How to Choose Retaining Wall Block
Start with wall height and what the wall is holding back. Low garden walls can use lightweight units, while taller walls or walls with surcharge loads need an engineered segmental system, geogrid reinforcement and often a design professional.
Key factors:
- Height and loading: driveways, slopes and structures above a wall change the design entirely.
- Setback and batter: different units lean back at different rates, which affects appearance and capacity.
- Drainage: drainage stone and pipe behind the wall matter as much as the block.
- Base: a compacted, level base course determines whether the wall stays straight.
- Finish: cap options, corners and steps should be planned before ordering.
Bring elevations and site photos to East Coast Landscape Supply and we can help match a wall system to the job — (603) 506-6300. Walls above the manufacturer's unreinforced height limit should be reviewed by an engineer.
