During the construction work, it is necessary to take care that the foundation of the building has a certain level of strength and waterproofing. All this is capable of preventing the problem arising in the future and prolongs the service life of the construction.

For a long time during waterproofing activities, specialists use mastic providing thermal and chemical resistance, as well as excellent sustainability of the foundation to moisture. The mastic is quite simple in applying and is an indispensable building material in the construction of foundations, thereby avoiding breaks in the process of its shrinkage.

As is known, a number of adverse factors always affect the foundation of the house, starting from temperature fluctuations and ending with groundwater, which leads to its global damage. It is for this reason that the choice of waterproofing material needs to be approached especially carefully, giving preference to one that is able to resist with all external and internal changes as much as possible.

Mastic composition

Mastic is made of:

• binding organic matter;
• filler;
• Diluent.

Fillers provide an increase in heat resistance and reduce fragility at low temperatures. As they use mineral short-fledged cotton wool, quartz, asbestos dust, ash, talc, dolomite, cement and limestone.

Mastic diluent may contain organic solvents, fuel oil, tar, bitumen, petroleum oil and water.

Mastic is used to glue waterproofing and roofing materials, as well as to arrange mastic and vapor insulation, isolation of steel underground pipelines and other systems in order to ensure their protection against corrosion.

Waterproofing foundation

Advantages of waterproofing mastic for foundation:

• resistant to chemical aggressive environments;
• withstands the temperature difference from -70 to +1200 s;
• After drying, it turns into a membrane that allows you to withstand huge loads;
• The resulting membrane has high mechanical strength and elasticity;
• Mastic application technology is absolutely safe;
• Activities for its application can be carried out in any season;
• Differs the simplicity of installation;
• It is not required to have special qualifications to work with it;
• During its applying to the foundation, you can not use additional equipment.

Types of waterproofing foundation:

• horizontal (it is superimposed across the walls, as well as in the joints of the foundation and basement or at the junction of the base and walls of the lower floor);
• Vertical (applied to the vertical area, promotes protection against weather and from the penetration of soil moisture).

Mastic for foundation

Types of mastic:

1. Cold
2. Hot

Hot mastic applies only after preheating. It happens:

• Gudrickampolimeric (heated to 70 ° C);
• Degtess (up to 130-150 ° C);
• Revinobitume (up to 170-180 ° C);
• Bituminous (up to 160-180 ° C).

Today there is a huge number of different brands of mastic, for example, targeting MDK-G-60, MDK-M-50, etc. - Such designations indicate the temperature of its melting. For the production of mastic, various binders fillers and dry components are used, which provide a decrease in its fragility at low temperatures, an increase in heat resistance and a reduction in material consumption. Fibrous fillers are particularly popular, which are treated wood and asbestos to flour.

Bituminous mastic for waterproofing foundation

Bituminous waterproofing of the foundation is an oldest method of protecting underground structures from the harmful effects of moisture. The seamless protective layer of this building material allows you to screen wooden, concrete, reinforced concrete and other structures. Mastic for waterproofing the foundation, the price of which is quite affordable - the optimal choice for the base isolation with their own hands.

How to choose a mastic for the foundation

Depending on the composition of bituminous waterproofing, allocate:

• bitumen-polymeric mastic;
• Ordinary bitumen mastics.

A separate class is a polymeric look. However, small foundations are recommended to be treated with coating waterproofing on the basis of an ordinary bitumen. When this material is selected, try to give preference to large manufacturers, study in detail the information on the package, since different companies have the same product characteristics to differ significantly in terms of cost.

The advantages of bitumen mastic for waterproofing foundation:

• This mastic for the foundation has an acceptable price and convenient during transportation;
• resistant to the effects of aggressive media;
• It can be operated with different air temperatures;
• practical and durable;
• You can work quickly with it;
• You can do without utility workers;
• has good adhesion to different surfaces;
• With it, you can create a waterproof seamless screen;
• does not swell under the action of moisture;
• does not crack;
• protects the surface from mold and fungus;
• Withstand temperature changes.

Disadvantages:

• labor-intensity of activities for large areas of the foundation;
• Sometimes you need to wait until the waterproofing layer is polymerized and typed properties.

Stages of work

To create an excellent waterproof layer, it is recommended to use mastic bitumen, bitumen emulsions or mastic on organic solvents. Bituminous mastic must be heated to 160-180 C. It is better to apply it on the surface that is not subjected to strong mechanical effects. The composition on organic solvents should process the outer side of the foundation, and the emulsions are the surface inside the basement.

Technology:

1. Initially, it is necessary to calculate the surface area of \u200b\u200bthe foundation.
2. Next, we are determined with the consumption of material by 1 square. m.
3. Then the surface is aligned, cleaned from small pebbles and dust.
4. If the foundation has pores, it is recommended to impregnate them with a primer that improves the adhesion of the waterproofing layer to the mineral base.

In order to apply mastic, you can use a different tool that allows you to evenly distribute the composition. The material is applied in two layers, while there should be a pause between the finishing coating, the value of which depends on its parameters.

Scope of mastic

Waterproofing bitumen mastic for foundation is a single-component substance, on the basis of sealant and bitumen. The sealant forms a flexible and hard protective layer. Bituminous mastic can create wonderful adhesion to asphalt, brickwork, concrete and many other building materials. Can use for applying to a vertical surface.

Bitumen-based mastic is great for filling and sealing cracks on the roof, in the foundation and basements. It is also used as a substrate for felt and waterproofing membranes, between the foundation and brick masonry, seals around the water supply pipes.

Bituminous single-component mastic is used as:

• seamless monolithic and deep isolation of various surfaces that are in contact with underground waters;
• protection of metal and concrete surfaces;
• protection against adhesive base and dust under other materials.

As a result, a monolithic membrane is formed, without joints and seams.

Leading mastic manufacturers

Some consumers believe that mastic produced in Russia is inferior to the analogues of import companies. However, despite the fact that local mastic is much cheaper - it does not mean that it has a lower quality. At the same time, among domestic brands it is easier to find the one that can be used in our climate conditions.

So, for example, reliable mastic, which will be ready for temperature changes, is the mastic "Blam-20", manufactured by AOZT Ryazan Cardboard Rubberoid Plant.

It is also worth paying attention to the mastic of the plant for the insulation of AST them. Shevarkkova. It is made by him, taking into account all the technologies and on the new equipment.

Today popularity is gaining the mastic of the domestic brand of superflex, which is made by Maxit Group. Superflex is a ready-to-consume material forming a special film after drying. It is distinguished by excellent elasticity and ease of work.

A decent place has won the tack mastic that meets the basic requirements for similar materials. Especially remarkable is that it has the ability to colize in the necessary colors.
