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 „ Readily 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. Concrete slab External walling and cladding Jointflex is used as a readily compressible, low load transfer joint filler in joints surrounding brick infill panel walling. It is also used as a gap filler, back-up strip and bond breaker to fill open joints in panel construction to provide support for joint sealants. 2 3 or 4 5 1 2 1. Jointflex 2.

Concrete beam Properties Form: Cross linked, compressible, closed cell foam sheet Colour: Grey Weathering: Very good weather resistance Recovery: Greater than 90% Water absorption: <0.02 g/cm³ Effects of fire: When tested to AS1503 Pt.3 Spread of flame index 0 Heat evolved index 0 Smoke development 4 index (smoke given off is non-toxic) Being a thermoplastic material, Jointflex will melt. It is combustible but rate of flame spread will be reduced when confined within a joint Nominal density: 25 kg/m³ Chemical resistance: Resists most common acids and chemicals Thermal conductivity: K factor 0.031 WMK 0°C March 2008
