The type of backfill soil specified will determine the type, and placement of the geotextile filter fabric. Fill with 3" - 6"  angular shaped rocks, Specific gravity required for the rock fill shall be determined by the design and specified by the design engineer. DURA-WELDTM Gabions:  3" x 3" square mesh openings - 4" - 8" angular shaped rocks, DURA-FLEXTM  Gabions: 3-1/4" x 4-1/2"  - 8x10cm hex shaped mesh openings.

Gabions are cheaper to construct because you do not need to assemble a team of skilled workers to erect a wall. The cost of labor is minimal compared to a traditional New England fieldstone wall.”. N.B. Gabion walls with a stepped front face shall have a minimum 1’-1.5’ horizontal setback for each 3’ vertical lift.

Installation can be temporary or permanent. For wall heights of 18’- 36’ consider two separate walls divided by a level plateau or see the Stable Slope Section of this web site. All Rights Reserved. Retaining walls supporting heavy surcharges and driveways, Erosion control gabions.

Some of the tools you are going to need to build a gabion wall include: With proper planning and workmanship, gabions can be built using cheap, environmental-friendly materials. When utilizing a gabion wall with a smooth front face, the gabion wall should be placed on a 5-6 degree batter and is not recommended for walls above 18’ high. Some of the factors to keep in mind when constructing a gabion include: choice of the construction site and access and availability of construction materials.

The cages were originally wicker, but now are usually a welded mesh made of sturdy galvanized, coated, or stainless steel wire that won’t bend when filled with rocks. Square gabions Height = Thickness. Gabion gravity retaining walls constructed without the placement of filter fabric will have a tendency to incur a loss of retained soils and grade elevation behind the gabion wall. If left to the elements, algae can easily grow on the walls and diminish the aesthetic impression. SOURCEBOOK FOR THE CONSIDERED HOME Large spaces in the wall could become home to rodents. Gabion walls can be made in virtually any size (within structural limitations) for site-specific needs. Consider Hog Wire Fencing. Gabion stone walls are an attractive and functional gravity retaining wall system made from galvanised steel mesh filled with stone, brick or concrete.

The first gabion walls were erected some 7000 years ago to prevent soil erosion along waterways. To increase the bearing capacity, minimize differential settlement, and/or allow for additional drainage, a base layer of granular stone fill with consistent gradation ranging from ½” to1-1/2" may be placed and compacted to local standards 6” – 18” in depth. The cost of building a gabion depends on the chosen materials as well as the design and scope of the project. Please check Local, State and Federal requirements. Gabion gravity retaining walls are typically placed directly on a graded soil foundation.

Copyright © 2007-2020 Remodelista, LLC. This will result in the internal diaphragms being placed perpendicular to the wall face and parallel to soil thrust. Note: A professional stability analysis may determine that the gabion gravity retaining wall base width could be less or greater than the 2/3 wall height rule. Gabions have varied applications in landscaping, civil engineering and road building.

DURA-WELD and DURA-FLEX gravity retaining walls can be designed and constructed up to approximately 30’, however due to the configuration of gabion gravity retaining walls their best suited for wall heights of 18’ or less. Construction waste was dramatically reduced by using excavated material as filler.

Derived from an old Italian word, gabbione, meaning “big cage,” gabions are enclosures that can be filled with any sort of inorganic material: rock, brick, or concrete debris.
