Seal the garden wall - you must pay attention to this

Whether a seal on a garden wall is ever necessary, and what different ways to seal it in different places in garden walls, read in detail in this post.

Necessity of sealing

Basically, both the foundations (before the walling) and the wall crown should be covered. This has different reasons.

The foundation is that every wall must necessarily be on a seal. This seal is applied below the first row of stones. This prevents moisture from pulling up from the bottom inside the wall.

The masonry crown, however, needs protection from the weather. This not only prolongs the life of the garden wall, but is also provided for in DIN 1053. The DIN demands that all horizontal wall closures and also all slightly inclined wall closures are to be protected against penetrating moisture. For more inclined masonry crowns, the rule does not apply.

Sealing foundations

It is quite easy to seal the foundations with a bituminous membrane and bituminous thick coating. An elaborate sealing is not necessary here, it is only about fundamental tightness.

Sealing options wall crown

Plastering, on the other hand, is not a suitable way to protect the wall crown from weathering and moisture penetration.

  • sheet
  • situ concrete
  • granite

sheet

The easiest way to seal the wall crown is with zinc sheet. For walls of up to 6 meters in length, this is not a problem, here whole sheets can be used. For walls of greater length, individual parts must be joined together professionally (brazing). Always make sure you have sufficient overhang.

concrete

The covering of the wall crest with a layer of in-situ concrete or with concrete moldings is basically possible. Make sure, however, that the concrete layer has sufficient thickness and enough overhanging of molded parts.

granite

Granite is a very noble form of cover, but it is much more expensive than concrete and sheet metal. Before laying, seal with sealing slurry. In natural stone walls, the bricks should be grouted elastically in such a cover. The granite stones are laid with natural stone mortar on the crown.

Tips & Tricks

A visually quite interesting cover and sealing of the wall crown you can also produce with the so-called monk and nun roof tiles. These roof tiles are a classic, vermörtelte variant and give your wall an interesting, Mediterranean-looking flair.
