5 Reasons to Choose Gabions Over Concrete Retaining Walls
There are many aspects to consider when designing a retaining wall, not only the materials to use but also the aesthetic and environmental impact. 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. If you are considering using Gabions, here are 5 reasons why they are a great choice!
Gabions do not have a negative impact on the environment compared to concrete structures, which can leave a high carbon footprint. Carbon footprint analyses show that the use of Gabions can reduce CO2 emissions by up to 80%. Gabions can improve the environmental quality even further if vegetation is allowed to grow around the Gabions.
2. Durable and Long Lasting
Prospect Contractors only install quality assured Maccaferri Gabions. These baskets have double twisted PVC coated Galfan wire, which offers up to three times more protection against corrosion than zinc coated wire. Maccaferri Gabion baskets can have a lifespan lasting 100+ years.
With any retaining wall, proper drainage must be provided to reduce the hydrostatic pressure of ground water behind the wall. Gabions are permeable and allow moisture to pass through, which makes them especially suitable in aquatic environments such as marine and river. Concrete however, can develop cracks due to excessive pressure and even from changes in temperature.
4. Aesthetically Pleasing
As Gabions are filled with natural rock (which are often sourced from the local area) they blend beautifully with their surroundings. Again, if vegetation is allowed to establish, this helps the retaining wall blend in with the environment even further. Concrete on the other hand can look cold and harsh in a natural environment, especially in settings like creeks and rivers.
5. Quick and Cost Effective
Gabions can be quicker to install compared to concrete, as no footings or curing are required. This also helps keep the cost down, making Gabions a more economical solution.
