The weight of non-infill artificial grass is not a fixed figure—it varies based on several technical factors including material composition, yarn structure, tuft density, backing layers, and overall thickness. At VivaTurf, we engineer our non-infill grass systems with precision, balancing weight with durability, comfort, and performance for different use cases such as football pitches, croquet fields, school playgrounds, or rooftop gardens.
Material Composition: The PE/PP Blend
VivaTurf non-infill grass uses 100% virgin polyethylene (PE) and polypropylene (PP) in varying ratios to produce turf yarns. These materials have different physical characteristics that directly affect weight. PE is slightly heavier but offers superior flexibility, UV resistance, and cold-weather tolerance. PP, being lighter in density yet stiffer in structure, contributes to reducing the overall system weight. For example, turf yarns with a higher PP ratio are lighter but stiffer underfoot, while those with more PE offer balanced weight and better resilience. By tailoring these blends, we ensure optimized turf performance without unnecessary weight burden.
Yarn Shape and Structure: Curly + Straight Combo
Unlike traditional monofilament turf, VivaTurf adopts a mixed curly and straight fiber structure. This design not only enhances ball control and reduces skin friction but also affects weight. The curled fibers increase air gaps within the turf, lowering material volume per square meter without compromising surface density. In contrast, fully straight and tightly packed yarns add weight but reduce air permeability. Our straight-curly configuration achieves an ideal balance between lightweight design and functional performance, especially for sports like football where impact absorption and ball bounce are key.
Tufting Density: The Backbone of Structural Support
Yarn density plays a pivotal role in determining turf weight. VivaTurf’s football-grade non-infill grass features densities up to 20,000 tufts per square meter, creating a “three-dimensional support network” that maintains performance under pressure. Naturally, the more yarns per unit area, the heavier the grass becomes. High-density configurations are used for heavy-duty sports venues, ensuring durability over time. For lighter-duty applications—like backyard landscaping or decorative rooftops—we reduce tufting density, resulting in a lighter and easier-to-install system.
Backing System: Functional and Weight-Efficient
Backing materials are another decisive factor in total turf weight. At VivaTurf, we use breathable yet waterproof composite membranes, often layered with cold-resistant PU adhesives and glass fiber reinforcement mesh. These backing combinations are engineered to reduce weight while maintaining tensile strength, dimensional stability, and drainage performance. In contrast, traditional heavy rubber backings significantly increase turf weight and complicate transportation and installation. By avoiding such materials, our non-infill grass maintains a favorable weight-to-performance ratio.
Pile Height: Thickness Matters
The turf’s thickness—often referred to as pile height—also correlates with weight. For professional football applications, our non-infill systems are typically 30mm thick, designed for optimal shock absorption and gameplay quality. Gateball turf ranges from 20mm to 30mm, designed with ball roll precision in mind. In recreational spaces, like kindergartens or rooftop gardens, we tailor the turf from 20mm to 50mm depending on safety and comfort needs. Thicker turf with longer yarns is naturally heavier, but VivaTurf adjusts backing and fiber density to ensure practical weight for each setting.
Smart Weight Engineering for Every Scenario
There is no one-size-fits-all weight for non-infill artificial grass—it’s a result of careful engineering across multiple parameters. At VivaTurf, we combine advanced material science with tailored structural design to deliver turf that is not only functionally superior but also optimized for weight. Whether it’s a high-performance football field or a cozy rooftop retreat, our non-infill grass systems are built to perform without unnecessary load.
