Stone carpet in the office

First and foremost, the area of application determines the pricing. However, the costs depend on many different factors, including

• the type of binder required

• from the primer

• the choice of skirting boards, for example if these are also made of quartz gravel

• from the labor costs of the professional installer

• the size of the area to be laid

In outdoor areas, the costs are higher because the substrate is sealed and a special binder is used.

In most cases,
colorquartz
or
marble gravel
is used for the production of stone carpets. However, there are considerable differences in quality here, for example in the proportion of dust in the material or in the types of marble used.

Colored quartz is available in the following grain sizes:

• 1–2 mm

• 2–3 mm

• 3–4 mm

Marble gravel is available in the following grain sizes:

• 1–4 mm

• 4–8 mm

• 8–15 mm

Of course, the choice of gravel grain size has an effect on the laying thickness of the gravel floor.

The laying thickness of the floor depends on the gravel grain size and the area of application. Normal quartz gravel with a grain size of 2 – 3 mm can be laid indoors – for example in offices – with a thickness of 6 mm.

An installation thickness of 8 mm is used outdoors and on stairs indoors due to the load.

Finally, 10 mm of material is applied to external stairs.

Vertical surfaces such as risers, skirting boards and walls are always laid in 6 mm.

The larger the grain size of the gravel, the higher the installation height of the floor covering. This means that more gravel and additional binder is required per m². The price increases accordingly.

The primer forms the bonding bridge between the building structure and the gravel floor. The material can be applied to almost any substrate, for example tiles, wood, stone, concrete and metal. Different substrates require different preparation steps.

On tiles and metal, for example, a primer is required to give the smooth surface stability during installation.

On porous stone and absorbent screed, the appropriate primer must be used to prevent the binder from being absorbed, which is intended to ensure that the pebbles remain in place.

To coat wooden planks with a gravel floor, the movement of the planks against each other must first be stopped. To do this, the installer first applies a mesh mat to the wooden floor. Once the filler has dried, the gravel floor is applied.

Especially in kitchens and
bathrooms
, the gravel floor should be fitted with a pore seal for hygienic reasons. It prevents leaked, sticky liquids from penetrating the stone structure. While it is difficult to remove liquids that have penetrated an open floor, the pore seal enables
effortless cleaning
by wet mopping.

Dogs, cats and co. feel much more comfortable on the textured surface than on smooth floor coverings such as tiles or laminate, as they do not slip on stone carpets. However, it is advisable to cover the floor with a pore seal to ensure an easily wipeable surface.

• High drainage capacity due to open-pored structure

• Quick drying in sun and wind

• Easy to clean and self-cleaning

• 100% frostsicher

• UV-stabil

• Gentle, massage-like walking comfort when walking barefoot

The most important thing when laying gravel floors in outdoor areas is preparing the substrate. This ensures the durability of the finished floor.

On the one hand, this is because a primed subfloor provides significantly increased adhesion for the filled gravel. On the other hand, a sealing layer keeps rainwater away from the building structure, for example, which supports long-term durability.

Options for sealing building structures are

• Sealing using a resin seal with a sealing membrane
• Sealing using a flex sealing slurry

In order to drain rainwater effectively, the floor covering is laid with a gradient of at least 1.5%.

In outdoor areas, the stone carpet is always laid as an open system to ensure drainage capacity and thus the run-off of rainwater. This makes them 100% frost-proof and therefore ideal as
pool surrounds
and as a covering for balconies, terraces, entrance areas, outdoor steps and loggias.

We would like to point out that we do not recommend stone carpets in the direct shower area. The reasons for this can be found in the basic structure of the floor and the wet room. Just as the tile adhesive under a tile does not form a completely flat surface without air pockets, pores also remain underneath a sealed stone carpet.

If, after years, a silicone seam leaks and water from a fitting, for example, penetrates between the wall or floor covering and the seal of the building structure, the transparent pore seal reacts with the water and forms white stains. As these occur underneath the seal, they cannot be wiped away or removed by drying.

This is why insurance companies do not classify stone carpets as suitable for wet rooms and do not replace such coatings in the event of damage. We therefore recommend microcement coatings for showers. With these, there is no water-bearing layer between the floor covering and the substrate, so there is no risk of moisture penetration. Due to the many customization options for microcement, it can also be combined with stone carpeting. Just get in touch with us.

A staircase coated with gravel already has a slip resistance class of R10 after installation.

The slip resistance class can be increased to R11 or R12 using special sealants.

Depending on the type of staircase, renovations are possible within 3-5 days.

All our gravel floors use natural stones as the base material. This is why many people also refer to gravel coatings as natural stone carpeting.

The gravel is available natural and colored.

A professionally laid floor can practically only be destroyed by chemical stress or under the influence of enormous mechanical forces. It can therefore be assumed that a well-maintained floor will last for several decades.

A separating layer can be worked into the floor coating during installation. This additional step during installation makes it very easy and effortless to remove the gravel flooring.

Mica additives and various gemstones can be added, but this represents a further cost factor.
