Embankment stones - Important tips for buying

In the case of embankment stones, the first thought is involuntary of a planted embankment secured with staggered stones. Although this is the main area of ​​use of embankment stones, there are other interesting uses on the property. Embankment stones are not only hollow hollow stones inside, but can also be solid.

Embankment stones are among the most versatile design elements in gardening and landscaping.

Materials that make up embankment stones

Here are very diverse, different materials used - different types of stone, clay mixtures but also classic concrete, which is mainly used for planting stones and hollow bricks. Depending on the material used, the properties and the stability of the individual stones are also quite different, as well as their weight.

Possible uses in the garden

Embankment stones can also be used for erecting so-called dry stone walls, garden walls or bedding borders, or for securing and greening natural or artificial slopes in the garden. Here, however, always some static conditions are taken into account.

Slope stabilizers with embankment stones can only be carried out statically safely under certain conditions and must be sufficiently and professionally secured.

This is the only way to safely exclude slipping of the slope and thus of the stones. On the other hand, there are fewer pitfalls in the construction of dry stone walls, although the statics can not be completely ignored.

Dry stone walls with embankment stones

Dry stone walls can be constructed with various types of embankment stones, including plant stones. If it is not natural stone, embankment stones are often equipped with a tongue-and-groove connection, which allows a mortar-free building of walls. With different capstones, which are usually glued as well as the cornerstones, then either closed walls can be built, or - by using plant stones with differently shaped projections - also green walls.

Types of embankment stones

  • Stone blocks
  • Bricks of different materials, with and without tongue and groove connection
  • decorative stones
  • soldier blocks
  • Trapezium stones, mostly executed as plant stones
  • Multisteine, also mostly executed as planting stones

Especially with trapezoidal stones then can also perform curved walls, without the need for special angles. This enormously increases the variety of design options.

Step by step: slope protection and embankment design

One of the main purposes of embankment stones is slope protection and - in some cases - embankment planting. The risk that the slope could slip is here quite larger than is generally assumed, therefore, the current building instructions for such slope protection must be met as closely as possible to ensure the static safety.

For safety reasons, embankment protection may only be carried out for embankments with a maximum height of 2.50 meters!

In some cases, a building permit is required for this, but this varies depending on local conditions and applicable building regulations in each state. However, to seek the advice of a professional is in no way wrong.

The basic structure of an embankment protection consists of the following elements:

  • A foundation (is required)
  • optionally also a filter layer below the foundation
  • a leveling layer
  • the embankment stones whose offset must be calculated according to the angle of inclination and the height of the attachment
  • a backfill and, if necessary, a filling in the embankment stones for greater stability as well as
  • a drainage

1. Create the foundation

In the run-up to the hillside fortifications, some excavation work is necessary. Up to a height of 1.50 meters, as a rule, a foundation of gravel and gravel is sufficient; above this, it is essential to cast a concrete foundation with concrete grade B15, ie light-weight lean concrete.

Underneath a filter layer is to be applied, which consists of at least 20 cm of compacted gravel and gravel. The gravel and gravel material used in construction must be frost-free, frost-proof and, above all, permeable!

2. The drainage

The drainage must be laid in such a way that it collects the draining or infiltrating water before it reaches the wall and drains it sufficiently, otherwise it could endanger the stability of seepage water that no longer drains off.

3. Fixing the stones

The first stone row must always stand on a layer of leveling mortar, but a thickness of 2 - 3 cm are usually sufficient here. The offset of the stones to the rear must be at least 15 cm, but depending on the inclination angle of the slope and the height of the overall construction, the offset changes accordingly to ensure sufficient statics.

4. The backfill

Above all, care should be taken when securing the slope that a sufficiently strong backfill layer of gravel and gravel is to be installed behind the individual rows of stones. The stones themselves - in the case of plant stones - must also be filled with crushed stone.

Only on top can then come a layer of humus to allow for planting. The position of the stones must always be carefully checked with a spirit level, string and solder.

Embankment fortifications "by eye" are very dangerous!

The Alpinum

The Alpinum was a special feature of the embankment fortification - here only natural stones are used, between which usually wild herbs or mountain flowers are planted, which together with the rustic natural stones in unhewn form a very charming, alpine picture that fits very well with rustic houses. Because of the statics of the slope, such an alpinum must be planned very carefully as possible by a specialist, also the planting and selection of suitable plants requires expertise. With a good layout, an Alpinum usually requires little care.
