The waterproofing of the floor in basements and industrial premises, in garages and city apartments is made using a variety of materials. This can be, for example, bitumen mastic, special moisture-proofing mixtures, dyes, etc. But most often, roll waterproofing is used for this purpose. For the floor, or rather for its protection against moisture, such materials are simply perfect.
Application benefits
Roll materials among owners of houses and apartments have earned popularity primarily for the ease of installation. To make high-quality moisture-proof covering of the floor with their use, you can do it yourself. Another advantage of this type of waterproofing is its low cost. Moreover, despite the fact that such materials belong to the budget group, they protect the floors from moisture very effectively. A long service life is also what good roll insulators received good reviews from owners of apartments and houses.
Varieties of material
Roll waterproofing for a floor is classified mainly by the method of attachment to surfaces. In this regard, distinguish materials:
- Stickable. This type of waterproofing is attached to the floor surface, usually using bitumen mastic or special adhesives.
- Surfacing. This type of roll material is fixed to the surfaces with a gas burner. At the production stage, a thin bitumen layer is already applied to the reverse surface of the waterproofing agents of this group.
- Mechanically fixed. Such materials are fixed to surfaces using nails or staples.
Roll waterproofing insulators can differ in the type of materials used for the manufacture. The cheapest varieties are made on the basis of ordinary cardboard. That is how they make, for example, a well-known budget roofing material well-known to everyone. In more expensive materials, the base can be fiberglass, fiberglass or polyester.
Products of the Technonikol company
There are several brands of roll waterproofing in the domestic market. But most often, floors and other surfaces are protected from moisture using materials manufactured by Technonikol. Waterproofing agents of this brand are distinguished by simply remarkable operational characteristics. Two types of materials from this manufacturer are mainly suitable for flooring - glued Tekhnoelast Prime and fused Tekhnoelast Thermo. Also on sale is a special self-adhesive membrane of this brand, designed for indoor use.
Good quality at not too high cost is what distinguishes TechnoNIKOL, rolled waterproofing. The price of a self-adhesive membrane of this manufacturer, for example, is only about 1300-1500 rubles. (10 / 0.75 m). The materials of this particular manufacturer are considered a good alternative to a less strong and durable budget roofing material. Their guaranteed service life is 25-30 years.
Glass insulation
This type of roll materials, as well as roofing material, is very often used to protect floors from moisture. Roll waterproofing is made for floors, foundations, roofs, etc. of this type based on fiberglass or mixed. In this case, bitumen is used as an impregnation. The advantages of stekloizol primarily include incombustibility and durability. It can serve up to 15 years if it is correctly laid.
Materials for waterproofing the floor: bikrost
This is also a very popular type of waterproofing in the domestic market, excellent for protection against moisture, including the floor. Bikrost can be made both on a fiberglass and polyester basis. Among its advantages, among other things, include the ability not to lose their properties at air temperatures from -15 to +80 ° C. Polymeric additives are not used in the manufacture of this type of roll waterproofing. Therefore, bikrost does not differ in too good adhesive qualities. However, it costs less than glass insulation and even TechnoNIKOL brand waterproofing agents.
Polyethylene film
This type of waterproofing is also often used to protect the floor from moisture. Technical polyethylene film is best suited for this purpose. Its thickness is slightly larger than that of a conventional one, and therefore it is somewhat stronger. Such material is inferior in terms of transparency to greenhouse, but in this case, of course, it does not play any role. It costs a polyethylene technical film cheaper than usual. Particularly suitable is such a roll waterproofing for a wooden floor. On top of it, usually not too thick concrete screed is placed or plywood is stuffed.
Why do waterproofing floors in urban apartments?
Most often, the floors are protected from moisture, of course, on the basement floors of private houses. Indeed, in this case, there is a very real threat of groundwater entering the room. But sometimes floors are waterproofed in city apartments. In this case, this procedure is carried out mainly in order to completely exclude the possibility of flooding of neighbors from below. Also, roll material for waterproofing the floor in an apartment is usually laid before laying such expensive coatings as parquet and massive board. In this case, the main purpose of the operation is the need to protect the floor finish from warm water vapor rising from the lower floor.
