When Do You Need to Replace Your Old Wood Retaining Walls? 

Safety hazards. There are many reasons to replace an old wooden retaining wall, but this is clearly a must once the wall is a hazard to yourself or others.  How can you be sure they are hazardous? Frist, there are typically visual cues like boards splitting apart, grass growing between the joints, soil falling out, or rotten wood that can be picked away with your hands. There may even be a negative lean on the wall. This means when you look at it sideways, it’s leaning too far over – one heavy rainfall could cause it to collapse. 

Replacing Old Wood Retaining Walls

Replacing old wooden retaining walls is a MUST!

Looks are important. The other reason is purely for looks. Some of the old, failing timber walls are just plain ugly and need to be replaced. This will also increase the value of your property, since curb appeal has a huge impact on home sales. More importantly, it will increase your appreciation and enjoyment of your outdoor space.

Reasons to Not Use Treated Timber Retaining Walls

Healthy walls, healthy property. Unfortunately, treated timber wood may have cancer causing carcinogens from the manufacturing process. It’s a known fact that the preservatives used to make them last a long time have cancer causing agents in the process, therefore touching them can be hazardous. Not to mention, that can only have negative impacts for the environment and your health. 

Wood walls tend to rot overtime. The main culprit of any retaining wall failure is nearly always water and wood retaining walls are no different. Water soaks into the wood and starts to deteriorate and rot out from the back. Knowing this, you may not be able to tell when the wall is starting to fail. 

Treated timber can be difficult to work with. It may sound simple and obvious, but these blocks of wood can be extremely heavy and cumbersome. Lifting some of the beams could even take machinery or heavy equipment in order to properly install them. Don’t let yourself be fooled by the light and fluffy wood look! It’s been treated and is often water-logged and heavy by the time installation begins.

Why Use Concrete Interlocking Wall Blocks? 

Long-lasting strength. The top reason to use interlocking concrete block walls is that they last a long, long time! It’s concrete, and if properly manufactured, could last a lifetime. The average design life of a SRW (segmental retaining wall) systems is 75 years. Needless to say, that’s far longer than the average 4.5 years that people stay in their homes. 

They can be reused.  That’s right, these blocks can be taken apart, cleaned up and reused again. It’s a practical choice for those people who aim to be cost-efficient. Concrete blocks can be used for several purposes, since they can be curved, turned and stepped very easily for optimal functionality

Concrete interlocking retaining walls look great.  With most suppliers, distributors and manufacturers, you can choose from different colors, styles and sizes of retaining wall blocks. Check with your local producer for where to buy and ask for samples that match what you are trying to achieve for your outdoor space.
