Expandacork - Type II.
Amorim Expandacork
Absorbing expansions and the contractions inherent to concrete buildings
Designed to fill the gaps left between concrete slabs, Amorim Expandacork products absorb the vibrations, expansions and contractions caused by thermal variations in different construction systems. The joint fillers allow the movement of structures without causing damage and ensuring these spaced are filled.
Amorim Expandacork's unique flexibility enables its easy deployment and also its capacity to resist without any deterioration the continuous deformations caused by different climate conditions. Amorim Expandacork materials correspond to a long term compromise between performance, durability and mechanical resistance required on the high end projects of the construction industry.

Long term durability with easy installation
The use of Amorim Expandacork will provide a positive contribute allowing the construction elements to contract and expand, consequentely avoiding cracks and lowering its maintenance ratio.
Selecting the right material to apply to expansion joints is critical to ensure safety and durability in construction. Cork-based solutions, given the natural properties and benefits of this material, guarantee a sustainable and high technical performance response for buildings and large public works over time.
