Laying polygonal plates resilient, durable and decoratively

Polygonal slabs create an attractive floor covering that is unknown to the sobriety and severity of the rectangular and evenly laid tile and slab floors. The floor pattern and picture put together like a puzzle is always unique and personal taste is manifested through the individual laying.

A floor made of polygonal plates takes a lot of preparation

Polygonal slabs can be laid on a foundation made of sand, gravel and concrete or laid out loosely in a bed of gravel or sand. The loose version is usually laid so that it is permeable to water, while concrete is waterproofed.

Polygonal plates are always grouted on the wall to create a smooth plane. It is common to all laying methods that the preparation of the "puzzle " is decisive for the visual attractiveness. The following basic ideas and guiding principles help to arrive at a unique polygonal floor covering:

  • The joints should not be wider than an inch at any point
  • Joint nests are quickly perceived as hole-like disruptions to the overall picture
  • In individual cases, fragments can be "made to measure" with a carpenter's hammer
  • Expressive grains and textures are more noticeable on larger stones
  • Combined rocks should be related (igneous or sedimentary)

Lay out patterns, puzzles and distribution in a dry run

Polygonal plates develop their charm through their irregular shapes. In order to create a good layout, to keep the joints no wider than a centimeter and to prevent joint nests, dry running is organized as follows.

1. Four plates or stones with halfway right-angled corners are assigned to the corners
2. Plates with a straight edge are lined up on the surface edges and distributed sensibly. This step is not absolutely necessary if, for example, a garden path with open fluttering edges is planned.
3. If the "frame " has emerged, the puzzle starts. After completion, the plates are numbered with pieces of crepe adhesive tape or attachment
4. The polygon plates are stacked on the edge, starting in the middle. Ideally, an imaginary funnel is followed. If it has to be stacked for space reasons, the order from the inside to the outside is particularly important to encounter the plates in the correct order when laying.

Visible or invisible edge attachments

Instability occurs mostly on unpaved edges of polygonal floors. If there is no "natural " limitation like a wall and the edges are free in bedtime, soil or lawn surface, it should be attached. It is a matter of taste, whether the same or another rock is chosen for edge attachment.

Usually the edges are made of rectangular plates or stones. In principle, it is possible to retain the irregularity of the polygonal structure at the edges as well. The irregular pieces are set in a kind of fluttering orientation, being thicker than the panels of the remainder of the surface. If they protrude several centimeters deeper into the ground, they function as a fastening without being perceived as such.

I have an alternative hidden edge fastening made from a concrete or mortar strip (€ 7.79 at Amazon *) that is pulled up to about half the depth of the joint. Over this, concealing connections such as lawn or plant soil can be distributed.

In the case of visible fastenings in circumferential tape form, the direction of the water drainage can be controlled by placing it in an elevated position. Raised edges all around should be avoided because they are safe tripping hazards.

In order to additionally improve the stability of the entire floor with discreet and delicate edge fixings, binders such as synthetic resin should be added to the laying mortar. Depending on the type of rock, trass cement may be the better choice.

Joint leveling and slopes

In some cases, good water drainage is much more difficult to establish on polygonal slab floors than on other types of tile and slab floors. Some natural stones have an uneven surface shape. Slate is the most typical example. With these rocks, the upper end of the cutting edge is decisive for the horizontal alignment in all directions.

Joints must be filled flush on all edges. With increasing surface unevenness, the incline of the laying surface should be increased. As a guideline, a two-degree gradient in the direction of the water flow is defined. Recessed joints and three-dimensionally varying stone surfaces should be provided with a three to four degree gradient.

Basic rules apply to the direction of inclination. If the stone surface is adjacent to a building, the slope must always move away from it. A slope running parallel to a house wall can only be implemented in special cases. In this case, however, a drainage system or drainage system is indispensable, which in turn leads away from the building at an incline.

Paths, paths and squares should be inclined in a sideways direction. The drainage must be considered. Loose potting soil in beds is quickly rinsed out with just one pour. Grass and lawn can literally "drown". Often, narrow edge fastenings made from a small "stone band" represent the best water drainage system.

Tips & Tricks Calculate the preparation time that you need before you can actually start laying the polygonal slabs, about two hours per square meter of floor area. The laying then costs about another hour per square meter.
