Cork, an exceptional raw material Cork comes from the bark of the cork oak tree (Quercus Suber L). It is a plant tissue, 100% natural, which covers 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 known as “nature’s foam” due to its alveolar structure. Cork is lightweight, airtight, watertight, resistant to acids, fuels and oils, and impervious to rotting. Cork is sustainably harvested by specialized professionals...

EXPANDACORK, Expansion Joints 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...

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. STANDARD DIMENSIONS Filling the Joint Type II Filling the Joint Type III Filling the Joint Type II Filling the Joint Type III 50% of initial thickness with a load between 0.35MPa and...
