Steps On How To Waterproof Your Shed

Waterproofing your shed is essential to protect its contents and ensure it stays in excellent condition throughout its lifespan. Your shed is a large investment and often holds valuable equipment, so preventing moisture from getting inside is a must. Here are a few steps on how to waterproof your shed:

Table of Contents


A good foundation is recommended to keep water out. A concrete slab provides a solid and level base for your shed. The higher part of the slab provides the floor of the shed while the walls sit on the lower ‘rebated’ edge of the slab. You can then seal around the inside of the base to provide extra waterproofing protection.


Condensation can occur when the inside of your shed is warmer than outside. Moisture gets trapped when it reaches cooler parts of the shed, often the windows or roof, then condenses and drips onto the floor. Insulation can prevent trapped moisture, and there are many options available to suit all kinds of sheds in Perth.

Shed Location

Before constructing your shed, choosing the best location is an important step to protect it from moisture. Certain areas that are prone to water pooling such as low-lying areas, should be avoided. A location that gets a good amount of sun and is fairly level is a good position to help with waterproofing your shed.


Appropriate drainage for your shed is essential to direct rainwater away from the structure. A drainage system will prevent water pooling or moisture accumulating that could eventually damage the shed and possibly the contents inside.


Sealing all gaps and spaces is a great way to prevent wind and rain from getting inside your shed. Be sure to seal all gaps including around the concrete slab. Sealing your shed not only prevents moisture from entering your shed, it’s a great way to keep vermin out as well.

How Do You Seal Your Shed?

The doors and windows of your shed are important areas to seal. Check for any leaks in these areas and then seal any that you find with caulk. Silicon-based caulk is recommended due to its flexibility. As well as the windows and doors, you should also seal other gaps such as corner joints. These areas may allow rainwater to enter. You may also need to check air vents and joints in the walls and ceiling.

Why is Waterproofing Your Shed Important?

Water can lead to a lot of damage if it’s allowed to get inside your shed. Not only could it harm the structure and the contents inside, it can lead to mould if left unchecked. If your shed contains wood it’s particularly important to waterproof, as wood is very susceptible to water damage.

Waterproofing your shed may seem like a time consuming task; however, it will help to prolong the life of your shed and protect your valuable items stored inside. So in the long run it will save time and money. For more information about sheds in Perth, or to obtain an obligation free quote contact our helpful team at Spinifex Sheds.
