GC Alloy is a fast-setting grey cementitious alloy developed for stopping active water leakage and repairing selected leakage points in concrete and masonry surfaces.
Remove loose concrete, dust, dirt and weak material around the leakage point. Open the affected area sufficiently for proper treatment.
Mix only the amount of GC Alloy that can be applied immediately. Because the material sets quickly, prepare it in small workable quantities.
Press the prepared material firmly into the active leakage point, crack or opening to create direct contact with the affected surface.
Hold the material firmly in position until it sets. GC Alloy is designed for rapid setting, making it suitable for urgent leakage treatment.
Important: GC Alloy is a fast-setting material and may set within approximately 1–2 minutes depending on site and environmental conditions. Prepare only a small amount at a time and apply immediately. For major leakage or structural cracks, technical inspection is recommended.
