Define the visible and measurable details
“Bluestone” alone is not a complete specification. Record the intended dimensions, thickness, edge detail, surface finish and the range of natural variation that is acceptable. Ask whether supplied images are illustrative and how the current batch compares with the sample.
For paving and other exposed applications, discuss the expected environment with the designer and installer. The right finish and construction system depend on the project, so avoid copying a detail from a photograph without checking its suitability.
Document what happens before installation
Confirm ordering quantities, delivery arrangements, inspection, storage and who approves variation. Agree whether any sealant, cleaning product or maintenance procedure is recommended by the relevant product manufacturer, and ensure the installer is working from the same information.
- Product and source reference.
- Dimensions, thickness and edge profile.
- Surface finish and intended application.
- Approved sample and acceptable natural variation.
- Delivery, storage, installation and maintenance responsibilities.
Common questions
Does natural variation mean a batch is faulty?
Natural stone can vary in colour and character. The important step is agreeing the expected range and approval process before supply and installation.
Can one bluestone finish be recommended everywhere?
No. Application, exposure and project requirements differ. Ask the designer, supplier and installer to confirm the exact proposed system.
