Super product. Very convenient. Easy to install by DYI. Affordable. It perfectly fits my renovated outdoor patio of EPDM cover. I am very happy with the product & the customer support service.

Our existing deck had serious problems.
To enter the study space on the second floor, the Clinic staff people had to climb up the outside concrete stairs from the Clinic, and then walk across a modified bitumen roof to the door.
We paid dearly to have a wooden “platform” type “deck” built on the modified bit roof. It was terrible. The platform was taller than the top stair, and also taller than the threshold of the entrance door to the study. We were still stepping onto the bare roof at the top of the stairs, and then stepping down onto the bare roof close to the entrance door to the study. Everyone on the Clinic staff wanted to simply walk across a flat smooth surface to their door.

“StayLock” perforated roof tiles have greatly improved happiness and safety of the Clinic study. The physicians and the nurses no longer trip over the edge of the wood deck. They don’t need to step over the snow-and-ice puddle in front of their door.

We have covered the ugly black roof without repeating the failure of the previous design:
The StayLock deck covering is thin enough to be built all the way to the door, and all the way to the top of the stairs. It is no thicker than a thickly padded rug.
The tiles are easily removable, in case roof repairs are needed.
The StayLock tiles are flexible enough to “relax” down onto the underlying modified bitumen roof, which is definitely not smooth and flat.
We are shovel snow and apply salt.

Our new StayLock tiles are thin, removable, flexible, durable, and beautiful. Our deck is now a place to have lunch with a friend.

I used Greatmats on an outside GaGa Put and they worked very well. Great product.

Perfect solution to incorporate a mulch-free zone for our toddlers on the playground. Tiles are flexible and stay put when locked together. Installation was quick and easy. We added the border edge for a finished look and smooth the transition.

Sales team was fantastic. Product arrived quickly. Both spaces were completed in a few hours. This was exactly what we needed.

I'm looking forward to making my mat larger and adding the border to it. Now, if my dogs have an accident on it, I can hose it down and I don't have to change out the mat every few months (saving me money). Just an FYI, the mat is strong, sturdy, and easy to put together. It looks nice and clean. I wish I had ordered the borders the first time around, but I didn't. They will make the mat look finished.

Great outdoor tiles. Ordered 144 tiles for my 12x12 covered patio. Used only 121 since the internal dimensions were 11x11, definitely should have taken that into account before ordering. Installation was quick, ~30 min. A rubber mallet sped things along but was loud. They can be installed with just pressure from your fingers if you want a more quiet installation. There was a mild plastic smell but that went away after a week. It's comfortable on bare feet and perfect for the family!

We have loved the flooring system since it was installed a month ago! It was so easy to put together and serves as a great base for my niece’s play set. It is also easy to clean. We will be purchasing additional flooring to create more of a walkway around the play set.

Product arrived quickly. Packaging was appropriate. Product was easy to install and looks great

Love the mats. These were perfect as a flooring for a kids playhouse we set up over concrete tiles. The mats make a safe, comfortable floor covering that is easy to clean. The installation was simple and quick to do for the 6'x6' area.

Perfect for our large and very windy rubber membrane roof top. It was pretty easy to DIY (we used a rubber mallet to avoid damaging our roof or our fingers) and looks fantastic for the price.

These seem good. I'll know more as time goes by.

First, they are more ''rubbery'' than I had envisioned. That's probably good for absorbing impacts, but I'm not sure how well they'll distribute weight placed upon them. If you put furniture on these, make sure they have broad footprint to the legs/feet don't press through a weak point in the tiles. (The little 1'' X squares in the tiles feel a little weak.) And don't walk on them wearing heels. ;-) They are also a lot harder to interlock than the video makes it seem. You have to work them into the slots, which takes times and effort. I ended up using a screwdriver handle as a way to apply hard pressure exactly where I needed it. I did a lot of research, and these seem to be a good choice. I'm glad I got them.

