MASONRY WALLS, SEAT WALLS, retaining walls – RECOMMENDATIONS

MENUMENU

Walls are used both free standing and in retaining conditions throughout the trail system.

While each wall or wall system will have unique characteristics and manufacturer’s recommendations for installation, it is important that key elements be considered for any wall:

  • Wall cladding and cap should be elevated above surrounding soil by a minimum of 1”.
  • Waterproofing should be included at the lowest wall courses.
  • Stainless steel wall ties should be used.
  • Wall caps should have adequate drip edges.
  • Care should be taken when selecting base courses to be used adjacent to pavements where de-icing salts will be used.
  • Where handrails are required at the top of walls, they should be incorporated into the wall design, and not have their own separate footing behind the wall.
  • Avoid trapping water, consider drainage behind walls including foundation drainage.
  • Walls provide good opportunities for environmental graphics and/ or signage as part of greenway branding.

Freestanding and retaining walls can provide architectural points of interest and seating options at various points along a trail. Seatwalls (right image) are recommended to be installed at a comfortable sitting height, 14-20”.
