The reason to think about a wall in your own garden is often a difference in height on the grounds. With retaining walls, a hillside garden can be skillfully terraced, so that you have as many flat areas as possible. In terms of design, however, garden walls are also a benefit for level gardens: be it as visual protection, effective noise protection or simply as optical separation elements to divide the garden into different rooms. In addition, low garden walls have proven themselves as bed surrounds, for the construction of raised beds or simply as seating in the garden.
The question is: what kind of Wall fits your garden and meets your expectations? Finally, there are different construction methods and different materials from which aesthetically pleasing garden walls can be built. Here we introduce you to the most common types of walls.
Classic Garden Walls
Garden walls are classically constructed of concrete, clinker or natural stone using mortar. Especially with higher walls, which can also serve as a visual protection, one should prefer muddled variants, because they can be constructed much narrower than walls stacked without mortar – the so-called dry walls
Depending on the height of the garden wall, a concrete foundation is required that projects about 80 centimetres deep into the ground. Construction experts speak here of a so-called Frost-Free Foundation: in central Europe, the ground never freezes to a depth of 80 centimetres, so that so-called Frost rises due to frozen ground water, which could cause cracks in the foundation and masonry, are not to be feared.
To build a garden wall with mortar
Only laymen with craftsmanship should build a ruined garden wall themselves. Above all, the correct portioning of the mortar requires practice, because each stone row must be precisely aligned in its position on a horizontally stretched bricklaying cord, so that the wall becomes straight. This is especially true for the first stone row, because even small unevenness can only be compensated by larger joints, which disturb the appearance of the garden wall and in extreme cases can even impair stability.
With regular layer masonry, the precision requirements are still comparatively low – you need even more experience and Routine if you want to build a so-called irregular layer masonry made of stones of different heights or a garden wall made of marred quarry stone masonry.
When building a garden wall with mortar, proceed as follows :
After you have correctly measured and staked the wall, excavate the trench for the Strip Foundation 80 centimeters deep. The width depends on the desired wall width.
For the upper edge of the foundation, you should build a formwork made of wooden boards, which is exactly horizontal, right-angled and aligned at the appropriate height above the foundation. Ideally, the formwork top edge is exactly at the level of the floor or slightly below it.
Now fill the soil-moist concrete up to the top edge and compress it with a hand-held tamper. Then peel off the surface with a wooden board and possibly smooth it with a bricklayer trowel or a smoothing board. Now the foundation has to harden for a day.
Start building the actual garden wall by spreading a thin layer of mortar on the concrete foundation. Then roll out a bitumen web on the mortar as a so-called capillary barrier, which should be approximately as wide as the foundation. This is followed by another layer of mortar.
Now put the first row of stones. It must be precisely aligned with a spirit level and a stretched bricklayer cord. Corrections can be made with a rubber hammer. Before placing each new stone, place a dab of mortar on the narrow side surface adjacent to The Last already placed stone to close the so-called Impact joint. Remove the mortar that springs out with the trowel so that no larger mortar remains dry on the visible surfaces of the garden wall.
