Expandacork - Type II
Expansion Joints
Absorbing expansions and the contractions inherent to concrete buildingsDesigned to fill the gaps left between expansion joints in concrete slabs, 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.
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. Expandacork materials correspond to a long term compromise between performance, durability and mechanical resistance required on the high end projects of construction industry.

|---|---|---|
| Compression | 50% of initial thickness with a load of between 0.35 MPa and 10.35MPa (50 to 1500 PSI) | |
| Recovery | 90% of original thickness following 50% compression, EXPANDACORK attains 95% | |
| Extrusion | There is a maximum extrusion level beyond the joint of 6.35mm (1/4'') when subject to 50% compression | |
| Resistance to HCI | Submerged into boiling HCI, Expandacork does not desintegrate | |
| Expansion | n.a. | Submerged into boiling water for the period of one hour, Expandacork - self expanding cork type III expands by less than 40% of its original thickeness |
| Dimensional Variation | n.a. | Expandacork - self expanding cork type III does not display any sign of degradation even after the simulation of ten cycles og ageing and continues to complete seal the joint |
| Storage | Expandacork should be conserved on its original packaging and in a dry place through its application | |
