Expansion Joints

Uses of Cork Expansion Joints

Cork expansion joints help address the expansion of hard surface flooring, as well as outdoor concrete constructions of roads, bridges, dams, tunnels and airports, etc. Our special quality composition cork is weather resistant and easy to compress – 150 Ibs per sq. in. giving 50% compression.

Advantages of Cork for Expansion

This cork material provides a perfect sealant between concrete sections which expand and contract under different weather conditions. Cork expansion joints also do not require constant maintenance, since dirt, stones and other foreign materials cannot enter to damage the joints.

Beyond its ability to seal, cork does not bulge when three of its four sides are compressed. This prevents a bumpy car ride on roads made of concrete blocks, for example. This is yet another important advantage or cork over other materials.
