Technical Specification Guide for Natural Stone

Good natural-stone specifications separate visual approval from performance requirements. This page is a buyer checklist—not a substitute for project engineer, architect, installer or laboratory advice.

Architectural drawings for natural stone specification

Visual range

Define acceptable color, veining, fossils, pores, resin, mesh, filling, repairs and bookmatch expectations using representative controls.

Dimensions

State nominal size, thickness, squareness, flatness and project tolerances. Do not assume every product type uses the same tolerance.

Performance tests

Request current, material-specific test data where relevant: absorption, density, flexural strength, abrasion, frost resistance, slip or anchor performance.

Exterior exposure

Consider climate, freeze-thaw, salts, pollution, moisture, thermal movement, anchoring system and façade engineering.

Wet areas

Coordinate finish, slip resistance, waterproofing, substrate, slope, grout/movement joints, sealing and cleaning chemistry.

Packaging & handling

Define crates or bundles, protective layers, labeling, moisture protection where needed, loading sequence and site storage.

RFQ checklist

Minimum useful specification

Stone trade names are not technical standards. Final selection should be tied to the actual material source, approved reference range and project-specific test reports.

  • Stone name / reference sample / desired color family
  • Application and interior/exterior exposure
  • Formats, thicknesses, quantities and drawings
  • Face finish and edge details
  • Selection grade or acceptable visual range
  • Required test standards or certificates
  • Packaging, labeling and delivery sequence
  • Destination and requested commercial term
Frequently asked

Questions buyers often ask

What information should I include in a technical inquiry?

Send the stone name or preferred color, required format and thickness, approximate quantity, finish, destination and timing. Drawings, schedules and reference samples are especially useful for cut-to-size projects.

Does Atlas own a quarry?

Atlas Global Trading Inc. operates as an independent sourcing and trading company. We coordinate supply with established quarry owners and processing factories in Turkey rather than limiting projects to a single quarry.

Can Atlas combine multiple Turkish stones in one project?

Yes. Multi-material schedules can be coordinated across compatible partner factories, with attention to samples, production timing, packing and shipment planning.

Can buyers request current slab or block photos?

Yes, subject to supplier availability. For natural stone, current-lot photos and representative samples are an important part of confirming color, vein movement and acceptable range before production.
