Different Types of Retaining Walls & Costs

Gravity Retaining Walls

Gravity retaining walls are a practical choice if looking to hold back soil without complicated construction.

Made from heavy materials like concrete, stone, or brick, these walls use their own weight to keep soil in place, making them especially suited for garden landscaping or smaller soil retention needs. It might be an option if you want a sturdy, low-maintenance solution.

• Materials: Concrete, stone, brick
• Typical Uses: Garden landscaping, small-scale retaining
• Cost: £150 - £300 per linear metre

Cantilevered Retaining Walls

Cantilevered retaining walls are a suitable choice for homeowners who need a strong and space-efficient solution to hold back soil. Made from reinforced concrete, these walls use a design that converts the pressure from the soil behind them into a downward force, keeping everything securely in place.

Ideal for larger gardens or properties with sloped terrain, cantilever walls are durable, can handle higher loads, and offer a space-saving alternative to bulkier wall types.

• Materials: Reinforced concrete
• Typical Uses: Large-scale commercial projects, property development
• Cost: £200 - £400 per linear metre

Anchored Retaining Walls

Anchored retaining walls are suitable for homeowners facing heavy soil loads or challenging slope conditions.

These walls use strong cables or stays driven deep into the soil or rock behind the wall to hold everything firmly in place. They are appropriate if your garden has steep slopes, or is tiered.

• Materials: Varies (cable, concrete, steel)
• Typical Uses: High-load retention, construction sites
• Cost: £250 - £500 per linear metre

If you are very unsure what wall will work in your garden, not only in terms of structural integrity but also in terms of looks, then you may need to hire a landscaper to help you plan. Take a look at this landscaping cost guide for more information.
