Hidden Asbestos Hazards are very common in Calgary homes built before the late 1980s. We understand that your old basement floor might look like simple plastic or linoleum. Our team observes that many nine-inch tiles contain high levels of mineral fibres. Because these fibres are locked in the glue and tile, they stay safe until disturbed. We want to warn you about the risks of sanding or prying up old floors. Consequently, your DIY renovation could release dangerous dust into your breathing air. Furthermore, the black adhesive used under these tiles often contains the same hazardous minerals. We believe that testing your floor before you start work is a smart choice. This prevents accidental contamination of your entire living space.
Recognizing Older Tile Sizes and Styles
You can often identify potential risks by looking at the size of the tiles. We find that older, dangerous tiles usually measure exactly nine inches by nine inches. While some twelve-inch tiles also contain minerals, the smaller ones are much more common. Furthermore, these tiles often have a very hard, brittle texture when you touch them. They do not bend easily like modern vinyl products found in stores today. Consequently, they shatter into sharp pieces when you try to remove them with a shovel. You should also look for a “mottled” or oily pattern on the surface. These designs were very popular during the decades when mineral additives were legal.
The Danger of Black Mastic Adhesive
The glue holding your tiles down is often more dangerous than the tile itself. We observe that this “black mastic” was made with thick mineral fibres for extra strength. Consequently, it creates a very sticky and difficult mess during a home renovation. You must never use a grinder or a sander on this dark glue. This action turns the mineral fibres into a fine powder that floats for days. Furthermore, the dust can settle into your carpets and furniture throughout the house. Our team suggests using wet methods or specialized chemicals to soften the adhesive safely. Keeping the material wet is the best way to prevent the dust from rising.
Why Scraping and Sanding is Risky
Sanding a floor is the fastest way to put your family at risk during a project. We find that the heat from a sander releases fibres into the air instantly. Because these particles are microscopic, you cannot see the danger you are creating. Furthermore, standard shop vacuums cannot catch these tiny mineral threads in their filters. The vacuum will simply spray the hazard back out into your room. Consequently, you will breathe in these particles while you work and while you sleep. Our team always uses high-efficiency air filters to keep the work area clean. We prioritize your safety by containing all dust behind plastic barriers.
Professional Testing and Safe Removal Options
Getting a lab test is the only way to know the truth about your floor. We are the Best Abatement & Remediation Company in Calgary for helping you identify these hidden floor risks. If your test is positive, we can remove the tiles using safe, professional techniques. This includes using negative air pressure to keep the dust inside the work zone. Furthermore, we dispose of all debris in sealed bags according to local safety laws. This ensures that your home stays clean and your renovation can proceed safely. Taking this step protects your health and your home’s future resale value. Please Contact Us to schedule a floor inspection before you renovate.
FAQ
How can I tell if my floor has asbestos?
You cannot tell just by looking at the tiles with your eyes. You must send a small piece to a laboratory for a professional analysis.
Is the floor dangerous if I don’t touch it?
No, the minerals are locked inside the material and are not a risk. They only become dangerous when you break, sand, or scrape the tiles.
Can I put new flooring over the old tiles?
Yes, covering the old floor with new vinyl or carpet is often safe. This is called encapsulation and it keeps the old fibres trapped underneath.
Why were these minerals used in floors?
Manufacturers added them to make the tiles fireproof and very durable. These floors were designed to last for many decades without wearing out.
What should I do if a tile breaks?
You should wet the area immediately to keep the dust down. Then, cover the spot with tape or plastic and call for professional advice.
