Set stairs outside - this is how it works

Setting a staircase outdoors - for example in the garden - yourself is not that difficult. There are a few basic things that you should definitely pay attention to. How to do it, and what options there are for building a staircase, read in this post.

Fundamental: the foundation

The foundation is, in the truest sense of the word, the basis of every staircase. It is important to ensure that the foundation of the stairs is sufficiently stable and has a frost-free foundation.

This means that the foundation for the stairs must be excavated at least 60 - 80 cm deep. A layer of gravel or gravel is used as a base, which has to be compacted, and concrete is poured on top. When the foundation has hardened sufficiently, the steps can be placed on it.

The concrete should have a strength of at least B15 and a grain size of 0/16 to ensure sufficient load-bearing capacity. The use of seepage concrete is recommended in all cases.

Instead of a continuous foundation, a strip foundation may be sufficient in some cases, but this depends on the construction of the stairs.

In the case of the full foundation, a stair-like sub-structure is created, which can also be relatively easily combined with other materials (plaster, etc.). ) can be assigned. Correct shuttering is important for the substructure.

Outside staircase with block steps

Block steps are the easiest way to put a flight of stairs. The block steps made of natural stone or concrete stone can either rest on strip foundations or be placed on a solid foundation and a corresponding substructure.

When placing the blocks, it is important to create a slope of around 2% so that the water can drain off sufficiently. Between the substructure is a layer of stone mortar, preferably with trass cement.

It is best to create a drainage below the last step. In this way, the water flowing down can be safely disposed of via a drainage pipe.

Alternative: paving

A finished solid concrete foundation can be covered with any material:

  • Cobblestones
  • flat stones in a mortar (7.79 € on Amazon *) bed
  • Quarry stone

With most materials, however, the step edges should always be made with solid concrete blocks so that the edge does not wear out so quickly.

Tips & Tricks For laying block steps - regardless of the material - you will need several helpers due to the heavy weight. It is best to move the blocks with straps pulled underneath to lift them up.
