Most likely you are saying this just by the grout's looks. The ground moisture of the grout-if it is not extremely high-can not be noticed by human eye.

We use special kinds of machinery and tools to measure it, and report it to the investor periodically.

A flooring material, no matter how high quality it is, would not last long, and/or would not give its best performance if it not installed properly. The meaning of a ground with moisture is that, there is vertical movement of water steam from the lower levels of the ground, to the grout surface. This is a physical movement, and no material or adhesive in the world can resist it.

This is why, we require the ground moisture level to be under 4% for syntethic systems, and under 2,5% for hardwood systems to install. An installation that will be made above these levels will contaion very high risk for the life span of the flooring system. Some possible defects are partial rising, turning, or getting hilly.(for the hardwood systems)

If you are our customer, you should be given a ''Cleaning Instruction Sheet'' If you did not receive it by mistake, please contact us to obtain one, and do not use any other chemicals to clean your sports hall. Please keep in mind that your pvc sports flooring system could be harmed seriously by using the wrong chemical.

If your product is glued to the subbase with an adhesive, yes, you can use a machine with soft round brush. But, if you have a floating rubber-epdm flooring system, we do not recommend the usage of a machine with a round brush since it can cause the rolls to move.
