Optiflex 620

A twin pack polyurethane compound designed to be used as a joint filler in floors, where movement is limited and reinforcing of the edges of the joint is required. Due to its good compressive properties it helps reinforce the joint against the effect of wheeled traffic. But at the same time its poor tensile strength ensures that movement at the joint faces, particularly those caused when the joint opens, does not cause spalling of the concrete.


Product uses

  • As reinforcing joint filler for joints in internal floors, designed to handle heavy hard-wheeled traffic.
  • Recommended for use in industrial flooring applications where “joint spacing” is typically a problem.



  • Highly compressive and flexible.
  • Resistant to various chemicals.



Dependant on depth and width of joint.
