Walls to support: you must pay attention

An important and fundamental wisdom in GaLa construction is that slopes and embankments must be "intercepted" - that is, supported. You can also use walls for this purpose. But what has to be considered, and how the support has to be planned and done correctly, you can read in this article.

Attach embankments

If there is a slope or embankment on the property, you must fasten it accordingly. In many cases, embankments are also caused by the need to sprinkle or pile up individual areas in the property in order to maintain a flat surface.

Basically, when fixing an embankment, the steeper and the longer the embankment, the more the wall has to be set up to intercept the embankment.

Suitable wall types

A wall can be made of a variety of materials - but not every wall is sufficiently stable to secure a slope. Possible are among others:

  • Walls of plant rings or plant stones, more here
  • a concrete wall
  • a wall of natural stones
  • a drywall (not mortared stones)
  • a brick wall
  • a wall of embankment stones

In any case, the weight of the slope must always be assessed correctly (the prevailing earth pressures) and the retaining wall for the slope must be designed and secured accordingly. For earth pressures above a certain height (certain steepness and length of the slope) heavy-duty walls must be erected.

Heavy duty wall

Heavy duty walls are characterized in that the wall foot is made particularly wide - usually it is about one third of the total wall height. The very broad running wall can be (but not necessarily) up then rejuvenate. These walls are also called heavyweight walls.

It is important - as with all stable walls - here, too, a particularly stable foundation. A so-called frost-free founding of the foundation (ie a sufficient foundation depth) is fundamental. In addition, the foundation must also be stable enough and the concrete quality must be correspondingly high (C25 / 30 is already prescribed for less loaded foundations, depending on the type of wall you have to go much higher with the concrete quality.

The foundation must also have a gravel layer or gravel layer of sufficient thickness under the concrete to prevent water from accumulating there. Drainage is mandatory in most cases.

Tips & Tricks

The statics of an embankment wall is complicated and the necessary execution of a wall must be carefully calculated. The best way to plan your project is to have an experienced GaLa farmer who can perform the necessary calculations and guidelines for wall thickness, material and foundation. So you are on the safe side.
