How is the waterproofing of the well for drinking water and

The word "well", many owners of private households understand two options - the construction of drinking water and sewage. At the same time, everyone wants that after the expiration of the time, the liquid from the source does not resemble the sewage in taste and smell, and the sewage tank can be pumped out not very often. Will help in this case, waterproofing the well from the outside and inside in different ways.

Two of these desires are affected by one problem, which is directly related to the waterproofing of the well. In the sewage system, seepage of drains into underground water horizons will be excluded, and, thus, will not allow groundwater to periodically fill the tank, which is especially noticeable during the flood and rainy season.

It should be understood that if the well rings are not waterproofed, the liquid in it will become not just dirty, but dangerous to your health.

What you need to know about waterproofing works in wells

A rather problematic construction from the point of view of sanitation and hygiene is a septic tank..

Pay attention to how waterproofing of wells should be carried out according to SNiP:

• if the volume of sewage exceeds 1 m³, waterproofing wells of this type should provide them with maximum tightness;
• when the volume of the container is smaller, it is possible to build septic tanks with the release of dirty wastewater into the soil through the filter bottom. Although, if among them are remnants of SMS or other "chemistry", only hermetic constructions are allowed on the site.

Experts advise that when there is a source of drinking water in your territory, septic tanks with a filtering bottom should not even be considered. You must understand that you and your household will live here for a long time, and therefore drinking water is needed exclusively clean and high quality. Therefore, a thorough waterproofing of wells for wells with drinking water is carried out, removing from them even the slightest possibility of contamination of the source with household drains.

Tip: when calculating the volume of a septic tank of concrete rings, take into account the number of people permanently residing in a country house.

Waterproofing for sewer wells

When buying a finished plastic or fiberglass well, you can not worry about its tightness, as it is guaranteed by the manufacturer. But in suburban areas, reinforced concrete rings are most often used for arranging septic tanks, which are laid at the desired depth.

The SNiP instruction requires that the bottom of the structure should also be made of concrete, and the inner surface of the structure, and not just the annular joints, should be covered with an airtight composition.

Among them should be highlighted:

1. Dry waterproofing mixture.
2. Compositions in which epoxy resins are added.
3. Liquid two-component sealants.

Any of them has proven its waterproof ability and has its own characteristics. For example, epoxy compounds readily resist aggressive chemicals similar in composition to gasoline, chemicals, etc.

The penetrating waterproofing of a concrete well consists of a penetrating waterproofing compound and a suture.

Independent execution of a septic tank waterproofing

It does not matter who carries out the waterproofing of sewage wells - by you or by professionals, it is necessary to prepare the inner surface at the first stage. Take the brush on the metal, clean it walls and the bottom of the well with your own hands to remove traces of the solution, dust and other components. (See also the article Bottom filter for a well: device features.)

This will allow the waterproofing compound to penetrate deeper into the material by filling in various voids.

1. Waterproofing rings well begins with joints and seams. Moisten them in advance, then the composition will have an additional strength, then apply it with a brush, and make sure that the label “for the joints” is on the packaging of the material.
2. The waterproofing of the sewer well continues by sealing the walls and bottom. Try to moisten the surface of the well rings as much as the concrete can absorb, and then coat it with a layer of waterproofing solution.
3. Apply the next layer only after the first firmly “grabs”. Do not forget to moisten the entire surface again.

1. Apply such a number of layers, which must comply with the manufacturer's instructions, written on the package of waterproofing mixture.
2. Be aware that curing takes about 72 hours. Therefore, during this period, do not allow mechanical impact on the septic tank walls and protect it from sub-zero temperatures.
3. Keep the surface wet when curing, so you can eliminate the cracking of the waterproofing. Moisturize best spray.
4. When it is not possible to wet the walls and the bottom from the inside several times during the day, cover them with a film, reducing evaporation.

How to conduct hydroprotection of a drinking source

Cement with PVA and ready mixes

Prepare a thick mixture, which is used for waterproofing water wells, carry out as follows - pour gradually into the cement PVA glue, with simultaneous stirring. There is no proportion here, the main thing is that you need to achieve such a consistency of the mortar, when it will be well taken with a spatula.

After that, with ready-made compound, seal the seams between the reinforced concrete rings. To increase the penetration of waterproofing, make the first layer liquid and apply it with a brush, trying to drive it deeper into the seams. Apply the next thick layer after the first one is completely dry.

If the price does not frighten, purchase a ready-made waterproofing mixture. Apply it to the seam with a spatula, moistening the surface of the joints beforehand.

Geotextiles

This method assumes that in the first stage you will have to close the seams with geotextiles as tightly as possible. Top seam must be insulated with liquid glass. Other flaws of concrete rings should also be covered, including cracks and pits, which can cause gradual seepage of water into the material. (See also DIY do-it-yourself well.)

Waterproofing lock

This option, unlike the others, is designed to protect the outside of the well from the water pipe. During installation of the rings around the perimeter, they make a trench about two meters high and half a meter wide, which is filled with specially prepared clay.

On the surface it is necessary to lay out with a slope from the source so that the rainwater can flow as far as possible from the pipes. In this case, the three upper reinforced concrete rings will become an obstacle for groundwater located nearby, and a layer of clay on the surface will protect the walls from the penetration of precipitation.

To enhance the external insulation, you can wrap the walls with several layers of polyethylene film. Secure the material with a glue gun or waterproof tape.

History tour

When in the old days there were no high-quality materials, they made sealing of well joints with hemp ropes of large diameter. They slaughtered the seams, and insulated the top with cement mortar.

This option can be used in our days, however, not for wells with drinking water. This is due to the fact that hemp, constantly being in a humid environment, begins to rot, and becomes a source of infection, thereby deteriorating the quality of water. Hemp waterproofing is advisable for wells that have a different purpose.

Tip: do not use liquid bitumen-containing mastics for waterproofing, as they will worsen the taste of the liquid.

When problems with waterproofing became visible during the operation of the well, then there are two options - you became their culprit when you did the work, or you were caught by not very skilled craftsmen. Therefore, try to contact companies that have already proven themselves in this field so that you do not have to face emergency repairs.

Tip: to restore damaged waterproofing, use a universal way - the insertion of a plastic liner.

Conclusion

From the article we learned how to make a waterproofing well for drinking water and sewage, which is an important step in their construction. Otherwise, you will have to constantly pump out water from the septic tank, and the water in the drinking source will spoil accordingly.
