There are many associations when it comes to building concrete blocks


To properly build concrete blocks, the type of concrete blocks and the size of the desired wall are important. In the case of single-layer walls, a runner's or trusses' association is masonry, with multi-layered masonry walls are made in a block or cross dressing.

Single and multilayer masonry units

If you want to build concrete blocks, you must plan the desired wall type beforehand. The desired height results from the dimensions of the individual stones plus the joint thickness on the corresponding track. For jointless masonry, pure concrete block gauge is the calculation factor.

Depending on the planned construction of the wall of the corresponding stone association must be determined. For single-layered walls with one stone depth per row, different binder and runners associations are possible.

  • Simple binder bandage (stone length corresponds to wall thickness)
  • Mittlerer Läuferverband (Halved staggered longitudinal arrangement)
  • Sluggish runner association (longitudinal arrangement with offset in quarter steps)

A multi-layered wall can be built in a block or cross bracing. In addition, there are historically created decorative dressings in multilayer masonry such as the Brandenburg, the Dutch, the Flemish, the Gothic or the Silesian Association. Multilayered wild bandages resemble the sluggish runners' associations through the use of quarters, in this case multi-layered.

How to build concrete blocks

  • cement
  • sand
  • water
  • aggregates
  • or
    ready-mixed mortar
  • guide
  • Wooden sticks or pegs
  • plummet
  • setting plan
  • trowel
  • mortar vessel

1. Mark the wall route

Clamp on the front and back two straightening cords along the wall track at the height of the first row of concrete blocks.

2. Sort concrete blocks

Settle the concrete blocks in the correct order according to the setting plan for your chosen masonry.

3. Set base row

Spread the mixed mortar on one side of the set strip foundation in the width of about three dressing units and place the base stone on. After the second stone next to it, continue on above. Place the initial stone of the next-to-side offset row or, for multi-layer dressings, the following runner or binder arrangement.

4. Staged walls

Keep building in these steps and always follow the guidelines accordingly. For vertical control you should mount a plumb bob to the wall ends on a suspension.

Tips & Tricks

You have the option of walling the wall in stages from one side or from both sides towards each other. Frequently and practically is a mixed form with the row walls. Always "fill in" the center of the wall with concrete blocks up to a maximum of one row below the stones already placed on the sides.
