Product catalog summary
Introduction to Cork: Cork is the outer bark of the cork oak tree, known for its unique cellular structure that makes it lightweight, airtight, watertight, and resistant to various substances. It is sustainably harvested, renewable, and recyclable, making it an exceptional raw material.
Expandacork Features: Expandacork is a sustainable material used to fill expansion joints in concrete structures. It offers high durability, recovery, environmental resilience, and resistance to water, oil, and acid. It is easy to install, follows natural joint movements, and requires no maintenance.
Applications: Expandacork is suitable for various construction applications, including expansion joints, cover joints, simulated joints, contraction joints, curved joints, and metal element joints. It is ideal for structures with large thermal ranges.
Technical Specifications: Expandacork is available in two types, Type II and Type III, with different densities and compression properties. Type III self-expands in boiling water and shows no degradation after aging simulations. Both types comply with ASTM standards.
Installation and Performance: Expandacork's flexibility allows it to resist deformations from climate conditions, ensuring long-term performance in high-end construction projects. The Cork Inside seal guarantees the presence of cork in the product formulation.
Contact Information: Amorim Cork Composites provides contact details for their offices in Portugal and the USA for further inquiries.
Disclaimer: The brochure provides typical data and disclaims warranties, advising consultation for specific applications.

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 harvested...

Reinventing expansion joints Using cork to fill the gap-3

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 sealants....
