Cork, an exceptional raw material Cork is the outer bark of the cork oak tree (Quercus suber L.), the 100% natural plant tissue covering the trunk and branches. It consists of a honeycomb-like structure of microscopic cells filled with an air-like gas and coated mainly with suberin and lignin. One cubic centimeter of cork contains about 40 million cells. Cork is also known as “nature’s foam” due to its alveolar cellular structure. It has a closed-cell structure making it lightweight, airtight and watertight, resistant to acids, fuels and oils, and impervious to rot. It is sustainably...

Using nature to fill the gap Designed to fill gaps left between expansion joints in concrete structures, Expandacork products absorb vibration, and allow for expansion and contraction caused by heat in different construction materials. Dilation joints enable the movement of structures without causing consequent damage and ensuring that these spaces are always filled. They are commonly applied in concrete, brick and block work, tunnels, water storage and supply systems, aqueducts, dams, airport runways and taxi tracks, concrete roads and parking areas or even as a backup support for...

The various types of joints used in construction Expandacork products are suitable for a broad variety of applications: Expansion joint Contraction joint Cover joint Curved joint Simulated joint Metal element joint

The right choice for large thermal ranges The unique flexibility of Expandacork products allows them to be easily installed with the capacity to resist continuous deformations caused by different climate conditions. Since Expandacork does not deteriorate, the joint remains appropriately filled. Expandacork materials offer long-term performance required on high-end projects within the construction industry.
