Concrete Expansion Joint Sealant

JointSeal®
Polyurea SL High Strength

JointSeal® Polyurea SL High Strength is a two-component, solvent-free pure polyurea elastomer engineered for demanding joint sealing applications where exceptional durability, flexibility, and rapid return to service are required. This high-performance sealant delivers outstanding abrasion resistance, impact resistance, moisture protection, and long-term elasticity while maintaining excellent performance under heavy traffic and severe environmental conditions. Unlike hybrid polyurea systems, it is based on pure polyurea technology, providing uncompromised performance and ultra-fast curing characteristics.

Available in 40L and 400L spray system packs and 1.5L cartridge systems.

Intended Uses

JointSeal® Polyurea SL High Strength is specifically designed for heavy-duty movement joints, expansion joints, and waterproofing applications subjected to continuous traffic, mechanical loading, impact, abrasion, and environmental exposure. The rapid-curing pure polyurea technology allows facilities to return to operation quickly while providing a highly durable and flexible seal capable of accommodating substrate movement. It is particularly suited to industrial flooring systems, parking structures, bridge decks, and infrastructure projects where traditional sealants may not offer sufficient durability or rapid curing performance.

Typical Applications:

  • Industrial floor expansion joints
  • Warehouse flooring joints
  • Manufacturing facility floors
  • Logistics and distribution centres
  • Parking deck joints
  • Multi-storey parking structures
  • Bridge deck joints
  • Infrastructure movement joints
  • Concrete expansion joints
  • Heavy-duty workshop floors
  • Aircraft hangar flooring
  • Port and marine infrastructure
  • Mining facilities
