Gabion Walls Vs Concrete

Gabion basket retaining walls.
Gabion walls vs concrete. Gabion baskets are filled with broken concrete and stones that are also available locally at a much lower cost. Concrete retaining walls are often used but gabion retaining walls have so many favourable qualities. Gabions have been used in many large infrastructural projects for over a hundred years and more recently in domestic situations. Gabion walls have been shown to have about a third of the carbon footprint of a concrete wall.
Gabion structures can also be designed so that re vegetation takes place when plants colonise the interstitial spaces between the rock fill thus returning the solution to nature. The site output to build a gabion wall is 20m3 per gang day using a 360 machine and three men. When the wall is flexible meaning if the top of the wall rotates by 0 001 to 0 003 radians or if the top of the wall deflects at the range of 0 001 h to 0 003 h where h is the height of the retaining wall then the wall deflects and moves away enough from the soil retained that the horizontal soil pressure decreases to the active pressure. If you are considering using gabions here are 5 reasons why they are a great choice.
Moreover the formation of a gabion wall also requires less effort and workforce as compared to concrete walls. The retaining wall toe prevents the gabion wall sliding forwards the depth of the toe needs to increase as the wall gets bigger. A railroad tie retaining wall can last up to 40 years. Gabion basket retaining walls allow water to escape if large stone is used to fill the baskets.
Gabion retaining walls can be designed and configured with a stepped front face or a smooth front face. Consult a gabion wall professionals if you want to build a gabion wall that s over a meter in height. 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. The difference in out put is 5 x faster to build a concrete block retaining wall than a gabion retaining wall.
They are very similar to our concrete block design but can be more economical. Although once they achieve a height of about 16 feet they begin to lose their advantage because of measures that would need to be taken to ensure stability which makes it a more complicated construction process. The site output to build a concrete block gravity retaining wall is 100m3 per day using a tele handler and two men.
