CONCRETE

 

 

What are the advantages of concrete 2.0?

Concrete 2.0 is reinforced with glass fibers that improve its mechanical properties. Compared to the concrete which is usually used e.g. in construction industry, concrete 2.0 is much stronger in both tension and compression. Therefore we can produce boards just 15 millimeters thin with a length of up to 2.6 meters. The proof of its toughness is, for example, our tiny ring easily withstanding any fall to the ground.

We use the highest quality raw materials that allow working with concrete at the edge of current technological possibilities. We have a few our own manufacturing processes, individual for each product – for surgically precise jewellery production or casting a table top we always need an individual concrete mix and specific after-treatment. 

For detailed information on concrete 2.0, read more on the web.

Isn’t concrete 2.0 too heavy?

Thanks to the fibers we add to a basic mixture, our concrete has extra strength. For this reason, it is possible to use less material and produce elements just 15 millimeters thin. The final product with such thin components is then several times lighter than a product being casted in a standard procedure. For example, one of our Wally earrings weighs just about 1.5 grams, which is equivalent to 5 small office staples. Most of our countertop washbasins do not exceed 20 kilograms. Even our largest table Lucca can be carried by several people without a need for a special technique. 

Is concrete 2.0 protected from absorbing liquids?

Yes, all Gravelli products are treated with several layers of high-quality impregnation to withstand long-term contact with water, coffee, red wine or even a whole-year outdoor exposure. Similar to wood, glass or stone, concrete is also a natural material that changes slightly over time and gains its unique patina. Thanks to its treatment, its resistance is significantly increased and Gravelli products do not need any further special care during use.

Do your products require special care during their maintenance?

Gravelli products can be maintained in a standard way, e.g. using a sponge and a degreasing agent. Only two rules apply: 1) you must not use lyes or abrasive detergents and materials such as abrasive pastes or scourers 2) the second rule applies only when a whole-year outdoor use of your product – never cover the product with any sheet. Let it snow and rain on it and do not worry, everything will naturally dry up. If the darker spots appear, it is just a common reaction in a microporous surface. They disappear right after all excess water evaporates. In general, concrete is not recommended for staying in a long-term exposure to both damp and acidic environment at the same time.

Will the surface remain the same in twenty years? 

In terms of its quality – yes, in terms of its look – not. Applying the standard care, the surface characteristic will remain the same and your product will not need any special treatment even then. In addition, the product will gain a unique patina creating an absolute original from it.

GENERAL

 

 

Can I buy just a concrete mixture from you?

Production in Gravelli means a strictly controlled process which cannot be realized in any home environment. That is why we do not offer just a basic concrete mixture. If you are interested in custom items, visit Gravelli Bespoke and contact us.

Do you have samples available?

Yes, after receiving basic information about your project, we will inform you about an order or production options. If needed, we will send you an appropriate concrete sample kit. 

Where can I see your products in person?

Our products can be seen at authorized dealers and partners of Gravelli. All locations are listed in the Dealer Locator on our website. 

Upon prior arrangement, you can also visit Gravelli Showroom and Manufactory (Pod Harfou 3, Prague 9, Czech Republic). If interested, please first contact us.

I have an interesting project in mind. What stages can you execute in Gravelli? 

In Gravelli, we can execute a new project from the initial design to the very end. Designing a project, creating molds, leading the project through all production stages and delivering it in the required amount to the required location. With more information about your project or wish, you can contact us via e-mail or telephone.

How long does a production of a new product last? Can you speed it up?

The production usually takes five weeks. A material and molds are prepared, then a rough product rests, it is cut, polished and impregnated (just the impregnation stage takes about 14 days). In order to maintain the highest quality of each product, it is necessary to respect every stage of the production, thus the whole process cannot be speeded up.

Several pieces of the most Gravelli products are usually in stock. For more information about their individual availability, please see the relevant product sites on our web

Do you ship your products abroad?

Yes, all Gravelli products originate in one manufactory in Prague, but they are then shipped to various stores or architectural projects the world over. Abroad, you most probably meet our products at Gravelli authorized dealers or partners. You can easily find the closest one to you in our Dealer Locator. To buy abroad, you can also use a direct purchase via Gravelli e-shop.

What colours of concrete are available?

All Gravelli products are available in gray and anthracite (for all washbasins and some objects also in sand) colour that respect and highlight a nature of the material. Any other possible variants are always listed on a relevant product web site.

Every basic concrete mixture is prepared individually, therefore we cannot guarantee the perfect colour uniformity of different products made in different days. 

Do you work with other materials?

We focus exclusively on a production of concrete elements. Other materials such as wood or metal are processed into our products just as their components. We usually supply e.g. metal brackets to wall-mounted washbasins or metal table bases. 

Do you make concrete screeds and floors?

No, we produce and supply only spatial objects, not any surface solutions such as tilings, cast floors or concrete screeds.

LIFESTYLE / JEWELLERY

 

 

Are your concrete rings comfortable to everyday wear?

Yes, to make the result both beautiful and absolutely comfortable, our jewelers dedicate several hours of hand cutting and polishing to every piece. The ring is then pleasant to the touch and thanks to its high-quality surface protection, it still looks perfect long-term even after everyday use. Inside there is a thin metal ring for greater strength and permanent shape. 

Can I return the purchased jewellery?

Jewellery purchased via Gravelli e-shop can be returned within 14 days without giving a reason. Shipping costs are covered by a buyer. If a customized jewellery (e.g. engraving) or if purchased personally in Gravelli Showroom, no refund or return without giving a reason is possible. 

