Full definition
Rubber or plastic flooring with built-in holes, slots, or open-grid structure that allows water, spills, and other liquids to pass through the floor surface to drainage underneath, keeping the walking surface drier and safer. Types: (1) Perforated rubber mats — solid rubber with regularly spaced holes (typically 10-20 mm diameter), providing both drainage and cushioning. (2) Open-grid/grating — interlocking PVC, rubber, or polypropylene modules with large open cells (~70-80% open area) for maximum drainage. (3) Ribbed/channeled — directional grooves guiding water to drains. Drainage flooring is essential in areas with constant water presence where standing water creates slip hazards. Material: rubber (SBR, NR — for industrial, chemical-resistant options: NBR, neoprene), PVC (economical, lightweight), and polypropylene (chemical-resistant, lightweight). Typical dimensions: modular tiles 300×300 to 600×600 mm, thickness 10-25 mm. Anti-fatigue versions available with cushioned base layer beneath the drainage surface. Applications: commercial kitchens, food processing plants, shower and locker rooms, swimming pool surrounds, industrial wash stations, bar areas, and outdoor terraces. Per OSHA 1910.22 for walking surfaces. Brands: NoTrax, Wearwell, Cactus Mat.
