People hear have used shingles for fill like that here. U could buy them by the dump truck load and they would be cut in strips. And yes shingles will still let water up threw and down threw them. Has anyone seen a flat roof with shingles. The answer is no. Because shingles only shed water if they are on a pitch. Hellooooo anyone ever seen water run up hill. Haha
