How and what to seal up the gaps between the rings in the

To protect clean well water from possible contamination by surface groundwater, which has a number of impurities, it is necessary to seal the gap between the concrete rings, as well as the place of tie-ins to the mine utilities. Perform this procedure yourself will not be difficult. Next, we consider how and how to close up the joints in the well between the rings, as well as other cracks.

What are the reasons for the seams to leak?

At the time of repair work, the well is already a finished structure, which has some of its structural features.

Therefore, the reasons that could cause a leak in the cracks, there are quite a lot:

• Rings made by different manufacturers can be with or without locks. Accordingly, the seams of the latter are less tight.
• In the process of making the well, the builders did not seal the joints with tarred rope. This process should be monitored by the customer in the course of work, otherwise there will always be problems in the well associated with the depressurization of the joints.
• Not quite the right place for a well. When planning it is necessary to take into account the peculiarities of the hydrological and geological conditions of the area. In unstable soils, soil movements are possible, therefore the seams may diverge, especially if the well was constructed incorrectly.
• If the upper seams are above the level of soil freezing, the gaps may diverge due to demi-season freezing and thawing of the soil.

In any case, the problem can and should be solved by repair work, the quality of which will also determine the quality of water in the well.

What to do sealing

Hydraulic seal

The best option for sealing gaps is the hydraulic seal - a special material for the well. Dry mix can be purchased in special stores, after which you just need to prepare the solution with your own hands.

In order to produce a high-quality composition, in its implementation it is necessary to strictly follow the recommendations from the manufacturer, which, as a rule, are applied to the package. The amount of dry mix is ​​selected according to how active the flow is. As a rule, about 150 grams of water is taken per kilogram of hydraulic seal.

If the pressure head is large, it is necessary to change the proportion by increasing the amount of the dry mixture to seven parts. After kneading, which should last no more than 30 seconds, a solution is obtained that looks like a dry earth.

Note! The temperature of the water used for the solution should be 20 degrees Celsius.

It is impossible to knead a large amount of the composition, as the hydraulic seal quickly sets. Therefore, the putty must be prepared in parts and only after its full use, you can prepare the next batch.

A solution of cement and liquid glass

Another popular way to seal gaps is a solution of cement, liquid glass and sand. The proportion is 1: 1: 1.

This method has proven itself to be very effective and at the same time quite simple. True, after each cleaning of the well, it is necessary to process the seams of the well with such composition anew.

How to close up

As an example, consider how to seal the gaps in the well with the help of hydraulic seals. As mentioned above, the technology of using this composition is quite simple, so the work can be performed without the involvement of specialists. The only thing when working with the water seal, hands must be protected with gloves.

So, the instruction for sealing a leak is as follows:

• Before plugging a leak in a well, it is necessary to free its internal cavity from loose, delaminated concrete. To do this, you can use a jackhammer.
• Then the place of occurrence of a leak or crack should be expanded to 25 mm, it should also be deepened by 50 mm.
• Then the hydroplomb is quickly mixed in the required proportion.
• Next from the composition it is necessary to blind the hands with a lump and in sharp movements to push it into the embroidered slot. The seal must be kept in the slot for several minutes.
• After completion of the work, it is necessary to clean the tool, since after hardening the composition, this will be very difficult to do.

Tip! If the hole is located vertically and has an elongated shape, then the fitting should be done from the top down.

I must say that the price of the hydroplomb is quite high, so not all companies that are engaged in repairs of wells, use this composition. Therefore, if you decide to use the services of specialists, you should clarify this point in advance. The fact is that other materials will be less reliable and durable.

As for any guarantees or durability of such a repair, it can be very difficult to predict. To say with absolute certainty that the sealed seams will not flow again is almost impossible. Much depends on the reasons why they depressurization occurred, the quality of the well repair and some other points.

If the situation repeats with time, then in this case there is nothing left but to do the repair again.

Conclusion

Having understood what to repair the cracks in the well, this procedure will not be difficult. The most important thing is to comply with the above technology, so that in the near future you will not have to spend money on purchasing the material and perform the procedure again.

If the work is done correctly, the gaps will remain tight, at least until the next cleaning of the well or even longer. Additional information on this topic can be obtained from the video in this article.
