Sand trap liner assembly characterised by the retainer layer including plurality of spaced apart projections

摘要

A liner assembly (322) for a sand trap (310) with a cavity having a perimeter, a base (318) within the cavity, and an exposed filling material (316) positioned within the cavity is disclosed. The liner assembly (322) for a sand trap (310) includes a retainer layer (329) that is positioned between a base (318) of the sand trap(310) and the filling material (316) within a cavity of the sand trap (310). The retainer layer (329) is covered by the filling material (316) and as such it is substantially unexposed. The retainer layer (329) includes a plurality of spaced apart projections that can be formed from plastic, such as synthetic turf material. In certain embodiments, the filling material (316) fills the spaces between the projections. The retainer layer (329) can be substantially water impermeable and can cover majority of the surface area of the cavity. The retainer layer (329) can be positioned within the cavity at an angle (328) that is at least 10 degrees relative to the horizontal (300).Also, disclosed in the invention is the one or more methods for lining the cavity of a sand trap (322).
