One of the best materials for sealing leaks in a concrete structure is considered a hydraulic seal. It eliminates leaks in 1-2 minutes and is not washed out with water in the future.
The principle of operation of the hydraulic seal
The hydraulic seal is a fast-acting repair compound. The active chemical components included in it ensure reliable elimination of leaks in the concrete structure. One of the main differences between hydraulic seals and other repair mixtures is the rapid stop of leaks with pressure.
How to choose a high-quality hydraulic seal?
First of all, we look at the adhesion index to concrete. 1.5 MPa and above is considered sufficient.
The material must be high-strength to mechanical stress. The compressive strength should be at least 40 MPa.
The composition of the hydraulic seal should not include chlorides, since at the point of contact they can cause corrosion in concrete.
It is recommended to choose a non-toxic material.
Is it possible to make a hydro seal yourself?
If the leak needs to be repaired urgently or you want to eliminate it at no cost, then you can use folk methods, such as a mixture of cement with sand and water, wooden plugs, tow, etc. Of course, such "repair work” cannot guarantee a successful result. After all, a tree in a humid environment will eventually begin to rot, which will cause bacteria and fungus to multiply, and a mixture of cement with sand and water is not a fact at all that it will seize and eliminate the leak at least temporarily.
Conclusion: improvised materials can be used to temporarily eliminate leaks, but only professional certified formulations, such as Teknoplug or Teknoplug Yildirim, will help to properly and reliably seal leaks.
Tekno hydraulic seals are high-quality proven repair mixes that are characterized by high adhesion to concrete and tolerance to contact with drinking water.
Teknoplug is kneaded in the proportion of 270 ml of water per 1 kg of dry mixture and is set within 1-2 minutes.
Teknoplug Yildirim is an instantaneous hydro seal that begins to set after 2 seconds. It is mixed in a proportion of 200 ml of water per 1 kg of dry mixture.
