摘要

A backing mat for a water-permeable artificial grass having a grid-like structure consisting of elastically pliable foamed plastic sections and openings arranged therebetween. To improve the qualities of the artificial grass with regard to tread elasticity bulbous projections are formed of foamed plastic on the underside of the backing mat at the edges of the openings.
