What are polygonal slabs?

The very technical-sounding term Polygonal Plate does not do justice to the beautiful, vibrant Mediterranean visual effect in any way. The word "polygon" comes from ancient Greek and translates to "polygon", meaning a geometric shape with many corners. In the case of Polygonal Plates, they are irregular or asymmetrically shaped polygonal plates made of natural stone. Irregular here means that all the flagstones have an individual shape, making each one unique with different or irregular edges and many corners, varying sizes, and surfaces. Truly a completely natural product.

Enjoy a splash of color with colored quartz gravel joints between your polygonal slabs

Aside from the shape, polygonal slabs or natural stone patio slabs are also individually characterized by color, grain, and surface, emphasizing the lively and natural southern flair.

In principle, broken slabs are laid like a mosaic, and the resulting gaps (joints) are also irregularly grouted. This emphasizes the intentionally loose character and creates an authentic and harmonious interplay.

By the way, my wife inspired me to more color joy and individuality when it comes to joints and mortar. You can now also enjoy the result. Our self-developed colored joint mortar is available in 14 different colors. This way, you can let your creativity run wild in the design of your patio or pool landscape or garden and indulge in colorful installation.

Polygonal slabs are intended for what purpose, where do you use the stones, or what do you do with polygonal natural stone slabs?

Of course, your imagination knows no bounds and you can implement any projects that come to mind. Here are the most common applications for polygonal slabs made of natural stone, and I will also show you some examples for your inspiration. Not all materials are suitable for every purpose, as there are different strengths and properties. For example, areas that are driven on by vehicles require stronger stones and a suitable substructure to prevent your polygonal slabs from breaking under the load later on.

I cordially invite you to contact our specialist advisory team for your specific project from Monday to Friday between 8 am and 4 pm at +49 (0) 3332 26 70 78 27. Here you can ask all your questions. Outside of our business hours, feel free to use our contact form.

Here are examples of what polygonal slabs can be used for

There are countless possibilities and applications, your imagination knows no bounds. Polygonal slabs are suitable in the garden, as terrace, edging, paths such as garden paths or stepping stones. As flooring, edging for pool, swimming pool or pond. For your barbecue area, as seating areas, garage driveway, cladding such as cladding stones for walls and fences, as rustic wall cladding indoors and outdoors. But of course also as a balcony and entrance to the house, just to name a few examples.

Depending on how the sun or moon shines, the different surfaces unfold their magic through gentle grainings, bright lines, and dark inclusions depending on the time of day or night. The diversity of the various quartzite stones is always impressive when quartz veins and crystals shimmer in the light and fine veins become visible.
Before I list the world of polygonal slabs for completeness, I would like to briefly explain why we mainly focus on outdoor areas and why certain types of polygonal slabs are not suitable for this purpose. If you want to do something particularly well, you focus. This has the advantage that you become a specialist in polygonal slabs for outdoor areas and can pass on the purchasing advantages to your customers.

What natural stones are polygonal slabs made of?

These natural stone types of polygonal slabs are available (sorted by hardness):
Granite, graywacke, quartzite, porphyry, slate, basalt, gneiss, marble*, limestone*, and sandstone.

Polygonal slabs made of natural stone are a popular alternative to tiled surfaces and are used indoors and outdoors. They are more durable than tiled surfaces, as they are less susceptible to damage and are easier to clean. In addition, they are easy to install and create a harmonious atmosphere.

Our absolute favorite natural stone: Quartzite polygonal slabs

We love quartzite and there are many good reasons for that. Quartzite is more resistant than granite, totally insensitive to impurities such as dirt and stains, robust, easy to care for, and durable. The abrasion resistance of quartzite is unparalleled, as is its weather and frost resistance. There are quartzite broken stones in thicknesses ranging from 2 to 5 cm with hardness levels of 6 to 7. This wonderful natural stone absorbs very little water, is characterized by its Mediterranean color scheme, and is the only stone with the so-called quartz glimmer effect - a real plus that always attracts attention.

And here you have the selection and description of 10 types of quartzite polygonal slabs at a glance


Antares - relatively smooth natural surface in pink, accents with reddish brown tones


Auralis - relatively smooth natural surface in yellowish tones


Jasmares - relatively smooth natural surface in greenish gray


Polaris - relatively smooth natural surface in shades of white and light gray


Copper - Shades in gray silver shimmering and cream tones; occasionally warm brown tones; unobtrusive, natural; modern ambiance; exclusive; high quality

Lemuria Light

Lemuria Light - Soft red tones, strong, earthy brown; occasional inclusions of metallic gray; boundless variety of facets; fine, light lines, dark inclusions; antique charm


Kallisto - unique color play; Mediterranean look; creamy, gentle yellow tones; strong earthy brown; rustic; traditional; modern and luxurious; shimmer enchantingly in sunlight

Deep Sea

Deep Sea - elegant, dark, calming anthracite; few lighter inclusions such as quartz veins or quartz crystals; the slabs look as if they come straight from the depths of the sea


Violet - warm, sandy yellow, beige, and brown tones; makes the sun rise; holiday mood; noble; when light falls on the slabs, they shimmer in a soft violet


Clara - expressive beige color tone; classic style; interspersed with fine darker inclusions. Highest quality; graceful elegance; exclusive ambiance


How are polygonal slabs laid?

