Visnes Kalk
ABOUT US
Visnes Kalk AS operates an open pit mine located on the west coast of Norway. The production is based on processing of crystalline marble known for its whiteness and high calcium carbonate (CaCO3) content and high density eclogite.
Marble from Visnes is a metamorphic rock that consists mainly of mineral calcite, which is a crystalline form of calcium carbonate (CaCO3). It has stable specific gravity of 2,7 tones / m3 and calcium carbonate content above 98%.
The quarry is selectively operated to utilize the material in the most sufficient way, where fine grades are screened out and only pure marble stone is used as a raw material for further processing of marble products.
The company offers several grades of marble and has possibility to mix existing- or produce new grades according to customer needs.
We have long experience in production planning, quality control and logistics that help us to make sure that our high quality products are delivered on time. Our services are reflected in satisfied customers for a number of years.
In addition to marble grades, we produce Eclogite products with high compressive strength (>150MPa) and high average density (3,2 t / m3). Eclogite can be applied in various applications that require strong and heavy rock. Eclogite products are supplied by Visnes Eklogitt AS, a sister company of Visnes Kalk AS. Furthermore, Visnes Eklogitt AS collaborates with Norock & Co AS.
Visnes Kalk AS has 25 employees, as well as a varying number of temporary contractors. The company consists of quarry, marble- and eclogite processing facilities, workshop, packing facilities for bags on pallets and big bags, as well as two shipping quay where the main quay is ISPS certified.
Certifications:

Marble application area
For agriculture,
industry and construction
Marble from Visnes has a high purity (> 98% CaCO3) which makes it applicable for its chemistry, mechanical properties and white and beautiful appearance.
We supply quality products at competitive prices.
Process Industry
Marble is part of several process industries due to its chemistry or color. See Products.
Water Treatment
Marble is used as a filtration mass, as well as regulating pH to improve the quality of drinking water. See Products.
Construction
Marble is part of a variety of building materials. Examples of this are facade stone, decorative marble chips, sandblasting, asphalt fillers. See Products.
Garden Lime
For horticulture, marble can be used as a gem in the form of marble chips or mixed soil in the soil with granulated marble fines. See Products.
Agriculture
Agricultural lime is used to increase the pH value in the soil. Lime is also added as a dietary supplement in animal feed. See products.
Oil and Gas Industry
The oil industry uses marble sand as part of the mixture in the drilling fluid. Marble is soluble in acid, gives little wear on drilling equipment and has a stable density. See Products.
Eclogite applications area
Eclogite, where high density counts
Eclogite from Visnes has a high average density above 3,2 t/m3. This, together with high compressive strength (> 150MPa), provides excellent features for ballasting, overlay and protection of submerged installations.
The relatively high submerged weight gives the eclogite its advantage in achieving stability underwater.
We supply quality products at competitive prices.
Construction
Eclogite is subtile as concrete aggregates with high density. High density gives the concrete advantage Properties in relation to heat absorbing and soundproofing. Eclogite is also an excellent ballast material for constructions. Ratings we offer are between 0-18 inches, these fractions are customized and made after ordering. See products.
Windmills
Eclogite is used as armourstone covering foundations of offshore wind turbines. By using eclogite as armourstone counteracts erosion as well as provides structures and installations protection. Desired grading between 0-18" is produced by order. See Products.
Oil Installations
The high density of the eclogite makes it suitable as stable cover of different oil installations on the seabed. Here either for the protection of vital components against water currents or as shielding against other adverse effects. See Products.
Mass struckture
Eclogite has high compressive strength and is suitable for mass build-up for building and road construction purposes. We produce different fractions of eclogite for this purpose. See Products.
Friction sand
Eclogite in the 2-4mm or 4-7mm fraction is suitable as friction sand on icy roads. See Products.
Pebbel and gravel
Eclogite is used for a variety of purposes within the pebbel and gravel fraction. Examples of this are: Concrete mortar, pipe cover, drainage and reinforcement layers. See Products.
