MaxumStone Retaining Wall Units are large wet-cast concrete units with a horizontal and vertical hollow core. The open core make the units easier to ship and handle in the field and allows for vertical internal drainage, minimizing the effects of hydrostatic pressures behind the walls and facilitates design options for \u2018rapid draw-down\u2019 in the case of flooding. Wet-cast MaxumStone units provides a durable, 4000 psi (27.5 MPa) concrete that is resistant to freeze-thaw degradation in areas of repeated freezing and thawing in saturated conditions. Designing for water conditions requires the designer to investigate several design options.<\/p>\r\n\r\n\r\n\r\n
MaxumStone units are often used as sidewalls for drainage channels. In flowing conditions the roughness of the block and the Manning\u2019s N value are important to flow conditions.<\/p>\r\n\r\n\r\n\r\n
