So, you’re thinking what should go between the ground and the shed?

First thing that you’d need to do is choose the proper foundation. Gravel or concrete are the best permanent options. While plastic and adjustable foundation bases are inexpensive and movable. You can add vinyl, concrete or brick shed skirting to fix the gap between the ground and the foundation.

Do You Really Need Something Between the Ground and Shed?

Yes, a foundation is absolutely necessary for your shed. A base elevates your shed off the surface. If the shed is placed upon a fragile or badly built base, even the most well-designed and robustly assembled sheds won’t have a very long lifespan.

You’ll also need a suitable location for your shed. Having a shed that isn’t level puts pressure on the structure that wasn’t anticipated.

Just give it some thought. Without a foundation, the soil moisture will cause your shed to become wet. It will make the things inside the shed wet.

That is why you would require shed skirting. The space under the floor stops moisture from coming up from the ground. The air flow under the floor will dry the wood.

Best Foundation Types For Your Shed

It’s critical to do your homework before choosing your foundation. We’d highly recommend that you focus your decision on the dimensions and style of the shed you intend to construct.

We have prepared the best types of foundations. Simply select according to your needs!

Option 1- Concrete:

On a completely leveled, exposed surface or a sand base, concrete paver bases are constructed. Pavers or fully concrete foundations provide a sturdy, level base for constructing or installing a shed and smoothly support the floor.

Making a shed base with pavers is cheap. Slabs work well on level terrain for smaller sheds made of steel, wood, or plastic, even without a floor. But you’d need to be careful if you want to make a fully concrete base. The mistakes are permanent but the shed will be indestructible. 

When you use concrete, the entrance should be close to or just on the soil surface. No need to keep a gap as they’re heavy.  It takes a lot of time and effort, but the results will last for several years.

Option 2- Gravel:

This is the runner-up option. You should choose a gravel base for pre-built sheds that already have wooden floors.

For this, only the foundation blocks need to be leveled, not the rest of the land surface. Remember that, leveling the blocks and making the corners square are the hardest steps.

A gravel base wicks away moisture that collects around the shed’s base. As a result, it is appropriate for tropical climates and areas with heavy snowfall.

Option 3- Adjustable Foundation:

Most of the time, foundations really aren’t needed for the tiny sheds. There’s a chance that the shed won’t need any extra support from the landscape design.

With a metal or plastic smoothing jack and a wooden frame, you’d have to use a type of shed leveling kit to make an extendable shed base system.

It is possible to construct the shed on the steep slopes with concrete pavers. This is because the shed feet are adjustable.

Option 4- Plastic Base:

The plastic foundation rests flat on the floor, so finding a level surface is ideal.  Some pvc grid systems might be an acceptable option instead of concrete pavers.

Portable plastic makes grids easy to handle. They can be cut and shaped with a regular hand saw. And, their air cells will prevent moisture buildup in the shed.

You should select the best plastic shed base which is durable, reusable plastic foundation grids. Otherwise, your foundation will rot and may not last as long as you would like.

Best Shed Skirting Options For You

Now, if you’re using adjustable bases that are not flat on the ground but elevated several inches off, you’d have to use shed skirting.  We have listed a few options for you!

Vinyl Shed Skirting:

For a shed skirting, this is one of the most cost-effective and easy-to-install options. You can make it more visually appealing by adding lattice work. However, they are not resistant to rodents and do not last for a long time.


Concrete blocks won’t break down or get moldy. As these materials are quite inflexible, animals will not be able to chew through them like they can with timber or lattice work vinyl.

Dura skirt shed skirting resembles contemporary home’s concrete foundations. This efficient option includes a lot of custom-cut cinder block boards to cover the entryways underneath your shed.

Brick Shed Skirting:

Brick has a timeless aesthetic. However unlike concrete slabs, brick doesn’t stop air from getting underneath the shed base.

You can create openings for air circulation in the brick skirting by building vents into it. In spite of this, the space beneath it will remain impenetrable to rodents and other infestations.

Frequently Asked Questions

Is it OK to use dirt to fill the space beneath my shed?

Answer: Don’t put dirt in the space underneath the shed. The shed’s wood structure or sheathing will quickly rot if wet dirt is allowed to contact it. It creates a soggy, humid space underneath the shed, encouraging mold growth.

Is a concrete base a good option for places with heavy rain?

Answer: No, a concrete base is unsuitable for locations with heavy precipitation. A base made of concrete can’t take in water and won’t dry as quickly as wood or other materials would. During heavy rains, this can lead to additional flowing water issues.

Wrapping Up

Now you know everything about what should you put between ground and shed. You can now go on with your little construction project!

Before you get started, you need to check in with the Building Inspector in your area. If not, you could be fined or forced to remove your work. They will help you with the different types of soil that are found in their region.

Good luck with your project!
