Brick Path Edging and Joint Options for Informal Walkways

Building a Durable Brick Path

Replacing grass with brick requires proper edging and joint treatment to prevent shifting and weed growth.

Edging: Plastic vs. Steel/Paver Restraints

Standard plastic garden edging lacks rigidity to maintain straight lines under traffic and freeze-thaw cycles. Use steel edging or heavy-duty paver restraints (search "paver edging") designed to lock pavers in place.

Joint Width and Sand Choice

Wide joints allow movement over time. For stability:

• Keep joints tight (⅛–¼ inch) for a formal look.
• Use polymeric sand—it hardens when activated with water, resisting weeds, ants, and erosion.
• For a rustic look with wider gaps, polymeric sand still works but requires deeper joints.

Installation Tips

1. Excavate 6-8 inches; compact subgrade.
2. Add 4 inches crushed stone base; compact thoroughly.
3. 1 inch coarse sand setting bed; screed level.
4. Lay bricks; install edging before final compaction.
5. Sweep polymeric sand into joints; mist per manufacturer instructions.

Proper edging and polymeric sand ensure a beautiful, low-maintenance path for decades.
