A: Hello Brian Johnson: DMX 1-Step 2.0 can be installed over the floor drain, and moisture or small water leaks will travel underneath the underlayment towards the drain. If desired, DMX 1-Step 2.0 and finished flooring can be installed around the floor drain, for easy access to the drain from above. Customer Care DMX
A: I’d honestly contact the company on their recommendation to tile. You really shouldn’t use plywood as a tile Underlayment in a normal install anyway. Concrete board/ hardie backer is a much better material. Regardless the underlayment is going to give you some flex without the underlayment material being securely attached. This would result in grout cracks for sure. I put a click lock laminate on top of mine and it seems great so far. It’s been down for a few months. I believe you want an uncoupling membrane such as schluter ditra to install tile on top of concrete. Also sold at Home Depot. It gets thin setted down then tile thin setted on that. Good luck on your project.
A: Hello Alessio: Yes, when installing plywood on top of DMX 1-Step Underlayment or DMX 1-Step 2.0 Underlayment, ceramic tiles could be installed on top. However, it is recommend to use a decoupling membrane when installing tiles instead. Customer Care DMX
A: Yes, But...you need to fasten the subfloor to thru the DMX-1 to the floor beneath. I installed over concrete. I had to use 32 tap-con screws per 4 x 8 sheet with an ASTM sealant in each screw hole to prevent moisture from coming up thru the holes or down into the holes in the concrete. It was solid as a rock when complete.
A: Yes. Assuming you have a concrete floor that is reasonably flat and smooth. It is a very tough product but you can cut it to fit with a good pair of scissors.
A: Probably not in the way that you are thinking. Please re-think this. Gym machines can be heavy - very heavy. The feet of the machine will produce a lot of pounds per square inch. This underlayment is not engineered to withstand that high of a psi load and maintain the free air space that it is designed for. It would crush under that kind of weight and not maintain any airspace, which is how it prevents mold & mildew. Re-think this. You want gym machines to be mounted on solid ground, or at least feel like it. You don't want to be on a wobbly machine. Nor do you want to stand on a wobbly surface when you are working out. You can do this a different way. Mount the machines and weights directly on the concrete floor. Get the specialized mats for weights - it's the safe way to do that. If you have the ceiling clearance, you could make the same airspace using rigid spacing materials with a path for airspace, covered by rigid plywood. But, hey - build the airspace behind the basement walls, epoxy coat the floor and walls & buy a dehumidifier.
A: Well, all I can say is that I put vinyl flooring over this product and now have a full sized refrigerator sitting on it, so I would think gym mats and equipment would be okay as longs as it's not lifting weights which can be dropped on the floor.
A: The specifications state this product can withstand 89 lbs/sq. in. Take the weight of a piece of equipment, determine the amount of area it occupies (its footprint) in square inches and divide the equipment's weight by its footprint. Be sure to include your weight. If the number you calculate is less than 89 you are good, if it is not you may have to increase the footprint by getting a thicker underlayment.
A: The DMX is actually pretty stiff and the dimples are difficult to compress so a distributed load with a plywood layer 3/8” or better should not be any problem.
A: Hello GymBuilder: DMX 1-Step has a compressive strength of 4,000 lbs per square foot. Installing plywood on top of our underlayment would dissipate the weight further. It all depends on the compressive strength of the plywood to know how much more weight it could hold. A home gym can be rest on top of our underlayment, as long as it does not exceed the weight limitations. Customer Care DMX
A: I think not, it is not made for this application, just remove the carpet first.
A: No, this cannot be used over carpet. No hard flooring can be installed over carpet.
A: No. It should be laid over a smooth hard surface. It is intended to lay directly over concrete as a moisture barrier. A carpet would trap moisture and nullify the intent of the dimples, which is to leave a gap to allow moisture to dissipate during dryer conditions. The air gap also provides some thermal insulating effect, the floor doesn't feel cold like concrete floor.
