Planning & Design: Your Root Cellar Blueprint

Before you start hauling sandbags, careful planning is crucial. The size of your root cellar will depend on your family's needs and the amount of produce you plan to store. For a small family, a 6-foot diameter round structure is often sufficient.

Location, Location, Location!

Choosing the right location is vital for maintaining the ideal temperature and humidity levels within your small root cellar. Consider these factors:

  • Shade: North-facing slopes are ideal as they receive less direct sunlight, keeping the cellar cooler. If a north-facing slope isn't available, find a naturally shaded area or consider planting trees or shrubs to provide shade.
  • Drainage: Avoid areas prone to flooding or with high water tables. Good drainage is essential to prevent moisture problems. If your soil is poorly draining, you may need to install drainage around the cellar.
  • Accessibility: Choose a location that's easily accessible, especially during winter. You don't want to trek through deep snow to retrieve your potatoes!
  • Proximity to the House: While some distance can help maintain cooler temperatures, you don't want it to be too far. A balance between convenience and temperature control is key.

Simple Design:

For this beginner-friendly project, we’ll focus on a dome-shaped earthbag construction. The dome shape provides excellent structural stability and maximizes space. Here's a basic diagram to visualize the structure:

Size Considerations:

A 6-foot diameter compact root cellar will provide ample storage space for a small family's needs. You can always adjust the size based on your specific requirements. Remember, it's better to start small and expand later if needed.

Materials List: Affordable and Sustainable Options

Here's a detailed materials list with estimated costs. Remember to check local sources for the best prices and consider using reclaimed or recycled materials whenever possible to create a cheap root cellar.

  • Polypropylene Sandbags (Burlap also works but deteriorates faster): 200-250 bags ($50 - $75). Source used feed bags from local farms for a cheaper and more sustainable option.
  • Sand or Gravel: Approximately 5-7 cubic yards ($50 - $100). Use locally sourced sand or gravel.
  • Barbed Wire: 2-3 rolls ($30 - $45). This is crucial for adding tensile strength between the earthbag layers.
  • Lime or Cement (for stabilization): 2-3 bags ($20 - $30). Adding lime or cement to the sand mixture increases the durability of the bags.
  • Door: Reclaimed door or build your own from scrap wood ($0 - $50).
  • Vent Pipe (PVC): 4-inch diameter, 10 feet long ($10 - $15).
  • Hardware Cloth (for vent cover): Small piece ($5). To keep out rodents and insects.
  • Wood for Door Frame and Lintels: Reclaimed lumber ($0 - $20).
  • Shovel, Wheelbarrow, Tamper, Level, Measuring Tape, Gloves, Safety Glasses. (These are assumed to be already available)
  • Optional: Waterproofing Material (e.g., plastic sheeting or pond liner): ($20 - $40). For added protection against moisture.

Total Estimated Cost: $185 - $320 (Depending on material choices and availability)

Step-by-Step Construction: Building Your Earthbag Haven

Now for the fun part! Follow these steps to construct your easy root cellar:

Step 1: Site Preparation & Foundation

  • Clear the area of vegetation and debris. Level the ground as much as possible.

  • Mark the outline of your circle (6-foot diameter).
  • Dig a shallow trench (4-6 inches deep) along the marked circle. This will provide a stable base for the first course of earthbags.

Step 2: Filling the Bags

  • Mix your sand or gravel with a small amount of lime or cement (approximately 1 part lime/cement to 10 parts sand/gravel). This will help stabilize the bags and prevent them from breaking down over time.
  • Fill the bags approximately 2/3 full. Overfilling will make them difficult to work with.

  • Compact each bag firmly using a tamper. This is crucial for creating a strong and stable structure.

Potential Pitfall: Don't overfill the bags! It will make them difficult to maneuver and compact properly.

Step 3: Laying the First Course

  • Place the filled bags in the trench, end-to-end, forming a complete circle.

  • Tamp each bag firmly in place, ensuring they are level.
  • Lay a strand of barbed wire on top of the first course. This will act as reinforcement between the layers.

Step 4: Building Subsequent Courses

  • Continue laying courses of earthbags, staggering the joints like bricks. This will increase the structural integrity of the wall.
  • Tamp each bag firmly in place and add a strand of barbed wire between each course.

  • As you build, gradually incline each course inward to create the dome shape.

Potential Pitfall: Maintaining a consistent angle is key to a stable dome. Use a simple guide (like a stick cut to the desired angle) to ensure each course is inclined correctly.

Step 5: Creating the Doorway

  • When you reach the desired height for the doorway, create a lintel using sturdy pieces of wood. This will support the bags above the opening.
  • Continue building around the doorway, ensuring the structure remains stable.