Preparatory Activities
Floors in city apartments in most cases consist of the following structural elements:
- concrete slab ;
- block lag;
- floorboard.
In order to perform the highest quality waterproofing of the floor in the apartment, it must be disassembled right down to the concrete base. This is especially true for residential premises in houses of old construction. The tree has a limited service life, and the condition of the floors in the apartments of such high-rise buildings usually leaves much to be desired. In any case, you should not put a new screed on them.
Installation of waterproofing should only be done on a carefully leveled concrete base. Also, the stove should be thoroughly vacuumed and wiped with a damp cloth. If the coating has a lot of defects, a special self-leveling mixture should be applied to it before laying the roll material.
How to make waterproofing right?
In a city apartment, any of the materials described above can be used to protect the floor from moisture. But most often in this case, membrane materials "Technonikol" are used. Simplicity in laying is what, among other things, differs such a waterproofing roll. For the floor in a city apartment, it fits just perfectly. It is not recommended to use this material only for tiles and cardboard-based floor coverings.
It is best to mount the membrane film across the room. First, it is desirable to cut the material. Cut strips need to be rolled up. For laying, simply remove the lower protective layer from the membrane. Self-adhesive stripes on the floor should be straightened in the direction from the center to the edges. They should be laid with an overlap of about 30 cm. This will provide reliable protection.
Thus, “Technonikol” is very good for a city apartment, roll waterproofing. The price for it is low, and it has excellent quality. But you can, of course, save even more and purchase the usual ruberoid for the floor in the apartment. It is best to stick it on a concrete slab using a special composition. Bitumen in an apartment is, of course, not worth it.
Surfacing waterproofing for floors in urban dwellings is rarely used. It is worthwhile to close floors using such material only if you have the skills to work with a gas burner. Otherwise, the production of such an operation in a city apartment can become an extremely dangerous enterprise. In any case, the unpleasant odor with this method of laying will necessarily spread throughout the porch, which can cause dissatisfaction with the neighbors.
Sometimes, for waterproofing floors in urban apartments, an ordinary roofing material is also used. This material is mounted on concrete using special adhesives. When covering the floor using any of the above-described waterproofing materials, it is imperative to make allowances for the walls.
Features of work in the bathroom
Roll waterproofing for the bathroom floor is laid according to a simpler technology. After all, it is usually not necessary to dismantle in such a room. The floors in the bathrooms of urban apartments are most often originally made of concrete. Therefore, the preparatory work in this case will most likely consist only in their alignment. All cracks and chips present in the concrete coating must be covered with cement-sand mortar. You can start waterproofing the floor about two weeks after this procedure. In this case, the sticking of roll material is carried out in the same manner as in ordinary rooms. Concrete for better adhesion can first be primed with a deep penetration agent.
If it is supposed to subsequently lay the tiles in the bathroom, it is best to use rolled material based on fiberglass or fiberglass to protect the floor from moisture. Since this option of waterproofing is characterized by increased strength, it can be leveled using a solid roller.
How is the work in the basement?
The technologies for waterproofing the floor on the basement are similar to the methods for laying rolled materials in the bathroom. The only difference is that in this case several layers of material are usually used. After all, protection in the basement of the house should be as reliable as possible. Otherwise, ground moisture will penetrate the basement.
Clay is poured onto the floor in the basement first, and then a layer of sand. Next, a concrete screed is poured. Its thickness should be 8-10 cm. You can start waterproofing the floor only after the concrete has gained sufficient strength. That is, not earlier than two weeks after pouring the screed.
Waterproofing with rolled floor materials in the basement is usually done with a gas burner. Lay strips of deposited material with an overlap of 20 cm. Also, the waterproofing insulator should go 20 cm to the walls of the basement floor. The deposited material is laid in two layers. You can close the floor on the basement and the usual roofing material. But in this case, it is better to put three layers of waterproofing. The joints of the roofing material strips in the basement are sealed with a gas burner.
