Cork Expansion Joints

The special quality composition cork in our expansion joints is weather resistant and easy to compress – 150 Ibs/in2, giving it 50% compression.

Applications include:

  • Indoor construction – Cork expansion joints help address the expansion of hard surface flooring.
  • Outdoor construction – Cork expansion joints help mitigate the expansion of concrete constructions, including roads, bridges, dams, tunnels,  airports, and more.

Advantages of Cork for Expansion

  1. Cork is the Perfect Sealant
    Our cork material provides a perfect sealant between concrete sections, which expand and contract under different weather conditions.
  2. Cork is Easy to Maintain
    Cork expansion joints also do not require constant maintenance, since dirt, stones and other foreign materials cannot enter to damage the joints.
  3. Cork Does Bulge Under Compression
    Cork does not bulge when three of its four sides are compressed. Practically speaking, this prevents a bumpy car ride on roads made of concrete blocks, for example.
