4 options for sealing a concrete creek
So that the artificially created brook does not dry out in the garden after some time, you must seal its underground waterproof. This also applies to creeks made of concrete, because the material draws water and is also attacked by constant moisture. There are various possibilities.
How to watertight a concrete creek
There are numerous materials that make water courses waterproof. For a concrete watercourse, you also need agents that keep moisture out. The following four options are often used.
Pond liner / liquid foil
As practicable as inexpensive is the sealing of the concrete streambed with pond liner. If you do not want to make the effort to lay the foil carefully, you can use the liquid version. This can simply be spread or sprayed onto the dried and hardened concrete, is phenol-free and completely harmless to humans and animals - this is especially important in streams that lead to a fish pond.
epoxy resin
In contrast to the black pond liner, epoxy resin is colorless and not only seals concrete, but also streams made of wood or natural stones. The material is viscous and can therefore be easily spread.
Dichtungsschlämme
Also sealing slurries or sealing slurries, as used for the sealing of house walls and cellars, has proven to be practicable for artificial streams. This material is mixed with water, applied to the cured and dried concrete and then allowed to dry as well. Sealing slurry is available as a two-component material and can also be used to fill cracks and other damaged areas in the concrete stream bed.
sealing powder
In contrast to the other sealing materials so-called sealing powder is not applied to the already dried concrete foundation, but instead admixed with the cement mixture before construction. The use of this mortar additive thus saves you another step, but has less effect. Sealing powder only reduces the water absorption, but can not make the concrete completely waterproof.
Tips
In fact, getting concrete waterproof makes a lot of work and requires accuracy. Instead, you can simply do without the concrete and lay out the stream only with pond liner. This also allows you more flexibility, finally, concreted structures, once dried through, can be difficult to correct again.
