Extraction to Installation
Holding company headquarters. All contracts, compliance, and strategic procurement are managed from the Swiss entity.
Owned quarries and production facilities operating across three countries, each with direct extraction rights and on-site processing capability.
Every step — block extraction, slab processing, CNC fabrication, logistics, and project delivery — is executed within the SPI supply chain.
No intermediaries between geology and your project.
Architects and project directors specify stone knowing that SPI holds the extraction license for that block. Provenance is documented, not claimed. Consistency across project phases is guaranteed by the same entity that cut the block.
From first specification to final installation, one point of contact. No reseller markups, no provenance gaps, no substitution risk mid-project.
