What is a Gabion Basket?

How to spot a bad retaining wall

A gabion basket is a cage-like structure, generally designed to hold rocks to create a natural aesthetic within landscaping. The wires that create the basket are made from a zinc-aluminium alloy that prevents corrosion.

Generally, a gabion basket is filled with medium to large-sized rocks, giving the illusion of a natural structure. It serves as a way to maintain a landscape whilst not compromising on the natural look of nature.

What is the lifespan of a Gabion Basket?

The lifespan of a gabion basket is 10 to 75 years, subjective to the environment it is placed in. The mesh is free from corrosion, but movement in the environment may cause the rocks to wear against the basket’s wiring, resulting in gradual wear and tear which could eventually break the wiring, compromising the whole structure.

The basics of interlocking concrete blocks

Can you use interlocking concrete blocks instead of a gabion basket?

How to build a wall from concrete blocks

Yes, Interlocking concrete blocks can easily be used instead of a gabion basket. Interlocking concrete blocks take much less time to prepare in terms of placement, and generally don’t require foundations before placement either. Additionally, Interlocking concrete blocks are resilient, weather resistant and highly durable.

Gabion Baskets are a practical and aesthetic alternative for those wanting to maintain a natural element to their landscaping. However, the wiring that creates the basket is susceptible to breakage, which can result in the whole structure collapsing.

Interlocking concrete blocks are also much easier to move, relative to a full gabion basket. All they require is heavy-lifting machinery. Moving a gabion basket is difficult as they are generally filled with large rocks of varying shapes and sizes, making it difficult to move without the weight of the rocks re-distributing.

Is a Gabion Basket more expensive than interlocking concrete blocks?

Generally, gabion baskets are the more expensive alternative due to the intricate work required, manipulating the wiring to your specified size, placing the basket and filling the basket with the right size and amount of rocks, then sealing the basket together, not to mention transport and any other requests. Extra costs can also include making foundations for the baskets to be placed.

Interlocking concrete blocks are made from a pre-cast mould, you choose the size and amount you need, and it is delivered to you, interlocking concrete blocks are generally a cheaper option but again is completely subjective to the project you have in the works.
