💧 When Water Gets Where It Shouldn’t… We Get Called In! 😎
Think waterproofing is just “slap some stuff on the wall and hope for the best”?

Think again. 😂

At Complete Injection & Waterproofing, we get right into the problem — literally.

This diagram gives you an idea of what goes on behind the scenes when we’re dealing with water ingress, wall voids, cracks and sub-slab issues.

🛠️ Multi-point injection & grout distribution
🔍 And plenty of know-how to work out where that sneaky water is coming from!

We don’t just treat the symptom and cross our fingers. We use specialist injection techniques to get material where it needs to go and tackle waterproofing problems at the source.

Basically… if water has found a way in, we’re pretty good at showing it the way out. 😂💦

ON TOP OF THE WORLD! 🌎

Well… not quite.

Turns out I’m actually standing on top of our bentonite waterproofing membrane! 😂

So yes… technically, I’m standing on a very important part of the building envelope. 😎💧

Just don’t tell the bosses I was enjoying the view from the top! 🤣

Professional waterproofing.
Serious protection.
Occasionally questionable photo opportunities. 😂

🦺 New Workwear Has Arrived!

The NSW Team is officially getting a fresh new look! 👕🦺

The new Complete Injection & Waterproofing hi-vis shirts have arrived and are ready for action.

Now there’s just one small job left…

Getting these handsome men into them! 😂

Because looking good on site is obviously just as important as delivering quality workmanship… right? 😉

Jokes aside, we’re proud to keep building a strong, professional team across NSW — and making sure our crews look the part while they get the job done.

New shirts. Same great team!

Now to be a good pic of the NSW Team in them .. I'll keep you posted!

Waterproofing a basement 🌊

Here are some work-in-progress photos from a challenging two-level basement project on the Gold Coast — located just 1.5m away from the Nerang River and approximately 4.0m below river level.

For this project, our Neoferma waterproofing system was selected to provide robust protection against water ingress and the demanding conditions associated with a high water table and proximity to saltwater.

The system included:

1,500m² of Neoferma Swellseal MS ultra-contaminant-resistant waterproofing membrane
Neoferma X-Seal Inject reinjectable hose system, allowing for future remedial injection using Neoferma ACRYL-X® Gel
Neoferma Jointstop S, a saltwater-grade waterstop system for critical construction joints

Projects like this highlight the importance of selecting a waterproofing system that not only addresses the immediate construction conditions, but also provides long-term resilience and the ability to manage potential water ingress well into the future.

Great to see our products being put to work on such a technically demanding project on the Gold Coast.

💦 WATER IN THE LIFT PIT? NOT ON OUR WATCH! 😂

The boys from Complete Injection & Waterproofing – CIW (NSW) have been getting stuck into another lift pit injection project. 💪🏗️

When water decides it wants to make an unwanted entrance, the CIW crew knows exactly how to show it the door! 🚪💧😂

Another solid effort from the boys, with quality workmanship, attention to detail and a job done properly — because when it comes to waterproofing, “she’ll be right” isn’t part of our method statement! 😎

Big job. Hard work. Great result. 👏🔥

💦 Another great job by the team at CIW(NSW)! 💦

Membrane and waterstops going down in Forster, and the boys are getting it done! 💪

A big thanks to the Builder for putting in the work and getting the ground prepped textbook standard. 👌

When the preparation is spot on, it makes the installation process smooth, efficient and helps our team deliver the quality finish we’re known for.

Great work by everyone involved! 🔥

💦 Built to Keep Sydney Dry

The boys at Complete Injection & Waterproofing are back at it — applying bentonite membrane to perimeter walls like it’s just another day at the office. 😎

When it comes to membranes & waterstops, we like to think we’re pretty good at what we do… actually, Sydney’s top installers sounds better. 😉

From getting the membrane perfectly installed to making sure those waterstops are doing their job, our crew takes waterproofing seriously — because nobody wants their basement becoming Sydney’s newest indoor swimming pool. 🏊‍♂️😂

Quality workmanship. Proper installation. No shortcuts.
