Though many people may not be familiar with the technical name, gabion retaining walls are hardly an uncommon sight. Featuring wire cages filled with heavy material (usually rocks), gabion walls are used in everything from landscaping to erosion control. In the latter context, they have an especially large number of benefits that may not be immediately apparent to the casual observer. If you are in need of a retaining wall, take a look below to discover just a few of the advantages of utilizing a gabion wall.
Cost
When comparing the different types of retaining walls, you're unlikely to find one that is more affordable than a gabion wall. Splurging on a wall that uses more expensive materials—such as lumber or some kind of alloy—is rarely the right decision unless the circumstances absolutely require it. Gabion walls, on the other hand, are impressive in their simplicity. They don't require more than solid wire and as much crushed rock as is needed. In fact, they don't even need a concrete foundation. For those who need to stick to a tight budget, gabion walls are the perfect fit.
Durability
Another highly significant advantage of gabion walls is that just because they are inexpensive doesn't mean they require compromise on other important attributes such as durability. In fact, gabion walls are well known for their longevity; those located near large bodies of water may see the wire rust somewhat more frequently, but are nevertheless made to last for decades. They are never at risk for the kinds of cracks and stress fractures that can affect other materials, and are impervious to all but the most extreme water pressure. When it comes to choosing a retaining wall, there are few choices tougher and more long-lasting than gabion walls.
Ease of Construction
Another great feature of most gabion retaining walls is how easily they can be constructed. Building retaining walls taller than a meter is better left to engineers and other professionals who know how to erect them, but smaller gabion walls can be easily constructed by someone with the adequate tools and some free time. It is most important to keep in mind that the wire cages should be filled in slowly, so as to avoid creating a sudden lopsided shape in the wall. Finally, when the cages are filled, make sure the lids of the top layer are closed properly with tie wire.
