Pros and cons of gabion walls
- 2021/08/15 -
 “I think the big pros are they’re economic, they have little to no maintenance, they’re easy to install and they are very long lasting, and they can be created fairly quickly,” says Jurgensen.

The cost of the wall depends on the wire being used as there are various grades and gauges of wire mesh available, but they are typically all galvanized. The other determining factor on the cost is the fill material being used.

Angular rock is the best gabion fill as they lock together and provide a non-moving unit. Jurgensen suggests using a heavier gauge wire if your customer wants to use a rounded river rock as the fill material to help it maintain its shape.

Jurgensen says unskilled laborers can easily learn to erect, fill and close the wire baskets properly.

“Pilings, underwater drainage systems and excavations are unnecessary,” he says. “There’s no need to drain the site or to construct a cofferdam for underwater installation. The first layer of gabions can be laid in water or in mud.”

Jurgensen says there’s no need to create a foundation for gabion walls as they end up weighing so much when you fill them with rock. He says what anchors the wall is the sheer mass and weight of the structure. The longer it’s there, the more it settles in and the stronger it becomes.

Any gabion wall 3 feet and under does not require the calculation of loads and stress it might take on, but Jurgensen says if you’re going higher than 3 feet you should get an engineer involved to make sure it’s safely constructed.
