A sandstone wall is usually a drywall

The construction of solid sandstone buildings is not very common in the Central European climate. In order to achieve legally approved insulation values ​​and the necessary static stability, the walls must be fifty centimeters or thicker. For dry stone walls in the garden and on the property sandstone is an ideal choice.

A living stone

Sandstone belongs to the soft rocks and is therefore more associated with the "living" building materials. Its high porosity of up to 25 percent makes it both "breathable" and moisture-binding as well as conditionally stable. Therefore, sandstone is used as a material preferably in dry construction outdoors.

Rarely are buildings or load-bearing walls made of sandstone, as in the temperate zone of Central Europe required insulation values ​​can be achieved only consuming. In Mediterranean climes and warmer climates, sandstone buildings are more common.

Walls with possibility of attachment

Typical sandstone walls can be found in gardens, as property boundaries or embankment fortifications. Often, a sandstone wall is combined with jewelry or decorated stone work. When designing the garden with sandstone art, for example, outstanding gargoyles, integrated planters or well and seat attachments are popular from walls.

The large selection of sandstone species allows great freedom of design. Countless colors and textures can be selected from the different and numerous existing mining regions. In addition, there are specific physical properties of the sandstone such as the individual density, the weather resistance and the frost resistance.

Biotopes, attachment and privacy

Sandstone dry stone walls perform an important biological and botanical function when constructed with open joints and "loopholes". They form small biotopes that provide many small and microorganisms and many plant species with a safe and pleasant home.

If sandstone walls are grouted and closed, massive opaque borders are created that can be adapted to any style of construction and architecture. Manufacturers and retailers offer not only irregularly broken and split sandstones, but also a few standard block sizes. Usual are cubes with sides of twenty centimeters and cuboids with widths of forty, fifty and eighty centimeters and the ups and downs of twenty, twenty and forty centimeters.

Tips & Tricks

If you are planning a sandstone wall that will support another building such as a roof or a stone arch, a concrete foundation is recommended to support static stability and to provide an insulating layer against de-icing salt.

Weight and price

In relation to other rocks, especially in the hard stone area, the weight of sandstone is low. A cube weighing twenty centimeters in the side weighs between 15 and 18 kilograms. For one square meter of wall area, it is necessary to calculate with about 400 kilograms of sandstone, with larger depths with correspondingly more.

The high amount of sandstone around the world makes it a cheap rock. The price of sandstone depends on the frequency of occurrence and the cost of mining. In principle, special optical features such as colorations, for example in the green, red or blue range, increase the price. Expressive textures are another major factor.

The costs for a sandstone wall are in addition to the pure material price from the type of pre-processing, the transport costs and the cost of delivery together. For this purpose, impregnating agents and possibly mortar must be taken into account.
