Abstract
Abstract A liner assembly ( 222 A) for a sand trap ( 10 ) having a perimeter ( 12 ) that defines a cavity ( 13 ) and a substrate ( 18 ) within the cavity ( 13 ) includes a first layer ( 230 A) and a second layer ( 232 A). The first layer ( 230 A) is positioned on the substrate ( 18 ) and can be formed from a substantially water-permeable material. The second layer ( 232 A) can be formed from a substantially water-impermeable material and is applied to the first layer ( 230 A). The second layer ( 232 A) can be applied to the first layer ( 230 A) as a liquid, such as a polyurea material. In one embodiment, at least one of the layers ( 230 A, 232 A) extends within the substrate ( 18 ) at least partially outside the perimeter ( 12 ) of the sand trap ( 10 ). The second layer ( 232 A) can include an aggregate material that is integrally formed as part of the second layer ( 232 A).
