When you are looking to set up a shed, you will assume a strong base is enough to keep it dry.
This does not always work out as you want it to.
The shed might start leaking and that is going to create real concerns about how long it lasts. It will start decaying and that is not a good sign.
This is why you will want to pinpoint what is going on for a shed to start leaking from the bottom.
If the shed is leaking at the bottom, it is likely due to rain erosion and moisture seeping through the base. To fix the issue, check for gaps in the base, build a small trench near the bottom to funnel water away, build a border along the base, or use gutters to push water away from the shed.
You will have a few options to work with.
It is important to think about the layout of the shed and where the water is coming from. This tends to happen a lot with sheds that are set up at the bottom of a hill or slope.
This guide is going to show you what to do if a shed is leaking at the bottom.

How To Fix A Shed Leaking At The Bottom
1. Check For Gaps In The Base
You will want to start by checking for gaps in the base.
The real issue tends to come when moisture continues leaking through the bottom and then opens up cracks in the shed’s exterior.
This is not a good sign as the water is going to continue to flow through the same spot. Plus, those gaps are going to widen further. It is not going to stop.
This is why you will want to spot where the water is coming from. You should be aware of the water’s path before working on a solution. It is the only way to stop the leaking.
2. Build A Small Trench To Funnel The Water
If the metal shed has a leaking floor, you might need to think about building a small trench around the base of the shed.
Why does this work?
The premise is to have a way for the water to go. You don’t want the water to puddle around the base of the shed as that is eventually going to lead to major moisture issues.
It is best to have a way to funnel the water away.
This is where the small trench is going to come in handy.
Look into this as you are trying to push water away from the shed.
3. Build Border Along The Base
When learning how to waterproof a shed base, you will want to think about building a border along its base.
Why is this going to work?
The premise is to have a way to immediately stop the moisture from leaking into the shed. This is where the wall is going to come in handy.
The wall is going to act as a complete block against the water. If you set it up at the right angle and make sure it is robust, the shed will remain safe.
It will take a bit of time to create but you just have to angle it in a way where the water does not continue to leak through the bottom of the shed.
4. Consider Using Gutters For The Base
You can also take the time to think about setting up gutters for the shed’s base.
This is a good way to waterproof the shed base.
The idea behind gutters is to get the water to collect in them and then move to the drain nearby. You don’t want the water to have anywhere to go as that is how you will end up dealing with large puddles around the shed.
The water needs to go somewhere or the shed is going to be in bad shape right away.
Do not wait around for this to happen. If you know moisture is a problem, you will want to set up the gutters as soon as you can for the shed.
These are the reasons your shed is leaking at the bottom.
If the shed is leaking at the bottom, it’s best to find where the water is coming from and then build a small trench near the base to funnel water away. Another solution is to set up gutters to collect the water and then move it toward a nearby drain.
You will want to work on pinpointing what works for getting the water away from the shed.
Each shed is different including how it is set up. You will want to account for this and then pinpoint a plan that is going to work to waterproof the shed’s base.
