Tarp for Wood Pile: Best Picks (7 Pro-Tier Cover Options)

It’s ironic, isn’t it? We spend so much time and effort felling trees, bucking logs, and splitting firewood, only to have all that hard work undone by… rain? The truth is, properly protecting your firewood pile is just as crucial as any other step in the wood preparation process. A soggy woodpile is a useless woodpile. In this guide, I’ll walk you through choosing the best tarp for your wood pile, ensuring your fuel stays dry and ready to burn when you need it most.

Why Protecting Your Firewood Matters

Before we dive into the tarp options, let’s understand why protecting your firewood is so important.

• Combustion Efficiency: Dry firewood burns hotter and more efficiently, producing more heat and less smoke. Wet wood struggles to ignite, smolders, and creates creosote buildup in your chimney, which is a fire hazard.
• Heating Value: The moisture content of wood directly affects its heating value. Green wood can have a moisture content of over 50%, while seasoned wood ideally has a moisture content of 20% or less. Burning green wood wastes energy as the heat is used to evaporate the water instead of heating your home.
• Prevention of Rot and Decay: Excessive moisture promotes the growth of fungi and bacteria, leading to rot and decay. This not only reduces the heating value of the wood but also makes it structurally unsound.
• Reduced Insect Infestation: Dry wood is less attractive to wood-boring insects like termites and carpenter ants. Keeping your firewood dry helps prevent infestations that can spread to your home.

Key Concepts: Understanding Wood and Moisture

To make informed decisions about protecting your firewood, it’s essential to understand a few key concepts:

• Green Wood vs. Seasoned Wood: Green wood is freshly cut wood with a high moisture content. Seasoned wood has been dried for a period of time, typically 6-12 months, to reduce its moisture content.
• Moisture Content: Moisture content is the percentage of water in the wood relative to its dry weight. As mentioned earlier, seasoned firewood should have a moisture content of 20% or less for optimal burning. I use a moisture meter regularly to check my wood. A good moisture meter is an essential tool.
• Seasoning Process: Seasoning involves stacking firewood in a way that allows air to circulate freely, promoting evaporation of moisture. This typically involves stacking the wood in rows with gaps between the rows and covering the top of the pile to protect it from rain and snow.
• Wood Species and Drying Times: Different wood species dry at different rates. Softwoods like pine and fir dry faster than hardwoods like oak and maple.

Factors to Consider When Choosing a Tarp

Choosing the right tarp for your wood pile depends on several factors:

• Size of Your Wood Pile: This seems obvious, but accurately measuring your wood pile is crucial. You need a tarp that’s large enough to completely cover the top and ideally extend down the sides a bit.
• Climate: If you live in an area with heavy rainfall or snowfall, you’ll need a more durable and waterproof tarp than someone in a drier climate.
• Durability: The tarp should be able to withstand wind, sun, and abrasion. Look for tarps made from durable materials with reinforced edges and grommets.
• Material: Tarps are typically made from polyethylene, vinyl, or canvas. Each material has its own advantages and disadvantages, which we’ll discuss in detail below.
• UV Resistance: Prolonged exposure to sunlight can degrade tarps over time. Look for tarps with UV inhibitors to extend their lifespan.
• Budget: Tarps range in price from inexpensive polyethylene tarps to more expensive and durable vinyl or canvas tarps. Consider your budget and how long you expect the tarp to last.

Types of Tarp Materials

Let’s take a closer look at the different types of tarp materials:

• Polyethylene (Poly) Tarps: These are the most common and affordable type of tarp. They’re lightweight, waterproof, and available in a variety of colors and thicknesses. However, they’re not as durable as other materials and can tear easily, especially in windy conditions. They also degrade faster under UV exposure. I’ve used poly tarps extensively, especially for temporary coverage, but I always know they won’t last more than a season or two.
  • Pros: Inexpensive, lightweight, waterproof
  • Cons: Not very durable, tears easily, degrades under UV exposure
  • Best For: Short-term use, temporary coverage, budget-conscious users
• Vinyl Tarps: Vinyl tarps are more durable and waterproof than poly tarps. They’re also more resistant to abrasion and tearing. However, they’re heavier and more expensive. Vinyl tarps are a good choice for long-term protection in harsh climates. I used a heavy-duty vinyl tarp to cover a large wood pile at a remote logging site, and it held up remarkably well against heavy snow and strong winds.
  • Pros: Very durable, waterproof, resistant to abrasion
  • Cons: Heavy, more expensive
  • Best For: Long-term use, harsh climates, heavy-duty protection
• Canvas Tarps: Canvas tarps are made from woven cotton or synthetic fibers. They’re breathable, which allows moisture to escape and prevents condensation buildup under the tarp. However, they’re not as waterproof as poly or vinyl tarps and require regular treatment with a water-repellent sealant. Canvas tarps are a good choice for protecting wood piles in areas with good ventilation. My grandfather always used canvas tarps for his firewood, claiming they allowed the wood to “breathe” and dry better.
  • Pros: Breathable, allows moisture to escape
  • Cons: Not as waterproof, requires regular treatment
  • Best For: Areas with good ventilation, users who prefer natural materials
• Mesh Tarps: While not ideal for complete weather protection, mesh tarps are excellent for promoting airflow around the woodpile. They prevent debris from accumulating while allowing for quicker drying. I use mesh tarps often as a base layer under the wood pile to prevent ground moisture from wicking up.
  • Pros: Excellent airflow, prevents debris accumulation
  • Cons: Not waterproof
  • Best For: Base layer, promoting airflow in drier climates

