10 Ideas On How to Waterproof a Wall Below Ground Level

1. Use a Waterproof Membrane

2. Use Cementitious Waterproofing

Cementitious waterproofing is another great way to waterproof a wall below ground level. This involves applying a cementitious waterproofing material to the wall and then coating it with a sealant to help keep water out.

3. Apply Elastomeric Coating

Elastomeric coatings are liquid rubber-based materials that can act as a barrier against water seeping through walls below ground level. It’s important to use an appropriate elastomeric coating for your wall: some are designed for interior walls while others work better on exterior walls.

4. Install a Drainage System

If you have an area beneath your wall where water can pool, it’s essential to install a drainage system, such as a French drain or sump pump. This will help to draw water away from the wall and prevent it from seeping in.

5. Install Gutters & Downspouts

Gutters and downspouts are an important part of waterproofing a wall below ground level because they divert rainwater away from the foundation instead of allowing it to pool around the walls. Make sure to clean your gutters regularly and check for any signs of damage.

6. Use a Waterproof Paint

Using waterproof paint is an easy way to protect your walls below ground level from water damage. There are various types of waterproof paints available; make sure you select one that’s suitable for external use so it won’t be affected by rain and other elements.

7. Seal Cracks & Joints

It’s important to seal any cracks or joints in your wall before attempting to waterproof it because these can allow water to seep through into the foundation. Use a waterproof sealant designed for external use, such as an asphalt-based mastic compound or a polyurethane sealant.

8. Install a Moisture Barrier

Installing a moisture barrier is an effective way to waterproof your wall below ground level. This involves attaching a layer of waterproof material, like plastic or rubber sheeting, over the walls and sealing it with a heavy-duty adhesive.

9. Add Drainage Mats

Another way to waterproof your wall is to install drainage mats, either on the interior or exterior of the wall. These mats are made up of a series of channels that allow water to be diverted away from the foundation.

10. Re-grade Your Landscaping

Sometimes it’s necessary to re-grade your landscaping around the foundation in order to provide proper drainage away from the walls. Make sure to slope the soil downhill and away from your home’s foundation and install gutters or divert water to a nearby drain if necessary.

Following these steps will help ensure that your wall is properly protected against water damage. These are just some of the ways you can waterproof a wall below ground level. 

If you’re unsure of which method to use or need help with the installation process, it’s best to contact a qualified professional. A professional will be able to provide advice on the most effective way to waterproof your wall and ensure it is done correctly for maximum protection.
