Logistics & Installation Support
In-house sawing lines convert blocks to slabs in controlled dimensions. Calibration, polishing, and surface finishing are executed to project specification before dispatch.
SPI-owned quarries in Italy, Portugal, and Spain. We select, extract, and grade blocks at source — no third-party procurement, full geological traceability.
SPI coordinates international freight, customs, and site-delivery scheduling. Installation advisory is provided on complex architectural assemblies.
Fabricated from the stone we extracted
Columns, capitals, carved panels, bespoke sinks, and full cladding systems are CNC-produced in our own facilities from SPI-extracted blocks — ensuring vein continuity and color consistency across every element.
Project-specific sourcing means we match vein patterns across phases and hold material for contractor schedules. No inventory speculation — every block is allocated to a project.
