Paver washout is loss or displacement of paving-related material associated with water flow; visible sand loss does not identify the full extent below the surface.
Surface loss versus concealed loss
CMHA recommends maintaining joints and observing pavement performance. Water-related loss can appear in joints or at edges, while underlying conditions may not be visible. Do not assume a small sand trail proves complete base removal or a specific drainage defect. See CMHA operation and maintenance of interlocking concrete pavement.
Follow the observed water route
Record where water enters the paved area, crosses joints and leaves the edge. Downspout discharge, concentrated roof runoff and surrounding slopes may be relevant if observed. Photographs during rain from a safe place can support the assessment.
Refill does not reroute runoff
Adding compatible joint material may form part of maintenance, but does not redirect concentrated water or restore lost support. Discuss the water path and edge restraint when loss recurs. Sealer is not a universal cure for erosion beneath paving.
Coordinate paving and drainage decisions
Ask whether the pavement repair and runoff change need to be planned together. Moving discharge without checking its new receiving area may relocate the concern. Avoid assuming the correct solution is always a larger gutter or another buried pipe.
Planning the next step
Identify whether the pavement carries pedestrians, vehicles or poolside traffic and provide photos of the full area, not just one joint. Mention previous repairs, known coatings and where runoff travels. Ask which observations support the proposed treatment and whether supporting layers need assessment. This guide concerns conventional concrete pavers unless a different system is specifically identified; natural stone, mortared and permeable assemblies require their own guidance.

Frequently asked questions
Does visible sand prove the whole base washed away?
No. The depth and extent need assessment.
Will sealer fix lost support beneath units?
No. Surface treatments do not restore supporting layers.
Should the runoff path be checked with the paving?
Yes. Recurring material loss warrants evaluating observed water flow.
