Abstract: A method and related apparatus for forming a sluiceway adjacent a wall and cement floor includes a sluiceway form made from a generally rectangular sheet of biodegradable material having a number of generally parallel fold lines to define a plurality of contiguous sluiceway panels disposed inwardly of opposite marginal portions of the sheet which are folded into face-to-face relation with each other to form an elongated sluiceway form having a body portion defined by the sluiceway panels and a tab defined by the marginal portions projecting from the body portion and extending along the entire length of the body portion. The sluiceway is formed by positioning the sluiceway form adjacent the wall with at least a part of the body portion below the level of the grade and the free edge of the tab extending in a generally parallel relation to the grade level. The tab is secured to the wall and the concrete floor is poured with the sluiceway form in position.
