Edge restraint helps keep a paver field from spreading at its perimeter.

How to plan it
- Measure exposed outer edges separately from edges against fixed structures
- Choose a restraint compatible with the paver system
- Include anchors and curves in the supplier quote
Check before buying: A perimeter length is different from the patio area.
