Abstract:
1. A liftable support platform adapted for the dual role of supporting a layer of natural turf or a layer of artificial turf and infill above a foundation, the platform comprising: a structure moulded in foamed plastics in two halves joined to form a square or rectangle, the join being about a diagonal, the sides of the structure being between 2250 and 2400 mm in length, the structure further having edge retainers fixed to the sides of the structure, the edge retainers having an upper edge above the top surface of the structure to define an enclosure to prevent escape of the layer of turf from the top surface; a slot across adjacent edges of each corner of the structure; and members which are accommodated in said slots and which are adapted to extend and join the structure to similar adjacent structures in abutting contact and to prevent each corner of the structure from arching upwardly in use relative to the associated corners of the similar adjacent structures.
