Elastoproof Prefabricated Corners

Ensure effective detailing of the Elastoproof Jointing Band applications at critical 90° and 270º corner intersections.

The Elastoproof Prefabricated Corner Sections ensure effective detailing of the Elastoproof Jointing Band applications at critical 90º and 270º corner intersections. Maintaining the “flexible zone” to ensure a seamless and elastic seal at joint intersections, Prefabricated Corner Sections overcome many difficulties when detailing membranes at volatile areas, providing a superior alternative to methods of multilayered membranes, reinforcement layers, bond-breaking tapes, foam rods, sealants and welding.

Features & Benefits

  • Ensures a seamless elastic seal at joint intersections
  • Waterproof and a vapour barrier
  • Fast effective application
  • Enables 100% elastic recovery when exposed to movement
  • High strength and excellent tear resistance
  • Long-term sealing protection in volatile areas
  • Eliminates lapping and bonding of fabrics at critical corner areas
  • Compatible with all Gripset membranes


Suitable for commercial, industrial, and residential applications

Waterproofing Uses

For use as a bond breaker in the following critical areas:

  • Internal Corners – designed for 90º corners to form a seamless seal over corner intersections
  • External Corners – designed for 270º corner sections to form a seamless seal between wall intersections. Ideal for pillars, columns and outside returns
  • 3D Corners – designed for 90º corner sections with a vertical upstand for sealing wall/floor and wall/wall intersected corners. Suitable for large open joints, particularly pre-cast concrete or corner areas prone to high movement
