Guide To Better Retaining Wall Design

Retaining wall style might seem simple to some, but like an iceberg, there’s usually far more going on out of sight with retaining walls than many people understand. And without care, know-how and understanding, a threat looms big.

Maintaining wall failures can cause costly damage to home and services, or perhaps cause severe injury and death. This is why it’s typically best to have a retaining wall developed by an engineer and constructed by an appropriately licensed keeping wall contractor, to make sure a safe, efficient and cost-effective keeping wall service.

In this post, we’ll construct your understanding of retaining walls from the ground up, taking you through the why, what and how of retaining wall style, before talking about how engineers (us in specific) are developing more effective style techniques that result in better outcomes for our customers– be they homeowners/buyers or contractors.

What Is A Keeping Wall?

A keeping wall is a structure that is used to keep the soil at two various elevations (produced by cut and fill) by maintaining the soil laterally and withstanding lateral loads that are applied by earth pressure.

The Australian Requirement, AS4678— Earth Retaining Structures deals particularly with walls that are:

Greater than 800mm and less than 15m in height.

70 ° or more to the horizontal (therefore excluding revetment structures with gentler slopes).

While AS4678 is a national maintaining wall style standard for walls over 800mm, it’s important to note that regional and state federal government requirements differ around Australia. While NSW requires engineering style for any retaining wall over 600mm, the Brisbane, Ipswich and Gold Coast councils typically only need this at 1m or greater. Generally, keeping a steady low-risk bank is ruled out to require a ‘structural’ wall

Picking The Best Wall.

After evaluating the area, soil, design, and drainage, you can start thinking about the kind of keeping wall your task will need. There are a plethora of choices. If the wall comes as a system, designers must work with the product maker for absorption requirements, strength, height variances, and more. If required, the appropriate reinforcement technique needs to be used.

Read on for more information about these wall types to assist you to choose the right keeping wall for your job. Note: the wall heights are noted for reference just.

Segmental Retaining Walls

Utilizes: Various industrial and domestic applications, used for both straight or curved designs. They can be developed to conform to any shape while maximizing the website’s functional area, particularly on high-sloped terrains. When enhanced, they usually have no height constraints.

Segmental retaining walls (SRWs) are developed to be used as a gravity wall either with or without the support and can have heights over 40′. SRWs are modular blocks made from concrete that is frequently dry-stacked without mortar. They also come in a range of textures, sizes, and colours to satisfy the visual requirements of your task.

Styles For Structural Retaining Walls

After you have considered your choices and requirements, it’s time to consider style. There are 4 common kinds of maintaining wall designs that might be fitting for your home or company.

Gravity Retaining Wall

The gravity retaining wall is a simple style that works by using its weight to prevent soil from moving.

Simple Option

Functions well when a basic maintaining wall is all you need

Variety Of looks

Can accommodate making use of lots of products, including brick, pavers, and dry-stacked (unmortared) stone

Great For Brief Walls

Short gravity walls (as much as 10 feet in height) are normally huge enough to stand on their own. However high gravity walls may need extra support such as a concrete footer to add stability.

Cantilevered Retaining Wall

A cantilevered wall is strengthened with steel bars going through its concrete or masonry. Also, this kind of wall is connected to a slab foundation that extends under the soil. This offers the wall, including the base below the soil, an L shape that helps in keeping the wall in location.

Added Strength

Particularly helpful in scenarios where soil may be more likely to push against the wall, such as extremely sloped properties

Great For Tall Walls

Holds up well at heights of up to 25 feet high

Can Be Premade

Can be cast ahead of time in a factory or constructed on-site


Think about these points when preparing your keeping wall installation:

Walls over 4 feet ought to utilize geogrid fabric

Various Block Designs Restrict The Permitted Height

Usage filter material over damp or dry soil, then cover with gravel

Make sure excellent drainage with making use of backfill, drain piping, filter fabric, or weep holes

Constantly Backfill Between Each Layer

Follow the producer’s suggestions

Hardscaping 101: Keeping Walls

You might not even understand it’s there when a retaining wall does its task right. Think about maintaining walls as support hose pipes for sloped surfaces: they hold everything in location. Inconspicuously.

The most standard function of a maintaining wall is to fight, and one hopes, win versus gravity and the forces of nature,” composes our factor, Kier Holmes.

How do you know if your garden needs keeping walls? Ask yourself if your landscape could be improved if you had: more flat, usable land; a hillside terrace; less rainwater overflow, or more seating (low retaining walls can function as benches)?

The very best products to use to develop keeping walls vary from wood (generally the least expensive choice) to put concrete to stone. The product you select should complement the architectural design of the house and other hardscape elements.
