Floor waterproofing is one of the most important stages of the construction of a private house. Errors in these works can lead to dampness in the house, the destruction of the walls and the foundation. Permanent dampness in the room can adversely affect not only comfort, but also on the health of his tenants. That is why the waterproofing of the floor should pay special attention. About what waterproofing is and for what it is needed, let's tell me further.

Waterproofing and floor substrate

Whatever the basement will be in the house, or not, before organizing the flooring of the floor, it is necessary to put the substrate. Moisture, as everyone knows, from the course of physics, due to the capillary movement rises up. The more denser the soil, the better the moisture will rise to the top. If the soil density is reduced, leaving an air pocket between its particles, the size of 0.5 mm and more, then moisture movement is much difficult. To do this, a layer of rubble fraction 30-50 mm is placed on the soil. If the moisture is close to the surface (shallow groundwater occurrence), then instead of rubble, you can use a brown stone. This layer will create a sufficient number of air pockets that will be an effective hydrobarier.

Basic principles of waterproofing device:

• The rubble layer should not be less than 100 mm. After laying it, it is thoroughly tamped with vibrats or hand tools. The surface of the rubble is stacked by a layer of river or career sand. Its height should be 70-100 mm. Similarly, like crushed stone, sand needs to be carefully tumped.
• If the groundwater approaches the surface too close, crushed stone can be mixed with bitumen or other waterproofing compositions. In the absence of such a problem, it is possible to replace crushed stone with a claw. This material acts as an excellent heat insulator.
• On the surface of the sand before the pouring of the draft screed can be laid a layer of waterproofing. Usually for this use runneroid or hydroize.
• If you neglect by these works and to store a rough screed on a naked soil, the moisture will penetrate into the concrete and when freezing and expanding it is easy to destroy it. So the substrate is required to clean.

Waterproofing foundation

The foundation is the basis of any structure. From the correctness of its design and fill, despite its design, the term and safety of the operation of the entire building depends. The foundation directly contacts with the walls, which is why its poor waterproofing is guaranteed to lead to the appearance of dampness on the walls.

Key conditions of the waterproofing of the foundation:

• The type of waterproofing depends on the type of foundation. Thus, bitumen rolled materials are used for ribbon bases, and penetrating materials are used for the monolithic foundation.
• The foundation must be processed completely from the base to the upper surface. This is especially true of buildings with the ground floor. Thus, waterproofing should restrain moisture, which is in the ground below the zero mark. Otherwise, the spring flooding of the basement cannot be avoided. The inner surface of the foundation isolate membrane material.
• When installing a column foundation, all pillars must be qualitatively treated with bitumen mastic, including their upper surface on which lags will be laid. The upper surface can be launched with mastic and put on her pieces of rubberoid. Wooden lags themselves are necessarily soaked with special impregnation or mastic, because the tree is first will suffer from moisture - it will just start rotting.
• To reduce the destructive influence of moisture on the walls of the building, on the surface of the ribbon foundation before the first round of the brick is laid by a layer of waterproof.

Waterproofing floor under the screed with your own hands

The waterproofing of the first floor is performed if the house does not provide the ground floor. Otherwise, it is simply not needed, since the waterproofing of the basement will be performed. When the substrate from rubble and sand is made, you can proceed to the device of the main waterproofing layer.

Basic materials and tools for waterproofing do it yourself:

• Ruberoid.
• Rubelast.
• Hydroisol.
• Polyethylene foam large thickness (200-300 microns).
• PVC membranes.
• Joinery knife, roulette, greasy tape.

Each of these materials is characterized by both price and operational characteristics. So, the cheapest polyethylene construction film is the easiest in the installation. However, it has much worse indicators of wear resistance, vapor permeability than membrane material or rubberoid. The choice in one way or another to make the owner.

