How much does a gabion wall cost?

Gabion baskets cost $15-$50 each. Stone fill runs $25-$75 per ton delivered. A 20-foot wall that is 3 feet high typically costs $500-$1,500 for materials. Labor adds $20-$40 per square face foot if hiring a contractor.

How long do gabion walls last?

Gabion walls with galvanized or PVC-coated wire last 50-100 years. The stone fill is essentially permanent. Standard galvanized wire lasts 40-60 years and PVC-coated wire exceeds 100 years in most environments.

What size stone works best for gabion baskets?

Stone should be 1.5 to 2 times the mesh opening size, typically 4-8 inches for standard baskets. Angular crushed stone is preferred over round river rock because it interlocks and creates a more stable structure.

Gabion Calculator

Gabion walls are wire mesh baskets filled with stone, used for retaining walls, erosion control, and landscaping. Enter your wall dimensions to calculate how much stone fill you need and how many standard baskets to order.

A gabion wall measuring 20 feet long, 3 feet high, and 3 feet deep requires 180 cubic feet of stone fill -- about 6.7 cubic yards or 9 tons. That takes roughly 7 standard 3x3x3 baskets.

Choosing gabion stone: The fill stone should be larger than the mesh openings (typically 4-8 inches diameter). Angular crushed stone locks together better than round river rock, creating a more stable wall.

Installation tips:

Place baskets on a level, compacted base
Wire baskets together with lacing wire for structural integrity
Fill in 12-inch layers, hand-placing face stones for a clean look
For walls over 3 feet high, step back each course or consult an engineer
