Frequently asked questions

Is RMC an environmentally friendly material?

RMC material is made of natural marble, which is extracted from regional quarries. As one of the first production phases is crushing and mixing of stone, RMC doesn’t have specific requirements for the shape of the blocks, and therefore the leftovers from the quarries can be used. RMC also focuses on sustainability during the manufacturing process. All water used for cutting and surface polishing is recycled in our water treatment plant, which saves hectoliters of water every day. One of our internal projects successfully reached the stage where we can reuse selected construction material from demolition, such as bricks, concrete or glass.

Can RMC material be used in a kitchen?

Generally, yes, although it requires special care similar to other natural surfaces such as marble or wood. As RMC material contains approximately 95% of natural marble, it is sensitive to contact with acids (e.g. lemon juice), especially in a combination with strong pigments (e.g. red wine). These can damage surface of RMC material (usually loss of gloss, corrosion or a stain). RMC offers the application of antiacid impregnation for honed surface as a partial protection against accidental contact with acid. Nevertheless, the surface has to be cleaned swiftly and still very aggressive liquids may create a light stain. Regular maintenance with the right cleaning agent (pH neutral) is also a key factor.

Can RMC material be used for exteriors?

RMC material is one of the best options for facades, windowsills and other outdoor applications thanks to its low water absorption and shade consistency. As with other natural materials, dark colors tend to fade faster than light colors. That however doesn’t have any effect on material stability. RMC offers color enhancing impregnation, which significantly helps to keep colors vivid even when the product is installed outdoors.
