Stonework
Retaining walls & stonework
A retaining wall that leans or bows was never built right. Since 1995, Karmi Landscaping has engineered walls across the GTA, Peel, Durham, Niagara and surrounding areas — proper base, proper drainage, proper backfill — so they hold grade for decades, not seasons.
What we build
- Segmental block and natural stone retaining walls
- Steps, terracing and grade changes
- Drainage and grading behind the wall
- Garden and seat walls
- Repairs and rebuilding of failed walls
How we work
We excavate to a stable base, compact the footing, lay the first course level, and build with drainage and backfill behind the wall so water never builds up against it. You get a written scope before we start and a walkthrough when we finish.
