The right bedding sand, properly prepared and levelled, plays an important part in keeping your paving even and stable over time.
Another useful paving tip from the CMA and CMACS to help you get your paving project right from the start.
Paving Bedding Sand Layer
Once the supporting layer works have been correctly constructed and compacted, attention shifts to the bedding sand layer.
The bedding sand provides a uniform surface on which the concrete pavers are placed. It helps accommodate minor variations in paver thickness and assists with the correct seating and alignment of the paving units during installation and compaction.
The bedding material must be clean, suitable for purpose, and evenly graded. Unsuitable sand, excessive fines, contamination, or inconsistent material can affect drainage, compaction, and the long-term stability of the paved surface.
Bedding sand should be spread evenly over the prepared base and accurately screeded to the required level. It must form a consistent layer and should not be used to correct major irregularities, depressions, or level differences in the underlying base.
Only an area that can be paved within a reasonable period should be screeded. Once prepared, the bedding layer should remain undisturbed and must be protected from foot traffic, rain, contamination, and construction activity before the pavers are installed.
Care must also be taken not to overwork or prematurely compact the bedding sand before laying the pavers. Final seating occurs when the installed paving units are compacted into the bedding layer as part of the completed paving system.
A correctly prepared bedding sand layer contributes to an even finished surface, consistent support, effective load transfer, and the long-term performance of the concrete paving installation.
