Building a Foundation for a Shed on Skids: Wood Processing Tips for Durability and Cost-Effective Budgeting

Understanding the User Intent: What are We Trying to Achieve?

The user intent behind searching for “Foundation for Shed on Skids (Wood Processing Tips for Durability)” boils down to these key needs:

• Construction Guidance: How to physically build a skid foundation suitable for a shed.
• Durability Focus: Strategies and materials to ensure the foundation can withstand the weight and vibration of wood processing equipment.
• Cost Optimization: Practical tips and budgeting advice to keep the project affordable without compromising quality.

Choosing the Right Skid Material: A Deep Dive into Wood Species

The choice of wood for your skids is crucial for long-term durability. The wood needs to resist rot, insect infestation, and the constant pressure of the shed’s weight, especially when loaded with heavy wood processing equipment.

• Pressure-Treated Lumber: This is the most common and often the best choice. Pressure treatment infuses the wood with chemicals that deter insects and decay. Look for lumber rated for ground contact. I’ve used pressure-treated 6×6 timbers for several sheds, and they’ve held up remarkably well, even in damp environments.
• Naturally Rot-Resistant Wood: Some wood species have natural oils and compounds that make them resistant to decay. Redwood, cedar, and black locust are excellent choices, but they often come with a higher price tag. In my experience, cedar is a good middle ground – it’s more affordable than redwood but still offers excellent rot resistance.

• Wood Species Comparison:

  Wood Species	Cost (Relative)	Rot Resistance	Insect Resistance	Strength	Notes
  Pressure-Treated Pine	Low	Excellent	Excellent	Moderate	Most cost-effective; ensure ground contact rating.
  Cedar	Moderate	Good	Good	Moderate	Aromatic; naturally resistant.
  Redwood	High	Excellent	Excellent	Moderate	Beautiful; excellent performance but pricey.
  Black Locust	High	Excellent	Excellent	High	Very strong and durable; often used for fence posts.
  Untreated Pine	Low	Poor	Poor	Moderate	Not recommended for skids due to rapid decay.
  Oak	Moderate	Moderate	Moderate	High	Can be used if properly sealed; prone to rot if in constant contact.

• My Personal Experience: I once tried using untreated oak for skids, thinking its strength would compensate for the lack of treatment. Big mistake! Within a couple of years, the oak started to rot where it contacted the ground, and I had to replace the entire foundation. Lesson learned: always prioritize rot resistance.

Skid Size and Spacing: Engineering for Load Distribution

The size and spacing of your skids directly impact the shed’s stability and its ability to handle the weight of your wood processing equipment.

• Skid Size: 6×6 timbers are generally recommended for sheds up to 12 feet wide. For larger sheds or those housing heavy equipment, consider 8×8 timbers. The larger the timber, the greater its load-bearing capacity.
• Skid Spacing: A good rule of thumb is to space skids no more than 4 feet apart. For heavier loads, reduce the spacing to 3 feet or even 2 feet. Proper spacing prevents the floor from sagging between the skids.

• Calculating Load Distribution: To determine the appropriate skid size and spacing, you need to estimate the total weight the shed will bear. This includes the weight of the shed itself, the weight of your wood processing equipment, and the weight of any stored wood.

  • Formula: Total Weight = Shed Weight + Equipment Weight + Wood Weight
  • Example: Let’s say your shed weighs 2,000 lbs, your equipment weighs 1,500 lbs, and you plan to store 500 lbs of wood. The total weight is 4,000 lbs.
  • Distribution: If you use three skids, each skid needs to support approximately 1,333 lbs. Check the load-bearing capacity of your chosen wood species and size to ensure it can handle this weight. You can usually find this information from your lumber supplier or online resources.

• Case Study: I designed a shed for a local woodworker who had a heavy-duty lathe and a bandsaw. To ensure the foundation could handle the weight, I used 8×8 pressure-treated timbers spaced 2.5 feet apart. I also added extra support under the lathe to prevent any sagging. The shed has been in use for five years now, and the foundation is still rock solid.

Preparing the Ground: Creating a Stable Base

A level and well-prepared ground surface is essential for a stable shed foundation. Even the strongest skids will sink or shift if the ground underneath is uneven or soft.

