Walk-off mat system - Stone panels with a recess below.

The project team of an office building is interested in using a new product called C/S Floorometry® 401 for the walk off mat: http: //www.c-sgroup.com/files/literature/Floorometry_0.pdf This is a flooring system composed of stone panels with a built-in drainage device that allows dirt and water to fall through to a recess below. It incorporates an anti-slip surface coating and its roughness can be improved with additional serrations. The modules can be removed to clean the recess below. In the product catalogue it is written “LEED® IEQ Credit 5 Contribution (Pollutant Source Control) – Yes” but this kind of system is not mentioned in the reference guide. For this reason, the project team would like to know if this system meets the IEQc5 credit requirements as described in the product information. Thanks in advance.
