Melting water entering the well after a snowy winter can be a big problem for site owners. Verkhovodka, that is, the surface layer of water, can make it impossible to use the well. Our tips site will tell you how you can protect a well from melt water.
Why is melt water in a well so dangerous and undesirable? Yes, on the one hand, they raise the well water level, which is not always a bad thing. But the vodka is able to bring various debris, mud, chemicals, including fertilizers in the soil, into the well. And the water becomes cloudy, undrinkable. Therefore, the ingress of melt water into the well is highly undesirable..
The first thing you can do to protect your well is to choose the right place for it. The portal wrote how to build a well with your own hands. Finding water is important, but if there is a choice, then the source of drinking water is best located on a small hill. If the well is located in a low place, in the spring, in any case, there will be puddles around it, water will accumulate. This will break the waterproofing, and the top water will definitely fall into the well barrel, spoiling the drinking water.
It is also very important to take care of reliable waterproofing of the well. It can be external — it is arranged during the construction process — and internal — it can be done at any time, for example, after a gap has appeared in the well. The use of modern reinforced concrete rings, which have a lock connection, and are not simply installed on top of each other, reduces the risk of leaks and melt water entering the trunk. However, this risk still remains, because there are seams.
Roll materials are used for external waterproofing of the well. For example, roofing material, familiar to homeowners, and other special films. During the construction of the well, they are wrapped in several layers of all reinforced concrete rings. You can also use special waterproofing coatings. This can be done later, if it is possible to excavate a well..
A continuous concrete jacket around the rings is sometimes used as external waterproofing. But this is a costly method, in addition, concrete can collapse over time and swell due to soil movement.
Important! Some experts advise to equip a so-called clay castle around the well. Just tamp the clay around, which will become a natural waterproofing. But often this is not enough to protect against overhead water.
For internal waterproofing of wells, special polymer-based compounds are used. They do not affect the quality of drinking water, do not crack and serve for a long time even in harsh conditions of high humidity and temperature changes.
Impregnations and compositions for internal waterproofing of a wellbore are:
- Free-flow. They are used when there is no active leak, water simply seeps out;
- Pressure. These are seals that literally save the situation when melt water is whipped into the well. Such compositions freeze after a few minutes even in water, reliably closing a break or crack..
Important! Melted water always seeps through the top rings of the well. When the snow begins to melt, they need to be carefully examined. Dry? Everything is in order, no additional measures are needed. Moisture, condensation, small streams of water from the joints are visible? It is urgent to take action and deal with internal waterproofing.
The best effect is obtained by using both external and internal waterproofing of the well. Inside, the barrel can be completely impregnated with special compounds, having previously cleaned the walls with an iron brush. Such impregnations are sold dry and diluted with water. They need to be applied with a roller or with a brush in at least two layers, and preferably four.
Important! If melt water has managed to penetrate into the well, you cannot use such water for drinking. Disinfection, cleaning of the well will be required, it is advisable to hand over the water for analysis to the sanitary and epidemiological station.
