Full definition
Heavy-duty rubber flooring designed specifically for fitness centers, weight rooms, CrossFit boxes, and sport training facilities where the floor must absorb high-energy impacts from dropped weights, support heavy equipment, and withstand intense foot traffic. Material: recycled tire rubber bonded with PU resin (most common — economical, excellent performance, sustainable) or virgin NR/SBR (premium, more consistent properties). Thickness: 8-15 mm (cardio areas, machine rooms), 15-25 mm (free weight areas, functional training), 30-50 mm (Olympic lifting platforms, heavy deadlift zones). Density: minimum 900 kg/m³ (higher density = better impact absorption and equipment stability). Impact attenuation: reduces peak force by 30-60% compared to concrete, protecting subfloor and reducing noise (critical for upper-floor installations). Formats: interlocking tiles (most popular — no adhesive, easy replacement), rolled sheet (fewer seams, best for large areas), and custom platform systems. Color: black base with EPDM color flecks (10-30%) — blue, green, red, gray available. Noise reduction: 15-25 dB impact sound improvement (IIC). Per ASTM F2772 (sports flooring) and ASTM F1292 (impact attenuation). Must resist: sweat, cleaning chemicals, rubber mat/shoe marks, and dropped dumbbells. Brands: Ecore, Regupol, Dinoflex, IncStores, Rubber-Cal.
