BS 7533 — Pavement & Paving Construction
BS 7533 — Pavements constructed with clay, natural stone or concrete pavers
In short: BS 7533 is the British Standard series governing the design and construction of paving — covering bedding, jointing, laying course depth and minimum falls for clay, stone and concrete pavers.
What BS 7533 covers
The series sets out how paving should be built to perform structurally and drain correctly, rather than how much material you need.
It specifies a full wet mortar bed for slabs (not dot-and-dab) and a minimum fall of 1:60 to shed surface water away from structures.
The series was restructured in recent editions: the older part numbers (e.g. BS 7533-13) have been superseded by the BS 7533-101/102/103 structure.
