Description/Design

For joints with edge protection

Description
Our compression profiles are rubber sealing sections that absorb movements and provide comfortable traffic. The benefits of the system depend on the mechanical properties of the sealing section, proper housing design and execution and quality of the edge guard and paving in the vicinity of the joint.
Design
The cross section of these profiles is reinforced bees panel, a design that allows maintaining a suitable pressure against the walls of the joint, without causing permanent deformation. The profiles are used in serrated or pre-shaped joints, being very important a correct joint geometry and dimensions of the joint in the structure to ensure correct performance.
Drains/waterproof
Drains
In black pavement, the inclusion of effective drainage in the edge protector area affects decisively in the life of the joint. In this way, pumping effect and subsequent wear of the asphalt layer is prevented.
Waterproof
Properly installed compression profiles provide a sufficient degree of waterproof in most cases. However, when waterproof is a mayor need, as in car parks, additional or alternative Transflex systems must be designed.
The compression profiles J-150, J-250 J-350 y J-450 absorb movement ranges of 18, 25, 42 and 50mm.
