Polished concrete is a durable, low-maintenance floor with a clean, modern look. For retail stores, offices, restaurants and showrooms along St. Albert Trail, it means a floor that handles daily foot traffic and needs little more than dust mopping.
In industrial spaces such as Campbell Business Park, it stands up to heavy machinery and forklift traffic. Grinding and polishing also eliminates concrete dusting and improves light reflectivity.
Older slabs are not a problem. Concrete that is 5, 20 or 50 years old can usually be polished, and older concrete often shows unique aggregate patterns.

20+ years of concrete coating experience
A hard-wearing, dust-free floor for shops and warehouses.
Our crews follow a multi-step process. Larger commercial and industrial floors usually take 1 to 2 weeks.
The surface is cleaned and inspected, and cracks or spalling are repaired. Control joints can be filled first.
Diamond grinding takes off old coatings and residue and opens the concrete to the aggregate level you want.
Each pass uses a finer diamond grit until the floor reaches its final clarity and sheen.
A chemical densifier hardens the concrete and improves its resistance to wear and stains.
A penetrating sealer finishes the floor, so routine cleaning stays easy.

It is one of the most cost-effective long-term flooring options for commercial and industrial spaces.
With proper care, polished floors last 20+ years, and many last 30+.
Dust mop, damp mop with a pH-neutral cleaner and reseal every 2 to 3 years.
Textured finishes or slip-resistant treatments for kitchens, plants and public areas.
