FIXED PAVING SUPPORT FOR PREFABRICATED SLABS

EXPANSION JOINTS FOR BITUMINOUS OR PVC-P WATERPROOFING MEMBRANES FOR USE ON ROOFS, TUNNELS, VIADUCTS ETC.

  1. The ITALPROFILI® Art. 690 has the following characteristics:
      • two 150 mm lateral wings with 35°angled ribs at 1 mm in height and a series of slots along the outside edge to ensure sound anchorage to the bitumen and to the bituminous membrane;

     

    • a central body with 2 different thicknesses which preform both as an expansion joint and a seal and is 38 mm x 38 mm x 25 metres in length.

     

  2.  The joint is extruded using a specially stabilized thermoplastic but “rubbery” type material which is compatible with bitumen and with bituminous membranes. This material has a high mechanical resistance both in expansion and contraction, also at low temperatures and is highly resistant to UV, ozone and other chemical and atmospheric agents.
  3. Art. 692 has the same characteristics as Art. 690 with the exception of the lateral wings which are smooth to facilitate welding to PVC membranes.

NOTE: Preparatory work before installing the elastic joint.

    •  Lay out the joint with the bulb facing towards the top.

 

  • Leave to relax for 15-20 minutes so that any creases or similar in the materials caused during packaging or shipping are eliminated. This enables the joint to return to its natural state and return to its initial shape.
