Quite often, where there is an increased level of groundwater, water in the well freezes. At best, ice plug is formed on the surface up to 50 cm. If the water mirror is located deeply, then the water freezes rarely, because the temperature inside is slightly higher than zero.

Consequences of the freezing of the well

• an electric power cable and water pipes can occur
• freezing and formation of ice traffic jams in the pipeline
• shift rings
• gap seam between rings

As a result, water supply is contacted and an emergency is created - the soil in the well falls and the soil falls on the surface around it.

Wells that need insulation

Wooden species of the well can not be inspired. This design is remarkably keeping the temperature. The only thing - may need a lid for warming the well. It is made of wood and mounted inward. The cover performs the protective function not only when the temperature drops, but also limits the ingress of precipitation and other items.

As for concrete structures, they have excellent thermal conductivity, so it is impaired on the same depth as the soil. Despite the fact that they will go cheaper and will be more durable to warm them.

Recommendations that will help avoid a well freezing:

• after operation, it is cleaned and treated with a disinfectant (chlorine)
• next, it is necessary to pump water, cover the well with a lid, cover it with a polyethylene film and fall asleep with leaves
• water pipes should be laid slightly below the level of soil freezing. If the surface pump is used, it must be mounted in a heated room or in the caisson jam near the well
• well well to equip a wooden frame. In order to insulate it, you can use a polystyrene or clay. They are filled with emptiness between the rings of the structure and wooden strapping

Warming of wells for the winter

Today, several methods of thermal insulation are used:

Polystyrene foam for warming well

Due to the increased structural stability, polystyrene under pressure of the soil does not change geometric sizes. It is resistant to bacteria, mold and fungus.

Mechanical and thermal indicators of polystyrene do not change 25 years. The only minus of the warming of wells by foam is instability to ultraviolet. Therefore, its surface should be protected by oil paint, tale or foil.

Well insulation procedure with their own hands:

• initially, the trench of 1.5 diameter should be pulled out
• then the shell of polystyrene on the diameter of the well is selected
• fastening takes place with the help of Schip-Paz
• next trench instillat

From above, the well is covered with a warming lid. When cleansing and repairing the "shell" is removed and installed back.

Warming of wells penoplelexomes

Penoplex or extruded polystyrene foam for warming wells has excellent thermal insulation and high strength, as well as moisture resistance and durability. It is a sterefight, does not mold, does not rot and does not absorb moisture.

Insulation isolon

The insulation of the plumbing well is the isolon is a rather simple method, since this material on one side is covered with foil, and on the other there has a self-adhesive layer.

Insulation polyurethane foam

Before heating the well in the country with the help of polyurethane foam, it is necessary to get acquainted with its main characteristics. Its application should occur at a street temperature from 20-30 degrees, otherwise the mixture is worse than foaming. Polyurethane foam is not subject to rotting, does not secrete toxic substances and does not absorb water.

The process of insulation consists of the following steps:

• initially, the well is drunk around the perimeter to the depth of the soil freezing.
• next, the components of polyurethane foam, which are located in different tanks are heated and by means of high pressure enter the spray cell (mix)
• after that, all the walls are covered with such a solution.

Due to the fact that the polyurethane foam foams and increases in volume, it is able to fill the smallest gaps and cracks. After its frost, a monolithic and rigid heat-insulating coating 2-3 cm in thickness is formed.

Polyurethane foam is afraid of ultraviolet, so it should be protected from the effects of sunlight. For this, the surface is covered with a tone, foil or oil paint.

Truck insulation

Some for convenience are carried out from the well pipeline. Accordingly, the water will tighten the pump that is installed in it. An important point is the insulation of the pipe from the well using the foamed composition, but many use the heating cable.

White insulation cover

After you were properly insulated well, you need to use the lid sealing:

1. You can use the "sandwich" variant, which consists of several layers: 1 and 3 - moisture-resistant plywood, 2 - polyurethane foam or polystyrene foam.
2. A more durable look - the cover made from reinforced concrete and equipped with a plastic hatch. Installation of such a lid occurs inside the well at the ground level, between the first and the upper rings.

It will be necessary to take care of the sealing of seams between the rings and the lid, applying the composition of liquid glass and cement.

Thus, if you were properly insulated well, the temperature in winter in it will not be lowered less than +5 degrees. Accordingly, you can easily use it. If there is no water pipe in the well and water is recruited using a bucket, you need to take care that it does not fall on the surface. Otherwise, the well may find out what makes it difficult.
