The concrete block wall is not only popular because of its relatively moderate price. Bricking up and building with the stone is often easier to implement than natural stone, especially for skilled laypeople. The exactly matching stone sizes and textures allow many types and designs that are created by wall bonds.
Component names and technical terminology indicate design options
When a concrete block wall is created, it consists of a single-row or two-row bond. The offset positioning ensures sufficient stability, as the "predetermined breaking point " joint only ever extends one stone height. The identical stones can be set like building blocks in alternating and different combinations lengthways and crossways to form a masonry.
The following technical terms refer to the individual wall structures and parts of the work:
- Runners are the stones placed along the course of the wall
- Binder are the stones placed across the course of the wall
- Bed joints are the horizontal joints between the rows of stones
- Butt joints are the vertical joints between the individual stones
- Longitudinal joints are the joints between the front and rear row of stones in double-row walls
- Running bonds are stones placed one on top of the other, offset by half the stone length
- The dragging bandage is offset with an overlapping offset of a quarter stone length
Practical tips for bricking up
A concrete wall is built on a concrete foundation. It must be frost-proof (at least eighty centimeters deep) and, if necessary, have efficient drainage.
On top of the set and dried foundation, the first row of stones (wall base) is placed on mortar (€ 7.79 on Amazon *), the so-called chimney layer. The base stones can best be aligned in the thick bed. As with every building, the precision at this point decides on the entire subsequent structure.
The base of the wall must be set according to the selected wall bond. In the case of a dragging bandage, quarter pieces are used at the ends, but this can also only begin in the second row. In the runners' association, the bricks are halved.
The concrete blocks should always be briefly dipped in a water bath and soaked in water before laying them up. This helps the mortar or food to set in peace and fully develop its setting properties.Tips & Tricks The various wall connections that you can create with concrete blocks are mutually exclusive with other types of stone such as broken stone and natural stone, as each individual wall block must be exactly the same size.
