Do I Need Plastic Under Shed? (Answered)

Preparing a shed is one of the most important parts of setting it up.

You will need to account for everything including where the shed is going to go and how you will keep the shed safe.

It is going to be fully exposed outdoors, which means it is important to do things the right way. This includes assessing what you are going to do to keep the shed as safe as possible.

You will want to start by thinking about materials to put under a shed. This includes asking, do I need plastic under the shed?

You do not need plastic under the shed. However, it’s recommended to use a sheet of polyethylene to protect against moisture. It will also help stabilize and insulate the shed, which is essential for long-term durability.

In some conditions, it is unnecessary to have a plastic sheet under the shed. This is a decision you will have to make based on how dry it is in the area where the shed will be set up.

If it does rain a lot, you will need to look at creating a vapor barrier for the shed in the yard.

This article is going to shed some light on the advantages of putting plastic under the shed and why it is a good option.

Benefits Of Plastic Under Shed

1. Protects Against Moisture

Having a ground moisture barrier under the shed is a wonderful idea.

It can be placed under the slab where the shed is going to sit.

The reason this works comes down to protect against moisture in the ground. When there is rain, the moisture content in the soil is going to rise.

This is going to directly impact anything that is sitting on top of it.

Even with a stable base, you will still need to think about having a robust moisture barrier in the way. This is what you are going to get with a plastic sheet under the shed.

It will make it a lot easier to keep the shed safe in wet regions.

2. Helps Insulate The Shed

It is important to think about insulation when it comes to the shed and how it will be kept safe.

Yes, insulation is going to refer to the inside walls of the shed but you also have to think about what plastic in the right spot can do.

The plastic is going to help create a robust bubble around the shed.

This is going to be done by placing it underneath the shed. It will ensure anything that could go wrong from the bottom is going to be out of the way instantly.

This does play a role in keeping a shed safe in the yard and ensuring it lasts as long as you wish for it too.

3. Provides Peace Of Mind

Putting a vapor barrier under the shed is smart as it will provide peace of mind.

A lot of shed owners worry about their shed getting flooded from underneath and/or cracking because moisture seeps in.

These are legitimate concerns and not something to take lightly.

If it does rain a lot in the region, you will want to think about moisture content in the ground under the shed.

While you don’t need to set up a vapor barrier for a shed, it is still going to provide peace of mind. This is not something to underestimate.

This is key as you learn how to protect the underside of a shed floor.

4. Increased Stability

How stable is the shed when it is set up?

You will want to make sure the shed is as stable as you want it to be. This is a real concern when you are setting up the shed and hoping for it to last a long time.

An unstable shed is not going to work out as you want it to.

It will become harder to maintain and it is not going to last. This is why increased stability ties in with a vapor barrier under the shed.

Having the plastic sheet under the shed floor will go a long way in keeping it safe.

Final Thoughts

Do I need plastic under the shed?

You do not need plastic under the shed. However, it is advantageous to consider it as a way to create a vapor barrier underneath the shed. It will also stabilize the shed and make sure it ages better.

This is key for those who want to ensure they are doing everything to protect the shed.

It is not an investment that is always needed in warmer regions but it will do wonders when you are living in a wetter part of the world.

Consider this as you begin setting up a shed in the yard and want to create a protected base for it.
