Ivar 3D

IVAR is a waterproofing system for foundations, basements, terraces, roofs, underground or multi storey carparks. IVAR can easily be applied on the concrete substrate by torching the overlap or fully bonded. The composition of the product provides a durable adhesion, even on uneven ground. The product is unique in its kind because it has no reinforcement, so it automatically configures to the subsurface. Therefore, it is very suitable for making expansion joints, recesses and corners, such as pile- heads. The application is much less time-consuming than products which contain a carrier.

Major Features

  • 5 mm thickness.

  • 1600 % elongation with full recovery.

  • No reinforcement inside the membrane.

  • High penetration resistance.

  • Self-healing after puncturing.

  • Easy anchoring and joining to concrete structures.

  • 3D mouldable, which makes detailing work (corners, piles etc.) safe and fast.

  • Easy application: once unrolled, the overlap can be immediately sealed by propane torch.

  • Takes any shape without need for cutting.

  • No fillers added to the compound.

  • One layer of 5 mm IVAR is superior to two or more layers of reinforced membranes.

Method of Application

  • The product rolling is carried out to have the foil in contact with the concrete when directly unrolled (foil face exterior of the roll).

  • The over laps are welded with propane gas torch/dry heat air and roll pressed. For tanking application, the longitudinal overlaps are 100 mm edge and the end overlaps are 150 mm edge.

  • No additional cover strip is necessary. Optionally the membrane can be applied fully bonded for instance on difficult details and vertical walls.
