In repairs that do not require chipping, you can prolong the lifespan of the bridge without damaging the deck and reduce maintenance costs!
The "DIA Free Joint" is a bridge expansion joint device that excels not only in safety and soundproofing during operation but also in ease of installation and maintenance, as well as cost-effectiveness. It consists of a separation structure made up of three components: a receiving base attached to the deck, a receiving plate installed on top of the receiving base, and a surface rubber with numerous diamond-shaped holes. Although these components are separate, they function together as a cohesive unit, demonstrating excellent performance. Additionally, it flexibly responds to various conditions at each site and is designed to minimize noise and debris during repair work, taking environmental considerations into account. 【Features】 ■ Protects the deck ■ Comfortable driving ■ Safe driving ■ Environmentally friendly ■ Cost reduction ■ Compatible with both pre-installation and post-installation methods *For more details, please download the PDF or feel free to contact us.
