Kies- & Betonwerk Frei Ag

What Kies- & Betonwerk Frei Ag does

Kies- & Betonwerk Frei AG is a Swiss construction-materials supplier operating in the Zürcher Weinland region of Canton Zurich. Founded in the 1940s by the Frei family and incorporated in 1991, the company is a wholly-owned subsidiary of Toggenburger AG (Winterthur), acquired in 2012 as part of a structured family succession arrangement. With approximately 25 employees, Frei runs an integrated materials lifecycle business spanning gravel extraction and processing, ready-mix concrete production (computer-controlled plant at Kleinandelfingen inaugurated in 2010), transport and crane services (in partnership with Trelag AG), demolition and earthworks, recycling of construction demolition materials into SN-standard aggregates at the company's Marthalen facility (achieving up to 90% material recovery), and specialized disposal of excavation material, sludge, and invasive neophyte species.

The company's product portfolio includes graded gravel fractions (4/8mm to 16/32mm and beyond), sand, crushed stone (Splitt), recycled RC-Kiesgemisch B 0/45, colored concrete (for architectural applications such as the Herrenacker public square in Schaffhausen), and the recently added MISAPOR Schaumglasschotter sustainable insulation product. Quality assurance is provided through the parent's SAS-accredited construction materials laboratory (STS 0565, accredited since 2011). Mechanized assets include a modern concrete batching plant with computer-controlled systems, a Gipo GS 144/2 screening plant installed in 2022, and a sludge press rebuilt in 2020 that recycles wash water back into production.

The business model is sales-led and project-driven B2B, with regional direct sales targeting construction companies, municipalities, and public-sector clients in Zürcher Weinland and adjacent areas. Pricing is unit-based (per ton for aggregates, per cubic meter for concrete) with project-specific quotations and a partner portal for pricing and document access. Revenue streams include one-time materials sales, transport transaction fees, recycling and disposal fees, and professional services for demolition and earthworks. Named enterprise customers include Implenia Schweiz (Cholfirst safety tunnel, 2020–2024), ARGE Landolt/Bolli/Gasser (Breiti Park Schaffhausen), Specogna Bau, Walo Bertschinger, and the GWG housing cooperative, alongside a long tail of regional builders and private pickup customers served from the Kleinandelfingen site.

Expansion highlights4 records

Broad incumbents

• Holcim (Schweiz) AG: The Swiss arm of global cement and aggregate leader Holcim Group, producing cement, ready-mix concrete, and aggregates nationally. Overlaps directly with Frei AG on concrete and aggregate supply in Zürcher Weinland as a much larger incumbent with broader product and geographic footprint.
• Implenia AG: Switzerland's largest construction and real estate services company, with own materials operations and a leading customer of Frei AG (Cholfirst tunnel project). A broad incumbent combining contractor scale with internal Kies/Beton capabilities that competes for integrated project packages.
• Toggenburger AG: Winterthur-based parent company (since 2012) operating Kies, Beton, Transporte, and disposal businesses across a broader geography in Switzerland. Operates sister operations to Frei AG in adjacent regions with overlapping offerings, sharing laboratory and disposal infrastructure.

Direct peers

• Walo Bertschinger AG: Major Swiss construction group with own Kies/Beton supply operations in addition to civil engineering contracting. Heavy construction customer of Frei AG (e.g., Rheinbrücke Flaach project) that also self-supplies, making it both customer and partial competitor in regional aggregates.
• Eberhard Unternehmungen AG: Swiss family-owned construction group with integrated Kies/Beton, Recycling, Rückbau, and Erdbau capabilities. Closely matches Frei AG's regional integrated-service model and historical family-owned construction materials lineage.
• Fanger Kies + Beton AG: Swiss regional operator with Kies, Beton, and Recycling plants serving local construction markets. Closely comparable mid-sized integrated aggregate and concrete producer with similar end-customer mix.
• KIBAG AG: One of Switzerland's largest construction materials groups operating Kies, Beton, Recycling, and Erd-/Rückbau divisions across multiple regions. Directly comparable integrated portfolio, regional operating model, and customer segments - the principal Swiss independent peer to Kies- & Betonwerk Frei AG.

Others

• Misapor AG: Swiss producer of foam glass gravel (Schaumglasschotter), a sustainable insulation aggregate that Frei AG has just begun distributing in loose bulk at Kleinandelfingen (March 2026). Acts as upstream product partner/supplier rather than direct competitor.

Regional players

• GU Kies AG: Small Beringen-based aggregate and disposal operator specifically named in Frei AG's data as a co-investment disposal partnership. Comparable regional Swiss Kies/Ablagerungen operator serving overlapping northern Swiss/Zürcher market territories.
