The foundation of the drywall

Especially the 1980s and 90s are synonymous for many building sins that were like to "landscaped" around the building in the garden design. With the trend towards more naturalness, however, one of the oldest forms of human architecture has increasingly found its way into the local gardens: the drywall. Like every wall, the drywall needs such a thing. Unlike a masonry wall, you do not have to create a concrete foundation for it. Nevertheless, there are some special features to be considered. Following you will receive instructions for creating a professional foundation for a drywall.

Numerous reasons for a drywall

Especially the last decades before the turn of the millennium are especially for unnatural materials. It was probably the new technical possibilities that made up to now unusable outdoor materials suitable for building. Below only a small selection of these numerous horticultural sins:

  • pressure impregnated palisades
  • Mossy concrete walls with numerous frost damage
  • Cement stones with frost damage
  • Wire mesh fences and other, unimaginative demarcations

Meanwhile, however, a strong trend towards natural-looking garden design can be seen. The well-kept English lawn to the concrete base of the property boundary with its sterile effect is no longer something for everyone. Instead, preference is given to natural products that are not just harmonious garden designs. Their longevity is often unsurpassed.

The natural stone and drywall - a piece of nature

As a result, the popularity of rock gardens has slowly increased the trend towards natural stone walls. Today, dry stone walls are an important, style-defining element for any garden, which always looks extraordinary and individual. It stands for conspicuousness, but still nestles perfectly in the overall picture of a garden landscape.

Construction of the drywall

The drywall is probably the oldest building that people tend to build. Dry stone walls have been built for millennia and give some regions their special character. The difference to a conventional wall is that for cementing the individual stones neither cement nor other binders or adhesives are used.

The foundation

For stability and stability, the planting of the drywall usually takes place later, because the root system ties the wall downright. Nevertheless, even with the drywall a foundation is needed, on which the wall foot then arises. It does not have to be that deep, though. Also concrete does not have to be used.

Tasks of the drywall foundation

However, it is important to ensure that the excavated foundation is slightly inclined. Since many dry stone walls are filled up on one side, the inclination can lead inwards. Because the foundation also has the task of drainage. Otherwise you can also use natural products for the foundation.

Step-by-step instructions for creating a foundation for dry stone walls

  • Mineral mixture (gravel, gravel) grain size 0/32 to 0/45
  • Construction sand
  • suitable stones for the wall base
  • Excavation (mother earth)
  • Digging tool (pickaxe, shovel, spade, etc.)
  • alternatively mini excavators
  • Compressor, preferably by machine
  • optional guideline

1. Preparatory work

First you have to cut the foundation. Depending on the chosen wall, however, the foundation must look different. If you are on a slope, tilt the drywall by about 12 percent and you have to put the wall base around 50 to 60 percent wider (half on both sides).

For dry stone walls with straight, smooth stones, the foundation is about 10 to 15 cm wider than the wall base, which then corresponds in width to the rest of the wall. The depth of the foundation should be 30 to 40 cm. At the wall closures, the foundation should also survive 5 to 10 cm.

2. Fill the foundation with the mineral mixture

Now the mineral mixture is filled to about 75 percent in the excavation. Then you have to compact the ballast in several operations.

3. Building sand on the compacted gravel

Now a layer of building sand is applied. This should again be 5 to 10 cm. The surface is smoothed out.

4. laying the wall base

Now the largest of the stones used are used for the wall base. Press the stones several inches into the sand bed. Cavities can be filled with a mixture of stones, sand and mother earth. Behind the drywall (uphill or to the inside of the wall) you can already fill with mother earth.

Tips & Tricks

Use stones from your area to build the drywall. The further the transport, the more expensive. With an average drywall (wall thickness 40 cm), you must expect a weight of around one ton per square meter. Consider the desired planting already during the construction of the drywall.
