PenePlug® is a rapid-setting, cementitious, crystalline-based compound designed for instant water-stopping in concrete structures. Its unique formulation allows it to block active leaks, even under high hydrostatic pressure, making it ideal for emergency repairs and critical water ingress points.

PenePlug® can be applied directly to wet or leaking surfaces, filling cracks, holes, or other openings in concrete to provide a durable, waterproof seal. Once hardened, it forms a crystalline structure that permanently prevents water from penetrating, while remaining fully compatible with other Penetron crystalline waterproofing products.