My wife and I were a little skeptical of the price point, but when these mats arrived we were surprised by the quality, weight, and thickness. The mats arrived in good condition, even though we’ve had issues in the past with other companies sending us boxes this big and heavy. Assembly was a little tedious, but we hit our stride once we started using a mallet to get the mats to snap together. We’d recommend watching a YouTube video about how to install before just trying to do it yourself. Overall, a positive experience. We’re glad to have this in place to protect our newly remodeled balcony and the rubber membrane that protects it. These mats are a relatively small investment to make sure we get years of use from our balcony.

Although the product is great and fulfilled the need I had - I was disappointed in GreatMat's customer service and shipping policy. I purchased the original order in October of last year. As it arrived just prior to winter setting in here in the northeast - I stored the boxed GreatMat items until spring when I proceeded to install the flooring over the 2nd floor balcony rubber roof. When I got to the end of the installation I realized I had been shorted 2 tiles. I had accurately measured and ordered and was shorted in the shipment. I emailed your customer service May 3rd with pictures explaining and had to reorder and repay for the missing 2 tiles again with expensive shipping charges. I did not appreciate this lack of accomodation of the customer.

Seems to work quite well. We installed on top of wood chips, which made it very soft without getting wood chips stuck in your bare feet. Only drawback is that it does get quite hot in direct sunlight. At least the solid black mats do.

Easy to install...put down mats very quickly and easily. Looks very nice on outdoor deck.

My concession trailer with your mats that you helped us pick out! Thanks so much!!!

Love the product and so do the grandkids and dogs!

Thanks for a great product.

Love it!

Building a playhouse for my granddaughter and needed an outside base to put it on that was soft enough for a toddlers falls but durable enough for Ohio weather. So I contacted Greatmats Chat. They recommend the Staylock tiles. Ordered 36 sq ft in light gray. They arrived three days later. Assembling them was not only easy but fun (think bubble wrap snapping).
They looked so great I thought I needed to expand the base and put in the borders. So back to chat for advice. They frankly told me that the next lot of light gray might be a shade different. Taking that advice I ordereded the black tiles with the borders. Just got them today and have half set up. Beautiful! Great company to deal with.

Perfect solution for a small balcony over roofing. Formerly had a heavy wooden pallet which was difficult to move. This looks good, was simple to install and can easily be removed for cleaning when it becomes necessary.

The installed tile is AWESOME! The students are going bonkers in the Gaga ball pits today!

This product installed easily on landscape fabric for a swing set / slide in my backyard for my sons to play on. The tiles were easy to snap together using a board and a rubber mallet. Some of the tiles snapped with hand pressure, but some of the interlocking pieces were a little bit cold and the rubber mallet got them to go through the rectangular slots. The pieces were a little cold when they came right out of the box, but everything warmed up and became more pliable pretty quickly in the sunlight of a 60 degree day.The tiles are pretty soft to fall on

Great product. works well on our rubber roof with our raised garden. will be purchasing more for the next garden soon.

I am very satisfied with the Greatmats product. As advertised, the product was shipped timely and lived up to the specifications described. I purchased approximately 100 of the square foot tiles plus the corresponding corner and border tiles. The flooring was installed on my second floor outdoor porch above a roofing membrane flooring. The interlocking edges and the relatively flat surface that I was installing the product made it easy to install. Prior to purchasing the product I had some reservations as to how difficult it would be to cut some of my edge tiles, however with a pair of large sharp scissors I found the tiles were able to get cut easily. It took me about three hours to complete the entire installation. The product has been in place for about a month and I am very happy with the finished product.

The Great Mat product we purchased is great. The middle school students truly enjoy playing monkey ball with the new and safer surface. It is also more clean. Students are no longer getting dirt on their pants and possible holes due to the dirt in the pit before. We thank you for your product and your great service!

Great product. Just the thing I was looking for to put over a rubber roof deck to protect it.
