Create a stream of sandstone

Properties of sandstone

Basically, sandstone is considered to be soft and not very resistant to frost and other adverse weather conditions. This assumption leads to the conclusion that because the material is constantly exposed to water and its movements, it is not suitable for the construction of a stream. But no two sandstones are alike: Depending on their specific composition, some types are very hard, frost-resistant and therefore good to use for the planned project. This is especially true for types of sandstone such as greywacke. However, you should not actually use soft and less robust sandstones, as they would weather quickly.

Seal the sandstone stream bed well

However, even hard sandstone has the property of drawing strong water - which of course in one Stream is not wanted. You can use the material to a greater or lesser extent, however waterproof do. Above all, they are suitable for this

• Pond liner / liquid pond liner: inexpensive and proven, but visually striking due to the black color
• Epoxy resin and other viscous sealants: clear, transparent, are painted or sprayed on like paint, easy to use

The said funds bring you up after you do that Sandstone bed designed and, if necessary, grouted with trass cement or another suitable mortar. Make sure to build the edge of the stream slightly elevated so that the soil and bank vegetation do not absorb water from the stream.

Alternatives to sandstone

If sandstone is too tricky for you due to its lower weather resistance, depending on the type, you can fall back on other alternatives:

• Use of hard stone, such as granite
• Model the stream from concrete (and embedded natural stones)
• Stream out stainless steel build
• natural Biotope design with the help of pond liner

Simple pond liner is the material of choice when it comes to building a natural biotope. Pond liner allows individual design options as it is very flexible. Well hidden (e.g. under potting soil and stones) it is hardly noticeable.