The order of installation:

1. Laid web material strips overlaps with binding insulated joints. Life size should overlap at least 150 mm. In the case of laying plastic film glued joints using a wide adhesive tape construction. If you fit more manufacturable material, weld seams it is necessary in accordance with the manufacturer's recommendations.
2. Further, when laying the screed of concrete reinforcing mesh is used. So that it does not break the insulating material, it is placed under the special lining. As the latter can use the small plates of roofing material or other dense material.
3. In the case of pouring a rough screed, the reinforcing layer is not used. She is made of skinny concrete. Then another layer of waterproofing is placed on which the reinforcing belt is already installed and the pure screed is poured.
4. You can apply waterproofing a warm floor with your own hands on a rough screed and put the plates of extruded polystyrene foam. The finishing floor is already flooded. Such a "puffy" floor will be perfectly to restrain moisture and serves a long time. Waterproofing floor under the tile is done similarly.

Waterproofing floor in a wooden house with their own hands

Wooden floor requires more attention than a concrete screed. Too much floor humidity may cause rotting lags and geepboard. The complexity of the situation with wooden floors is that the problem can be defined only when it will be practically catastrophic. If marks will appear on the surface of the boarding board, then the results will be terrible on the reverse side. We'll have to transfer the entire floor, and this is "pleasure below average." That is why the waterproofing of the wooden floor should be treated very responsibly, especially if the floor is a carrier design. This type is used in frame houses that are installed on the pile foundation.

Floor waterproofing stages:

1. The foundation pillars from all sides are mandatory processed using bitumen materials. Usually, bituminous mastic or molten resin is used for these purposes. The upper part of the pillars is not only filed by bitumen, but onto its surface pieces of rubberoid in several layers are stacked.
2. Lags are mandatory are processed by antiseptics and moisture-repellent materials. The floor itself is laid out of moisture-resistant plywood, which is not exposed to moisture.
3. In order to make the protection of the floor even more reliable, the lags below are muffled with moisture-resistant plywood, then the rolled waterproofing material is stacked on top, and a layer of insulation, and on top of another layer of plywood or draft boards. This floor will be Chernov.
4. Then the draft coating is again stacked by a layer of waterproofing from membrane material and finishing floor. It can be parquet if there is no heavy load in the room, for example, in the bedroom. For waterproofing wet places in the house, a light bulk floor is used, which is perfect for the bathroom and kitchen.

Internal waterproofing bath do it yourself

The floor must be protected not only from external sources of moisture, but also from internal. Gusting the pipeline of cold or hot water, problems with heating - can cause the flooding of the room. This is especially true of the bathroom, where water leaks is constant phenomenon.

The procedure for performing work on waterproofing in this case is as follows:

1. So that the moisture does not have absorbed into the floor and did not cause its destruction, the filling tie of concrete is better to isolate with penetrating solutions. The cost of such waterproofing is not too high, and the service life and efficiency is quite good. Make work immediately after the construction of a finishing screed.
2. As soon as the solution is well frozen, its surface is cleaned with a metal brush. On the floor surface should not fall off pieces. After cleaning, the dust is cleaned with the help of an industrial vacuum cleaner.
3. Once the floor becomes clean, it should be abundantly moistened. It is done until the puddles begin to form on its surface. Excessive moisture is cleaned by the usual rag.
4. After that, after 1 hour, a waterproofing solution is applied to the surface of the floor. Do it with the help of a maclove or ordinary brush. As soon as the first layer of the solution begins to push, it is a little wetted and apply a second layer.
5. After drying the second layer, the floor is again wetted and covered with a polyethylene film. Full ripening of the waterproofing layer occurs in 21 days, after which the film can be removed.

Often, liquid polymer floors are used for waterproofing economic buildings and garages. They are made on the basis of polymeric materials or resins. Such a coating not only perfectly isolates the screed from the penetration of moisture, but also increase their service life. These floors are stacked very simple:

• First, the surface of the screed is cleaned with a brush and vacuum.
• Then its surface is impregnated with primer deep penetration for better adhesion solution with a surface.
• Then the solution based on the polymer mixture and water is prepared.
• As soon as the solution is ready, it is poured onto the surface, the spatula is cleared along the screed, and then they are powered with a needle roller. Thanks to him, air bubbles are removed from the solution. Such a coating is very good, it looks interesting and does not let down moisture.
