At SJ Waterproofing, we’ve been helping Auckland-based builders and foundation experts with their waterproofing needs for over fifteen years. We specialise in all structural waterproofing works. Most of our clients use us with new builds.

When you choose SJ Waterproofing as your subtrade, you can relax knowing that our workmanship will be excellent and comply with all elements of the Building Code. Plus, we get it done right the first time to protect your project from avoidable problems down the track.

Support and confidence in the products

During construction, we ensure that our work complies with the conditions set out in the building consent and will pass Council’s inspection. Your clients will get a finish that’s not only fit-for-purpose but safe and long-lasting.

Our work is guaranteed for all new jobs, with full product warranties for up to 20 years.

Quick, honest, and regular communication

We won’t leave you in the dark. We will respond to your queries fast – you won’t need to chase us. If we slip up – it doesn’t happen often – we’ll own it and get it sorted. Plus, you’ll know exactly where we are at and when we expect to finish, so you can factor this into your build schedule and communication with your clients.

Leave us to handle the necessary admin and communication to make your job as builder or site manager much easier.

Get it done right the first time

We turn up when we say we will, deliver great attention to detail, and keep the build moving. No-one wants to redo the foundations or their hard work – that won’t happen when you choose us.

What’s more, our fully-trained and experienced team use council-approved, BRANZ-certified products to deliver the best possible waterproofing solutions.

We access the best materials

We can always access the right materials for your client’s specific needs and are approved to use a range of high-quality products from the following suppliers. Our pricing is competitive, too.

Staff and client safety is non-negotiable

That’s why our applicators know what they’re doing and always comply with the Health and Safety at Work Act 2015.
