How to insulate a well of concrete rings for the winter: technology, methods, materials and feedback

The question of how to insulate the well from concrete rings, excites mainly summer residents, owners of private houses and village residents. Most often this issue is solved even before the construction of the well, taking into account the climatic conditions. But this does not always happen. It happens that the insulation was not thought of initially. And faced with the problem and freezing of water in the well in the winter, its owner is fully aware of his mistake. Thus, the answer to the question of the warming of the well can be divided into two specific guidelines. The first will tell you how to insulate the well from concrete rings immediately in time of construction. The second is about what can be done after the fact.

Why did not anyone previously warm the wells?

The use of modern materials greatly facilitates the construction process. This is speed, and durability, and economic feasibility. But the "grandfather" methods proven by centuries have the right to exist. Earlier wells in Russia were built mainly from wood of special breeds. Excellent characteristics of such a well allowed to use it for many years, and low thermal conductivity of the wood did not allow the water to freeze even in the most severe frosts. But now such technologies are a thing of the past, and most often for construction use ready-made concrete wheels. By the method of digging, they are gradually immersed in the earth, reaching the required depth. To ensure that the water inside the well does not become ice, its level should not reach the freezing level of the soil in winter. If this condition is met, then problems are extremely rare. But no one is protected from force majeure and natural disasters. In any case, it will not hurt to be safe in advance, because it does not require much extra effort, and the funds spent for insulation are not so great as to risk.

What happens if you do not create a heat insulation layer?

Ignoring warming can not only bring inconvenience in the form of a lack of drinking water for a while. If a pumping station is installed in the well, and water pipes from the house go to the house, freezing of water will lead to the failure of all equipment. Its repair is a very expensive procedure, in addition, the matter is complicated by the fact that the ground in the winter freezes thoroughly, and if the water in the pipes also freezes, this can cause them to burst. Restorative work will have to be done in difficult conditions or generally postponed until the spring. Expansion of the liquid during freezing is also a cause of destruction of the concrete rings and joints between them. In spring, during floods, abundant drainage of groundwater, their pressure on the walls of the well is greatly enhanced. And any gaps will lead to the inevitable seepage of dirty water with various impurities into the well. To avoid such a problem, you must immediately know how to insulate the well from concrete rings and do all the work correctly.

At what depth should I lay a heater?

When the work is done in the course of construction, the insulation must be laid around the well gradually, as it is instilled. The depth of the insulation depends on the climate in the region. It happens that even very deep craters freeze, the depth of which exceeds 15-20 meters. Most often it will be enough to lay the insulation to a depth of no more than one and a half to two meters. The technology of this process is simple, the main thing is to follow the instructions on how to insulate the well. Ways of warming the well in many ways depend on what kind of winter in the region.

External insulation

If the frost is not very strong, the earth does not freeze deep and for long, then you can protect the crin from above by installing a wooden frame with a tight-fitting lid above it. Such a house can not just be put on the ground around the well. For him it is necessary to equip the foundation. To avoid skewing and subsidence, the foundation must be arranged according to all rules, to a sufficient depth (no less than the average freezing level of the earth) with a width of one meter. Before the concrete solution is poured, a pillow is created at the bottom of the layers of sand, gravel and soil, which will act as a drainage system. Pillow must be carefully tampered and then pour the solution. After installing the wooden frame into the gap formed between it and the walls of the well, a heater should be laid. For this purpose it is possible to use minnow, sheets of styrofoam, expanded clay or foam isole. This method is well responded to by residents of the southern regions, those who live north, the results are unhappy.

Technology of warming the well

How to insulate a well from concrete rings under the ground is a slightly more complicated question. Such work is carried out in several stages.

• The rings of the well must first be treated with special means to prevent penetration of groundwater inside. But in choosing it is important to take into account the environmental friendliness and the possibility of using the means in working with wells.
• The next layer is directly a layer of insulation. Than to warm a well of concrete rings, we will consider a little further.
• The insulation must be wrapped in a hydro- and vapor barrier layer. Most often, a film is used for this purpose. Such a measure will help avoid contact of the insulation with the ground, condensation on it.
• To fix the whole structure around the rings set a wooden formwork, it keeps all the layers together.
• Finally, the trench needs to be covered with earth. For this process, experts advise not to use the soil from the trench itself. It will be correct to alternate layers of two materials with different calibers. It can be sand and gravel or clay with expanded clay. Layers with a fine fraction are usually laid up to a thickness of 15 cm and others - 20 cm. Such a measure will help create a quality drainage system, this will reduce the risk of water contamination in the well and reduce the pressure on its walls.

This is a classic, time-tested method, and reviews about it are the most positive.

What if the crinica is already built?

How to insulate a well of concrete rings for the winter, if it is already built? The technology itself is the same as in the previous case, but the trench will have to be dug out. Such work should be done manually with a shovel. The use of specialized equipment can lead to displacement of soil and rings, disruption of the integrity of soil layers. The rest of the work is done according to the given technology. Separately it is worth noting that it is very important to worry about a good lid for the well. Heat loss due to its absence or poor adherence to the edges will also cause freezing of water. When a wooden frame or other structure is installed above the well, its lid is made in the form of a multilayered panel, in the middle of which a layer of foam or mineral wool is laid. Unformed outside the well is closed with a concrete hatch and a plastic plug. Those who live in areas with warm winters characterize this method as quite cheap and practical.

What types of insulation are usually used?

To learn how to properly insulate a well of concrete rings, you need to know what it can do. There are quite a few options. Among the newest - insulation foam. The application of such material to the walls of the well excludes seams, penoizol completely covers the entire space, eliminates the leakage of cold air or water. This technology implies the use of special equipment, it will not be possible to do it manually. And the cost of the service is not cheap, so it is not yet very common in our country. In warm regions, sometimes use mineral wool on foil. The advantage of this option is the ability to tighten the insulation around the well as tightly as possible. But some experts caution that this material is easily crumbled and may eventually break up into separate fibers and enter the water well.

Warming with expanded polystyrene

Warming the well of concrete rings with expanded polystyrene is the most successful option, experts say. The properties of this material are truly unique. It is an excellent barrier for cold air, besides it is very durable and inexpensive. For these purposes, the sheet material is most often used, which is not always convenient, because it is problematic to circumvent the rounded shapes of the rings.

Manufacturers have found a way out of the situation and offer consumers already finished insulation parts that have a semi-circular shape. Dimensions produce standard, under the most common diameters of well rings. In addition, it is possible to use bulk granular expanded polystyrene. In this case, to create a frame, you need to use wooden racks to attach a layer of roofing material to the ground around the walls of the crinica and fill it with granules. In this way it is possible to insulate the well not only with foam balls, but also with other loose heaters.

This is an effective method, and the owners of the wells, who chose it, confirm the reliability of this insulation.
