Types of treatment for landscaping timbers
Landscaping timbers are treated to enhance their durability and extend their lifespan. While there are various types of treatments for landscaping timbers, the most common are:
- CCA (Chromated Copper Arsenate) – This treatment involves using copper, chromium, and arsenic to protect the timber from insects and decay. It is effective in preventing rot and can last up to 40 years.
- ACQ (Alkaline Copper Quaternary) – This treatment involves using copper and a quaternary ammonium compound as preservatives to protect the timber from decay. It is also effective against termites and other wood-boring insects.
- Creosote – This treatment involves using creosote oil to protect the timber from insects and decay. It has been used for over a century and can last up to 25 years. However, it is not recommended for use in vegetable gardens or where it may come in contact with food.
It is important to note that CCA has been banned in some countries due to its potential risks to human health and the environment. As a result, ACQ and other alternative treatments have become more popular.
Benefits of Treating Landscaping Timbers
Landscaping timbers are commonly used in many landscaping projects, from creating garden borders to building retaining walls. Treating landscaping timbers refers to the process of applying chemicals to the wood to improve its durability and resilience to outdoor elements. Here are some of the benefits of treating landscaping timbers:
- Longevity: Treated landscaping timbers have a longer lifespan than untreated timbers. The chemicals used in the treatment process make the wood more resistant to rot, decay, and insect damage, which allows them to last longer.
- Better Appearance: Treated landscaping timbers are often more aesthetically pleasing than untreated ones. The chemicals used can give the wood a more consistent, appealing color, and can protect it from weathering and other forms of wear and tear.
- Increased Safety: Treated landscaping timbers can be less prone to splitting, warping, or cracking, which can help to avoid potential hazards in the landscape. This is particularly important in situations where the timbers are used as retaining walls or other structural elements.
The treatment process involves chemical pressure treatments that penetrate the wood fibers, providing protection from moisture, rot, insects, and decay. The treatment chemicals, such as Alkaline Copper Quaternary (ACQ) or Copper Azole (CA), are environmentally safe and approved by regulatory agencies.
| Treatment Type | Main Benefits |
|---|---|
| Alkaline Copper Quaternary (ACQ) | Long-lasting, good resistance to rot, insects, and decay. |
| Copper Azole (CA) | Long-lasting, good resistance to rot, insects, and decay, suitable for contact with humans and animals. |
Ultimately, treating landscaping timbers can add value to your landscaping project by increasing its durability, aesthetic appeal, and safety.
Common chemicals used to treat landscaping timbers
Landscaping timbers can be treated with a variety of chemicals to increase their longevity and protect them against decay, insects, and other damage. Here are some of the most common chemicals used in treating landscaping timbers:
- CCA (Chromated Copper Arsenate): CCA is a highly effective wood preservative that is commonly used in outdoor applications. It consists of copper, chromium, and arsenic, which work together to protect wood from decay fungi and insect damage. Arsenic is a potent toxicant, which makes CCA-treated wood controversial. However, the EPA has approved its use in certain applications, including landscaping timbers, as long as they are labeled for “residential use only.”
- ACQ (Alkaline Copper Quaternary): ACQ is a water-based wood preservative that is an alternative to CCA for outdoor applications. It contains copper, which is highly effective against decay fungi and termites, as well as a quaternary compound that enhances its effectiveness. ACQ-treated wood is considered safe for use in residential applications.
- Creosote: Creosote is a petroleum-based wood preservative that is highly effective against decay fungi, insects, and fungi. However, it has a strong odor and is considered a hazardous substance due to its toxicity. Creosote-treated wood is not recommended for use in residential applications.
Side effects and precautions
While these chemicals are effective at protecting landscaping timbers, they can present health and environmental hazards if not handled properly. Here are some of the side effects and precautions associated with these chemicals:
- Exposure to CCA-treated wood dust or chips can increase the risk of cancer, skin irritation, and other health effects. Use appropriate protective gear, such as gloves and respirators, when working with CCA-treated wood.
- ACQ-treated wood can corrode certain metals, such as aluminum and steel. Avoid direct contact between ACQ-treated wood and these metals.
- Avoid burning CCA- or creosote-treated wood, as this can release toxic fumes into the air.
- Dispose of treated wood properly, according to local regulations. Do not reuse or repurpose it without verifying that it is safe to do so.
Treating timbers safely and responsibly
If you choose to use treated timbers in your landscaping project, it is important to do so safely and responsibly. Here are some tips to keep in mind:
