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 diamond polishing system is capable of mechanically polishing the concrete surface to a 3000 grit finish. We only use polishing systems that mechanically polish the concrete surface and don’t use resin transfer to create the finish. This results in better quality, longer lasting floors.

The machines we use are modern, 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 Four Levels of Polished Concrete

  1. 400 Grit: Basic polished concrete floor with low shine. Excellent for industrial floors like factories and warehouses. Also, used in retail and offices preferring low shine floors. 
  2. 800 Grit: Mid level polished concrete with good shine, clarity and gloss. Commonly used in manufacturing and logistics when appearance is important or offices and retail when a mid level shine is desirable. 
  3. 1500 Grit: High shine, clarity and gloss. When you want a high-end appearance for commercial, institutional or retail spaces.
  4. 3000 Grit: Best of the best. Highest shine, clarity and gloss. Suitable for high-end and luxury environments.

How to Choose the Right Polished Concrete Floor

The key to choosing the right polished concrete floor is understanding the difference between the 4 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 400 or 800 grit polished concrete levels are sufficient. The low to medium sheen and clean appearance are great for commercial and industrial spaces that value utility without sacrificing aesthetics.

The 1500 grit provides an improvement in gloss, clarity and shine over the 800 grit providing a high gloss finish. It is excellent for environments where an upscale, refined appearance is required. High light reflectivity will also noticeably brighten the space.

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 a sophisticated level for luxury or high-end environments.

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 1/4” of surface concrete to expose the stones 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 typical 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”. 

How Long Do Polished Concrete Floors Last?

A polished concrete floor should last between 3-10 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 environments.

Low to moderate strength concrete (25-30MPa) is suitable for low volume traffic.

Polished concrete warehouse floor

The type of traffic will affect the life of the floor as well. Light pedestrian traffic has little wear on a floor while high pedestrian volume arriving from outside the building 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 kept away from the surface.

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.
