Waterproofing of cellars from the inside with their own hands

Usually the basements are waterproofed already during the construction phase of the building. At the same time, the protective material is laid under the floor, and also the walls of the underground room are treated from the outside. However, nothing lasts forever, and sooner or later the waterproofing layer loses its qualities. As a result, dampness appears in the basement. Of course, you can excavate it from the outside and glue the walls with one more layer of waterproofing. However, the procedure is quite an invoice. In addition, the floors can not be insulated from the outside. In this case, a slightly different method of protection against dampness is usually used - the waterproofing of the cellars from the inside. This method is not so effective, but it helps to prevent the penetration of groundwater to the ground floor of the house quite successfully.

Types of waterproofing basements

There are several ways to protect the ground floor from moisture. The simplest are:

• Bonding of surfaces with roll materials.
• Smearing them with polymer mastics.

However, for the waterproofing of the cellars from the inside, these two methods are used very rarely these days. Most often they are used to protect the basement floors from the outside. The fact that the moisture-proof film created by these technologies, keeps on the surfaces is not too hard and with time under the pressure of water begins to exfoliate. More modern methods include:

• Penetrating waterproofing.
• Application of liquid rubber
• Injection insulation.
• Application of water repellents
• Use of liquid glass.

In each of these cases, you can get a pretty good quality waterproofing of the cellar from the inside. The materials used are different. Next, let's look at the advantages and disadvantages of all these technologies.

Oak waterproofing

The protection of the basements from dampness can be carried out using roll materials. Most often, the surface is pasted with a common roofing material. More modern and expensive analogues are also used. It can be euroruberoid or glass-ruberoid. As already mentioned, this method is used to perform such an operation as the waterproofing of cellars from the inside, extremely rarely. Sometimes the ruberoid pave the floors of the basement under the screed. In this case, water penetrating from below, can not lift it and tear it away from the surface.

Lubricating waterproofing

This is the name of the method for protecting the basements from moisture penetration, in which polymeric compositions are used. Usually it is a different kind of emulsion or mastic with the addition of bitumen. They can be applied to the surface both cold and hot. For the waterproofing of cellars from the inside, these tools are practically not used. Bituminous mastics are also commonly used to protect the basement floors from the water outside.

Penetrating waterproofing of the cellar from the inside

This method consists in applying special mixes to the moistened walls of the basement. By contacting with water, they form crystals filling all surface irregularities and penetrating into it by 15-25 cm. The merits of this method include first of all the full protection of walls and floor from moisture. In fact, this is just an ideal way of waterproofing the premises from the inside, since with the water pressure from the outside in this case nothing will peel off or swell. The disadvantages of a penetrating variety include that it can be applied only to concrete that has a sufficiently large number of pores.

Injection protection of basements

The merits of this method can be attributed primarily to reliability and efficiency. Injection waterproofing of the cellar from the inside is made with a special syringe (packer). In this case, methylacrylate, epoxy and polyurethane compounds are used. This method is also very suitable for internal waterproofing of basements. Disadvantages of it are the complexity of the performance and high cost. However, the pluses can be attributed to the fact that injection waterproofing can be used locally, that is, only where there is actually a leak.

Use of liquid glass

This is one of the most popular ways to protect the basement floors. Waterproofing the cellar from the inside with liquid glass - the method is relatively inexpensive and at the same time very effective. This product is sold in cans and used in a mixture with a concrete solution. The minus of this method is considered to be some difficulty in the performance. The fact is that after adding the liquid glass to the concrete, the latter loses its plasticity and grasps literally in a few minutes. Therefore, the kneading has to be done in very small quantities.

Liquid rubber

With the use of modern mastics can also be made reliable waterproofing of the cellar from the inside. Materials on bitumen base with latex additives (liquid rubber) create an elastic and very strong moisture-proof film on the walls and floor of the basement floor. This is the only type of lubricant, recommended for use from the inside. Liquid rubber is usually sold in barrels of 200 liters. Latex film of 2 mm provides the same protection as 4 layers of roofing material. The disadvantages of this variety can be attributed only to high cost.

Self-contained waterproofing of cellars from the inside with the use of liquid glass

A mixture for protecting the basement floor in this way can be prepared by hand. The basis for it is cement brand not lower than M300. It is mixed with well sifted sand. Concrete is made in proportion one to two. First mix dry cement and sand. Then add water and water glass. The volume ratio of the latter with cement is 10 * 1. Water is added so much that the solution is sufficiently liquid for convenient application to the surface. Mix it in small portions.