• Clearing and Leveling: Remove all vegetation, rocks, and debris from the area where the shed will sit. Use a shovel and a level to create a flat and even surface. This might involve digging down in some areas and filling in others.
• Gravel Base: A layer of gravel provides excellent drainage and helps to distribute the weight of the shed. Spread a 4-6 inch layer of gravel over the leveled area and compact it with a tamper or a plate compactor. I always recommend using crushed gravel, as it interlocks better than round gravel and provides a more stable base.
• Weed Barrier: Laying down a weed barrier fabric under the gravel will prevent weeds from growing up through the foundation. This will save you time and effort in the long run.
• Ground Contact Considerations: If the skids will be in direct contact with the ground, ensure the soil is well-draining. Poor drainage can lead to accelerated rot, even with pressure-treated lumber. In areas with heavy clay soil, consider adding a layer of sand under the gravel to improve drainage.
• Data Point: According to a study by the University of Minnesota Extension, proper site preparation can extend the lifespan of a wooden structure by up to 50%.

Construction Techniques: Building a Solid Skid Foundation

Now that you have your materials and a prepared site, it’s time to build the skid foundation.

• Cutting the Skids: Cut the skids to the desired length. Ensure they are all the same length to maintain a level foundation. Use a circular saw or a chainsaw for cutting the timbers. Remember to wear appropriate safety gear, including eye protection and hearing protection.
• Treating Cut Ends: When you cut pressure-treated lumber, you expose the untreated wood inside. Apply a wood preservative to the cut ends to prevent rot. This is a small step that can significantly extend the lifespan of your foundation.
• Assembling the Frame: The skids form the base of the foundation. You’ll need to build a frame on top of the skids to support the shed floor. This frame is typically made of 2×6 or 2×8 lumber.
• Fastening the Frame to the Skids: Use galvanized lag bolts or construction screws to attach the frame to the skids. Space the fasteners every 12-16 inches. Ensure the fasteners are long enough to penetrate deep into the skids.
• Adding Floor Joists: Install floor joists between the frame members to provide additional support for the floor. Space the joists 16 inches on center for standard loads or 12 inches on center for heavier loads. Use galvanized joist hangers to attach the joists to the frame.
• Sheathing the Floor: Cover the floor joists with plywood or oriented strand board (OSB) sheathing. Use construction screws to fasten the sheathing to the joists. Ensure the sheathing is rated for exterior use.
• Leveling the Foundation: Once the foundation is complete, use a level to check for any unevenness. Shim the skids as needed to create a perfectly level surface. This is crucial for the stability of the shed.
• Pro Tip: I like to use a laser level for this step. It makes it much easier to get the foundation perfectly level, especially for larger sheds.

Wood Processing Equipment Considerations: Reinforcing for Heavy Loads

If you plan to use the shed for wood processing, you’ll need to reinforce the foundation to handle the weight and vibration of your equipment.

• Identifying Load Points: Determine where your heavy equipment will be located in the shed. These areas will require additional support.
• Adding Extra Skids: Consider adding extra skids under the areas where the equipment will be placed. This will distribute the weight more evenly and prevent the floor from sagging.
• Reinforcing the Frame: Use larger lumber for the frame members in the areas where the equipment will be located. Consider using 2×8 or even 2×10 lumber.
• Adding Blocking: Install blocking between the floor joists to provide additional support. Blocking is short pieces of lumber that are installed vertically between the joists.
• Concrete Piers: For extremely heavy equipment, consider pouring concrete piers under the skids. This will provide a solid and stable base that can handle even the heaviest loads.
• Vibration Dampening: Wood processing equipment can generate a lot of vibration. Consider using vibration-dampening pads under the equipment to reduce the amount of vibration that is transmitted to the shed.
• Personal Story: I once built a shed for a woodworker who had a very old and very heavy bandsaw. I knew the standard foundation wouldn’t be strong enough, so I added extra skids, reinforced the frame, and poured concrete piers under the bandsaw. The shed has been in use for over 20 years, and the foundation is still perfectly level.
