    • The invention relates to a method for producing a polyurethane flooring (129) for a sports field (136), the method comprising:
      - providing (502) reactive components for producing polyurethane, the reactive components comprising an A component (902) being a polyol mixture and a B component (904) being an isocyanate mixture and water (914), the B component comprising:
      ∘ 2,2' Methylendiphenyldiisocyanate (922);
      ∘ diphenylmethane-2,4'-diisocyanate (924);
      ∘ diphenylmethane-4,4'-diisocyanate (926); and
      ∘ isocyanate prepolymer (932);
      - mixing (504) the reactive components for generating a liquid polyurethane reaction mixture (129);
      - applying (506) the polyurethane reaction mixture (128) to a ground (103) of the sports field before chemical reactions in the reaction mixture have generated a solid polyurethane foam, the polyurethane foam after its solidification to be used as the polyurethane flooring.

    • A safety surface (100,500,800) with an engineered shock-absorbing base. The base may include one or more engineered resilient mats. The mats may be fabricated of repurposed tire rubber. The mats may be adjoined edgewise. Adjoined mats may be coupled together. The base may overlay a surface. The base may include upward-facing pockets. Interiors surfaces (103,203,303,403,903) of the pockets (102,202,302,402,502,902,1202,1402,1502a,1502b) may receive loose fill (117,517). An upper layer (118,518,818) may cover the base. The upper layer may bond to the base. The upper layer may seal the loose fill within the safety surface. The upper layer may include poured-in-place surfacing. The upper layer may be textured. The upper layer may include synthetic turf. Impact upon the upper layer may be attenuated by flexion of the base. Mats may be coupled without hardware fasteners. Exterior surfaces (101,401,501,1001,1201,1501a,1501b) of pockets of one mat may be nested into complementarily contoured features of an adjoining mat.
    • 安全表面(100,500,800)带有工程减震基座。 基座可以包括一个或多个设计的弹性垫。 垫子可以由改用轮胎橡胶制成。 垫子可以沿边连接。 相邻的垫子可以连接在一起。 底座可以覆盖表面。 底座可以包括面朝上的口袋。 袋(102​​,202,302,402,502,902,1202,1402,1502a,1502b)的内部表面(103,203,303,403,903)可以接收松散填充(117,517)。 上层(118,518,818)可以覆盖基部。 上层可以结合到基部。 上层可密封安全表面内的松散填充物。 上层可以包括就地浇注表面。 上层可以被纹理化。 上层可以包括合成草皮。 对上层的影响可以通过基底的弯曲来减弱。 垫子可能没有硬件紧固件连接。 一个垫子的袋的外表面(101,401,501,1001,1201,1501a,1501b)可以嵌套到相邻垫子的互补轮廓特征中。
