Stone wall on a slope - what you have to look out for


Plots are not always perfectly flat. Why you must always intercept slopes and embankments, which types of stone wall are suitable, and what you need to pay attention to when building, you will learn in detail in this post.

Intercept slope and embankment

Slopes and embankments on the property must always be intercepted by a corresponding retaining wall. If there were no wall below the slope, it would be washed away over time or even start to move.

For the correct interception of a slope, there are three points that are very important and must be observed

1. the right planning of the wall
2. the stability of the wall, which must always be appropriate to the slope or embankment
3. the drainage from the slope to the foot of the wall (drainage)

If smaller retaining walls (below 120 cm in height) are sufficient for the embankment, you may also be able to plan your own - possibly with technical assistance. For walls that need to be higher and staggered retaining wall constructions planning by a specialist is absolutely necessary. Here also a so-called stability certificate must be created.

In these cases you can also hire a GaLa farmer with the planning. The execution by a specialist is also advisable in these cases, since errors in the construction can endanger the stability of the wall.

Gravity walls

In general, it is advisable to use retaining wall structures on the slope as a rule on heavyweight walls. This applies even more, the longer or steeper the slope slope is.

Heavyweight walls are characterized by having a particularly wide foot (usually at least one third of the wall height). This makes the wall particularly stable. She may then rejuvenate towards the top but again.

For stability, the foundation and its structure are crucial. It must be absolutely in the frostreien range (at least 80 cm deep, possibly deeper) and be sufficiently sustainable. Concrete quality and the quality of concrete also play an important role here.

Tips & Tricks

Especially the topic of water drainage is always crucial for retaining walls. A drainage system must be properly planned, dimensioned and executed. Mistakes in this area or failure to comply with the prevailing water situation can have serious (and expensive) consequences.
