USEFUL LINKS:
Easy Ordering
We offer free estimating through our Online Estimate Form. Our preliminary estimate are designed to give you a quicker budget estimate based on the information provided and picture you send us. This allows you to review and compare information, so that you can select us as your trusted concrete flooring installer.
Once the preliminary budget is approved, we will schedule a personal appointment with you, to discuss options and project's details, then provide a detailed written estimate with firm price.
Over the decades we determined that this way of estimating new projects produces the best results both for our clients and our schedule, hence being able to dedicate more time and attention to the clients committing to work with us.
Installation Process
Refinishing a concrete slab by diamond abrasion is a very skilled trade that requires years of experience and technical expertise. The process is customized to every project but typically includes slab grinding for preparation, necessary repairs, appropriate detailing, honing/polishing, densification, sealing and burnishing.
Every slab is different, as much as every client is different, so we strive to listen and understand your needs with diligence, determine options and a plan of action, and create the proper expectations, so you know before starting what can be achieved. Our projects are all about details, planning, sampling, and creating the right expectations. That's where we excel!
Benefits of Polished Concrete
Diamond polished concrete and diamond polished cement overlays are among the most durable and beautiful floors on the market.
DelGrosso Design produces surfaces that are:
-
extremely resilient
-
virtually scratch-dust-mold resistant
-
very easy to maintain, clean, and sanitize
-
providing excellent slip resistance, even in wet conditions
You might see polished concrete in a shopping center floor, or a church, hospital, hardware store, school, and many other public spaces, and think, "How nice it would be to have something similar in my house". Now you can!
We personalize polished concrete, making it extremely attractive, trendy, stylish, with colors and shapes that make your neighbors and friends say "wow"!

Pool Decks Restoration
Over the decades, DelGrosso Design perfected a superior restoration system for concrete pool decks. So often, those concrete areas around pools are worn out and beaten up, as they corrode faster than any other concrete areas around your house.
Don't worry, that's pretty typical, as it is so hard to properly maintain concrete around pools.
The system that we developed will restore your surfaces, making them very durable, beautiful, and slip-resistant, easy to clean and maintain, and soft on your feet!
In this way, you will be able to enjoy your backyard area without stress, and entertain family and friends with no worries on your mind.
Check out the Testimonials page, where our clients often spontaneously express their gratitude for our hard work when we exceeded their expectations.
Concrete Slab vs Cement Overlay
Cement is one of the components in concrete. It is a fine powder that binds the other ingredients through a process called "hydration". In addition to cement, concrete contains stone aggregate, which, once exposed during the initial grinding phase, creates the classic "salt and pepper" look of polished concrete.
If a slab is not in conditions suitable for direct refinishing, a cement overlay (we also call it "topping") can be applied to create a brand new surface.
The polishing process and floor performance are virtually identical on both cement and concrete, although the processes are different in specifications and installation sequence. Several types of diamond polished cement overlays are available, so we can create unique tones and designs.