Can you customize jewellery? Is it possible to engrave something on the ring?

The only possible jewellery adjustment is an engraving on a ring's inner side. Up to 15 characters (e.g. date or name) can be engraved there based on your wish. Other custom jewellery adjustments are not available at this time. 

How long does a production of a new jewellery last? 

Handmade jewellery production requires several days of work – most of it is usually done within 1 week. Right from its silicone mold, each Gravelli jewellery goes directly to the hands of our experienced jewelers. They hand-cut it and polish it several times to the desired look, gentle surface and shape comfortable for everyday wear. After its surface impregnation matures, the jewellery is ready for sale. Most of our jewellery are usually in stock in several items, therefore we can ship them right after your order. 

Does Gravelli ring keep its shape and size over time? Does a heat or cold affect it?

In each Gravelli ring, a thin external layer of concrete is supported by a firm steel base. Thank to this fixed connection, its shape and size are constant and common temperature fluctuations cannot affect it. 

Is Gravelli ring resistant enough? What if it falls to the ground?

In each Gravelli ring, a thin external layer of concrete is supported by a firm steel base. Thank to this fixed connection, its shape and size are constant and the ring easily withstands even a vehement fall to the ground. 

What is the packaging of purchased jewellery?

Excitement and surprise go hand in hand with our jewellery, making happy both yourself or someone close to you. So in Gravelli, we start right from the packaging. In the case of Gravelli jewellery purchase, you will receive a branded gift cassette containing an original concrete box in the same colour of concrete as the jewellery in it. 

 

 

OBJECTS

 

 

How much does a concrete table weigh? Can I carry it?

Thanks to the fact even our largest table top (2.60 x 1.10 m) can be made just 15 millimeters thin, the weight of Gravelli products is acceptable and they can be usually carried in three or four people. The weight of a specific table depends on its type and dimensions and is always displayed in a technical description of each product. For example, the weight of our largest table Lucca (with its table top dimensions 2.60 x 1.10 m) is 202 kilograms, including its steel base. 

Can I use Gravelli concrete product outdoors during whole year?

Yes, our products do not mind long-term outdoor exposure any time of a year. The only condition that must be obeyed is not to cover it with any sheet – not even during winter, in the rain, snow or hot sun. If not covered, concrete can easily withstand any common external conditions. 

For detailed information on concrete 2.0, read more on the web.

Is the surface smooth? What variants do you offer?

Yes, the surface of Gravelli products can be perfectly smooth. We can make four different surface structures (smooth, industrial, raw, slate), always in the most suitable way for the use of a specific product.

What is the load bearing capacity of your table?

All our table designs are based on statistical calculations to be able to bear a standing man of a common weight (cca 100 kg maximum). Under the firm concrete table top there is a solid iron base, ensuring its high load bearing capacity.  

How can I clean the table?

Gravelli tables can be maintained in a standard way, e.g. using a sponge and a degreasing agent. Only two rules apply: 1) you must not use lyes or abrasive detergents and materials such as abrasive pastes or scourers 2) the second rule applies only when a whole-year outdoor use of your table – never cover the table with any sheet. Let it snow and rain on it and do not worry, everything will naturally dry up. If the darker spots appear, it is just a common reaction in a microporous surface. They disappear right after all excess water evaporates. In general, concrete is not recommended for staying in a long-term exposure to both damp and acidic environment at the same time. 

For detailed surface maintenance information, read our Surface Maintenance Manual.

What if I spill something on the table?

Thanks to several layers of high-quality impregnation, the concrete surface is deeply protected against soaking liquids, coffee or red wine included. If you spill something on your table, just wipe it using a sponge and a degreasing agent. If darker spots appear, it is just a common reaction in a microporous surface. They disappear right after all excess water evaporates.

How to install a lamp?

See the detailed installation manual included in a packaging of every lighting. The installation itself is simple, the only thing you need to keep in mind is the perfect tightening of all the security elements. If you are not sure about anything, ask an expert or contact us

 

 

BATHROOM

 

 

Can you customize washbasins?

Dimensions of all our countertop washbasins are fixed and the design of their molds does not allow any modification. In the case of wall-mounted washbasins, only the internal sink dimensions are fixed. We can adjust external dimensions based on your personal needs. For more details on custom made products, feel free to contact us.

Together with a purchased washbasin, do I get a fitting drain? 

Yes, we usually supply the drain – ClickClack within the packaging. If you need to use your own ClickClack, we gladly advise your choice, however all is standardized for common drains. For more information, you can download a technical drawing for a specific washbasin on relevant product web sites. 

How to install a washbasin? 

See the detailed installation manual included in a packaging of every washbasin. Together with a wall-mounted washbasin, metal brackets for wall mounting are included in the packaging. In this case it is important to check that the wall is load-bearing. In the case of countertop washbasins, the installation is easier, just make sure it is in a perfectly centered and balanced position. If you are not sure about anything, ask an expert or contact us.

Why is a wall-mounted washbasin more expensive than a countertop one?

Fixed dimensions of countertop washbasins allow us to produce them in an easier way of casted concrete with a repeated use of standardized molds. To keep a weight of wall-mounted washbasins low, we need to create their molds separately for each piece and use a sprayed concrete technology. That is the why such production is more demanding and expensive. On the other hand, it allows a slight modification of their external dimensions, if needed.
