ELASTIC JOINT

EXPANSION JOINTS FOR WATERPROOFING MADE WITH BITUMINOUS MEMBRANES AND / OR PVC SUITABLE FOR ROOFS, TUNNELS, BASINS, ROAD PLANKS, ETC.

1) The ITALPROFILI® JOINT Art. 690 has the following conformation:
a – has two lateral bands with a width of mm. 150 grooved and under square at 35 ° 1 mm high, plus a series of perimeter holes to ensure perfect anchoring to the bitumen and / or bituminous membranes;
b – a central body with two thicknesses that acts as a gasket (joint), measuring height mm. 38, length ml. 25 (other measures on request).
2) The joint is extruded using a special and soft thermoplastic material (rubber type), compatible with bitumen and with modified bitumen membranes. This manufactured article thus made has excellent resistance to mechanical actions both in expansion and contraction even at low temperatures, it also has a high resistance to degradation caused by the sun, ozone and other atmospheric and chemical agents.
3) The JOINT Art. 692 has the same characteristics from Art. 690 with the variant of the side bands. In the latter they are smooth to facilitate the welding between the sheets and the joint with the PVC-P membranes.

N.B .: Operations to be carried out before laying the Elastic Joint.

1 – Spread the bulb facing upwards.
2 – Leave it in the sun for 15-20 minutes, this time is used to eliminate any abnormal creases caused by packaging and transport. In this way the joint returns to perfect condition and regains its initial shape.