Before proceeding to processing, all surfaces must be cleaned of dirt, degrease and dust. The solution is applied in the same way as a conventional plaster in 3 layers. When using this tool, it is worth bearing in mind that liquid glass is chemically quite aggressive. Therefore, work should be done with gloves. In the event that the composition falls into your hands, they should be rinsed with a weak solution of vinegar.

A distinctive feature of cement mixtures with the addition of liquid glass is that, when resistant to moisture, they do not transfer contact with air very well. Therefore, at the final stage it is advisable to go through one more layer - this time with ordinary plaster.

How to waterproof a cellar with liquid rubber

Next, consider another popular way to protect the socle floors from moisture. Waterproofing the cellars from the inside with their own hands using liquid rubber is performed in several stages. First of all, it is necessary to arrange good ventilation of the room. As in the first case, the walls and the floor are first cleaned of dirt, various kinds of stains, paint residues or plaster. Also, all surfaces must be dust-free. This can be done using a conventional vacuum cleaner.

Further, the surface of the walls and floor is primed with a special agent, usually coming with a liquid rubber. Then they themselves apply bitumen-latex mastic itself. Grease can be carried out by any convenient tool - brush, spatula, roller. When doing this work, you need to carefully monitor the fact that all gaps, corners and joints are filled with rubber. Pasta is best filled in portions in a bucket and mixed with a drill with a special nozzle. After application, the layer should dry well. In the event that the work is done qualitatively, the product forms a continuous, sealed rubber "bag" in the room.

However, at this event, such as the waterproofing of cellars from the inside, it can not be considered finished. The liquid rubber will not pass water even at high pressure. However, under its layer over time, concrete itself may start to break down. As a result of its shedding, water will fall directly under the rubber film, with the formation of bubbles on the latter. To prevent this from happening, the rubber layer on the walls should be additionally plastered or bricked, that is, simply press it firmly against the surface of the concrete.

Injection waterproofing

Although this method is considered one of the most effective, it is used for self-protection of basements against moisture quite rarely. It's all about the complexity of the work and the need to use special equipment. The cheapest of all injectable materials is a polyurethane polymer.

Of course, it is unlikely that someone will make such a complex treatment with their own hands, but we will briefly consider how to make a waterproofing of the cellar from the inside with injections. This operation is performed as follows:

• In the wall holes are drilled 2 cm deep at a distance of half a meter from each other.
• Further in them, with the help of special equipment, the injection compound is injected.
• Then, various measures are taken to protect the surfaces from mold.
• At the final stage, the walls are additionally plastered.

Penetrating waterproofing by yourself

In this case, also carefully prepared surfaces of walls and floor. In addition, they will need to be watered with water. Penetrating waterproofing of the cellars from the inside with their own hands is carried out either on wet, or on freshly poured concrete surfaces. The cracks in the walls should be opened and cleaned from dust. Then they need to be sealed with a selected type of penetrating waterproofing. The composition should be kneaded thicker. In a couple of days he will swell and tightly cork all the cracks.

In the next step, a penetrating mixture is prepared, in fact, for treating the surfaces themselves. Which one should I choose for carrying out such an operation, as the basement waterproofing from the inside? Penetron is one of the best and most commonly used formulations. On the surface of the floor and walls it is applied with a very thin layer (0.02 cm). To achieve this, make a fairly liquid mixture. After drying the first layer, the product is applied to the walls and the floor again.

Bonding of the floor of the basement with roll materials

The waterproofing of the garage cellar from the inside, in the same way as the protection from the moisture of the cellar, should be carried out in stages. Begin work usually with floor processing. Only after drying the selected product can begin to waterproof the walls. Semi, because it is subjected to the most severe stresses in terms of the impact of groundwater, in any case, should pay the most attention. Let's get acquainted with the technology of its waterproofing in more detail.

For the treatment of the walls of the basement from inside the roofing material is not used. First, it lags behind the surface as a result of water pressure from the outside. And secondly, when it is used in the future, it will be problematic to perform a finishing operation. However, the waterproofing of the basement floor from the inside with the use of a roofing felt can be quite a successful decision.

In order to ensure that such protection against moisture is of high quality, the excavation is first done to a depth of about 20 cm. Next, the crushed stone and sand are packed into the resulting foundation pit with a careful tamping of each layer. Above is covered with ruberoid with an overlap on the walls to a height of 20 cm. Then the material is smeared with bituminous mastic. Then another layer of roofing material is spread. At the final stage, the basement floor is poured with a cement screed with a thickness of at least 5 cm.

As you can see, using modern materials to make the basement waterproofing is not too difficult. The most important thing is that when performing work, you must observe the laid-down technologies. In this case, the protection of the basement from moisture will be reliable and durable.
