Product Questions:

Q: can this product be used outdoors
A: This product is designed for indoor use only.
Q: Can this be used as the floor itself, rather than an underlayment, for a small home gym (over cement)?
A: We suggest going with a thicker material for home gym use. Here is a comparable product at 3/8 inch:
Q: Could this product be used over concrete and under marley? We are thinking about putting this in our basement and wondering if it would work as an underlayment for pointe, ballet, modern, and jazz.
A: Consider this underlayment instead: We would also suggest an interlocking court tile over the plyometric rubber for pointe:
Q: Would you recommend using this underlayment beneath 1” thick foam mats on concrete for a martial arts gym?
A: We recommend installing the foam mats directly over the concrete.
Q: Can this be installed under carpet tiles?
A: That would depend on the type of carpet tiles. Please contact us directly for assistance or recommendations.

Customer Rating:

The rubber 3mm underlayment went down quickly and smoothly. We were able to get all of the underlayment and the gym floor tiles installed in one day. The product is great and it absorbs any sound or movement associated with a floating gymnasium floor. I would highly recommend this product due to it's quality and ease of use/installation. Our product order number was 1463016. Greatmats was also outstanding to work with. They got the product to us in California quicker and cheaper than any of our other options. Thank You!

Customer Rating:

This is a great underlayment option for the Greatmats Max tiles which installed very well.

Customer Rating:

Our initial contact was with Ryan Noll, who was very eager and willing to help. His professionalism and good customer service was very welcoming and appreciated by our company.

Customer Rating:

Great rubber padding for a workout floor. Easy to install, durable, and surprisingly effective for the thickness.

Customer Rating:

I used the 3mm rolled rubber mat as recommended on a dry, clean concrete slab in my basement. I cut it with a utility knife, a large framing square to cut it straight and used "nothing" else on the slab like glue, etc. The rubber mat stayed in place while walking on it to install Tile Max flooring. I liked the product & I'll use it again to finish a couple more floors in my basement.

Customer Rating:

Product is great. Installed under the tiles I purchased from Great Mats.

Customer Rating:

Very good quality and easy to work with. We almost were going to put down flooring without it. The extra money for this pad was worth it.
