Gabions Confine Stone For Erosion Protection and Retaining Soil

Gabions are rectangular wire mesh baskets filled with rock that can be placed on slopes and channels for erosion protection or stacked to create retaining walls. They have been used for decades to solve a variety of erosion based engineering dilemmas because of their flexibility and unique design characteristics. Gabions are especially useful in stream and channel applications where there is both a need for a natural look and high amounts of water flow are expected.

Key aspects of why gabion wall design and construction can be extremely beneficial are:

  • Gabions, along with geotextiles, can create retaining walls that are even more effective than concrete as they allow for drainage and settling without adversely affecting the strength or lifespan of the wall. As an additional bonus, the material and labor cost involved in constructing gabion retaining walls adds up to be less than that of a concrete wall, allowing contractors the ability to offer more competitive bids and still keep their profit margins high.

  • They are incredibly easy to install and do not require skilled laborers. In addition, they can be filled with material that is already on site. This saves money as more materials do not need to be purchased and the materials used do not have to be disposed of.
  • The cracks between the rocks used to pack gabions are frequently filled with soil to encourage plant growth, which makes gabion retaining walls ideal for projects where beauty is a must, such as controlling soil erosion along waterways that run through residential areas that need to be both long lasting and visually pleasing.

Gabions are being used all over the world as more contractors and engineers strive to incorporate sustainability into their designs and installations. The wire used to build gabions is manufactured in such a way that even if cut or broken the gabion will not collapse, and this factor, combined with the option of purchasing pre-assembled units for faster installation makes them an easy choice for anyone looking for a simple, strong, and cost effective solution.
