In recent years, the building materials industry has developed special adhesives that can be used to connect bricks with almost no visible joints. Thanks to the modern construction method, even amateurs can build durable and solid garden walls. The foundation, which is additionally sealed with a vapor barrier, also forms the basis for this.
Garden walls can also be laid with glue instead of mortar or without glue at all
build foundation
- First mark the course of the wall with sticks and tie it down with a plumb line (€7.13).
- Remove the turf and dig a trench 80 centimeters deep the width of the wall.
- Use formwork made of boards for sandy soils.
- Carefully compact the subsoil with a tamping foot.
- Put about 40 centimeters of gravel in layers in the pit and keep compressing.
- Mix the concrete to be earth-moist and fill the pit.
- Compact the foundation of the garden wall with a tamping foot and smooth it out with a squared timber using a large spirit level.
Adhere to the setting time of the material, which is usually 48 hours. The formwork is then removed. Finally, a layer of bitumen cardboard is flamed as an additional moisture barrier.
The walls
Even if the wall is glued, the first row of bricks must be placed in a bed of mortar. To do this, mix enough mortar, apply a layer about three centimeters thick and place the stones.
Tap them down with a rubber mallet. The bricks must be of the same height and aligned. The material should then set for 24 hours.
It continues as follows:
- Apply the special adhesive according to the manufacturer's instructions.
- Put some glue on the brick, put the layers of glue on top of each other and press the brick lightly.
- Stagger each row of bricks by ¾ or half. A guideline is stretched for precise alignment.
Finally, the end stones are glued to the top of the wall. The gaps between the cover plates must be grouted so that no moisture can penetrate here either.
tips
Depending on the federal state, there are different regulations as to how high a free-standing garden wall may be. Information on this can be obtained from the competent authority. The regulations are often also available online in the municipal development plan.
