At NYN Engineering, we provide comprehensive structural design services for retaining walls of all types — from small residential boundary walls to large engineered systems supporting significant loads. Our design strategy centres on achieving long-term performance through a balance of strength, serviceability, and economy.
Each design is carefully developed to reflect the unique characteristics of the site, including soil profile, drainage behavior, surcharge effects, and groundwater conditions. We prepare detailed engineering drawings and documentation in accordance with Australian Standards and the specific requirements of local councils.
By combining sound engineering principles with practical construction awareness, we deliver retaining wall solutions that are structurally efficient, safe, and built to last.
Major types of Retaining Walls, We Design:
- Block Retaining Walls – modular interlocking systems, ideal for landscaping as well as light residential and commercial applications.
- Reinforced Concrete Cantilever Retaining Walls – economical solution for medium to large heights, designed to efficiently resist soil pressures through a cantilever action.
- Concrete Sleeper Retaining Walls – precast reinforced concrete sleepers supported by steel posts, commonly used in residential and commercial sites.
- Timber Sleeper Retaining Walls – cost-effective option using treated timber sleepers, suitable for light-duty applications.
- Shotcrete Retaining Walls – sprayed concrete walls reinforced with mesh and/or soil nails.
- Crib Retaining Walls – interlocking concrete units filled with granular material, providing flexibility and effective load distribution.
- Gravity Stone Retaining Walls – Stone walls that rely on self-weight to resist earth pressure.
- Dincel System Retaining Walls – permanent polymer formwork system, reinforced with concrete for strength and durability.
