ELF Bespoke Precast Retaining Walls
Built for higher loads, longer lifespans, and more demanding environments.
Flexible retaining wall systems designed to meet your specification
Our ELF precast retaining walls are fully customised – designed and manufactured to meet the specific demands of each project.
Whether you’re dealing with higher surcharge loads, increased durability requirements, or extended design life targets of up to 120 years, ELF offers the engineering flexibility to provide the right solution without compromise.
These bespoke retaining walls are perfect for infrastructure, waste storage, and high-end civil engineering projects where standard precast walls can’t meet the required specifications.
Key Product Benefits
Designed to your specifications – surcharge, exposure class, thickness, and height all tailored to your project.
Built for tougher conditions – from coastal and flood-prone sites to aggressive chemical or chloride environments.
Increased fire resistance – up to 120 minutes separation for combustible material storage (subject to specification).
Design lifespan up to 120 years – with increased cover to reinforcement and improved durability.
Cast-to-order precision – no compromises on height, thickness, or finish.
Ideal for high-spec retaining wall applications
Our ELF wall system is designed for projects where strength, durability, and lifespan are critical.
Each precast unit is produced to order and specially designed to perform – whether you’re retaining earth, protecting coastal zones, or handling bulk material storage.

If your project requires taller units, a longer design life, or has more demanding environmental conditions, we can modify the ELF retaining wall design to meet your specific needs.
We’ll work with you to develop a structural design that matches your ground conditions, load requirements, and compliance standards.
| Wall System | Surcharge Capacity | Max. Height | With Heel | Interlocking | Fire Resistance | Design Life |
|---|---|---|---|---|---|---|
| CLF10GS | 10 kN/m2 | 4.5m | No | Yes | 30 Minutes | 50 Years |
| CLF10GS(Z) | 10 kN/m2 | 4.5m | Yes | Yes | 30 Minutes | 50 Years |
| DLF10GS | 25 kN/m2 | 4.5m | No | Yes | 30 Minutes | 50 Years |
| DLF10GS(Z) | 25 kN/m2 | 4.5m | Yes | Yes | 30 Minutes | 50 Years |
| ELF | Custom | 6m | No | No | 120 Minutes | >120 Years |
We had just under 800 metres of retaining walls delivered to site within a short period. The quality of the units is excellent, with a very consistent finish. A job well done in tight time constraints.
