Jointflex is also used as back-up strips for elastomeric sealants placed in joints of concrete floors subject to foot traffic and light wheel loads. For joints subject to heavy loads or joints in water retaining structures Stiffjoint should be used (see separate Technical Data Sheet). „ Back-up/bond breaker strip to support sealants „ Bridge decks, abutments, pier hinge joints „ Brick and blockwork in building superstructures Advantages „ R eadily compressible „ Low load transfer „ Easily cut on-site „ Excellent recovery after compression „ Non-absorbent „ Rot proof „ CFC free Description Jointflex is a flexible, readily compressible, closed-cell polyethylene joint filler supplied in sheet form and in rolls of rectangular sections. Jointflex is available in a range of widths and thicknesses to suit common applications and can be pre-slit to assist in forming a slot to accept joint sealants. Jointflex can also be supplied with a self adhesive backing. Design Criteria Trafficked surface expansion joint 1 3 2 1. Jointflex 2. Suitable joint sealant 3.
