The Diephaus Siola-Kombi is a concrete block with a square cross-section of 12.5 x 12.5 cm, suitable for use as a wall block or palisade. This version, in the color "Autumn Ambiance," is 37.5 cm long, split on three sides, sandblasted on the surface, and coated with PE3 Pearl Effect 3. According to Diephaus, capping, starter, or end blocks are not required.
The stone is aimed at garden owners as well as garden and landscape designers who want to create walls, bed borders or palisades with a stone system; for taller stones in the same style, the Diephaus Siola-Mini is suitable.
According to Diephaus product data for the Siola combination series and installation instructions for wall elements, the following applications and test points apply:
With a single type of stone you can build walls and palisades, and according to Diephaus, the coating repels dirt and, with regular maintenance, protects against moss adhesion for over five years.
The Diephaus installation instructions for wall elements differentiate between construction as a wall and installation as a palisade.
Diephaus specifies an excavation depth of 50 to 80 cm with 30 to 60 cm of frost protection, approximately 20 cm of lean concrete, and mortar leveling. With a layer height of 12.5 cm, this equates to roughly 21 stones per square meter of visible surface, excluding joints.
According to Diephaus, for low loads, an embedment depth of one third of the height is sufficient; for higher loads, palisades are set in lean concrete and individually plumbed.
For higher slope stabilization structures or freestanding walls, Diephaus states that further structural engineering measures, including static calculations, are necessary. You can find more stones in the Diephaus overview .
The information is taken from the Diephaus product data for the Siola combination series in the format 37.5 × 12.5 × 12.5 cm and the Diephaus installation instructions for wall elements (as of 09/26).
