Independent natural stone inspections

The material approved for the project must remain identifiable throughout the supply process. We support clients, designers and contractors in stone selection and technical checks, from quarry to construction site.

Inspection stages
01 · SELECTION

Samples and specifications

Definition of reference samples and comparison criteria: appearance, finish, dimensions and performance required by the project.

02 · QUARRY

Material selection

Checks on blocks and the visible characteristics of the stone, with particular attention to the variability of material intended for the project.

03 · PROCESSING

Checks at the processing plant

Comparison of slabs and finished elements against approved samples and specifications: appearance, finish, dimensions and piece identification.

04 · SUPPLY

Before delivery

Checks on batches, markings and supply documentation. Any discrepancies are recorded with photographs and technical observations.

05 · CONSTRUCTION SITE

Delivered material

Checks on whether the delivered material corresponds to the approved material and project requirements; technical assessment of identified issues.

06 · LABORATORY

Testing when needed

Visual checks can be supplemented by physical and mechanical tests selected according to the material and its application.

Documented findings at every stage

The inspection programme is agreed with the client before the assignment begins: inspection points, acceptance criteria and reporting arrangements.
