How we build a retaining wall
Most walls that fail do it because water builds up behind them. Here’s what goes into a block wall, from the base up.
- Compacted gravel base Dug below grade, filled with crushed gravel and compacted so the wall can’t settle.
- First course buried The bottom row of blocks sits below the lower yard’s grade to lock the wall in place.
- Blocks set back Each row steps back slightly into the slope, so the wall leans into the soil it holds.
- Cap blocks Glued down on top to finish the wall and tie the last row together.
- Clear drain rock Washed rock behind the wall lets water drain down instead of building up pressure.
- Perforated drain pipe Runs along the bottom behind the wall and carries the water away.
- Filter fabric Keeps soil from washing into the drain rock and clogging it.
- Geogrid on taller walls Mesh layers laid between rows and run back into the slope to anchor the wall.
- Topsoil and sod The slope behind the wall is finished with soil and lawn or planting.

What clients say
★★★★★
Hard Hat Holligans were exceptional! I called them to replace the garden bed at my home, and they came out the very next day. They did an outstanding job from start to finish. They were professional, reliable, and offered very fair pricing.

Retaining wall questions
Do I need a permit for a retaining wall?
Often, for taller walls. Many Lower Mainland cities need a permit and an engineer’s design once a wall passes a set height, commonly about 1.2 m (4 ft). Check with your city, or tell us the height when you text.
Block or timber?
Block walls last longer and handle taller heights. Timber costs less and suits low walls, steps and garden beds.
What stops a retaining wall from failing?
Drainage. Water building up behind a wall pushes it over. We build on a compacted base with clear gravel and perforated drain pipe behind the wall so the water can get out.
Do you build raised garden beds?
Yes, in timber or metal, sized to fit the space and filled with soil ready to plant.
