Retaining Walls

---

Retaining walls rely on their weight for their stability. Most embedded walls use passive earth pressures within the ground to provide resistance. In-order to design or check the capacity of the retaining wall, the soil and groundwater conditions, height of the wall and the suitable fill material should be considered. Retaining Wall Designs are essential to the protection of structures from damage relating to soil collapse. A retaining wall is an erected structure, constructed or placed after excavation of soil to provide support to the ground, preventing soil erosion or collapsing. We have participated in Projects consisting of: 

1. Project Management​
2. Inspections & Certification​
3. Conceptual Designs
4. Investigation & Reports
5. Loading and material factor analysis for Load Combinations as per AS 4678
6. Serviceability design including analysis for  failure modes:​ Bearing ,Sliding ,Overturning
7. Structural Ultimate limit state design for:

• Reinforced concrete block
• Sandstone block, cantilever 
•  Earth and gabion retaining walls​ ​

​In addition to Engineering Design Consultancy services, we also offer an extensive service in planning such as preparation of documentation for Permission to Lodge, Development Applications and Review of Environmental Factors, Contract Administration, Site Investigation and Design Reports and certification.
