Natural stone
is a noble material

It takes million and sometimes billion of years, to develop their charming colors and textures. Since ancient time, carved stone has been considered to be the first construction material and has been considered a sustainable building product.

After the extraction in quarry, the work by artisans and highly qualified people reveals their aspect. A variety of finishes can be applied to carved stone to achieve diverse architectural and aesthetic effects.

No rock, no stone, no block look alike with regards to colors and patterns. Because their uniqueness building stones come from whole over the world.

It has to be attested
by a proven independent control

The stone usually has to have certain properties, or meet a standard specification. The products must be controlled in accordance with the relevant harmonized standards. The Manufacturer should draw up a declaration of performance (DoP) for every products. The CE marking should be affixed to all construction product.

Settled in Belgium more than 20 years ago, in the heart of the European Economic Community, Geo-Topics has dedicated it support to the mining and importers of natural stones and aggregates producers.

From the center of Europe

Outside paving in natural stone

When wondering down a street laid in natural stone, you just get an emotional feeling of well-being. Flagstones reminds you of the mountains, a touch of eternity as the building material is ecological, durable, natural an esthetic. A patio tiled with natural stones is sustainable and mostly maintenance free.

The success of building a comfortable street environment could not be achieved without quality products offer to manufactures and importers of natural stones the relevant information required by builders and designers.

Geo-Topics analyses the products according to the requirements:

  • Identification : micro and macro petrographic description
  • Mechanical tests : Compressive strength, flexural strength
  • Physical tests : Specific gravity, porosity, water absorption, slip resistance
  • Durability : Frost resistance

Masonry in natural stone

A nice ashlar façade reminds the beauty of the middle-age castles. A corner stone around the door or a window, a window sill in natural stone improves the look of the building. A drystone wall enriches the architecture of your garden. Due to costs, today stone veneers are widely used in replacement to solid stone blocks. Whilst the esthetic is important, the durability and stability must also be taken into account.
