Ever thought about building a retaining wall yourself? On paper, it looks simple — stack some blocks, add a little gravel, call it a day. But in reality, building a strong, level, and long-lasting wall is one of the trickiest landscaping projects out there. Let’s break down what it really takes to do it right.
1. Start With the Right Plan (and Permits)
Before you even touch a shovel, you’ll need:
- A solid design plan that accounts for slope, drainage, and load pressure.
- Local permits if the wall exceeds a certain height (usually 3–4 feet).
- A clear understanding of soil type and water flow on your property.
Miss one of these steps and your wall might not last past the next heavy rain.
2. Choose the Correct Materials
Retaining walls can be made of:
- Concrete blocks
- Natural stone
- Pressure-treated timber
- Poured concrete
Each material comes with its own installation quirks, costs, and long-term maintenance needs. Using the wrong one for your soil or slope can cause cracking, bulging, or collapse over time.
3. Dig Deep — Literally
A good retaining wall starts with a proper base trench filled with compacted gravel.
It needs to be:
- Level to within fractions of an inch.
- Deep enough to support the full wall height.
- Compacted layer by layer (not just dumped in).
Getting this wrong is the number-one reason DIY walls fail.
4. Drainage Is Everything
Without proper drainage, water builds up behind the wall and creates pressure that can push it forward or knock it down.
That’s why pros always install:
- Drainage pipes (weeping tiles).
- Gravel backfill.
- Geotextile fabric to prevent clogs.
It’s not the flashiest part of the job — but it’s the one that keeps the wall standing.
5. The Final Details Matter
From staggering joints to adding caps and compacting soil behind each layer, every small detail affects how well your wall performs over the years.
It’s a workout, it’s precision work, and it’s not something you want to redo twice.
🏡 The Real Takeaway:
Sure, you could spend your weekend moving hundreds of pounds of stone, checking levels every inch, and Googling drainage diagrams.
Or — you could enjoy your weekend while our Sunrise Landscape & Design crew handles the heavy lifting (and the permits, and the drainage, and the design).
Your wall will look perfect, last for decades, and you’ll still be able to move on Monday.
