Patent abstract
A preformed hinged foam sump for use on a flat roof includes two mirror image sides connected along the hinge which folds from an 8×8 structure to a 4×8 structure. Each of the mirror image panels includes a central panel which is a right isosceles triangle which slopes to the 90 degree angle of the right isosceles triangles. Each side includes two side panels which are sloped to the same point as the central panel and are also right isosceles triangles. The panels are bonded together to form each side which is connected by a flexible material or tape along the bottom side to allow the two sides to fold relative to each other to change from an 8×8 structure to a 4×8 structure and open up to an 8×8 structure for use on a roof surface.
