When you think about sleek, polished concrete floors, your mind probably jumps to how shiny and stylish they look. And sure, we love a good shine here at NZ Grinders. But there’s a lot more going on under the surface (literally) that makes those floors both durable and beautiful. One of the most important, yet often overlooked aspects of natural stone grinding is concrete expansion and control joints.

Yep, we said it—joints! Stick with us, though, because it’s about to get interesting.

What’s the Deal with Natural Stone Grinding?

Natural stone grinding might sound like something from an ancient quarry, but it’s actually one of the modern tricks up our sleeves here at NZ Grinders. Stone grinding is how we take your stone surfaces—normally concrete—down a few notches (literally) to create a smooth, level, and flawless surface. Whether you’re dealing with unevenness or stains from years of wear and tear, natural stone grinding gets the job done.

Now, if you’re located anywhere in the North Island, from Auckland to Tauranga or even down in Wellington, you’re in luck. We offer this service to give your floors a new lease on life. And when you have a polished concrete, your floors won’t just look good—they’ll feel like you could serve dinner on them (we don’t recommend that, though).

Expansion and Control Joints: The Silent Protectors

Alright, let’s talk about expansion and control joints. It may not sound thrilling, but if you want a concrete floor that doesn’t crack faster than your old smartphone screen, you’ll need these.

Concrete is like the Hulk of building materials—it expands and contracts depending on temperature and moisture. Without expansion and control joints, your concrete slabs could buckle under the pressure. And trust us, that’s not a pretty sight. Expansion joints allow the slabs to flex and move without causing damage. Control joints, on the other hand, manage cracking—so when it happens, it’s in a controlled, tidy way.

At NZ Grinders, we take these joints seriously. Whether you’re after a full stone exposure polished concrete in Rotorua or grinding it down in Napier, we make sure the joints are exactly where they need to be. That way, your floor stays looking fresh and crack-free, no matter how many summers and winters it goes through.

Then, we go in with our concrete polishing wizardry to make the floor look like it belongs in an art gallery.
