Calbrita

What Calbrita does

Calbrita – Sociedade de Britas, S.A. is a privately held Portuguese extractives company that produces and commercializes limestone aggregates for the civil construction sector. The firm was founded in 1980 (with predecessor activity dating to 1966) and is headquartered in Alenquer, Portugal, operating two industrial limestone quarries: Pedreira Casal Viegas n.º 2 in Carapinha (operating since 1980) and Pedreira do Calcário in Moita (operating since 1960). The combined annual production capacity is approximately 4,000,000 tonnes, and the company maintains an in-house quality laboratory that issues CE-marked Declarações de Desempenho for each product line.

The product portfolio spans the full granulometric range — powders (0/4 mm), "bago de arroz" (2/5, 4/6 mm), crushed stone grades Brita 1 through Brita 5 (4–63 mm), tout-venant (unwashed aggregate, 0/22 and 0/32 mm), enrocamento (rock fill, 45/250 mm), and river sand — alongside calcium carbonate fillers (SCA 10/20/30) produced by the wholly-owned subsidiary Sicalpor, Lda. Distribution to construction companies and civil engineering projects is handled in-house through another wholly-owned subsidiary, Calbrita Transportes, Lda.

Calbrita operates a sales-led B2B go-to-market with quote-based pricing (no public tariffs) targeting the Portuguese civil construction vertical. The firm employs approximately 60 people, is structured as a Sociedade Anónima with no public listing, and shows no institutional investment, PE, or VC backing in the available sources. Revenue is generated primarily through one-time sale of aggregates and fillers to construction buyers, with the integrated quarry-to-haulage model supporting delivered-cost competitiveness within the Iberian market.
