Hollow blocks are now a very common building material made of concrete or lightweight concrete. Even as a do-it-yourselfer, you can get along well with it. Read here what you need to consider when laying.
Hollow blocks for various purposes
Hollow blocks usually consist of concrete or lightweight concrete and are used for different purposes - for example as foundation stones for cellar walls, which are then filled with concrete. Hollow blocks are also made from sand-lime brick or clay.

The masonry is relatively easy, hollow blocks are also good heat-insulating thanks to their air chambers and easy to work with, because you can quickly and easily cut them in half or into thirds with a mason's ax.
Step by step to the wall made of hollow blocks

- Mortar (€ 7.79 at Amazon *)
- Bituminous board

- Spirit level, tape measure
1. Prepare the foundation layer
In order to prevent ascending moisture from the ground, first attach a mortar layer, lay on a layer of bitumen cardboard, and recall a thick mortar layer again.
2. Setting the first stone
Put the first stone on the mortar bed, and set it exactly by using the spirit level. Then they tighten a guideline as a so-called escuts.
When you put the next stone, bring it to its head side - where it stops at the first stone - also a layer of mortar. For stones with groove and spring connection eliminates the mortar layer at the head of the head.
3. Continue the stones
You can fall back on walls on a different wall design from runners and binders, depending on which load-bearing capacity you need.
Runners are stones in the longitudinal direction of the wall, binders are transversely bricked stones. Depending on the pattern of runners and girders, a different wall bond is created.
4th. Stair-like preparation for a more precise escape
In order to be able to keep the alignment more precisely, always brick the individual rows in front of them like stairs. Make sure that the mortar joint is as close as possible to one centimeter.Tips & Tricks With hollow blocks, the stone height is always a fixed measure - precisely so that four rows of stones with a layer of mortar in between always result in a wall height of exactly one meter. That makes planning the wall easier for you.
