<p>Implementations of the present disclosure provide an environmentally resistant structural member for use in areas exposed to water or other environmental elements. The structural member includes a core member and a polymer layer. The core member has an environmentally sensitive composition wherein extended exposure to the environmental element causes degradation of the core member. The core member includes at least one surface, such as a bottom and side surfaces. The surface is configured for positioning in the area exposed to the environmental element. The polymer layer has a molded shape and covers the surface so as to seal the surface of the core member against exposure to the environmental element.</p> |
