What Calcidrata does

Calcidrata is a Portuguese, family-owned industrial producer of lime and limestone products founded in 1981, with multi-generational heritage in the lime industry dating back to 1900. The company is vertically integrated, operating its own limestone quarries in Alcanede, vertical continuous kilns for calcination, automated hydration and packaging lines, and a wholly-owned logistics subsidiary (Transcálcio) for direct distribution. Its product portfolio spans quicklime (Cal Viva), hydrated lime (Cal Hidratada), lime paste (Cal em Pasta), the INTOMIX line of mortars and renderings, Cimento-Cola tile adhesives, and the Agrisolo agricultural lime brand, sold in multiple formats (bags, big-bags, bulk).

The company serves twelve distinct verticals including construction and public works, agriculture and animal production, sugar processing, water treatment, chemical industry, mining, environmental services, pulp and paper, paints and coatings, steel and metallurgy, and glass and ceramics. Production is differentiated by 100% biomass fuel (from industrial waste) for calcination, every-batch laboratory quality testing, and certifications including ISO 9001 (first in Portugal's lime sector, 2002), ISO 14001, CE Marking, and REACH compliance.

Calcidrata operates a sales-led B2B go-to-market with quote-based pricing, serving enterprise customers through direct sales and own-fleet delivery exclusively within Portugal. The company is recognized as a national leader in the Portuguese lime and limestone market, with no disclosed international operations, no public listing, no external institutional investors, and no revenue figures disclosed in available sources.

Core offering

Calcidrata extracts limestone from its own quarries in Alcanede, Portugal, and manufactures lime products (quicklime, hydrated lime, lime paste), industrial mortars and renderings (INTOMIX brand), tile adhesives (cimento-cola), agricultural lime (Agrisolo), and ornamental stone blocks. Products are sold in multiple formats (bags, big-bags, bulk) directly to construction, industrial, and agricultural customers across Portugal via its own logistics subsidiary.

Product overview

Calcidrata offers a diversified portfolio of lime and limestone products for construction, agriculture, and industrial applications. The core product line includes Cal Viva (quicklime), Cal Hidratada (hydrated lime), and Cal em Pasta (lime paste) — each available in multiple formats. Building materials are sold under the INTOMIX brand for mortars and renderings (including hydrophobic variants), and as separate Cimento-Cola (tile adhesive) products in white and gray. Agricultural products are sold under the Agrisolo brand. The company extracts limestone from its own quarry in Alcanede and processes it through calcination to produce various lime derivatives. The product architecture follows a unified portfolio approach: lime-based raw materials (quicklime, hydrated lime, paste) serve as foundation inputs, which are then transformed into processed building products (mortars, renderings, tile adhesives) and agricultural products.
