We are talking about the types of waterproofing materials and the rules of their use to protect the foundations of different types.
Water, even if it is a bit, destroys construction structures. Therefore, the arrangement of reliable moisture protection is necessary at all stages of construction. This is especially true when erecting the foundation. If it is not protected from moisture, literally immediately the liquid will begin its destructive action. Such a house will not last for a long time, and it will be uncomfortable to live in it. In order not to encounter such problems, we'll figure it out how to properly make the foundation waterproofing.

Why waterproofing is needed
Moisture getting into the foundation design is extremely undesirable. Concrete structure is such that even a small unprotected area absorbs fluid. She moves into the capillars deep into the foundation, fills it, rises above. Begin to mock the walls, the dampness penetrates the house. This is not the worst. Moisture in concrete pores in winter turns into ice. In the process of freezing, it increases in volume, which destroys the structure. Ottay and freezing cycles turn concrete into the crumb.
Located inside the reinforced concrete part of the reinforcement under the influence of water begins to corrode. Rust increases the volume of each rod three or four times. There is an internal voltage that destroys the foundation design. In addition, corrosion of concrete occurs under the action of water. Salt and acid contained in it are aggressive, they slowly destroy the material.
Therefore, it is necessary to equip reliable protection to completely prevent water from entering. There are two types of moisture protection.
Property protection
- Horizontal. It is stacked between all the structural levels to prevent fluid from entering them. Performed for all types of foundation systems.
- Vertical. Protects vertical surfaces from moisture. Performed using different materials. It is often used for columnar and ribbon varieties.
Both types of insulation are often used. It usually happens at the construction stage. When repaired, only the vertical, horizontal, in this case, cannot be performed. In addition, it is equipped with a breakfast, which does not make moisture to get to the foundation.
Varieties of materials for waterproofing
For moisture protection, different types of materials are applied. They determine the technology of work.Occake
Roll insulation on a binder from bitumen. The base is made of glass cholester, polyester or cardboard. Distinguish the glued and applied option. In the first case, the cloth passes on a bitumen paste. In the second there is an adhesive layer, which, when heated, is melted and glued to the canvas.
Inexpensive, but outdated rolled insulation, it is Ruberoid, Pergan, Tol. Modern polymer canvases used without restrictions, it is glassizole, bikrost, linocur, etc.
Refractory
Various single and two-component mastic. We are applied with a roller or brush, create a seamless coating based on any form. Initially, pasta was made on the basis of pure bitumen. Other formulations appeared later: polymer-bitumen resins, rubber-bitumen mastics and polymer resins. Their operational characteristics are much better than bituminous analogs. But the price is much higher, which is considered a disadvantage.
Pastes from bitumen are used to protect the system from deeply located groundwater. In other cases, it is better to choose modern mastics like "Profimast", "Farbitex", "Aquamast".
Penetrating
Seals the capillaries of the foundation than the water prevents from entering them. Applies only for materials with a capillary structure. It works well on concrete, it is useless for brick or stone.
Penetrating ability depends on the type of composition. The average depth of their penetration is 20-25 cm. There are mixtures that plunder for 80-90 cm. They are considered the best. Recommended at the construction stage, but can be applied during repairs. Then you have to carefully prepare the basis. The most sought-after mixtures: Penetron, Penetron, "Hydrochit", "ocked".
Injection
The method is recommended for repair work, since it allows not to conduct large-scale primer work on the release of the structure. Injectors are introduced into the base, mixtures of insulators are supplied. These are gel-acrylates, various resins and foams containing cement preparations, compositions of polymers, rubber.
Works are rarely performed independently because a certain skill is required. Preparations for injection are selected based on the state of the structure. It may be "scrape", "Epodge", "Manopoks", "PentElast".
Sprayed
The second name "Liquid Rubber". It is superimposed on the basis of cold spraying. It has good adhesion to almost all materials, so the preparation is not required. Forms a durable and durable rubber "carpet", which reliably protects the base.
Seamless coating, stacked on the surface of any shape. Installation is carried out quickly, but special devices are required. Therefore, for the waterproofing of the foundation, it is rarely applied with their own hands. Specialist services are required.
Sometimes plastering isolation is used for moisture protection. These are cement-containing mixtures that are placed by the foundation system. Specialists do not recommend using such materials. They are short-lived, they will serve no more than five years.
How to put waterproofing on the foundation
Support systems of all types are waterproof. It protects them from underground and surface waters. Before the bookmark, it will necessarily find out the depth of ground sources, the level of their lifting during the flood period. If it is higher than the foundation of the foundation system, it is necessary to equip drainage for efficient drainage. Thus, the amount of moisture decreases and the hydrostatic pressure on the structural elements is partially removed. For the discharge of precipitation is equipped with a scene.According to the rules, the foundation is insulated, as well as the floor and walls of basements, basement. It is placed in a solid layer of moisture protection around the perimeter of the construction. Even small gaps should not be. In areas where hydrostatic pressure is high, two or three layers of moisture protection of different types are mounted. It gives a good result. We will understand how to put waterproofing on the foundation of different types.
For ribbon foundations
The ribbon design is a closed loop from a reinforced concrete, which builds the construction. May be monolithic or national team. In the second case, between the base plates and blocks forming the basement walls, the reinforced thickened seam is performed. Here it is impossible to use bitumen formulations, otherwise items can shift. The very first inter-block seam, located under the basement level, is insulated with rolled cloves.
The foundation of the foundation on the joint of the supports with walls is covered with a roll-type insulation. This is necessary because the moisture content of the elements is different. Destruction will begin without protection. The waterproofing of the horizontal type is performed by any hortal blades. During construction, the entire underground part of the ribbon structure is processed outside. Thus, the carriers and interior premises are simultaneously protected. Used calene, coating mixtures or liquid rubber.
In the process of repair, all procedures are made from the inside. Then use isolation of an injection or penetrating type. The monolithic ribbon is isolated in the same way. Vertical protection is performed, the edge of the foundation system is closed. In any case, the celestum is additionally performed.
For columnar and pile structures
On the piles or the columns put on the woods or stacked the plates that become the basis for the construction. Roll insulation is applied to the poles, if they are from concrete, before their fill. Metal piles before installation are coated with two layers of insulating mixture. After installation, one more layer apply to the visible part of the part. In addition, waterproof the edge of the foundation structure with a rolled web at the level of the contact of the walls and the woodwok. Horizontal insulation is applied on the stove, usually inlet type.
Proper isolation of the foundation facility is very important. Without it, the process of the destruction of building materials will begin very quickly. It will require expensive and labor-intensive repair, because it is very uncomfortable to live in a house with constantly waving walls and floors. Therefore, it is better to immediately do everything in accordance with the construction standards.
