This standard covers the design and construction practices for ashlar stone masonry. It provides guidelines on material selection, precise stone dressing, mortar preparation, laying techniques, and curing required to achieve high-quality structural and architectural stone walls.
Code of practice for construction of stone masonry, Part 2: Ashlar masonry
Quick Reference Values
max joint thickness fine ashlar3 mm
max joint thickness rough tooled ashlar6 mm
max construction height per day1.5 m
minimum curing period7 days
bond stone frequency1 per 0.5 sq.m of wall face
Practical Notes
Ensure stones are thoroughly wetted before laying to prevent them from absorbing moisture from the mortar.
Joint thickness in fine ashlar should strictly be kept minimal (max 3 mm) for structural integrity and premium aesthetic finish.
Always provide proper through stones (bond stones) at specified intervals to structurally tie the inner and outer faces of the wall together.
