Which retaining wall material is the most affordable?
Prices for retaining wall materials range from very affordable to extremely expensive. Treated pine is the most affordable option at $250 per square metre, but it also has its limitations.
These are some cost-saving ideas for retaining walls made from different materials.
- Treated pine is the most affordable material. It won’t last as well as other materials. Galvanized posts between treated pine will prolong the life of the wall.
- Hardwood is generally more expensive than treated pine. It is important to ensure that it has been treated with a treatment that will allow it to resist dirt and water.
- Railway sleepers, which are slightly more costly, are an alternative and can withstand water and ground contact.
- Concrete sleepers can be more costly. Concrete sleepers can be coloured or grey and have a longer lifespan. Concrete retaining walls can be more expensive if you use galvanized steel or concrete posts. This will affect their durability and appearance.
- Besser blocks can be expensive to install, but they have a long life span.
- There are many prices for interlocking concrete blocks. These blocks are very versatile in appearance. There are curved and straight blocks and corner blocks and capping. These blocks are ready for DIY installation. Retaining wall builders can quickly construct a wall if the wall exceeds the height allowed for DIY construction.
- To make it more manageable, sandstone can be ground into a form that looks like natural sandstone. You can make it look like natural sandstone by remaking it in molds. However, it will have a more consistent shape because it is made from molds.
- Natural stone can be very expensive or relatively cheap. The most expensive option is the one that has been cut.
