Garden wall walls - that's how it works

What looks quite simple at first glance is not at all: the walls of a garden wall. That starts with the foundation. With the following instructions, however, the production of a garden wall succeeds easily.

Important for the garden wall

  • Driving wall or embankment wall
  • Height and length of the wall
  • the right foundation

Driving wall or embankment wall

For walls that intercept a embankment or support a slope, special building regulations apply. In addition, such walls are usually subject to approval and should only be planned and implemented by specialist companies.

You can also make simple dividing walls in the garden yourself as a do-it-yourselfer.

Height and length of the wall

There are no generally binding legal provisions here. In many municipalities, however, the respective building authorities must be aware of this. There it is also determined whether the planned length, position and height of the wall is permissible.

The neighbors can also exercise a right of objection if necessary. So it makes sense to vote in advance.

The right foundation

The foundation must be dug at least 60 - 80 cm deep to ensure a frost-free foundation. It is filled with a layer of gravel to prevent the free-standing wall from freezing and a base layer of around 20-25 cm of screed concrete.

The foundation floor must be compacted with the vibrating plate (€ 414.00 at Amazon *). Depending on the type of stones used and their weight, the base course may need to be reinforced.

Step by step to the garden wall.

  • Bricks
  • suitable mortar (€ 7.79 at Amazon *) (for natural stones: natural stone mortar!)
  • Screed concrete
  • Gravel (best 0/32)
  • Construction film
  • possibly. Bituminous board
  • Grout for outdoor use
  • Plate compactor
  • Concrete bucket or tub to mix
  • Stirrer for mixing
  • Mason's cords for marking
  • Shovel and spade
  • trowel
  • Spirit level
  • plummet

1. Build the foundation

Dig the foundation trench 10 cm longer and wider than the planned wall, compact the soil with the vibrating plate and pour in gravel about 40 cm high. Then pour screed concrete, cover with construction film and allow to harden.

2. Create a wall

Mark the course of the wall exactly with mason's cord. Lay the thick bed and align the first row of stones exactly. Then build up the ends of the wall, then the rest of the wall. Check again and again with the plumb bob and the spirit level.

3. Seal joints

Scrape the masonry mortar out of the stone joints and grout the entire surface with a suitable joint mortar for outdoor use. So no water can get in.

Tips & Tricks To prevent moisture from being drawn up into the wall, a layer of bitumen cardboard can also be worked into the screed concrete layer.
