Fiction: All rubber mats are the same.
Fact: There is a difference. Many cheaper mats are 'crumble mats' - large crumbs of rubber that never quite vulcanize. They inconsistent manufacturing process and lower quality materials produce an inferior mat. It is also not very soft.

Fiction: Kraiburg isn't worth the price.
Fact: Compare the track record. Compare the warranties. Kraiburg flooring is softer and lasts longer. That alone is worth the price. Remember, less than 1 in 1,000 Kraiburg mats fail due to material defect.

Fiction: Rolls are better than interlocking mats.
Fact: Rolls with straight edges are harder to control than snug fitting interlocks.
Fact: Expansion and contraction are more of a problem with a large roll rather than an individual mat
If not stretched, rolls will form waves and bubbles. These are far less likely to occur with interlocking mats.
Follow up question: if there is a problem, how much will be replaced?

Fiction: The interlocks will come apart.
Fact: If anchored properly, the interlocks have very few problems. It is important to follow the manufacturers guidelines.

Fiction: Conveyer belting will do the same and cost less.
Fact: Used belting will cost less. However, it provides very little benefit when compared with concrete. Belting was designed to not compress under load - eliminating half of the benefit of installing rubber flooring. It will get more slippery the longer it is installed. If it were softer than concrete, why do they have to groove it?

Fiction: Cheaper mats will do just as well and save money.
Fact: There is a difference. Not only are Kraiburg products designed to be softer, they are designed to last longer. If you buy an inferior product 2 or 3 times in the same time you would have Kraiburg, do you actually save money?
