Definition and homeowner use
The prepared sand layer immediately beneath sand-set interlocking concrete pavers, distinct from the base and joint sand. This definition helps separate a material or surface condition from the broader installation, repair or maintenance service that may be needed.
Bedding, base and joints are different
Bedding sand supports the pavers immediately below their faces. The compacted base lies beneath it, while joint sand occupies the gaps between pavers. These materials serve different roles and are not interchangeable.
Material selection affects performance
CMHA explains that bedding sand contributes to installation, interlock and drainage in sand-set concrete pavement. Its guidance is application-specific, particularly for vehicular use; not every bag labeled sand is suitable bedding material.
Installation limits
Bedding should follow the project’s pavement design and material guidance. It is not a substitute for an adequately prepared base and should not be used as an arbitrary thick fill to hide base irregularities.
Diagnosing a low area
Surface settlement alone does not prove a bedding-sand defect. The base, water path, edge restraint and prior construction can all require evaluation before a repair is specified.
Requesting an assessment
Provide photos of the full area and close views of the observed condition. Mention drainage patterns, previous repairs and known cleaning or sealing products. Ask for the proposed treatment and its limits in writing; a photograph alone does not establish the underlying cause.

Frequently asked questions
Is bedding sand the same as polymeric joint sand?
No. Bedding is below the pavers; joint sand fills spaces between them.
Can extra bedding replace proper base preparation?
No. Follow the pavement design rather than hiding base deficiencies with additional sand.
Does every paver system use sand bedding?
No. This guide concerns sand-set interlocking concrete pavement, not every possible paving assembly.
