The following proceedures ensure we maintain quality of product.

1. Quarrying and block selection
2. Splitting block with the bed to minimum bed height (this avoids splitting when fixed and frost penetration).
3. Finally prepare and guillotine stone to provide nominal bed width.
4. Select and hand finish individual stones to ensure rock face (no concave faces) and to ensure that stones are squared by pitching, this avoids twisted stones please note that "hammer dressing" does not achieve this).
5. Stack stone in 9ft x 2ft walls (called yarding up) to ensure correct measurement. (We convert stone sold by the square metre at point of sale). Again the stacking of the stone provides evidence of the quality of workmanship and should be closely considered.
