The choice of material depends on the safety requirements and budget. EPDM (Ethylene Propylene Diene Monomer) granules are the gold standard for colorful, patterned surfaces due to their UV resistance and elasticity. SBR (Styrene-Butadiene Rubber) is often used as a cost-effective base layer to provide impact absorption. For temporary or DIY installations, interlocking PP (Polypropylene) tiles are preferred for their excellent drainage and ease of assembly, while Artificial Turf is ideal for a natural look with low maintenance.
