Application Process

Fast & Simple Leakage Treatment

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.

01

Prepare the Area

Remove loose concrete, dust, dirt and weak material around the leakage point. Open the affected area sufficiently for proper treatment.

02

Prepare GC Alloy

Mix only the amount of GC Alloy that can be applied immediately. Because the material sets quickly, prepare it in small workable quantities.

03

Apply to Leakage Point

Press the prepared material firmly into the active leakage point, crack or opening to create direct contact with the affected surface.

04

Hold Until Set

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.

Gray cementations Alloy is mainly composed of Silicon Dioxide, Aluminum oxide, Magnesium Sulfite, Maganese Tetraoxide, Sulfar Trioxide, copper sulfoaluminates, copper sulfite, copper metaborate, catalyst, auto catalyst and many more etc. Excellently effective to stop running water from leakages, cracks, honey combs, pre-constructed faulty basement; sets within 1.5-3 minutes through polymerization and alloy forming processes joining with the previously casted concrete as a single much of high strength like concrete. Gray Cementitious Alloy is excellently effective in stopping running water from leaks, cracks, honey-combs, etc. at per-constructed faulty basements, water tanks, and similar structures. It sets instantly (1.5 to 3 minutes) to stop running water through polymerization and alloy forming processes joining with the previously cast concrete as a single mass and after 7 days or more achieves high strength like concrete. Paste of Gray Cementitious Alloy can be used for any concrete repair including water retaining structures and other places. It gives monolithic action without shrinkage where expanded concrete is needed.
