Abstract: A form for receiving a filler material to create an island is provided. The form has a substantially continuous wall having an outer surface and an inner surface. The wall has a first side and a second side opposite the first side. The inner surface forms an enclosed chamber for receiving the filler material. A first support is removably attached to the inner surface of the first side of the wall and a second support is removably attached to the inner surface of the second side of the wall. A brace is disposed between the supports, wherein the brace removably engages the supports.
