at all expensive.
Scope of application
Compevit backfill is widely used in new buildings. It is used for the following purposes:
- floor leveling;
- increase sound insulation;
- reducing the likelihood of deformation during shrinkage of the building.
Compevit backfill is the best solution for private construction, since the load-bearing structure, foundation and wooden floors experience minimal loads in this case due to the low bulk density of the material.
It also allows you to make repairs in living quarters while they are in operation. During the reconstruction, the floors can be released from the furniture gradually. At the same time, it is permissible not to remove the old flooring, which avoids the problems associated with the disposal of dismantled materials.
How to work with Compavit
The procedure is as follows:
- First of all prepare the base. To do this, it is cleaned of residuesdirt and dust. After that, the estimated level of the future floor is marked on the surface of the walls.
- Cover the base with plastic wrap, glue the joints with the walls around the perimeter with edge tape.
- Distribute the backfill layer, the thickness of which is 2-5 cm, and carefully level it. To obtain one centimeter of layer per square meter, 10 liters of dry material will be needed. The required thickness of the backfill is determined based on the quality of the base surface, what are the height differences and their number. Also affects the availability of utilities and other equipment, their features. It is important to remember that the minimum backfill thickness is 2 cm.
- If the dry screed device is made in a room with high humidity, it is recommended to treat the upper part of the backfill layer with a hydrophobic composition.
- Carefully level the filler layer and begin the installation of floor elements.
Adequate price ensures the popularity of the material. And the good quality of the bulk backfill "Compevit" guarantees a long service life of the rough and finish floor.
