Yorkstone Grades & Re Grading Explained
Understanding Reclaimed Yorkstone Grades, Thickness Variation and How We Sort & Re Grade Stone Correctly
When working with reclaimed Yorkstone, grading is essential. Unlike new stone, reclaimed Yorkstone naturally varies in thickness, surface wear, colour and character.
Understanding these variations ā and managing them correctly ā is what separates a wellāsupplied project from a problematic one.
At Yorkstone Dealer, grading and reāgrading reclaimed Yorkstone is a core part of how we work. It allows us to supply stone that is fit for purpose, visually consistent and practical to install, whether for random paving, coursed paving, bespoke slabs or heritage projects.
What Are Yorkstone Grades?
Yorkstone grades are not about good or bad stone. They describe:
- Surface finish
- Level of wear
- Thickness range
- Visual character
Reclaimed Yorkstone has already lived a previous life, which is exactly what gives it its appeal. Grading ensures the stone selected is appropriate for its next use.
Common Types of Reclaimed Yorkstone Grades
Reclaimed Yorkstone is typically grouped into grades such as:
- Smooth / lightly weathered stone, often used for courtyards and higherāend landscapes
- Midāweathered stone, offering a balance of character and practicality
- Heavily weathered or rustic stone, ideal for traditional or period properties
Each grade has its place. The key is selecting the right grade for the project.
Thickness Variation in Reclaimed Yorkstone
Thickness variation is one of the defining characteristics of reclaimed Yorkstone.
Because reclaimed stone was historically handālaid, thickness will vary between slabs. Proper grading ensures:
- Compatible thickness ranges are grouped together
- Stone lays efficiently on site
- Finished levels are consistent
- Installation time is reduced
Thickness variation is not a problem when it is managed correctly at the supply stage.
Our Re Grading Process Explained
Reclaimed Yorkstone is not simply sold straight from uplift.
At our yard, each slab or flag is:
- Individually inspected
- Measured
- Assessed for thickness range and surface wear
- Grouped with compatible material
Where required, stone is reāgraded. This means:
- Moving slabs between stacks
- Refining sets for consistency
- Removing unsuitable pieces from specific orders
This process allows us to supply practical, workable stone sets rather than mixed, difficultātoālay pallets.
Coursed Paving and Thickness Management (Correctly Explained)
Coursed paving does not rely on perfectly uniform thickness.
Instead, coursed paving requires:
- Accurate control of course widths (for example 600mm, 450mm or 300mm wide)
- Careful sorting of thickness ranges within each course
- Logical grouping so courses lay consistently and finish level
Correct grading ensures each course works as intended, even with natural thickness variation.
Matching the Right Grade to the Right Application
Different projects require different grades and thickness ranges. For example:
- Coursed paving relies on accurate course widths and sensible thickness sorting
- Bespoke slabs and hearths require suitable face quality and structural integrity
- Heritage and period projects often benefit from heavier weathering
- Contemporary schemes may suit smoother, more uniform stone
Proper grading ensures the stone works with the design rather than against it.
Why Re Grading Makes a Real Difference on Site
Poorly graded reclaimed stone can cause:
- Installation delays
- Excessive bedding adjustments
- Inconsistent finished levels
- Wasted material
Professional grading and reāgrading:
- Speeds up installation
- Improves visual consistency
- Reduces labour costs
- Produces a better finished result
This is why grading is a critical part of supplying reclaimed Yorkstone properly.
Grading for Continuity and Future Matching
For larger or phased projects, grading also supports:
- Continuity across multiple deliveries
- Matching stone for future extensions
- Consistency between batches
By controlling grading at supply stage, we help avoid mismatched stone later on.
