Guber Natursteine Ag

What Guber Natursteine Ag does

Guber Natursteine AG is a Swiss natural-stone producer that extracts and processes Guber Quarzsandstein (quartz sandstone) from a single quarry above Alpnach in the Canton of Obwalden. The current Aktiengesellschaft was re-founded in 1987 by private shareholders after the original 1903 operation (founded by Giovanni Toneatti and Jacques Hösli) and its successor under Stuag ceased production in 1986; the company is now managed by the second generation of the founding family.

The product portfolio is organized around two surface technologies — split-face (gespaltener) hand-crafted stone and diamond-cut (gefräster) precision-machined stone — yielding pavers, binder stones, wild pavers, masonry stones, flooring slabs, stair steps, coping stones, channel drains, cladding, cyclopean masonry, and stepping stones. The registered Guber Moderna® sub-brand targets barrier-free construction with tight dimensional tolerances. Processing combines traditional hand craftsmanship with CNC-controlled diamond cutting and surface flaming, powered by solar energy and Swiss hydropower. The company holds ISO 9001 (SQS) and CE certifications, and the quarry carries the Nature & Wirtschaft 'Nature & Park' quality label (recertified 22.06.2022); products are certified to SIA norms 246, 248, 226 and SN standards.

Revenue is generated through one-time, unit-priced sales (per ton, per m², per piece) of natural stone products ex-works in CHF, with surcharges for sub-minimum orders and storage fees on uncollected reservations. Distribution is direct: customers collect from the quarry or order via a website contact form and inside sales team led by a sales manager and key account manager. Customers are primarily Swiss — architects, builders, landscape designers, and government public-works departments (Canton of Basel-Stadt, municipalities of Zurich, Basel, Fribourg) — with documented repeat projects across Switzerland and episodic project-level work in Germany. There are no subsidiaries, no public listing, and no disclosed funding history; operations are anchored at the Alpnach quarry and the Kägiswil business office.

Recent moves10 records

Expansion highlights5 records

Regional players

• Franken-Schotter GmbH & Co. KG: German family-run natural stone quarry and processing company producing Jura limestone for paving, masonry, and landscaping. Comparable in size, family ownership model, traditional-craft-plus-modern-machinery approach, and DACH-region B2B sales.
• Jura-Steinwerke GmbH: German limestone/dolomite aggregate and dimension stone producer. Adjacent in material category (calcium-silicate stone) with overlapping construction and paving customers in the DACH region; serves as a regional competitor for cross-border Swiss-German projects.
• Laaser Marmor GmbH: Italian (South Tyrol) marble quarry and fabrication company with deep heritage, supplying cut stone for architecture and public works across Europe. Comparable in business model (heritage quarry + CNC cutting + B2B architectural sales) and competes for premium Swiss architectural projects.

Direct peers

• Andeer Granit AG: Swiss natural stone quarry and processor in Graubünden extracting and selling Andeer granite for similar paving, masonry, and architectural applications. Closest direct domestic peer — same Swiss market, same B2B sales motion, same dimension-stone product categories.
• Solnhofen Stone Group: German natural stone quarrier and fabricator specializing in Solnhofen limestone and Jura marble slabs/tiles for architectural and landscaping use. Direct comparable in product (cut natural stone for construction), process (quarrying + finishing), and customer base (architects, builders, public works).
• Valser Quartzit / Valser Sandstein: Swiss operator of historical quartzite/sandstone quarries in Graubünden offering similar natural stone products for paving and facade use. Direct competitor for heritage Swiss architectural projects with comparable single-quarry, single-material proposition.

Broad incumbents

• Holcim (Schweiz) AG: Swiss subsidiary of global building materials giant Holcim, producing aggregates, concrete, and cement. Competes indirectly on paving and infrastructure tenders where concrete substitutes natural stone; relevant as the dominant Swiss incumbent bidding against Guber in public works.
• Heidelberg Materials AG: Major European building materials producer with aggregate, cement, and concrete operations across Switzerland and DACH. Broad incumbent competing for the same infrastructure budgets, often substituting natural stone with concrete solutions.
• Vulcan Materials Company: Largest US producer of construction aggregates (granite, limestone, sand & gravel). Provides a useful comparable for the unit economics and cyclicality of quarry-based natural stone businesses, though at vastly larger scale.

Emerging players

• Stone Group International (Stone Italiana): Italian engineered/quartz stone manufacturer. Not a direct quarry competitor but increasingly relevant as an alternative specification when architects choose engineered surfaces over natural stone — represents the substitution threat to Guber's premium positioning.
