Retaining walls

Creating a retaining wall is an important and practical way to level off any sloping ground. At AEP Pools and Landscapes we have the experience and skills to create any retaining wall to meet your residential requirements. The construction of these can been complicated and may need engineering to ensure they are strong enough to withstand the forces applied to them. There are numerous options available when creating a retaining wall, each with their own aesthetic and practical benefits, which that our expert team can advise you about.

TIMBER RETAINING WALLS

These are walls where both the posts and sleepers constructed using timber – either a hardwood such as redgum or ironbark, or softwood such as H4 treated pine. The posts are generally placed in front of the wall so any pressure from the sleeper and soil push against the posts. In the past this was the most common form of residential retaining wall construction.

MASONRY RETAINING WALLS

Masonry retaining walls are constructed using cement blocks (either textured or plain) or bricks on a concrete footing. Depending on the height of the retaining wall, the blocks may need to have internal reinforcement and be core filled with concrete. Once constructed, masonry walls can be rendered or clad with a variety of different materials such as stacked stone.

ROCK RETAINING WALLS

Rock retaining walls comprise of rocks placed in a tiered fashion to retain the soil behind them. This tiering can be created to look organic such as you would see in nature, or stacked to create a rock wall. There is a wide variety of looks and feels that can be achieved, as the walls can be created from any rock material.

GABION RETAINING WALLS

Gabion retaining walls comprise of wire baskets that have been filled by loose rocks, which are then stacked to create the wall. They provide an architectural alternative to the traditional retaining wall.

STEEL OR ‘I’ BEAM RETAINING WALLS

These are walls where the posts are galvanised steel sections with sleepers inserted between them. The benefits of these retaining walls include having a strong post that will not bend or twist (which may happen over time with timber posts) as well as leaving a flush front edge to the retaining walls. This is especially useful when you don’t want the post encroaching on a usable area. With steel retaining walls you also have the benefit of a choice of sleepers. You can use traditional timber steepers or concrete sleepers, for which there is an increasing range available.
