<p>The shaped concrete panels are designed for assembling into a combined group, to serve as underlay base for the storage of refuse which is being kept so that it can be converted into compost. The longitudinal sides of the panels are tongued and grooved for joining together. Inside the panel there is a continuous channel (7), running parallel to the longitudinal sides (4, 5), and one or more recesses (8, 9) lead off from this, on one end face, into the area of the top lateral edges. The lateral edges (6) on the surface may be bent back at an angle of 45 deg., with two upwards sloping channels emerging in this area.</p> |
