One of the stages of construction of the Foundation, is to provide good waterproofing. After all, the Foundation, as the Foundation of the building, has close, continuous contact with the ground. Rain, snow, groundwater has a negative impact on the Foundation of the house, destroying and eroding it. Especially dangerous situation is becoming in the bitter cold: water penetrating into the pores and fissures of the Foundation freezes, thereby expanding and accelerating the destructive process.
The solution to the problem will be the high-quality waterproofing the basement. Carefully read the sequence of work, simply to make the waterproofing of the Foundation with his own hands.
Technology Foundation waterproofing ↑
In order for the work was carried out efficiently in advance to determine the sequence of processes and to comply with certain requirements:
- determine the groundwater level;
- calculate the force of blistering soil;
- determine the composition of the soil;
- define the conditions of living in the house.
At the maximum groundwater level one meter below the base of the Foundation, enough to carry out vertical and horizontal waterproofing.
When groundwater level is above one meter from the base of the Foundation and quality protection against moisture provided by a wider range of activities. Horizontal waterproofing is made in two layers, which coat with a mastic. Vertical waterproofing to be carried out by a method of coating and gluing of rolled insulating materials. Depending on the size of the budget of waterproofing works, the Foundation can be further treated with penetrating waterproofing, which will provide reliable protection against the penetration of water into the smallest pores and capillaries.
When the level of groundwater, which are located above the base of the Foundation necessary to provide for the laying quality of the drainage system around the house. Also, this event is held, if the area where the house is built, is subject to very frequent and severe precipitation.
The cost of waterproofing works depends on the following factors:
- the area that requires waterproofing;
- view of insulating materials and their quantity.
The easiest way insulation provides for the purchase of bitumen. The complex process of waterproofing the basement includes the purchase of coating, roller, and a penetrating insulation materials. Also have to spend on installation of drainage system and construction of retainer wall.
The horizontal waterproofing of Foundation ↑
For waterproofing of strip Foundation with his own hands the work is done in two places:
- At 20 cm from the base of the basement.
- In the joints of the Foundation of the house with walls.
Before you start activities for the construction of the Foundation with his own hands, the bottom of the pit harboring fat clay, the layer thickness of which is about 25 cm It carefully leveled and tamped. On top of poured concrete screed layer not less than 6 inches is necessary in order to properly carry out the waterproofing of the Foundation. Concrete should be given time to dry and settle. Depending on weather conditions, this period may take up to two weeks.
After complete drying of concrete Foundation thoroughly lubricated with mastic of bitumen, on which is placed the first layer of roofing material. On top is placed another layer of concrete (thickness up to 8 cm). It needs to be carefully aligned, if necessary, lay a layer of rebar and give a well dry.
Once completed the construction works on erection of the Foundation of the belt type, it is necessary to carry out the waterproofing. For this, the surface of the Foundation covered with cement and after making the roll roofing material or other insulating material. The whole process is performed twice. The excess roll of the insulating material needs to be cut. They’re taking them down, and then pressed against the vertical waterproofing.
Vertical waterproofing the basement ↑
To accomplish this method uses a combination of a variety of materials for waterproofing of the Foundation with his own hands. Of all the combinations you can choose one and you can apply several at once. It all depends on the construction design.
Bitumen basement waterproofing ↑
For many years, this type of waterproofing is the most cheap and affordable for the consumer. The basis of the technological process is the use of a bituminous resin. Often it can be purchased in bars.
The whole process includes several stages:
- In a large pot or Chan poured used oil (a third volume) and bitumen resin in the remaining part.
- Capacity warm up. You can use the gas oven or to dissolve under the pan a fire.
- At a time when the bitumen is melted to a liquid state, it can be applied on prepared surface. The Foundation should have a flat wall to be clean from dirt and debris. The bituminous mixture is applied with a roller or stiff brush. Thus the solution better penetrates in the notches, small cracks and holes. Fluff finish approximately at 20 cm above the soil surface. Asphalt is applied in two layers, each of which must be a minimum thickness of 4 cm.
As practice shows, the bitumen impregnation allows you to create a good protection from moisture. Service life of such coverage – for about five years. After this deadline, it starts to crack and crumble.
Modern bitumen mixes contain polymer particles that help extend the life of waterproofing. Also, the market of modern materials can offer a more dense bituminous mixes in structure. They are applied with a trowel or special spray.
Okleechnoy waterproofing ↑
The use of rolled or gluing type can both separately and in the form of an extra layer of protection from moisture.
The most popular and relatively inexpensive roll waterproofing material roofing felt.
Technological process of roll waterproofing the Foundation of the house with his own hands consists of the following steps:
- In order to firmly fix on the surface of the Foundation, a qualitative treatment of the walls and Foundation of the mastic paste.
- Pieces of roofing material are heated and tightly to vertical surfaces overlap. This method is also called overlaying.
- Roofing felt can be attached on the surface by means of special mastic pastes which are greased with the surface.
Also, in addition to the roofing material known several types of waterproofing roll. These include: TekhnoNikol’, stekloizol, rubiteks, Technoelast. They are based on a special polymeric material is polyester, which greatly increases the elasticity of the waterproofing, its resistance to external negative events and improves the characteristics of the operation. Such materials are more expensive roofing material, but their cost is more than compensated high quality waterproofing.
It should be noted that this type of roll materials is the best option for self-waterproof Foundation or sauna.
Waterproofing liquid rubber ↑
This method of waterproofing is characterized by high levels of bonding, long service life and absolute incombustibility. It is also worth noting that the surface has no seams as it is observed in the case of using roll materials. It provides the best quality protection from moisture.
For those who wish to undertake waterproofing your own hands, in this case it is better to choose a one-component liquid rubber stamps «Sastopas». Its consumption rate is very economical, only 3 kg at 1 m?. The material is applied layers, the amount of which shall be not less than two. To dry the treated surface should be at least a day with an average air temperature +20°C.
Buy liquid rubber of this brand is possible in buckets of 20 kg. It is very convenient, because if the material is not completely used, tight enough to close the lid of the container, and a liquid rubber remains usable until the next use.
To liquid rubber is easy on the surface smoothly and there was good coupling, Foundation walls, you must first prepare. This procedure provides high-quality cleaning and application of primer. Liquid rubber applied with roller or trowel, following the manufacturer’s instructions.
Conclusion ↑
To carry out the waterproofing of the house with his own hands not everyone can. In order that the work was done efficiently, requires not only the availability of tools and physical strength. Definitely need to understand the features of each of the types of waterproofing, to know the nuances and sequence of works.
So the Foundation lasts a long time is not only important to carry out waterproofing works, but also to equip the drainage system. It significantly accelerates the removal of water, which in turn keeps the surface of the base from premature destruction.
