GABION FENCES

Gabion fences are narrow free standing walls constructed of sturdy wire mesh baskets with natural stone fillers. They have become the architect's and landscaper's choice for creating natural appealing barriers for privacy, security and noise control.

Available in standard widths from 12" to 18" and heights from 4' to 8' they maintain their stability using internal posts imbedded in concrete footers or can be attached to an existing concrete foundation using base plates and concrete anchors.

There are several tools required for installing a gabion rock fence and having the right tools is essential for a smooth and efficient installation. The essential tools include a post hole digger, compactor, shovel, level, string, measuring tape, pliers, wire cutters and hammer. The post hole digger or powered auger will be used to dig holes for the fence posts, while a shovel is used to remove dirt and debris. The level ensures that the posts are set at the proper alignment, while pliers and wire cutters are used to manipulate and cut wire materials. The hammer is used to drive posts and stakes, for attaching the string. The string line keeps the fence post straight and true. Having all of the necessary tools on hand before beginning the installation process can save time and minimize disruptions.

STEP 1

PREPARE THE FENCE BASE

The first step in installing a gabion rock fence is to prepare the base. Using a hoe or flat shovel, remove any grass, weeds or debris. The fence may be set directly on the existing soil or excavated and filled 6" deep with compacted gravel.

STEP 2

LAY OUT THE FENCE LINE

The first step when setting the support posts is to determine the location of the fence by setting stakes and string line at the ends of the fence. Use a measuring tape to locate the support pole holes and mark each hole spots with spray paint. Then, dig a hole for each post using a post hole digger or powered auger, making sure that the holes are deep enough to support the height of the fence. Typically 3 to 4 ft deep for a 6 to 8 ft high wall.

STEP 3

DIG POST HOLES

Dig a hole for each post using a post hole digger or powered auger, making sure that the holes are deep enough to support the height of the fence. Typically, 3 ft deep for a 6' high fence and 4 ft deep for a 8 ft high fence.

STEP 4

CONCRETE POST HOLES

Place the fence post in the hole, making sure it is level, and then pour concrete mix around the fence post holes. Premixed bags of concrete may be mixed by hand in a wheelbarrow with a shovel, or with a powered concrete mixer. Allow the concrete to dry completely before proceeding to the next step.

ALLOW TIME FOR CONCRETE TO DRY

It is important to let the concrete dry before proceeding with installing the gabion baskets because the concrete provides the stability and support necessary to hold the fence in place. By allowing the concrete to dry completely when installing the gabion rock fence, you can ensure that the fence is securely anchored in place which will improve its durability and longevity.

STEP 5

PURCHASE MATERIALS

It is important to carefully measure, estimate and purchase the correct amount of gabion baskets and fill rock fill materials to avoid delays or additional expenses. Underestimating the amount of materials needed can result in having to stop the installation process and purchase additional materials, causing delays and adding to the overall cost of the project.

STEP 6

ASSEMBLE THE GABION BASKETS

Standard gabion baskets come pre-assemble and delivered stacked flat on wooden pallets. Cut the bands, remove the basket and unfold. Start the erection with the base panel laying on a flat surface, then lift and secure the side panels with temporary hog ring fasteners. Lift the basket and slip it over the internal support posts. Place additional baskets end to end and secure with helical spirals or hog rings and bracing ties to prevent bulging.

STEP 7

FILLING THE GABION BASKETS

Use indigenous rocks if available or angular quarried rocks measuring 4 to 6 inches.

Careful packing of the rock takes time but is important!
Work in layers, using smaller pieces to fill any voids and to wedge the best looking rocks against the face of the basket. Orient them as closely as possible, then filling in behind to hold them in place.

STEP 8

ADDING LAYERS

To obtain fence heights taller than 3' you generally stack multiple baskets on top of each other. Once you have packed the lower basket, wire close its lid and then assemble the second layer on top. Fill the second layer like the first using the best looking rocks on the face and the less attractive fill rocks in the center.
