Zip Block (ZB) is a water-proof, one-piece extruded EPDM elastomeric seal with integral nosings, which is bonded to the substrate with high strength epoxy adhesive.
Zip Block is much stronger than traditional elastomeric concrete systems providing a problem-free long-term joint solution.
- Joint Width: up to 100mm
- Horizontal: up to ±50mm
- Vertical: up to ±15mm
- Lateral: up to ±15mm
- Load Capability: 1000kg point load
Why Zip Block (ZB)
Winged seals with elastomeric concrete fail regularly.
Wheeled impact causes hairline cracks in elastomeric concrete in typical applications. Through further wheeled impact, cracking becomes more severe until the seal’s wing pulls away.
A one-piece EPDM rubber system.
The shoulder of the Zip Block is substantial enough to withstand wheeled impact (even snow ploughs), regardless of the condition of the slab edge below. ZB’s epoxy bond holds under constant deflection and temperature changes.
Zip Block has been subjected to rigorous testing, including rolling loads of 1,350kg per wheel, with simultaneous vertical slab deflection; sub-zero temperature testing, including several freeze-thaw cycles; and all applicable ASTM cycling tests. At 35,000 cycles the seal exhibited no wear or tear from the rolling load.
