When selecting fake lawn for residential use, one of the key factors is how effectively it reduces impact. Shock absorption refers to the turf’s ability to cushion blows during activities like running and jumping. This is fundamental to user comfort, particularly in reducing risks of concussions, cartilage wear, and overuse injuries. Shock absorption performance differs widely, and understanding these distinctions enables you to make a smarter investment.

The underlayment beneath the turf significantly influences shock absorption. Professional-grade fields often employ a multi-layered design composed of EVA padding or recycled rubber granules. These materials are engineered to compress under load and then rebound to original form, thereby dissipating kinetic energy. Turf installed directly on concrete provides negligible shock absorption and can increase likelihood of trauma.

The length and thickness of synthetic fibers also greatly affect performance. Increased blade length generally offer more cushioning because they provide more room to flex. However, overly tall blades they may become unstable underfoot. Fiber gauge and geometry are equally important—some fibers feature textured surfaces to boost rebound characteristics. Higher fiber concentration typically results in superior shock absorption because more material is available to disperse energy evenly.

Infills serve as a vital component. Common infill options include silica granules, SBR material, and emerging eco-friendly alternatives such as cork. Rubber infills remain the most popular choice due to their consistent resilience. Sand is more affordable but offers limited impact reduction and tends to compact over time. Multi-material blends integrate complementary materials to optimize durability. Field analyses indicate that fill level is a decisive factor, with a 15–20mm range often recommended for peak shock mitigation.

Environmental conditions modulate performance. In high-temperature zones, turf may harden due to thermal expansion, thereby reducing cushioning. Innovative designs now include cooling backings to counteract heat buildup. Moisture levels also change behavior: while certain turf types perform optimally with light dampness, others may lose resilience if over-saturated.

Independent laboratories use established methods such as the fall height measurement to quantify shock absorption. A reduced impact value indicates better impact mitigation, with regulatory limits typically set no higher than 200 for sports surfaces. Consumers should select systems that have been independently tested by accredited organizations such as the ASTM International.

When evaluating turf options, ask for certification reports and select the configuration to your primary function. A home landscape doesn’t require the same safety level as a competitive soccer pitch. Always work with a certified expert who can tailor a solution based on your financial constraints, regional weather, and 熊本 人工芝 施工 usage intensity. Choosing turf with proper shock absorption is not merely about comfort—it’s a vital protective measure that can prevent chronic injury.
