Shutting out water leaks from concrete joints! Underground waterproofing technology that supports structures.
The "Pingraut PW System" is a preventive maintenance method that replaces traditional water-stopping boards and water-expanding seals by embedding hollow members (PW hoses) in the concrete joint in advance. Approximately four weeks after the completion of the subsequent concrete work, a water-stopping material, hydrophilic one-component polyurethane resin "NL Paste," is injected to reliably fill the voids in the concrete (water leakage) and achieve water-stopping at the joint (Patent No. 5284888). 【Features】 ○ Underground water-stopping technology that supports long-lasting structures ○ Reliable water-stopping with simple construction ○ Can fill even fine gaps ○ Excellent adhesion to concrete surfaces ○ Superior durability For more details, please contact us or download the catalog.