Step-by-Step Guide to Covering Your Wood Pile

Now that you’ve chosen the right tarp, here’s a step-by-step guide to properly covering your wood pile:

1. Prepare the Ground: Clear the area where you’ll be stacking your firewood. Remove any vegetation, rocks, or debris that could damage the tarp or prevent proper drainage. I often lay down a layer of gravel to improve drainage and prevent mud buildup.
2. Build a Base: Elevate the wood pile off the ground to allow for air circulation and prevent moisture from wicking up from the ground. You can use pallets, scrap wood, or even large rocks to create a base. I’ve also used old tires, which work surprisingly well.
3. Stack the Firewood: Stack the firewood in rows, leaving gaps between the rows for air circulation. A common method is to stack the wood in a crisscross pattern, which creates a stable and well-ventilated pile. I prefer a modified Holzhaufen (German for “wood heap”) method, which involves stacking the wood in a circular pile with a central chimney for ventilation. This method is particularly effective for drying wood quickly.
4. Cover the Top: Drape the tarp over the top of the wood pile, ensuring that it completely covers the top and extends down the sides. Secure the tarp with ropes, bungee cords, or tarp clips. Make sure the tarp is taut and doesn’t sag, which can create pockets for water to collect.
5. Secure the Sides: Secure the sides of the tarp to prevent wind from blowing it off. You can use stakes, weights, or tie the tarp to nearby trees or structures. I often use old tires filled with rocks as weights.
6. Check Regularly: Inspect the tarp regularly for tears or damage. Repair any damage promptly to prevent moisture from entering the wood pile.
7. Ventilation: While the top needs to be covered, ensuring good ventilation is key. Leave the sides partially open, especially in drier weather, to allow air to circulate.

Innovative Covering Methods

Beyond traditional tarping, here are a few innovative methods I’ve used to protect my firewood:

• Pallet Shelters: Construct a simple shelter using pallets as walls and a tarp as a roof. This provides excellent protection from the elements and allows for good ventilation. I once built a pallet shelter for a community firewood project, and it was a huge success.
• Repurposed Shipping Containers: Shipping containers can be repurposed as firewood storage units. They’re weatherproof, secure, and provide ample space for storing large quantities of firewood. While expensive, they offer a long-term solution.
• DIY Wood Shed: Building a small wood shed is a more permanent solution for protecting your firewood. A simple shed with a roof and open sides provides excellent protection from the elements while allowing for good ventilation.

Case Study: Drying Oak Firewood in a Humid Climate

I once undertook a project to dry a large quantity of oak firewood in a particularly humid climate. Oak is notoriously slow to dry, and the high humidity made the task even more challenging. Here’s how I tackled it:

1. Wood Selection: I selected oak logs that had been felled during the winter months, as they tend to have a lower initial moisture content.
2. Bucking and Splitting: I bucked the logs into 16-inch lengths and split them into manageable pieces using a hydraulic log splitter. I used a 27-ton splitter, which made the job much easier.
3. Stacking: I stacked the firewood in a modified Holzhaufen pattern, creating a circular pile with a central chimney for ventilation.
4. Covering: I used a heavy-duty vinyl tarp to cover the top of the pile, securing it with ropes and weights. I left the sides partially open to allow for air circulation.
5. Monitoring: I monitored the moisture content of the wood regularly using a moisture meter.
6. Results: After 18 months, the moisture content of the wood had dropped to below 20%, making it suitable for burning. The key to success was the combination of proper stacking, a durable tarp, and regular monitoring.

Safety Considerations

• Wear appropriate safety gear: When handling firewood, wear gloves, safety glasses, and sturdy boots.
• Use caution when lifting heavy objects: Lift with your legs, not your back.
• Be aware of your surroundings: Watch out for uneven terrain, slippery surfaces, and overhead hazards.
• Use caution when using power tools: Follow the manufacturer’s instructions and wear appropriate safety gear. I always wear hearing protection when using a chainsaw or log splitter.
• Store firewood away from your home: Store firewood at least 30 feet away from your home to prevent insect infestations and reduce the risk of fire.

Strategic Insights

Beyond the practical steps, here are a few strategic insights I’ve gained over the years:

• Plan Ahead: Don’t wait until the last minute to prepare your firewood. Start the seasoning process well in advance of the heating season.
• Invest in Quality Tools: Investing in quality tools, such as a good chainsaw, log splitter, and moisture meter, will save you time and effort in the long run.
• Learn from Others: Talk to experienced firewood users and learn from their mistakes and successes.
• Adapt to Your Environment: The best methods for protecting your firewood will vary depending on your climate and location. Be prepared to adapt your approach as needed.
• Consider a Wood Moisture Meter: I can’t stress this enough. Knowing the moisture content of your wood is crucial for efficient and safe burning.

Cost-Benefit Analysis

While a good tarp represents an upfront cost, consider the long-term benefits:

• Reduced Wood Rot: Preventing rot saves you from replacing unusable wood.
• Improved Burning Efficiency: Drier wood burns hotter, requiring less wood overall to heat your home.
• Reduced Chimney Maintenance: Less creosote buildup means fewer chimney cleanings and a reduced risk of chimney fires.

In my experience, the cost of a quality tarp is easily offset by these benefits within a few seasons.
