[Column] What is the "secondary water stop material" for expansion joints? An overview of its purpose and types.

Secondary water stop materials for secondary water stopping! An explanation of the purpose and an introduction to products from various manufacturers.

The lifespan of a bridge is greatly affected by the water-stopping performance of the expansion device. While it is natural to require the water-stopping performance of the main product (primary water stop), recently there have been increasing cases where the installation of "secondary water-stopping materials" is requested in case the primary water-stopping performance of the main body deteriorates. Therefore, I would like to explain the "purpose" of the secondary water-stopping materials related to the water-stopping performance of the expansion device and provide "introductions to products from various manufacturers." *For detailed content of the column, please refer to the related links.

[Column] Explanation of the Reasons and Types of Water-Stopping Materials for Expansion Devices

[Column] Explanation of the Reasons and Types of Water-Stopping Materials for Expansion Devices

A detailed explanation of the role of the water-stopping material in the expansion and contraction device and the types of water-stopping materials.

One of the functions required of expansion joints is water-tightness. High water-tightness not only extends the lifespan of bridges but also reduces lifecycle costs, providing many benefits. However, the water-stopping materials that fulfill this role are very susceptible to damage and are a major cause of leaks. Therefore, various measures are being implemented by manufacturers to maintain the water-stopping materials for as long as possible. This article explains the role of water-stopping materials in expansion joints and the types of water-stopping materials. *For detailed content of the column, please refer to the related links. For more information, feel free to contact us.*

【NETIS Plus AC-170027-P】Bitograut-UG

【NETIS Plus AC-170027-P】Bitograut-UG

Complete waterproofing under previously deemed impossible adverse conditions is now possible.

Our company employs the "Bitogrout-UG Injection Method," which completely seals leaks in underground structures and ensures long-term stability through the formation of external waterproofing. We drill a penetration hole in the back surface of the concrete structure and inject a water-based emulsion resin from there towards the inside. The resin permeates and backflows through various leak paths, forming a new waterproof layer. Additionally, this method allows for water stoppage over a long period of 10 to 25 years (with proven results), significantly reducing maintenance costs. 【Features】 ■ Enables water stoppage for a long period of 10 to 25 years (with proven results) ■ Low maintenance costs ■ Possesses stability performance that can be referred to as "post-construction external waterproofing" ■ Strong adhesion ensures long-lasting water stoppage effects ■ No volume reduction or permeability after curing *For more details, please refer to the PDF document or feel free to contact us.
