A retaining wall is the most cost-efficient and practical way of making use of rough areas on your land or property. If you happen to own land with hills, slopes, or mountainous terrain, retaining walls Gold Coast are your solution to taking advantage of what you have.
The good thing about retaining walls is that you can build them using different materials, which in turn means you also have several types to choose from; including stuff like concrete, timber, stone, steel, brick, and even vinyl. But this time, let us talk about the most popular versions of retaining wall in Australia.
1 – Gravity Wall
The earth exerts massive pressure, and the role of the gravity wall is to resist it by using its mass and weight. It features an average height of three to four feet, and it consists of mortar-less stone or masonry units. Due to its sturdy construction, it holds back the earth or soil. Gravity retaining walls include of a volume of materials which is stacked together to create a higher weight or force of friction to overpower the force exerted by the soil. ‘Battering’ is a type of process that is known to help the walls enhance its stability by leaning back into the retaining soil. Battering is done to extend the lifespan of gravity walls. However, this type of wall is complicated to build since it demands a high quality of building materials.
2 – Cantilever
Cantilever walls feature a uniform thickness and ties to a footing. It is among one of those taller retaining wall and single layered walls. If an engineer builds it correctly, it will help to hold back enough soil. It is usually present on basements of a house.
3 – Counterfort
Regarding appearance and construction, counterfort retaining wall is quite identical to cantilever walls. The only difference is the additional benefit this type of wall offers which is the strength provided by the triangular walls. It features a triangular structure that connects the top of the wall and the back of the footer to extend its durability. All the three structures of the footers, retaining walls and other additional walls incorporate steel that makes it more powerful to stand the test of time. Due to the rectangular walls of counterfort retaining walls Gold Coast, they are attached to the footers all the time. Also, only professional engineers can build this type of wall at its best.
You usually see concrete retaining walls serving to beautify gardens or outdoor landscapes. It specifically serves as a support to uneven or vertically-slanting slopes in the yard. This kind of retaining wall is highly-built and have more depth and heavier soil underneath which results to better resilience and solidity. Concrete walls demand greater base depth to create a better foundation. If you have correctly installed this retaining wall, you won’t experience issues like tilting, bowling, or cracking.
