Retaining walls play a crucial role in landscaping, offering both functional benefits and visual appeal. They help stabilise slopes, prevent soil erosion, and create flat, usable spaces for gardens or other features. With adequate drainage they can all divert water away from a building structure, ensuring longevity. The following are some of the different type of retaining wall designs we offer at Walker Bartels:

1. Gravity Retaining Walls

• Mass Concrete

• Gabion

• Keystone

2. Cantilever Retaining Walls

• Reinforced Blockwork

• Reinforced Brickwork

• Reinforced Concrete

• Sleeper Retaining Walls

3. Sheet Pile Retaining Walls

4. Anchored Retaining Walls

Selecting the right retaining wall depends on factors like height, soil type, available space, design preferences and cost. Understanding the different types of retaining walls can help you choose a solution that not only serves its purpose but also enhances the beauty and functionality of your landscape.

A Regulation 126 Certificate of Compliance for proposed building work is generally requested by the Relevant Building Surveyor as part of the building permit process in Victoria. This certificate ensures that the design has been undertaken and/or reviewed by a registered, licenced and competent engineer, and that the design complies with the National Construction Code and the relevant Australian Standards.

A Form 15 Compliance Certificate for building design or specification is generally requested by the Building Certifier as part of the building permit process in Queensland. This certificate ensures that the design has been undertaken and/or reviewed by a registered, licenced and competent engineer, and that the design complies with the National Construction Code and the relevant Australian Standards.
