Do I Need to Waterproof a Retaining Wall?

While it may not seem like such a big deal, waterproofing a retaining wall is very important to prevent water leakage, particularly if you’re in an apartment complex or multi-storey building or even the owner and manager of such a property.

Failing to correctly waterproof a retaining wall – especially a shared retaining wall – could result in more hazardous structural damage to your building than if you’d just taken the necessary precautions of waterproofing in the first place.

How to Waterproof a Retaining Wall

We are experts in knowing how to waterproof a retaining wall. As such, we would highly recommend consulting us before attempting to learn how to waterproof a retaining wall.

However, we understand that some people like to do things themselves, so have compiled the following tips and steps on how to waterproof a retaining wall yourself.

Waterproofing a Retaining Wall Preparation

Knowing how to waterproof a retaining wall is one thing, but knowing how to correctly prepare both yourself and the wall for waterproofing is something else entirely, and often forgotten if you’re attempting to waterproof the wall yourself.

Waterproofing your retaining wall is best done directly after the wall is built, and as such should be prepared prior to construction.

In Australia, building a retaining wall may rely on Council approval, so it’s important to check this before you start, and consult your building plans to be fully aware of where plumbing and pipes are located on your property.

Check Drainage

Checking you have adequate drainage for your retaining wall is a huge part of the construction process, and by extension, the steps you need to take in how to waterproof your retaining wall.

This includes ensuring that your soil levels are correct, your wall has a solid foundation and will function according to your requirements.

Assuming all this is the case, you’re ready for the next step of how to waterproof a retaining wall: the act of waterproofing itself.

Waterproofing Your Retaining Wall

You need to apply a waterproofing membrane to the back of your retaining wall, and ensure that no water (or creepy crawlies) can get into your wall to ruin the foundation. Leave to dry according to the instructions provided by the manufacturer and you’re good to go.

When to Call in the Professionals

While knowing how to waterproof a retaining wall is one thing, actually being able to apply your knowledge is often something entirely different. And there’s no shame in that, particularly in ensuring the safety of your tenants and the integrity of your building.

If waterproofing your retaining wall is beyond your skill set, or you simply want to be 100% certain the job is done effectively and efficiently, contact the experts at Remedial Property Solutions.
