Buying Guide for Best Below Ground Wood Preservatives
When it comes to protecting wood from rot, decay, and insect damage, using the right preservative is crucial. Below ground wood preservatives are specifically designed to protect wood that is in contact with the soil, where the risk of damage is highest. With so many options available, choosing the right preservative can be overwhelming. In this guide, we will discuss the key factors to consider when buying below ground wood preservatives to ensure you make an informed decision.
Active Ingredients
The active ingredients in a below ground wood preservative are the key to its effectiveness. Different preservatives contain different active ingredients, each with its own strengths and weaknesses. Some common active ingredients include copper, borate, and arsenic. Copper-based preservatives are popular for their ability to protect against a wide range of insects and microorganisms, while borate-based preservatives are known for their low toxicity and environmental impact. Arsenic-based preservatives, on the other hand, are highly effective but can be toxic to humans and animals.
The choice of active ingredient will depend on the specific needs of your project. If you are looking for a preservative that is safe for use around pets and children, a borate-based preservative may be the best choice. If you need a preservative that can protect against a wide range of insects and microorganisms, a copper-based preservative may be more effective. It is essential to carefully consider the active ingredients in a preservative before making a decision, as this will have a significant impact on its effectiveness and safety.
Concentration and Application Rate
The concentration and application rate of a below ground wood preservative are critical factors to consider. The concentration of the active ingredient will determine how effective the preservative is, while the application rate will determine how much preservative is needed to achieve the desired level of protection. A higher concentration of active ingredient may be more effective, but it can also be more expensive and potentially toxic. The application rate will depend on the specific needs of your project, including the type of wood being treated and the level of exposure to soil and moisture.
The application rate of a preservative can vary significantly depending on the product and the manufacturer’s instructions. Some preservatives may need to be applied at a rate of 1 gallon per 100 square feet, while others may require a rate of 1 gallon per 50 square feet. It is essential to carefully follow the manufacturer’s instructions to ensure that the preservative is applied at the correct rate. Applying too little preservative can result in inadequate protection, while applying too much can be wasteful and potentially toxic.
Wood Type and Compatibility
The type of wood being treated is a critical factor to consider when choosing a below ground wood preservative. Different types of wood have different levels of natural resistance to rot and insect damage, and some preservatives may be more effective on certain types of wood. For example, preservatives containing copper may be more effective on softwoods such as pine and spruce, while preservatives containing borate may be more effective on hardwoods such as oak and maple.
The compatibility of the preservative with the wood is also essential to consider. Some preservatives may react with certain types of wood, causing discoloration or other damage. For example, preservatives containing arsenic may react with cedar wood, causing it to turn black. It is essential to carefully consider the type of wood being treated and choose a preservative that is compatible with it. This will help ensure that the preservative is effective and does not cause any damage to the wood.
Environmental Impact
The environmental impact of a below ground wood preservative is a critical factor to consider. Some preservatives can be toxic to humans, animals, and plants, and can contaminate soil and water. Preservatives containing arsenic, for example, have been linked to environmental contamination and health problems. On the other hand, preservatives containing borate are generally considered to be safer and more environmentally friendly.
When choosing a below ground wood preservative, it is essential to consider the potential environmental impact. Look for preservatives that are labeled as “environmentally friendly” or “non-toxic,” and choose products that are specifically designed to minimize environmental impact. Some preservatives may also be certified by organizations such as the Environmental Protection Agency (EPA) or the International Code Council (ICC), which can provide assurance that the product meets certain environmental standards. By choosing an environmentally friendly preservative, you can help minimize the risk of contamination and protect the health of humans, animals, and plants.
Cost and Value
The cost of a below ground wood preservative is a critical factor to consider. Preservatives can vary significantly in price, depending on the active ingredient, concentration, and application rate. While it may be tempting to choose the cheapest preservative available, this can be a false economy. A cheaper preservative may not provide adequate protection, and may need to be reapplied more frequently, which can increase the overall cost.
When evaluating the cost of a preservative, it is essential to consider the value it provides. A more expensive preservative may be more effective and longer-lasting, which can provide better value in the long run. Look for preservatives that offer a good balance of cost and effectiveness, and consider the potential long-term savings of choosing a higher-quality product. By investing in a high-quality preservative, you can help protect your wood from rot and insect damage, and ensure that it lasts for many years to come. The best below ground wood preservatives will provide a good balance of cost and effectiveness.

Frequently Asked Questions
What are below ground wood preservatives and how do they work?
Below ground wood preservatives are chemical treatments designed to protect wood from rot, decay, and insect damage when it is in contact with the ground. These preservatives typically contain ingredients such as copper, borate, or arsenic, which are toxic to the microorganisms and insects that can damage wood. When applied to the wood, these preservatives help to prevent the growth of fungi and bacteria that can cause rot and decay.
The preservatives work by creating an environment that is unfavorable for the growth of these microorganisms. For example, copper-based preservatives react with the moisture in the wood to form a toxic compound that inhibits the growth of fungi and bacteria. Similarly, borate-based preservatives work by disrupting the metabolic processes of the microorganisms, ultimately leading to their death. By preventing the growth of these microorganisms, below ground wood preservatives can help to extend the lifespan of the wood and prevent costly repairs or replacements.
What types of wood can be treated with below ground wood preservatives?
Below ground wood preservatives can be used to treat a variety of types of wood, including lumber, plywood, and oriented strand board (OSB). The specific type of preservative used may depend on the type of wood being treated, as well as the intended use of the wood. For example, wood that will be used for structural purposes, such as foundation walls or footings, may require a more robust preservative treatment than wood that will be used for non-structural purposes, such as landscaping or decking.
It’s also important to note that some types of wood are more susceptible to rot and decay than others, and may therefore require more frequent or intensive preservative treatments. For example, wood that is high in moisture content, such as green lumber, may be more prone to rot and decay than wood that is dry and well-seasoned. In these cases, a more aggressive preservative treatment may be necessary to ensure the long-term durability of the wood.
How do I choose the best below ground wood preservative for my project?
Choosing the best below ground wood preservative for your project depends on a number of factors, including the type of wood being used, the intended use of the wood, and the local climate and soil conditions.
