Abstract
The surface covering material, which is particularly suitable for external uses such as ground or floor covering in golf driving areas, comprises a multi layer structure, which itself comprises (a) an outer layer 1 comprising a preformed fabric 2; (b) an underlayer 4 comprising a rigid liquid impermeable sheet material bonded to the undersurface of the outer layer by means of an adhesive bonding layer 5; and (c) a layer 7 of relatively more flexible, hydrophobic closed cell foam, the surface of which is secured directly to the undersurface of the underlayer either by means of a hot melt adhesive or by sintering.
Claims19
A surface covering unit, which comprises a multi-layer structure comprising:
- (a) an outer layer comprising a preformed fabric;
- (b) a substantially rigid liquid-impermeable sheet material bonded to the undersurface of the outer layer by means of an adhesive bonding layer;
- and
- (c) a layer of relatively more flexible, hydrophobic closed cell foam, the surface of which is secured directly to the undersurface of said sheet material.
