Gabion Baskets: An Introduction

What are Gabion Baskets?

Gabion baskets are rectangular or square cages made of steel wire mesh that are filled with rock. The steel wire mesh cages come in panels or cells that can be stacked and formed into various shapes. Once filled with rock, gabion baskets create a sturdy, heavy structure that can serve a variety of functions.

Some key features of gabion baskets include:

  • Made of galvanized steel wire woven into a mesh pattern
  • Available in various cell sizes, often ranging from 3 to 9 feet square
  • Designed as folded panels that can interconnect to form cages
  • Allow water and air to flow through while holding rock fill in place

They provide stability, prevent erosion, and adapt well to ground movement due to their flexible, porous structure. Gabion baskets have become popular alternatives in construction to concrete structures and all-steel retaining walls.

Gabion Baskets

History and Development

The concept of gabion baskets dates back centuries, when baskets filled with earth were used to fortify military defenses. The modern gabion with wire mesh was developed in the early 1900s for use in civil engineering projects.

Gabion usage greatly expanded starting in the 1930s with soil conservation and revetment projects. Over the decades, polymer coatings and PVC-coated wire were developed to improve corrosion resistance. Manufacturing also improved to allow variable mesh spacing and cell compartmentalization within the gabion panels.

Today, gabion baskets are a well-established infrastructure solution thanks to major improvements to durability, flexibility, and ease of installation compared to earlier gabion designs.

Gabion Basket Construction

Gabion baskets have an all-welded wire mesh construction with heavier gauge wire than traditional wire mesh fencing. The wire is galvanized or coated for corrosion protection when exposed to water and soil.

Gabion panels connect together with wire lacing to form rectangular prism-shaped baskets. Diaphragms within the cells compartmentalize the areas, minimizing bulging when filled and providing reinforcement. Individual panels usually require unfolding, stretching, and fastening together during installation.

Some gabion options feature factory-assembled one-piece cells that unfold easily into ready-to-fill baskets on site. Lids or covers also can be incorporated to enclose the rock-filled gabion baskets if desired.

Key design decisions in engineering competent gabion retaining walls include:

  • Site survey assessing terrain, drainage, soil conditions, water table level and potential surcharge loading
  • Modeling appropriate wall height and batter (backwards slope) to handle modeled pressure without overturning
  • Gabion sizing selection regarding height, depth, and mesh opening dimensions
  • Determining proper reinforcing and foundation requirements per code guidance
  • Sourcing suitably sized rock fill material
  • Any geo-textile separation layer or backfill needs

Gabion Baskets

Gabion retaining walls require adequate reinforced foundations, high-quality baskets proven suitable for retaining use, proper lacing and joining during stacking, packing with graded aggregate layers, and working with the slope when determining face batter angles.

When executed following sound design practices, gabion retaining walls provide long-lasting sturdy support for grade changes using natural durable materials, avoiding potential defects using poured concrete.

Step-By-Step Installation Overview

Constructing a competent gravity gabion retaining wall involves meticulous assembly, joining, filling, and reinforcement:

  1. Excavate for wall footing and pour reinforced concrete foundation
  2. Grade base and set drained aggregate leveling pad keyed into foundation
  3. Assemble initial row of gabion baskets, lace together, then stack upward row-by-row
  4. Place tie-back reinforcement bars and fill cells incrementally with graded stone
  5. Install binding wire ties securing units together every four courses
  6. Backfill behind wall with non-porous fill compacted in lifts
  7. If needed, add geo-textile and porous backfill material behind wall to facilitate drainage

Gabion Baskets

Utilizing certified gabion wall installers is highly recommended. They bring extensive experience establishing proper base prep, basket durability precautions during assembly, cell fill techniques minimizing voids, critical reinforcement steps, and knowledge of drainage needs.
