You have thought of glazing your balcony and make repairs there, for this you will need to prepare work and purchase material. And not only: you still have to raise the floor of the balcony in the room floors. So more convenient to go to it and it will not be necessary to go down to 20-30 centimeters every time to watch out of the window behind people passing at thenime, etc. Next, we will discuss the process of raising the floor on the balcony.
Preparation for repair
This procedure includes water waterproofing. Concrete from which the balcony is usually made - cold material, has a property to absorb moisture. So that in the future the new floor was not wet, lay insulation. The simplest options are to put the film or process the foundation. bituminous mastic. You can still use dry penetrating mixeswhich also give a good moisture-proof effect.
Methods for changing the height of the floor
What option is more profitable to you to raise the floor, you decide. There are several of them:
- Old and well-known - make a screed from sand and cement. The disadvantage of this method is a lot of weight, the slab of the balcony can collapse.
- The screed with clay is used to significantly ease the mass of the fill layer.
- Dry screed.
- Raise the level of the base with the help of lag.
How to make a cement screed
I first note that you can not work with concrete if it's cold outside. It is necessary that the average daily temperature reached + 10-15ºС. More, the thickness of the screed layer should not exceed 9 centimeters, since the base plate of the balcony may not withstand weights. For the fill, it will take a formwork for the liquid solution to do not flow through the slots. The boards are used as portors, it is necessary to attach them from the outside of the balcony railing. Between the wall and the floor stir damping tapeSo that when expanding the concrete, reduce the pressure on the sidewalls. From the reinforcement at the same distance, make beacons, putting a few cement mortar under them. Level Check: Exactly exposed lighthouses. Let the cement dry. Then fill in the entire base of the balcony with a cement tie, focus on the beacons so that the floor turns out to be smooth. However, many masters work without lighthouses. Initially, they pour the floor with cement mortar, and then align special mix.
Screed with ceramzit
This species is often used by specialists. The process is the same as when floating floors with concrete, i.e. Initially make waterproofing, formwork, then pave a damper tape. Based on the beacons, fall asleep ceramzit, Only the backfill level must be lower than the three centimeters installed. Top poured with a screed.
Dry screed
For a small balcony area builders apply a dry tie. The process of raising the floor at this option is not time-consuming, after preparatory work (waterproofing of the base, sealing slots, styling damper tape) on the floor pour out dry mix. After which it is tamped, and the layer of polyethylene and moisture-resistant Faneru. According to the rules, the coating must be laid in two layers, securing self-stairs. At the end of the work, the tree is treated with varnish.
Changing the floor height with lag
The widely used method, since it does not heat the base of the balcony and there is an opportunity to put the insulation between wooden lags. First, make a grid from the bar of the desired height. It is necessary to take into account that on top on the bars there will be a lining (boards, lining, plywood), so the height of the bars should be 2-3 centimeters below the floor level. After that, this lattice is aligned in terms of laying under the bars of gaskets. Fasten the design to the base anchors. In the lattice laid insulation, Top with the treated with oil, boards.
Now you know what ways you can lift the floors on the balcony, and what materials are used for this. Decide to you for the method of raising to apply.
