Hydraulic fracture for a well to protect clean well water. Technology of cracks filling

In the construction and further operation of the well, it is important to pay special attention to protecting water from pollution by ground and surface water. It is for this reason that it is important that the concrete rings have well sealed joints. This also applies to those places where the cutting of technical communications into the well is being carried out. Ensure the purity of drinking water can only be with the full integrity of the structure. If the repair work is carried out irregularly, it can lead to unpleasant consequences for human health. After all, no one knows what harmful substances and how much can come with groundwater.

The use of modern technology in sealing

Earlier, wooden pegs and patches were used to ensure the tightness of the well, as a drawback of this method is the swelling of the material from the effects of moisture. Subsequently, impurities enter the well. Today, a hydropump for a well is used, which is a modern method of repair. It is a mixture, the cost of which is quite high. For this reason, a hydraulic splint can increase the cost of building a well. But this technology is justified, as a result, foreign waters do not penetrate into the drinking water. Visiting the store, you will be able to find hydropumps in a wide range, which are represented by different manufacturers. Experts advise to trust trusted brands that have proven themselves in the market. For example, one of the best materials is "WaterPlag", which is sold as a dry mix.

For reference

Before the hydraulic splint for the well is installed, the composition must be prepared by diluting with a certain amount of water. As the main constituent mixture is cement and quartz sand, with the help of a seal, you can stop even a strong leak that goes under pressure. After application, the solution will solidify in 3 minutes, and then expand. It is very convenient that the work can be carried out at a fairly low temperature, but only if the thermometer has not fallen below + 5 °. For the 25-kilogram bucket of this mixture the consumer will have to pay 4100 rubles.

Hydrofoil of the brand "Peneplag"

If you install a hydraulic splash for the well, you can prefer the composition "Peneplag", which is realized as a dry powder and after dissolving in water it can be used. With its help, it is possible to seal brick and concrete structures. It stiffens the mixture in 40 minutes, and for the same volume that was mentioned above, you will have to pay 8200 rubles. As practice shows, this solution is one of the fastest in time setting. The remaining application requirements are similar to other hydraulic splints, for example, application should be carried out under conditions not lower than + 5 °. After sealing, the treated area should be moistened for 3 days, otherwise the seal will not get the quality of resistance to moisture and quickly cover with cracks.

Use of Hydraulic Felt of the brand "Puder Ex"

If you need a hydropump for the well, then you can choose the product "Puder Ex", which is a high-speed mixture, and after the application seizes within 7 seconds. The material is effective against leaks, filterable moisture and water under pressure. The seal can be applied for instant insulation, and you will have to pay 2500 rubles for a 15-kg bucket. If you compare with other materials, then the mixture described above is not too expensive, but high-quality. According to the manufacturer: with the help of this hydraulic seal can be sealed leak under pressure in 7 atm.

Technology of cracks filling

Waterproofing of the wells can be carried out using the technology of installing hydraulic seals. Most often this product is sold as a dry mix, which is previously diluted in warm water. It is important to adhere to the recipe, which is recommended by the manufacturer, while choosing materials that would not be harmful to human health. The use of dry mixes intended for sealing gaps in drainage drainage and sewerage structures, as well as reinforced concrete products, is unacceptable. Hydraulic splash for the wells, the reviews of which will allow you to make the right choice, can be used to seal large and small cracks that are preliminarily broken by a perforator or a jackhammer. It is recommended to expand the fracture by 2.5 and 5 cm in width and depth. From the walls of the well, it is necessary to remove loose concrete. For the recommended time until the moment of setting, an enlarged crack should be filled, and after embedding it is carried out by brushing the lump of solution into the crack. If oozing water, then the cast seal should be kept for 3 minutes. When the waterproofing of the wells is carried out according to the described technology, it is necessary to smooth the surface with a spatula after application of the material, with the help of this tool it is possible to transfer the surpluses of the composition to surfaces that have been freed from loose concrete. Deep and wide cracks should be treated with a spatula in the direction from top to bottom. Minor defects can be handled as you please.

Reviews on the method of using the hydroplugs "Waterplug" / "Peneplag"

Concrete rings can be sealed with these compounds, which are used to restore the integrity of brick, concrete and masonry walls. Such seals can cut off the pressure leak. The composition "WaterPlag" is used in non-pressure pipelines, while "Peneplag" can be used for sealing a strong leak. As the basis of the composition is aluminate cement, to which quartz sand and chemical elements are added. After compounding with water, the composition seizes in a few seconds, gradually expanding in the channel. According to the manufacturer, interaction with the concrete surface is possible at the capillary level. Waterproofing of the concrete well, according to the recommendations of consumers, should be carried out by the method of introducing the material into the groove, and the mixture should be prepared 90 seconds before the filling.

Reviews about the features of use

At one time, consumers are advised to fill not more than half the volume of the enlarged cavity, while the formed cork should be held for about 2 minutes. If you decide to use the Water Plag composition, then the penetrating waterproofing should be applied to the surface from the outside, after that the remaining volume of the cracked compound is filled with the Pinicrit composition, the upper part should be leveled with a spatula.

Preparation of hydraulic seals by one's own hands

Any hydrogeon may be prepared by any domestic master, the mixture for wells in this case can only be used when the water is technical. This is due to the fact that the inertness to the liquid is only branded compounds that do not contaminate the water in the well. In order to independently manufacture a cork, it is necessary to use fine sand and cement. Cracks should be cemented with cement. Dry fractions are mixed in a ratio of 2 to 1, with most of it will be sand. The working solution should be inserted into the crack with a spatula, and then put a sheet of roofing iron, which is supported by a beam. Waterproofing seams for this technology involves the removal of the patch in 3 days, then the concrete plug is treated with penetrating waterproofing.

The main advantages of using hydraulic seals for waterproofing the well

Despite the high cost, hydraulic seals are used more and more often, due to the many advantages of this technology over other methods of work. First, the solution is suitable for quickly eliminating and further preventing fluid leakage through the slots, as well as holes. Secondly, to prepare the mixture before use is easy enough, even a novice master will be able to cope with this. Thirdly, the hydroplane has a high resistance to the effects of gasoline, alkalis and oily substances, as well as dilute acids and salt solutions. It should be mentioned that the hydroplane is environmentally safe, frost-resistant, does not undergo corrosion and shrinkage, and is also characterized by high adhesion.
