It is possible to minimize damage in the reinforcement core material section! Water resistance is improved, and product weight reduction can be achieved.
We would like to introduce the "Flexible Joint Rubber Method," which can be applied to connections with joint trenches, culverts, underground passages, waterways, manholes, and pipes. The base material is polymer, using weather-resistant chloroprene rubber. It improves water pressure resistance, reduces the weight of the product, and prevents internal swelling, without compromising the internal cross-section. 【Features】 ■ Uses weather-resistant chloroprene rubber as the base material. ■ By laminating a special nylon woven fabric as a reinforcing core material in the center: - Water pressure resistance is improved, and the product's weight is reduced. - Internal swelling is prevented, and it does not compromise the internal cross-section. - Even if surface damage occurs, it is possible to minimize damage at the reinforcing core material. ■ Applications include connections with joint trenches, culverts, underground passages, waterways, manholes, and pipes. *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Other Features】 ■ Flexible Joint Method (Repair Method) - Uses weather-resistant chloroprene rubber or ethylene propylene rubber as the polymer base material. - A post-installed waterproof flexible joint that fixes the expansion rubber to the surface of the existing concrete structure at the joint area using anchor bolts and a pressure plate. ■ Santak Rubber Waterproofing Board - A waterproofing board rich in followability and waterproofing properties, used for joints between precast and cast-in-place sections. - The center valve is of the uncut type, allowing free deformation in response to displacements of the concrete structure, preventing undue stress on the waterproofing board. *For more details, please refer to the PDF materials or feel free to contact us.
