If you’re working with sloped land or want to prevent soil erosion, retaining wall installation is a smart solution.

Hobart’s mix of hilly terrain and unpredictable weather makes retaining walls a necessary structure for many homes and commercial sites. Besides preventing erosion, they allow you to reclaim usable space, improve drainage, and even add a decorative touch to your landscaping.

• Create usable, level areas on sloped properties.
• Prevent soil shifting and erosion.
• Manage surface water drainage
• Define garden beds or outdoor living zones.
• Support driveways or raised paths
  

Our retaining wall installation process ensures your wall performs well and fits seamlessly with your landscape.

One of the first steps is selecting the right building material. The choice will affect your wall’s appearance, strength, and durability. In Hobart, we commonly work with

• Timber sleepers—Affordable and quick to install, ideal for smaller garden walls
• Concrete blocks—strong, neat, and perfect for modern aesthetics
• Natural stone—Beautiful and durable, blending perfectly with Hobart’s environment
• Reinforced concrete—Best for high walls or structural support needs
  

We recommend materials based on the purpose of the wall, property slope, soil type, and your style preferences. Every retaining wall installation is unique, and our expert team will guide you through the best options.

At Headlam Howlett, we follow a structured process to ensure your wall is strong and built to last.

1. Site inspection and design planning
2. Clearing and excavating the area
3. Laying a solid gravel or crushed rock base
4. Placing materials in staggered, secure layers
5. Installing drainage systems behind the wall
6. Backfilling and compacting
7. Final touches and site cleanup
   

With years of excavation experience, we understand what it takes to get retaining wall installation right from the ground up.

Many retaining walls fail early due to poor drainage. Water buildup behind the wall adds pressure and can cause bulging, cracking, or collapse.

• Install drainage pipes (ag pipes).
• Use filter fabric to prevent soil movement.
• Layer gravel or scoria behind the wall.
  

These techniques ensure that your retaining wall installation is equipped to handle Hobart’s heavy rains and variable climate.

You may need council approval for some retaining walls, especially if they are

• Over 1 metre in height
• Near property boundaries
• Supporting a driveway or other structure
  

We help guide you through any required local permits, taking the stress out of the approval process. Our knowledge of Hobart's excavation and land requirements ensures everything complies with code.

While small garden walls can be DIY projects, larger or structural retaining walls need expert attention. Mistakes in excavation or drainage can be costly and even dangerous.

• Proper equipment for accurate excavation
• Experience with drainage and soil types
• Engineering and compliance support
• Guaranteed long-term performance
  

The cost of retaining wall installation depends on a few factors:

• Wall height and length
• Material type
• Site access and ground conditions
• Drainage and excavation needs
  

We provide honest, upfront quotes with no hidden costs. From small residential jobs to commercial projects, we offer competitive pricing and excellent workmanship.

• Choose the right material for your needs—not just the cheapest.
• Consider multiple wall tiers instead of one tall wall.
• Get it done right the first time to avoid future repairs.
