What Is Retaining Walls Adelaide Used For?
Retaining walls are generally used for retaining soil lateral to the front of a building. They may also serve as decorative features around the property, especially if you want to create a focal point or “high point”. Retaining walls Adelaide also provide homeowners with the option of shading a view or creating a private space. There are numerous options available when constructing a retaining wall. These include brick, concrete and vinyl.
Brick is an inexpensive option that is also relatively strong. Because of its durability and fire-retardant properties, bricks are the most popular selection for retaining walls. There are two types of bricks to consider; tractor brick and two-toned. The first type contains cement to form the face of the wall while the second has earth behind it to act as an anchor.
Concrete blocks are used as the foundation for retaining walls Adelaide. They are solid and relatively inexpensive compared to other types of material. Unlike other materials, concrete blocks do not need to be reinforced. Concrete blocks are lightweight and flexible. They provide the perfect amount of flexibility without weighing down the wall as other materials often do.
When soil is placed on the exterior of a retaining wall, additional reinforcement is needed to hold the soil in place. Professional landscape designers do landscaping. Landscape fabric is placed on top of the soil once it is filled with dirt. Additional fabric is added to the wall once it has cured to hold it in place.
Concrete or metal anchors are used to reinforce the retaining walls. Metal anchors are anchored into the earth behind the wall using steel rods or screws. A disadvantage to using metal anchors is that they must be replaced after approximately ten years because the metal is weaker than the earth behind it.
Slopes are often flat. When soil is placed on a hill, the retaining walls Adelaide must be constructed differently. Instead of a flat surface, the slope must be augmented or strengthened. This process is called levelling or compaction.
The most common way to level a slope is by using concrete. Companies that provide landscaping services use concrete footers and retaining walls that are bolted to the ground. The footers are typically four to six inches deep. The retaining walls are constructed from flexible pieces of material bolted together and form a solid base for the walls. Once the concrete blocks are placed in place, they are cemented together to form a strong, waterproof foundation.
To build a robust and concrete wall, engineers use steel rods inserted vertically into the earth. The rods are driven deep into the earth so that when the soil shifts, the walls don’t move. To keep soil from shifting, engineers use steel wedges to level the slope. After the hill is levelled, a skid system can load the concrete blocks evenly into the holes. To add more weight, concrete is pumped into the system.
