What is a Gabion Basket?

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.

Why you should choose interlocking concrete block over gabion baskets

Retaining walls explained

There are many factors that only serve to show the effectiveness of interlocking concrete blocks over gabion baskets, which we will share below. The main argument for gabion baskets over interlocking concrete blocks is their look, which seamlessly organises landscapes without compromising on the natural aesthetic.

Here is why you should choose interlocking concrete blocks over gabion baskets:

  • Interlocking concrete blocks do not require foundations to be set before placing them in most instances. Whereas gabion baskets require this, resulting in more time and money spent.
  • Interlocking concrete blocks are durable, and weather resistant. Gabion baskets have weather resistant properties but are prone to its wiring being damaged over time.
  • A full gabion basket is much more difficult to move, getting purchase on it is difficult without possibly causing damage to the basket. Interlocking concrete blocks require regular lifting equipment, or in some cases, a forklift.
  • Gabion baskets must be filled in order for them to serve their purpose, this is another effort of labour which is totally avoided when opting for interlocking concrete blocks.
  • Interlocking concrete blocks can be a cheaper option out of the two.

Why would gabion baskets cost more 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 and shape, 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.

Do gabion baskets or interlocking concrete blocks need cement?

Neither of these options require cement. Interlocking concrete blocks have specific studs and recesses that provide connection and as a result a more sturdier structure.

Gabion baskets can be binded to each other through the use of additional wires, this is subject to the manufacturer and client.
