How Do You Build a Shed Base?

If you’re considering buying a shed and you’re doing your research, you’ve probably seen a lot of information about whether or not you need a shed base. What is a shed base, though, and why do you need one? What’s the best base for a shed? Can’t you just put a shed directly on the ground? That seems way easier, but it’s not the best way. 

Having a base for your shed is really important for long-term durability and the stability of your shed. There are different types of bases, though. The type depends a lot on various things like the location of your shed, the size and how you plan to use it.



Types of Shed Bases (and How to Choose the Right One)

To start, what are the various types of shed bases? How do you choose the right one? Let’s take a look at each type to get a better idea of what you need to do for your shed.

Plastic Grid System Shed Base

This type of shed base is one that you see less often, but it’s still a good option. Here are the pros and cons of plastic grid system shed bases.



• They’re lightweight and modular. This makes them much easier to put together than something heavy like pavers or wood.
• Plastic grid system bases also offer great drainage, which is really important around a shed base.
• They’re often eco-friendly since they’re made from recycled materials! So, this can be better than wood or concrete.
• You can lay this base type down on gravel, sand or even sometimes on grass or soil. It really depends on your yard and the recommendations of the manufacturer of your shed base.
• The plastic grid is not as durable as other options, though, and has a limited load capacity. So, it’s not a great option for larger sheds.
• It’s pricier than a lot of the other shed base options. So, be prepared for that.
• It also requires you to level and prep the ground before using it, which can take more time and money.

Each shed base type has some big pros and cons. So, make sure you weigh your options before choosing the base for your shed.

Step-by-Step Guide for How to Build a Shed Base

Alright, now that we’ve talked about the shed base types, let’s talk about how to build a shed base. These are very general instructions because your exact step-by-step process will depend on the type of shed base you choose to use.



Step 1 – Choose the Right Location

The first and arguably one of the most important steps is to choose where you’re going to place your shed. You’ll want to level the ground, check drainage and also look at your property lines to make sure you aren’t building on someone else’s land. You also might need to look into local HOA rules and building laws in your area. 

No one wants to spend a bunch of time and money to build a shed just to get fined by the HOA or city.

Step 2 – Pick the Best Type of Shed Base

The next step is to choose your base type. We outlined a few options above. Here is a quick list as a reminder:

• Gravel shed base
• Concrete shed base
• Paver shed base
• Timber frame base
• Plastic grid system shed base

You need to decide whether you’re looking for a more permanent shed base, like concrete, or if you’re looking for a floating shed foundation, like gravel. They both have their pros and cons. Just make sure you know which type suits your needs better.

Step 3 – Measure and Mark the Area

Next, you’ll want to measure and mark the area for your shed base. You’ll need a tape measure, stakes, string and spray paint. Make sure you allow for extra space around the shed footprint. Also, don’t forget the old saying to measure twice and cut once. Though you aren’t cutting anything in every one of these instances, the idea of measuring twice before doing anything is still great advice!

Step 4 – Excavate and Level the Ground

For most shed base types, you’ll need level ground. So, depending on the base type you choose, you might need to excavate and level. It’s so important for it to be level and to have the ground compacted for the durability of your shed. If the base isn’t level, it can make building your shed more difficult, cause structural problems and more. It’s a headache, and not worth it. So, make sure it’s level. If you don’t know how to do this, it might be good to consult a professional.

Step 5 – Build the Shed Base

You’ll need to build your base. This process will vary depending on the base type you choose. However, if you’re doing a DIY shed base and you don’t have a lot of experience, your best bet is to find a YouTube tutorial or two. Watch those so you can get an idea of how to lay your shed base correctly. 

Once your base is completed, you’ll have a solid foundation to build your shed.

Common Mistakes to Avoid When Learning How to Build a Base for a Shed

When it comes to shed bases, we’ve talked a little bit about the importance of choosing the right base for your situation. However, sometimes when we’re doing something new (like building a shed base for the first time), we might overlook a few things. Here are a few common issues you need to be mindful of when choosing and building your shed base:

• Skipping drainage planning
• Choosing the wrong base for your soil or shed size
• Not compacting gravel properly
• Forgetting to check for level ground

These things might not seem like a big deal, but they can cause huge issues down the road. It’s better to just address them right away so that your shed can have a strong, durable base that lasts.

Hopefully, this has helped a bit with your shed base project. We wish you the best of luck in carefully picking the perfect base for your next shed.
