Waterproofing work is carried out for different designs and surfaces of any structure. They allow you to get rid of numerous problems that arise in the process of exposure to water elements. Most often, the need to use high -quality materials arises when arranging a basement and foundation. However, the cement screed is often formed on the floor, which also needs optimal waterproofing.
The main nuances of waterproofing floor screed
This work can be:
antifiltration;
Anti -corrosion.
A specific variety is selected depending on the purpose and features of the floor screed itself. Additionally, it takes into account what financial resources can be allocated for these purposes.
The screed can perform the following functions:
moisture protection;
prevention of condensation on different surfaces;
protection against corrosion;
Lack of ability to quickly destroy concrete.
Varieties of waterproofing work with screed
This action can be performed in different ways, depending on the choice of waterproofing, which happens:
Crystaline. This waterproofing usually involves the use of oxidized bitumen, which is mixed in the production process with organic substances and other additives. As a result of the use of different mixtures, the formation of good floor protection from moisture is ensured. In this case, all solutions are well connected to the concrete base. Additionally, usually in the process, a special reinforcing fiber is used, which positively affects the strength and stability of the coating before different mechanical influences. The likelihood is reduced that during the operation of the floor will appear on concrete cracks.
Bloody waterproofing. It involves the use of materials presented in the form of rolls. Some varieties are reinforced, while others are simple and inexpensive. It is best to choose modern varieties of waterproofing materials, which are durable and durable, and they are initially equipped with a special wrong layer in the creation process, which, when heated by a construction hairdryer, burner or other thermal equipment, begins to melt. For gluing, it is enough to attach the material to the desired sections of the floor, after which it is good and firmly connected to it. The formation of joints is not allowed, so laying is laid out.
Injection waterproofing. It involves the use of such solutions, which, when applied, enter the structure of concrete itself, improving its stability before the influence of moisture. Such a coating does not need to be updated, however, if chips or cracks appear on the surface, they will no longer be protected from moisture.
Sprayed waterproofing. Applied by a special spray, which forms an even and optimal waterproofing layer on the entire floor.
Combined waterproofing. Involves the use of several of the above varieties at once, which will actually obtain high -quality protection of the screed from moisture.
There are also several modern methods of work, but the above options are considered the most popular and often applied.
Preparatory stages before creating waterproofing
Before using direct waterproofing materials, a certain training should be carried out, which is the following stages:
The existing flooring is completely eliminated from the floor surface, regardless of what materials it is made of;
high -quality purification of the base is made, for which different pollution, dust or spots and other problems are completely eliminated from it;
The floor is checked for the presence of various cracks, recesses and other defects that are eliminated in any case, and in the presence of minor problems they are eliminated by a small amount of construction composition, however, if there are significant irregularities and other defects of the coating, then a new cement screed of optimal thickness is often formed;
The entire surface is treated with high -quality primer, which allows you to eliminate the smallest problems, and also improves concrete adhesion with used waterproofing materials.
Technology for applying gluttoen and coating waterproofing
These varieties of waterproofing work are considered the most popular, affordable and easy to organize. Therefore, they are performed very often, and there are no particular difficulties if the preparation of the screed itself was correctly carried out.
Bloody waterproofing. It involves the use of roller materials that are overlapped on the surface, and the formation of several layers is considered optimal atimal. Cheap polyethylene or roofing material can be used, but they are considered short -lived and not too reliable. The optimal choice is the use of special polymeric materials that are based on mastic or bitumen. The lower layer is heated using a gas burner, after which the molten material is attached to the base, which guarantees optimal, durable and reliable gluing.
Crystal waterproofing. Most often, a special varnish is used here, which are based on different polymers or bitumen. Materials are applied with rollers or brushes, as well as other standard tools. The resulting waterproofing is highly efficient and reliable, however, even when using high -quality materials, the service life of the resulting coating usually does not exceed 5 years.
Waterproofing of floor screed is an important process that is implemented by different technologies and materials. It is important to choose the option that will be inexpensive and easy to create.
