Gabions are rectangular cages or containers that are fabricated by thick galvanised wires. They can be coated with PVC and are often filled with rocks, concrete, sand or soil.
A gabion can come in a variety of forms such as a box, basket, mattress or sack.
They can also be stacked onto one another to form a gabion retaining wall.
As a building material supplier in Singapore, Progress Abms carries many types of gabions that have high tensile strength, suitable for any project.
Advantages of Gabion
- Durable and strong
Gabions have a high resistance to atmospheric corrosion due to their PVC coating and their ability to support the growth of vegetation. They are also capable of resisting torrential force, flood force, ice pressure and earth pressure.
- Environmentally friendly
Recyclable materials can be placed inside gabions. Overtime, the gaps in the soil between these materials also allow vegetation to grow.
Its permeable nature eliminates the need for drainage pipes to be installed.
- Reduces water erosion
Soil erosion can be reduced by gabions as they lower the velocity of the water passing through it.
Gabion structures are perfectly scalable and can be used for small-scale projects or massive constructions.
Gabions are known to be economically viable in terms of both material and labour costs.
Common Applications of Gabion
- Rivers and dams
- Interior design
- Marine ports
- Ferry terminals
FAQs About Gabions
Gabions are PVC-coated wire cages filled with rocks and other materials such as sand, concrete and soil. They are often used as a solution to prevent soil erosion and sedimentation due to their ability to reduce water velocity.
1. Gabion baskets
Gabion baskets are the most widely used type of gabions. They are wire mesh boxes filled with rocks of various sizes.
2. Gabion mattresses
Gabion mattresses, otherwise known as reno mattresses, are lower in height than that of gabion baskets. They are able to cover a large area and are flexible to suit different kinds of terrain.
3. Gabion sacks
This type of gabion is typically cylindrical or rounded in shape. It is flexible and can be installed easily.
4. Gabion walls
Gabion baskets or cages are stacked on top of one another to create gabion walls. They are aesthetically pleasing, durable and require little maintenance.
