Level compensation and noise reduction for deck structures
- Compensates for substrate irregularities
- Reduces parasitic noise and vibrations
- Improves the acoustic comfort of the deck
- Limits galvanic corrosion phenomena
- Simple and quick solution to implement
Technical specifications
Grad® rubber strip are designed to compensate for small level differences and improve the acoustic comfort of decks.
Made of agglomerated rubber with a self-adhesive side, they easily integrate under the rails to absorb substrate irregularities and eliminate parasitic noise related to contact between materials.
They also play a protective role by limiting galvanic corrosion phenomena between metal structures and aluminum rails.

Significantly reduces parasitic noise and improves acoustics.
ADAPTABILITY
Allows precise level adjustment thanks to the different thicknesses available.
PROTECTION
Limits the risks of galvanic corrosion and protects interfaces between materials.
Instructions for use
The Elastomer strip is positioned under the rails when they rest directly on a rigid support, or interleaved between the rail and a metal beam. It allows absorbing substrate irregularities while avoiding galvanic corrosion phenomena related to contact between different materials.
In the case of a deck with a slight slope, when the rails are installed perpendicular to the direction of flow, it is recommended to leave a space of approximately 5 cm every 5 m to ensure efficient rainwater drainage.
