CEMMAC

What CEMMAC does

CEMMAC a.s. is a Slovak cement manufacturer founded in 1883 and headquartered in Horné Srnie, Slovakia, currently owned by Austrian construction materials group ASAMER Baustoff Holding Wien GmbH & Co. KG. The company operates a single integrated cement plant built around a 46-metre rotary kiln with 1,200 t/day clinker capacity, producing bagged and bulk cement in CEM I, CEM II (Portland-slag and Portland-limestone) and CEM III (blast furnace slag) grades in 32.5 and 42.5 strength classes, including a 2024-launched ecological limestone cement with 47% lower CO2 footprint than traditional Portland cement. Production is vertically integrated upstream through the company-owned Mojtín Quarry (acquired February 2018, 24 km from the plant) supplying limestone and crushed aggregate, and downstream through wholly-owned subsidiary CEMMAC Beton s.r.o. (established 2021) which operates seven concrete batching plants across Slovakia producing concrete mixes, self-levelling anhydrite screeds and concrete blocks; a TSÚS-certified Cement Kiln Dust (CKD) by-product was added as a marketable output in June 2025.

The business is sales-led, with dedicated regional commercial managers covering Northern/Northwestern/Central/Northeastern Slovakia plus Czech Republic and Poland, and Southern/Southwestern/Southeastern Slovakia plus Hungary, supported by an in-house logistics department and 7 own concrete plants for direct delivery. Customer segments include construction companies, concrete producers, large infrastructure contractors (notably the R2 Kriváň–Mýtna expressway, for which CEMMAC supplied ~73,000 tonnes of cement) and individual builders purchasing bagged cement. Sustainability is a strategic pillar: the company uses solid alternative fuels (TAP) for 65% of clinker-burning energy, is investing in a bypass reconstruction to reach up to 95% alternative fuel use, operates a 5 MWp photovoltaic plant on reclaimed quarry land covering ~7% of electricity needs, and has publicly committed to Net Zero by 2040. Pricing is quote-based through regional sales managers; the company holds ISO 9001 and ISO 14001 certifications and acts as General Partner of the Slovak Building of the Year competition.

Core offering

CEMMAC a.s. is a Slovak cement manufacturer that produces bagged and bulk cement (CEM I, CEM II, CEM III grades) at its plant in Horné Srnie, extracts natural crushed aggregate from its own Mojtín Quarry, and produces concrete mixes, anhydrite screeds, and concrete blocks through its wholly-owned subsidiary CEMMAC Beton s.r.o., which operates seven batching plants across Slovakia.

Product overview

CEMMAC is a cement manufacturer offering a unified portfolio centered on cement production with supporting raw material extraction and downstream concrete manufacturing. The core product line includes bagged cement (SUPER 425 R, PROFI 425 N, UNIVERSAL 325 R) and bulk cement spanning CEM I, CEM II (Portland-slag and Portland-composite types with limestone), and CEM III (blast furnace slag cement) classes in 32.5 and 42.5 strength grades. Raw material independence is secured through the Mojtín Quarry, which supplies natural crushed aggregate. Vertical integration is achieved via subsidiary CEMMAC Beton s.r.o., which operates 7 batching plants producing certified concrete mixes, anhydrite screeds, and concrete blocks using CEMMAC cement. The portfolio is rounded out by Cement Kiln Dust (CKD), a TSÚS-certified by-product of clinker production used in hydraulic road binders and cement admixtures.

Regional players

• Małogoszcz Cement Plant (Grupa Ożarów): Polish cement producer operating a single integrated cement plant, serving the Polish market with similar product portfolio (CEM I, CEM II) to CEMMAC. Comparable in scale and business model as a single-plant, domestically focused cement supplier in a neighboring CEE country.
• Wopfinger Baustoffindustrie: Austrian building materials manufacturer (part of the Baumit/Wopfinger group) producing cement, lime, and dry-mix mortars, primarily serving Austria and neighboring CEE markets. Comparable vertically integrated mid-sized producer with shared parent-group Austrian ownership heritage.

Broad incumbents

• Heidelberg Materials: Major German-headquartered cement and aggregates multinational with strong Central and Eastern European footprint (e.g., former Hranice plant in Czechia). Directly comparable to CEMMAC on cement product portfolio, ready-mix operations, and decarbonization roadmap.
• Holcim: One of the world's largest cement and aggregates producers with established operations in Central Europe. Competes with CEMMAC in Slovak and CEE ready-mix and bulk cement markets, and competes on low-carbon cement offerings (ECOPact, ECOPlanet) versus CEMMAC's ecological limestone cement.
• Cemex: Global cement, ready-mix, and aggregates producer with Central European operations. Comparable product mix and target customer base (ready-mix operators, infrastructure contractors) to CEMMAC across Slovakia, Czech Republic, Poland, and Hungary.
• CRH plc: Global building materials group with significant integrated cement, concrete, and aggregates operations across Central Europe (including Slovakia and the wider CEE region). Comparable to CEMMAC across the full cement-to-concrete value chain but at vastly greater scale and with cross-border logistics reach.

Others

• Wienerberger: Austrian-listed building materials leader focused on clay bricks, roof tiles, and pipe systems across CEE, and part of the broader Austrian construction materials ecosystem alongside CEMMAC's parent ASAMER. Not a direct cement competitor but adjacent in the CEE heavy-side building materials value chain.
• Geocycle (Holcim group): Provider of alternative fuel and waste-to-energy solutions for cement kilns, directly relevant to CEMMAC's 65% (rising to 95%) alternative fuel substitution program. Comparable as a partner/competitor in the decarbonization services that underpin CEMMAC's ecological cement positioning.

Direct peers

• Cementáreň Ladce: Slovak cement producer historically headquartered in Ladce, now part of a regional group, operating a single integrated cement plant in western Slovakia. The closest direct domestic competitor to CEMMAC a.s. with overlapping product range, customer base, and Slovak market geography.
• Buzzi Unicem: Italian-headquartered cement group with a major Central European cement footprint (including Poland via Dyckerhoff). Closely comparable regional cement peer competing for the same infrastructure and ready-mix customers as CEMMAC in overlapping CEE geographies.
