Obmazochnoy waterproofing foundations
The contents
Waterproofing of underground structures is an extremely important task on the correct implementation of which depends on how the room will be dry. The fact that the Foundation walls, basements and concrete tanks permanently in contact with water. Naturally, over time, this leads to their destruction and cracking.
Just need to give some clarification on the ways to protect from moisture. Obmazochnoy waterproofing is only one of methods, which due to its simplicity and reliability is very popular among builders.
What is obmazochnoy waterproofing ↑
You need to recognize that each type of waterproofing can be used in certain conditions. Obmazochnoy waterproofing for Foundation is no exception.
Its structure obmazochnoy waterproofing for Foundation is a multi-layer coating, the thickness of which may vary from one millimeter to several centimeters. This parameter depends on the conditions where it is applied protection of buildings from groundwater.
If to speak about internal obmazochnoy waterproofing, it helps protect the room from the accumulation of capillary moisture. As a result, inside will be dry and comfortable at any time of the year. Even in the spring floods.
Obmazochnoy waterproofing for the Foundation can be as a cement or bitumen based. Naturally, the properties of two materials are significantly different from each other.
When concrete or steel piles are processed using obmazochnoy waterproofing, it creates a special film. It allows much more reliability to protect the Foundation from groundwater. Its main function is to arrest moisture. As a result the main construction material can not deform.
An important advantage of membrane waterproofing for Foundation is considered a reliable protection for the entire surface of the plate. Moreover, to apply this substance does not need to possess any skills. It should also be noted the low price of the substance.
How to choose a mastic ↑
Of course, it is best to buy Brushable waterproofing for the Foundation on the basis of bitumen. But that’s not all. The fact that there is a huge number of modifications of matter, each of which has its own unique qualities. Therefore, when choosing you should consider the following options:
- The temperature at which they will be working.
- The surface area you intend to cover obmazochnoy waterproofing.
- For internal or external works necessary to remedy.
- The timing of.
- What load will occur in the coating, treated with a protective agent.
- Finances that you can allocate for this type of work.
Six main parameters that you need to pay attention to when choosing obmazochnoy waterproofing the basement.
Features of use of different types of coating waterproofing for the Foundation ↑
You should start with hot bitumen. Such a material for coating waterproofing the basement is comparatively cheap and provides pretty good protection. Moreover, this technique is considered one of the oldest in the world.
Of course, for many centuries the main part was added many supplements that gave substance new properties. The result obmazochnoy waterproofing for the Foundation began to better penetrate the structure of the concrete slab, also increased the elasticity parameter.
Unfortunately, they do not work. Hot bitumen require special heating equipment at the site. It is responsible for ensuring that the sealant from the solid state to the liquid passed. Also, when using these substances is necessary to strictly follow safety measures to prevent accidents.
An important advantage of such a material for coating waterproofing of the Foundation is to work even at low temperatures. As a result, if you need a large you can make waterproofing even in the winter.
It is best to buy mastic, which is an organic solvent. In this case, for applying, you will need a brush or spatula, for the treatment of which no special skills are needed. By comparison, with the same injection waterproofing without professional technical skills and appropriate equipment to work will not work.
Bitumen mastic for waterproofing of waterproofing of the Foundation can include or not include polymers. In the second case, the substance will be much more elastic. Moreover, several times to increase the quality of bonding. Also significantly will increase the temperature range in which you can use.
Polymers in membrane waterproofing for foundations greatly expand opportunities to use substances. So you will be able to cover them, for example, the roof. But the inclusion of additional substances significantly affects the price.
So if you just want to do membrane waterproofing exclusively for the Foundation you can do without the polymers in the composition of matter. But if the scope of work is quite broad, additional supplements will allow you to choose a versatile ingredient for many types of surface.
Also you should know that the mastic solvents not recommended for use in enclosed spaces. Due to a lack of oxygen within the harmful fumes can damage your health.
To avoid this you need to use mastic, which is ordinary water. The characteristics of a substance does not differ from the analogues with solvents. But it has almost no smell and is recommended by many experts for work indoors. Important advantages means could be considered a short period of drying.
When you need to make Brushable waterproofing a large area, with time to spare, the best option would be bitumen-latex emulsion. They are also called liquid rubber. Such substances are well suited for the processing of foundations of various industrial projects.
Application ↑
The process of applying the substance on the Foundation does not represent special complexity. But in order to get protection, you need to follow this algorithm:
- Clean the surface from dust and dirt.
- Prepare the Foundation: seal crevices, round corners and eliminate sharp protrusions. The surface should be perfectly smooth.
- Apply the primer to the Foundation.
- After the primer is dry, treat the surface a quick-drying bitumen varnish.
- Prepare a paste for application.
- Apply the first layer of mastic. For this it is best to use a roller and a spatula. Strokes should be vertical.
- Make the second and third layers.
- In new buildings for the best protection you can use fiberglass. It will allow to avoid damage of the protective layer shrinkage.
- For horizontal waterproofing it is best to use mastic hot application. It needs to be heated to a temperature of 180 degrees.
When the mastic is completely dry, you will need to insulate the Foundation. In the extreme case can be limited to backfilling of soil. Thus it is necessary to use clean sand without impurities. To drain moisture from the walls of the house dig a drainage.
The results ↑
Technology application does not represent special complexity. To carry out waterproofing does not require expensive equipment and materials. Despite this kind of protection allows you to stop the destruction of the Foundation of 50-60 years.
