Build a natural stone wall on a slope

A natural stone wall is ideal for developing and supporting optically attractive sloping and rising terrain. The range extends from rectangular cut natural stones to layers of loose boulders. With clever use, a wall can do without aids such as mortar.

Mostly designed as a drywall

In the majority of natural stones are used to create a drywall. In addition to the attractive appearance offers plants and small animals as biotope important habitat. When making your own natural stone wall in the garden, integration is usually favored even on embankment fortifications and on slopes.

With regard to building physics, the special selection of natural stones and the construction of the layers in dry construction can often avoid or at least simplify more complex types of foundations of the construction industry such as foundations. On the other hand, classic mortar walls with cut and standardized natural stones sometimes have to be provided with elaborate foundations and drainage systems.

Construction and properties

With every wall or wall that is built yourself, the stability is also and especially in case of rainfall and strong wind, the crucial safety factor. The larger and heavier the individual stones are, the more inherent stability arises "automatically".

The construction of a natural stone wall on a drywall slope must be followed by the following steps:

1. The bearing surface serves as a foundation and is compacted well. Sagging or rinsing with rainwater must be ruled out.
2. Demarcation walls with a one-sided load by soil as on embankments need an inclination between ten and 15 percent. The overall slope is created by smaller keystones between the main bricks.
3. After every second stacking layer at the latest, a so-called binder stone must be placed continuously from the front of the wall to or slightly protruding into the ground.
4. Between the soil and the back wall of the wall a vertical layer of gravel is necessary as a drainage layer. A gravel layer between the foundation and the lower stone level must have a direct connection to the gravel layer at the lower corner. A pipe or channel discharges larger amounts of water without causing under-rinsing.
5. There must be no direct connections between the front wall of the wall and the ground behind the wall due to the interstices between the stone. This compound would favor rinses.

Tips & Tricks
