Polished Concrete Floors
We install beautiful, durable polished concrete floors in warehouses, factories, offices, and other institutions.
VOC free and environmentally friendly.
What Makes Our Polished Concrete Floors Special
Our knowledge of concrete science, diamond tool technology, machine requirements and chemical treatments helps us produce better floors.
We understand the basic chemistry and fundamentals of concrete. This allows us to properly assess your concrete floor and make the right recommendations.
We utilize the most advanced diamond tools because they deliver fast grinding and better surface finishes. This means lower costs and better quality polished concrete floors.
Our concrete polishing system is capable of mechanically polishing the concrete surface to a 3000 grit finish. We are one of a small number of companies capable of providing 3000 grit polished concrete.
Most polishing systems can’t mechanically polish the surface above 800 grit even though the systems go up to 1500 and even 3000 grit. Many of these polishing systems use resin transfer to create the polished look.
We only use polishing systems that mechanically polish the concrete surface. This results in better quality, longer lasting floors.
The machines we use are modern, industrial, planetary floor grinders paired with the heavy duty vacuums. This means an almost dust free job site and reliable timelines.
We use best in class chemicals to maximize the performance of our polished concrete floors. High quality densifiers, joint fillers and repair materials are important parts of the process.
We Offer Three Levels of Polished Concrete
Level One is an 800 grit polish, it’s created using a grinding process that consists of 7 grinds. This is a basic polished concrete floor with low shine, gloss and clarity.
Level Two is a 1500 grit polish, it’s created with the same grinding process as the 800 grit polish plus the addition of the 1500 grit. This process consists of 8 grinds and results in good shine, clarity and gloss.
Level Three is a 3000 grit polish which is the full concrete polishing system. This process consists of 9 grinds and produces the highest level of shine, clarity and gloss.
Here are the specifications for our three levels of polished concrete:
How Long Do Polished Concrete Floors Last?
A polished concrete floor should last between 2-7 years depending on these primary four factors:
- hardness of concrete (MPa)
- type of traffic
- traffic volume
- exposure to substances.
High strength concrete (35, 40, 45MPa) will have the longest lasting polished concrete. It’s more difficult and expensive to polish these floors but it is worth the effort due to their extreme durability. These floors are suitable for high volume and intensity environments.
Low to moderate strength concrete (25-30MPa) is suitable for low volume and intensity traffic.
The type of traffic will affect the life of the floor. Light pedestrian traffic has little wear on a floor while high pedestrian volume can cause high wear.
Forklifts and vehicles are moderate to heavy traffic depending on the type. They will demand more from the floor.
Volume is often overlooked when specifying flooring. A low traffic area poses few problems but a shopping mall or high volume industrial space requires a highly durable floor. Traffic volume is a critical consideration.
Exposure to substances is the wildcard. Certain chemicals or substances can damage polished concrete on contact and need to be limited. Exposed concrete floors are particularly susceptible to acidic liquids.
Other substances like deicing salts can also damage the surface. Salt-proof densifiers can minimize salt damage if applied during the installation. Oils and solvents should be generally keep away from the surface.
800 Grit Polish – 7 Grind
1500 Grit Polish – 8 Grind
How to Choose the Right Polished Concrete Flooring System
The key to choosing the right polished concrete floor is understanding the difference between the 3 levels.
All the levels will perform similar in terms of life and durability, the primary difference is the aesthetic appearance.
If the floor is being used for utility purposes, the 800 grit basic polished concrete is sufficient. The 800 grit’s low sheen, clean appearance is great for commercial and industrial spaces that value utility over aesthetics.
The 1500 grit provides an improvement in gloss, clarity and shine over the basic 800 grit polish without a high gloss finish. It is excellent for environments where a clean, refined appearance is required.
A 3000 grit polish provides the highest level of shine, clarity and gloss with substantial light reflectivity that improves ambient light by up to 30%. It elevates concrete flooring to sophisticated level.
The terrazzo look can be used with all levels of polished concrete, it is a great alternative when you want a more organic appearance.
Terrazzo Look Polished Concrete
Terrazzo look also known as aggregate exposed polished concrete is an additional feature that may be added to any level of polished concrete. This process uses very aggressive grinding tools to remove approximate 3/16-1/4” of surface concrete to expose the stone below the surface. The floor is typically ground 6-8 times in perpendicular directions. Then a standard polishing process is used to polish the concrete floor.
A homogenous exposure of aggregate is not guaranteed with this type of polished concrete but you can expect about 90% consistency.
When a concrete slab is poured, multiple factors like mix design, finishing techniques etc. may affect where the large aggregate settles. Some aggregate may settle well below the 1/4” depth level which will result in patches with no exposed aggregate. A customer must be comfortable with this possibility before going ahead with a terrazzo look polished concrete floor.
Any existing concrete floor can have the terrazzo look, providing it meets the requirements outlined in the “Can Any Concrete Floor be Polished section”.
Stained Concrete Floor
Polished concrete floors may be stained a wide range of colours and patterns to achieve a specific look. Concrete is a porous material and liquid stains can be applied to alter the colour of the surface.
To achieve a vibrant coloured floor, a stained concrete floor will need to be coated with a clear polyaspartic coating. To create a concrete floor with muted colours, it can simply be polished once the concrete surface has been stained. Whether the floor is coated or polished, stains add another design option to polished concrete flooring.
