Every plumber should have one. You can’t beat the petrol saw for power and by far the best thing is being able to use the saw inside with no fumes. I’ve been sick many times due to the effects of carbon monoxide but no longer. The amazing added benefits are the cleanliness of cutting with the reduced slurry. The exhaust vacuum is great too for all types of cleanup including drain cleaning.

Our Vision
“A world where every worker who cuts concrete, stone or brick can do so without fear of dying from lung disease.”
At Guarda, we know that every case of occupational silicosis is entirely preventable. With the right controls in place, no one needs to be impacted by this terrible disease. That’s why we developed the world’s most effective silica dust suppression technology for masonry saws.

Our Story
In 2005, our Founder, Steve Terpstra was concerned that he could develop silicosis from wall chasing and concrete cutting.
Ongoing exposure to the hazards of silica dust and to carbon monoxide had left him fearing for his health and that of his employees.
Steve researched all the current market offerings and concluded that they did not adequately suppress silica dust and considered closing his cutting business. Instead, he set about developing his own dust suppression solution, vastly superior anything else in the market. This initial research and development yielded Tri-Vac Technology, the world’s most effective silica dust suppression system that uses water and vacuum to trap dust, turn it to slurry and remove it into a vacuum barrel before it becomes airborne.
Tri-Vac Technology is so effective it can suppress up to 99% more deadly silica dust compared to other systems making workplaces much safer and protecting worker health like no other masonry cutting systems can. This technology is present on Guarda products for sale and in use on all equipment used in Guarda’s wall chasing and concrete cutting service business.
The world’s best silica dust suppression on masonry saws
Guarda have developed a novel and superior solution to suppress silica dust during masonry cutting activities. The use of both water and vacuum allows our solution to deliver up to 99% more suppression of deadly silica dust with the removal of slurry by-products and exhaust fumes.
As seen on Shark Tank
Guarda successfully secured a conditional deal for a $250,000 investment from Robert Herjavec on the Australian series of Shark Tank in July 2024. This is based on the successful conclusion of a licensing arrangement with a global saw manufacturer which Robert has agreed to assist with.

What Our Clients Say
Luke Webb
Owner, Webbs Plumbing and Electrical
The Guarda Edge Saw was the answer I required in order to cut cleanly through 130mm brickwork and plaster in a fully operating aged care facility to extend the dining area. The requirements were no dust, slurry, water and fumes. My regular contractors using conventional equipment said “we can’t help”. Envirochasing Services, using the Guarda Edge Powercutter, could and did.
Jayson Collings
Site Supervisor, Devlyn Constructions
I engaged contractors recently who used the Guarda Edge Power Cutter to cut some openings through a brick wall. Never have we experienced such an efficient cutting machine. It was safe, it was clean, it was fast. It saved us so much time and our customer was so pleased. In our view, this is certainly, industry best practice.

Owner, Kings Road Construction
We are a building renovation carpentry team doing a lot of work in the home renovation space. We are early adopters of Guarda dust, fume, and slurry control technology. When it comes to masonry cutting, we think Guarda is the only safe option for crystalline silica control. Because Guarda has developed best practice, our health and safety regulatory obligations are covered, and our people are kept safe. Guarda equipment also saves us a lot of time due to reduced site preparation and clean-up.
