During the construction and further operation of the well, it is important to pay special attention to the protection of water from pollution by ground and surface waters. It is for this reason that it is important that concrete rings have well-sealed joints. This also applies to those places where the penetration into the well shaft of technical communications. It will be possible to guarantee the purity of drinking water only with complete tightness of the structure. If repairs are not carried out regularly, this can cause unpleasant consequences for human health. After all, no one knows what harmful substances and to what extent can come along with groundwater.
The use of modern technology in sealing
To guarantee the tightness of the well, wooden pegs and tow were previously used, as the drawback of this method is the swelling of the material from moisture. Subsequently, sewage gets into the well. Today, a hydraulic seal is used for a well, which is a modern method of repairing. It is a mixture, the cost of which is quite high. For this reason, a water seal can increase the cost of building a well. But this technology is justified, as a result, extraneous pollution does not penetrate into drinking water. Having visited the store, you can find a wide range of water seals that are represented by different manufacturers. Experts advise trusting trusted brands that have established themselves in the market. For example, one of the best materials is Waterplag, which is sold as a dry mix.
For reference
Before a water seal is installed for a well, the composition must be prepared by diluting with a certain amount of water. The main component of the mixture is cement and quartz sand, with the help of a seal you can stop even a strong leak, which goes under pressure. After application, the solution will harden in 3 minutes, and then expand. It is very convenient that the work can be carried out at a rather low temperature, but only if the thermometer has not dropped below + 5 °. For a 25-pound bucket of this mixture, the consumer will have to pay 4100 rubles.
Hydro seal of the Peneplag brand
If you install a water seal for a well, you can prefer the Peneplag composition, which is sold as a dry powder and can be used after dissolving in water. It can be used to seal brick and concrete structures. The mixture freezes in 40 minutes, and for the same amount that was mentioned above, you will have to pay 8,200 rubles. As practice shows, this solution is one of the fastest setting time. The remaining application requirements are similar to other water seals, for example, application should be carried out under conditions not lower than + 5 °. After sealing, the treated area must be moistened for 3 days, otherwise the seal will not gain the quality of resistance to moisture and will quickly become cracked.
The use of water seals brand "Puder Ex"
If you need a water seal for a well, then you can choose Puder Ex products, which are a quick-acting mixture, and after application they set in 7 seconds. The material is effective against leakage, filtered moisture and water under pressure. A seal can be applied for instant isolation, and you will have to pay 2500 rubles for a 15-pound bucket. If we compare with other materials, the mixture described above is not too expensive, but of high quality. According to the manufacturer: using this hydraulic seal, you can seal a leak at a pressure of 7 atm.
Gap sealing technology
Waterproofing of wells can be carried out according to the technology of installing water seals. Most often, these products are sold in the form of a dry mixture, which is previously diluted in warm water. It is important to adhere to the recipe recommended by the manufacturer, while choosing materials that would not be harmful to human health. The use of dry mixtures intended for sealing gaps in drainage drainage and sewer structures, as well as reinforced concrete products, is unacceptable. A hydraulic seal for wells, reviews of which will allow you to make the right choice, can be used to close up large and small cracks that are previously embroidered with a puncher or jackhammer. It is recommended to widen the crack by 2.5 and 5 cm in width and depth. Loose concrete must be removed from the walls of the well. For the recommended time before the moment of setting, an expanded crack should be filled, and after sealing it is carried out with a wrist throw of a lump of solution into the crack. If water oozes, then the thrown seal should be retained for 3 minutes. When the wells are waterproofed according to the described technology, it is necessary to smooth the surface with a spatula after applying the material, using this tool you can transfer the excess composition to surfaces free of loose concrete. Deep and wide cracks should be treated with a spatula in the direction from top to bottom. Minor defects can be processed as you like.
Reviews on the method of using the water seal "Waterplag" / "Peneplag"
Concrete rings can be sealed with these compounds, which are used to restore the integrity of brick, concrete and masonry walls. Such seals are able to cut off a pressure leak. The composition “Waterplag” is used in pressure-free pipelines, while “Peneplag” can be used to seal a strong leak. The basis of the composition is aluminate cement, to which quartz sand and chemical elements are added. After combining with water, the composition sets in a few seconds, gradually expanding in the channel. According to the manufacturer, interaction with the concrete surface is possible at the capillary level. The waterproofing of the concrete well, according to the recommendations of consumers, should be carried out by introducing the material into the groove, and the mixture should be prepared 90 seconds before filling.
Usage Reviews
At one time, consumers are advised to fill no more than half the volume of the expanded cavity, while the formed plug must be held in your hands for about 2 minutes. If you decide to use the Waterplag compound, then penetrating waterproofing should be applied to the surface from the outside, after that the remaining volume of the embroidered crack is filled with the Pinicrite compound, the upper part should be leveled with a spatula.
Do-it-yourself water-filling
A water seal can be independently prepared by any home master, the mixture for wells in this case can only be operated when the water is technical. This is due to the fact that only branded compounds that do not pollute the water in the well have inertness to the liquid. In order to make the cork yourself, you need to use fine sand and cement. Cracks should be closed with cement. Dry fractions are mixed in a ratio of 2 to 1, with most of the sand. The working solution should be introduced into the crack with a spatula, and then laid with a sheet of roofing iron, which is supported by a beam. The waterproofing of the seams using this technology provides for the dismantling of the patch in 3 days, then the concrete plug is treated with penetrating waterproofing.
The main advantages of using hydraulic seals for waterproofing a well
Despite the high cost, water seals are used more and more often recently, due to the many advantages of this technology over other methods of work. Firstly, the solution is suitable for quick elimination and further prevention of fluid leaks through slots, as well as openings. Secondly, preparing the mixture before use is quite simple, even a novice master will be able to handle it. Thirdly, a water seal has high resistance to gasoline, alkalis and oil substances, as well as diluted acids and saline solutions. It is impossible not to mention the moment that the water seal is environmentally safe, frost-resistant, not subject to corrosion and shrinkage, and is also characterized by increased adhesive ability.
