What is the waterproofing and the basic requirements for it
Water has the ability to penetrate virtually all building materials and to destroy them. Components solutions lose their connection, wood swells and rots. freezing and thawing cycles also play a role. Ice breaks the most durable concrete. That is why it is so important to protect structures from atmospheric moisture and dirt. Waterproofing material - it webs and compositions to prevent penetration of moisture.
Waterproofing materials must meet several basic requirements:
- not to skip or absorb water;
- do not form a condensate;
- have high strength and elasticity;
- be resistant to high and low temperatures;
- not afraid of direct sunlight and other natural influences.
Virtually all modern waterproofing products meet these requirements, we can only correctly pick them according to the specific design.
Types and properties of modern waterproofing materials
Builders are classified waterproofing on several grounds. At the point of use protection can be external or internal. External hosted on roof and on the outside of the building, internal, Respectively, on the inner surfaces of walls and partitions.
Another grading - for a specific purpose. Distinguish protivonapornuyu insulation and pressureless. Protivonapornaya used to cover roofProtection wall and foundation from groundwater. Gravity, for example, protects basement inside the building.
Waterproofing may be different in composition: bitumen, polymer, Degtev, rubber and minerals.
The types of waterproofing materials differ in their mounting technology. They are divided into affixed (membrane and linens) penetrating and obmazochnye, injectable.
It is difficult to say what type of waterproofing better than others. Let's look at the different technologies for their application, in most cases, this is a decisive factor in the selection.
Roll roofing waterproofing material and advantages of its application
For the manufacture of rolled materials take basis - fiberglass or non-woven polyester - and it is applied to natural or polymer bitumen. Top fabric for waterproofing sprinkled with fine sand, and the bottom adhesive layer protecting film.
Such a coating can be used for roofing or as a topcoat.
Advantages and disadvantages of waterproofing in rolls:
| pros | Minuses |
| Application for insulation of all types of materials, from wood to metal | For stacking require perfectly flat, dry surface |
| Economy - such products are relatively inexpensive | The joints are sealed by fusing - the skills needed in such work |
| Resistance to abrasion | It may not be laid at a temperature below 10 degrees Celsius |
| Not resistant to mechanical damage | |
| In most cases, applied in several layers |
The properties of bitumen-polymer waterproofing
Bitumen-polymer waterproofing enjoys almost more popular than the roll. She is represented by various mastics and slurry is applied in several layers. It is used for protection foundation building, flat roofs and fill poolsAs well as the closing of cracks in the walls.
| pros | Minuses |
| It can be applied with a thin layer | It loses its elasticity at temperatures below zero |
| Different economical consumption, no scraps | It serves not more than 5 years |
| Ideal seals folds, cracks and other difficult places | Melting requires the installation |
| Waterproofing may be used for the walls | It requires careful preparation of the base |
Obmazochnaya polymer waterproofing: excellent tightness
Waterproofing materials based on polymers, in principle, different from the bitumen composition only. They further include latex, polyurethane, acrylic and other polymeric components. Unlike the bituminous composition, the polymer has a high elasticity and a wide temperature operating range.
Features penetrating material for waterproofing
To isolate the cracks and holes in the concrete special use composition of cement and silica sand.
| pros | Minuses |
| Prolongs the service life of concrete structures | Suitable for insulation of concrete structures of cement grade not lower than the M150 |
| Perfectly resists corrosion | Not used for waterproofing masonry |
| It allows the treated surface to "breathe" | It is applied at temperatures below 5 degrees Celsius |
| It does not emit toxic substances | |
| Not sensitive to mechanical damage |
The attractive liquid waterproofing materials
The liquid applied waterproofing spraying and forms a coating without seams and creases.
| pros | Minuses |
| Protection against noise | It is not recommended to operate the protected coatings at temperatures below zero |
| It forms a wear surface resistant to chemical and mechanical action | It applies only in dry calm weather |
| It can be painted in any color | It needs special equipment to apply |
Geotextiles for waterproofing
Bentonite mat - a two-layer clothBetween the layers of which the layer of bentonite clay.
| pros | Minuses |
| Resistance to mechanical stress | High price |
| Wide temperature range of operation | Installation is carried out in dry weather |
| Withstand multiple freeze-thaw |
Modern waterproofing materials such as injection
The principle of this type of sealing assembly lies in the process of injecting the hydrophobic gel between the ground and the details of construction.
| pros | Minuses |
| A significant reduction in terms of jobs | Very quickly it hardens, because of what you need to work very quickly |
| Cost savings for repairs | |
| Even high quality coating as necessary local repair |
Membrane moisture protection
At the height of the development is now a new technology - the use of membrane materials.
| pros | Minuses |
| Easy installation | High price |
| Not afraid of sharp temperature changes | |
| It does not require special care | |
| It can be used for waterproofing of geometrically complex structures |
Production of waterproofing materials: who should be trusted?
For your own peace of mind and confidence in the quality of the material, use the products of famous brands. The high quality of this waterproofing guaranteed long-term experience of application and numerous examinations. Editorial HouseChief.ru pick you up for some producers, has earned high praise from professionals in the building:
- surface waterproofing - products Ksaypeks, Penetron and Lahti has shown excellent results for the protection of reinforced concrete structures.
Waterproofing Isomat Aquamat - is indispensable for the protection of swimming pools, wells and septic tanks Surface waterproofing Ksaypeks - bituminous waterproofing - leaders in this area are recognized Technonikol and the second most popular, but not in quality, can be called flashing, IzoArt, Grid and Descartes.
Bituminous waterproofing waterproofing - roll waterproofing - the most demanded products is Technonikol, Technoelast Izol, rubiteks and Bikrost.
Roll waterproofing Technoelast - waterproofing membrane - there is no competition from domestic companies Technonikol.
Membrane waterproofing Technonikol

What is the waterproofing is better and why?
As already mentioned, in each case, to make a choice. If to generalize, for the internal waterproofing is preferred to use liquid rubber. It reliably seal the space basement and other premises.
To work on the waterproofing of external surfaces are considered to be the most reliable membrane coating and bentonite mats.
If you have experience in the waterproofing, share it in the comments to this material, it will be very interesting to our readers!
