What is a Retaining Wall?

A retaining wall is a structure built to support and hold back soil or rock from an area or structure. These walls can be used to create usable outdoor space, stabilize slopes, and prevent erosion. They are often constructed when there is a desired change in ground elevation that exceeds the natural angle of repose of the soil.

Cantilever retaining walls are a common type of retaining wall that are freestanding structures without lateral support at their tops. They are supported by a footing and rise above the grade on one side to retain a higher level grade on the other side. These walls must be able to withstand lateral pressures from loose soils or water.

Proper design and installation of retaining walls is crucial in order to properly support the retained material and prevent it from moving downhill due to gravity. This creates lateral earth pressure on the wall, which depends on the angle of internal friction and the cohesive strength of the retained material, as well as the movement of the retaining structure.

At Retaining Wall Supplies, we offer the materials you need from steel sleeper posts to concrete sleepers as well as design services for retaining walls of all sizes and for a variety of uses. Our team of experts is dedicated to creating functional and aesthetically pleasing retaining wall solutions for our customers.

Retaining Wall Construction

When it comes to retaining wall work around the home, sometimes it can be difficult to know when you can do it yourself and when you need to call in a professional concrete retaining wall installer. A retaining wall’s footing, block width, elevation and whether it requires a geogrid or other reinforcement will determine the type of retaining wall construction best suited for your project.

1m or more in height.

A structural engineer will also be required to determine the correct hole depths, steel thickness/length and sleeper thickness/length. See retaining wall engineering drawings for maximum heights based on concrete sleeper selection, these drawings can be referred to your engineer.

Small retaining walls and concrete sleeper garden edging that do not exceed 1m or more in height do not require a permit.

Any discrepancies should be referred to the engineer or architect before proceeding with work. 

The document covers general guidelines, foundations, concrete, structural steel, masonry, timber, plastering, roofing, and other miscellaneous topics. It is important to carefully review and understand these guidelines to ensure the successful and safe construction of the retaining wall.

Sleepers are engineered for the use with retaining walls which satisfy the following conditions/limitations:

  • Back wall is free from drainage consisting of sand and or gravel.
  • All sub surface water is drained by means of an argicultuaral drain or other suitable method.
  • Sleepers are handled with care during transportation and erection on site.
  • No machine compaction of back fill is allowed within a distance of 75% of the wall height.
  • Walls over 1 metre require council permission and engineers advice.
