A commonly used well has been a plastic design of flat parts that snap together to form the walls and steps. A problem lies in its durability; its ability to hold back the heavy earth and water.
RockWell window wells are a one-piece, rigid construction that will not collapse from backfill or allow water to leak through the well walls. They're UV stable, rust and rot proof, and stand up to extreme temperatures.
