<p>A plastic building block may be made from recycled scrap polymer material and may be injection moulded. The block may have a hollow inner core into which an insulation material may be fitted. A series of projections or fingers may project from a lower face of the block and may engage with a corresponding series of grooves or slots to facilitate engagement of a series of block to create a wall. The outer surface of the blocks may be patterned to simulate wallpaper, bricks or stone finish. The bricks may be made of a sound deadening and or fire resistant material.</p> |
