Visnes Kalk

What Visnes Kalk does

Visnes Kalk AS is a Norwegian, family-owned industrial mineral producer founded in 1904, operating an open-pit quarry and integrated processing facility in Lyngstad on Norway's west coast. The company extracts and processes crystalline marble with >98% CaCO3 purity (specific gravity 2.73 t/m3) and high-density eclogite (>3.2 t/m3, >150MPa compressive strength), producing a portfolio of graded products including agricultural lime (including Mg-lime and pelletized Visnes Granulat), water treatment marble, abrasive blasting media (Marmor Soft, Jet, Plus), marble sand and chips for construction, asphalt filler, and eclogite armourstone, friction sand, and aggregates for offshore and infrastructure applications. Approximately 25-30 employees plus varying contractors run the quarry, processing plant, packaging lines, workshop, and two shipping quays, with the main ISPS-certified quay handling bulk loading at 2,500 tonnes/hour and ships up to 200 meters.

The company's go-to-market is direct B2B sales through quote-based custom pricing, with no public rate cards, supported by a multilingual corporate website and direct customer consultation. Distribution leverages owned export infrastructure plus partnerships with A.Visnes Transport for domestic trucking and Moldegaard Maritime Logistics for coastal delivery. End customers span seven verticals: agriculture, water utilities, construction, oil and gas, offshore wind, paper and glass process industry, and one-off heritage restoration (notably Notre Dame Cathedral). Sales reach Norway, broader Europe, and Asia. Visnes holds multiple regulatory approvals that materially expand its addressable market, including Norwegian Food Safety Authority registrations for drinking water, fertilizers, and feed (NO13051129), ISO 9001:2015 and 14001:2015, CE certifications under NS-EN 12620, 13043, and 13383, and Debios organic production registration. The company is in its fourth and fifth generation of Eide family management, with sister company Visnes Eklogitt AS handling the eclogite product line.
