💦 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.

**Waterproofing with CIW (NSW) 💪💧**

We don’t just lay membranes — we make sure they’re done right!

From laying the membrane and pasting those laps to terminating the piles & spears like champions 🏆, we take pride in every detail of our work.

Because when it comes to waterproofing, **“she’ll be right” isn’t a waterproofing method!** 😂

Quality workmanship, attention to detail and a job we’re proud to put our name on.

🚧 Another project underway! 🚧

Every masterpiece starts with a blank canvas... ours just happens to need waterproofing first! 😄💧

We're excited to kick off another project and turn this empty space into a finished result built to last.

The team is on site, the work has begun, and we're looking forward to showing you the transformation along the way.

Stay tuned for progress photos—we promise it won't stay this empty for long! 👷‍♂️🔨

Keeping water out and the project moving. 💪🏗️

The CIW boys laying Bentonite membrane for a tower crane foundation in Sydney. Not the flashiest job on site, but one of the most important.

Another waterproofing job wrapped up — and this basement is now completely dry and ready ..

There’s nothing better than handing over a project knowing the client can finally use their space without buckets, leaks, or that mysterious damp smell making an unwanted appearance.

This is what can be achieved when you deliver a *dry basement* to the client:
✔️ Peace of mind
✔️ A usable space again
✔️ Long-term protection for the property
✔️ One very happy customer



Proud of the team for another quality result from start to finish. Waterproofing done properly makes all the difference.

Coming up to 12 years this October with Complete Injection & Waterproofing… wow. They say you get less for murder 😂

But in all seriousness, it’s been a wild ride—juggling all the hats, keeping things running behind the scenes, and somehow still loving the chaos.

Here’s to the laughs, the fun days and doing whatever it takes to get the job done 💪

No, you’re not seeing double… but their mum might be seeing trouble 👀😂

The Brother boys are back at it, rolling out one of our bentonite membranes and getting the job done properly (and causing just a little bit of mischief along the way).

All jokes aside—this is how we keep things watertight and built to last. Quality materials, solid teamwork, and a crew that knows how to have a laugh while getting it done 💪

Hard work doesn’t come with an age limit 💪

Shoutout to one of our young legends on the team who’s been absolutely smashing it on-site lately. Always showing up, putting in 100%, and proving that a strong work ethic goes a long way in this game.

We’re all about quality waterproofing—and that starts with quality people. Safe to say the future of the trade is looking pretty solid 👷‍♂️