The laying of polygonal slabs is done on a flat surface after the subsoil has been prepared. Irregularities should be repaired and the subsoil cleaned before laying the slabs. The polygonal slabs are arranged in a pattern and grouted with grout. It is recommended to maintain a joint width of at least 10 mm. After all slabs have been laid, the floor can be sealed with a natural stone impregnation to extend its lifespan. For the laying of polygonal slabs, we have developed special terrace packages COMPRESA that include both the slabs and the grout, quartz gravel, and the impregnation.

So you prevent cement haze and at the same time relieve the environment

There are numerous instructions on the internet for laying polygonal slabs, which, with few exceptions, are based on a cement or concrete base. This is not environmentally friendly due to the necessary sealing and ultimately complicated, as a corresponding slope and drainage must be created. The well-known problem of cement haze then has a negative impact on the beautiful and desired appearance of the polygonal slabs. The cracking of the concrete slab over time causes further difficulties. For this reason, we have developed a solution that is practical and optimized to relieve our environment. Furthermore, it makes cement haze and cracking impossible because we do not use cement or concrete. Our cement-free installation method with quartz gravel and resin is water-permeable and directs water through the joints over the quartz gravel layer directly into the soil. A sensible, simple, and environmentally friendly solution that does not require sealing.

Which substructure for polygonal slabs?

The foundation here is the so-called concrete recycling, which essentially consists of granular concrete rubble and should have a height of at least 15 cm in the previous excavation. We have chosen this base layer in combination with quartz gravel for its excellent compaction ability and water permeability. For those who like to do DIY projects, we have created a Do-it-yourself (DIY) guide.

If you prefer to hire a specialist company

Within the new federal states, we are able to professionally install your polygonal slabs starting from 100 m² upon request by a trained in-house installation employee. This way, you have everything ready from a single source. Outside the new federal states, we have the following recommendations for you.


It's a bit like baking a cake. You just need the right ingredients and a recipe. You mix a "dough", pour it into the "mold", and smooth it out. Except here, you don't need an oven but 24 hours in the fresh air. Then sweep away any remaining debris. Done! Sounds simple, and it is.

And here is the ingredient list for 4 m²
25 kg Colorquarz / Grout
• 1 kg Resin
• 1 mixer
• 1 mortar bucket
• 1 smoothing trowel
• 1 hand broom with stiff bristles
• 1 broom

How to grout polygonal slabs?

DIY guide to laying polygonal slabs: The "recipe" for grouting rubble stones
1. Mix Colorquarz and Resin with the mixer in the mortar bucket until all grains have a uniform shine and a homogeneous "rolling" mass forms
2. Pour the mass onto the laid natural stone slabs
3. Spread the mass on the surface with the smoothing trowel, which then "rolls" into the joints
4. Sweep away any remaining grains with the hand broom
5. Let it rest for 24 hours
6. Sweep away any remaining residue with the broom.

What are the advantages of polygonal slabs compared to other floor coverings?

A major advantage of polygonal slabs is their natural beauty and durability. Compared to other types of flooring, they are often more affordable and easier to install.

Which joint mortar is the best for polygonal slabs?

For grouting polygonal slabs, we recommend a grout based on synthetic resin. This grout is particularly water-permeable and resistant to weather influences and mechanical stress. Our grout can be matched to the color of the polygonal slabs to achieve a harmonious overall appearance. When choosing the grout, make sure it is suitable for outdoor use.

Can I use rock salt on polygonal slabs in winter?

It is not recommended to use rock salt on polygonal slabs, as salt can attack and damage the surface of the slabs. The chemicals in salt can also penetrate the stone and cause long-term damage. Instead, you should use alternative methods for snow removal and ice control, such as shoveling snow or spreading sand or gravel. However, if you are forced to use rock salt, make sure that the polygonal slabs are properly sealed and that the salt is removed immediately after the snow has melted.

Are polygonal slabs drivable?

Polygonal slabs are generally suitable for pedestrian traffic and light vehicles such as bicycles or scooters. However, for use on drivable surfaces such as driveways or parking lots, special, thicker, and more resistant stones are better suited. If you want to ensure that your polygonal slabs are drivable, you should seek expert advice from a stonemason or a landscaper to ensure that you are using the right stones and laying techniques. We have extra massive stone slabs in our range for this purpose.
