Newton Hydrocoat 313-WP Waterplug

313-WP – Fast-Setting, Polymer Compound for Instant Leak Sealing

313-WP is a rapid-setting, polymer-modified compound designed to instantly stop running water and seepage through masonry or concrete substrates. This non-shrink, fibre-reinforced material expands slightly upon application and sets in just 2 minutes, becoming even harder and more resistant when subjected to water pressure.

With exceptional durability, 313-WP remains effective for the lifespan of the structure and requires no specialist tools or expertise, making it ideal for emergency leak sealing in construction, repair, and waterproofing applications.
