Abstract (en)
[origin: EP0743400A1] The drain cover (4) is held level with the road surface in a lipped metal ring (2) which is itself held over a concrete support base ring (1). Elastomer padding (6) between the metal ring and the base ring hold the metal ring while a concrete levelling layer (10) is placed under the metal ring. The elastomer pads are positioned around the base ring and can be made of a thermoplastic material. When the road surface is raised the metal ring is raised to align the top edge with the new road level and is held by the elastomer padding while additional levelling concrete is travelled under the metal ring.
