Abstract
A synthetic grass surface comprising widely spaced rows of ribbons and the ribbons having a length about twice as long as the spacing between the rows of ribbons. A particulate material is laid on a matrix of the synthetic grass, and the thickness of the particulate material is as least two-thirds the length of the ribbons. The strips of ribbons are attached by strips of bonding material applied to the back of the matrix or mat. The strips of bonding material are spaced apart and leave areas of mat which are uncoated, thereby providing improved drainage.
