Ready-to-use powder—just add water. Non-toxic and chloride-free—safe for potable water structures. Excellent adhesion to concrete, masonry, metals, PVC, HDPE etc. Low exotherm (less heat during curing), similar thermal expansion as concrete.Q1. What kind of leaks can this stop?It can stop negative‐pressure leaks through cracks, joints, gravel pockets, casting joints etc.—even under running water. Q2. How fast does it set and become effective?At around 27 °C, it begins to harden in ~2-3 minutes. Quick strength gain ensures leak stops fast. Q3. How is the surface prepared before sealing?Clean area—remove loose materials, oil, grease etc. Widen leak point in "dovetail" shape (~20 mm) to allow better bonding. Wet the surface if very dry. Q4. How much material is needed?Depends on volume of leak / cavity. Since setting is very fast, mix small quantities at a time that you can apply immediately. For 1 kg bag, small area patch; for big leaks you may need multiple bags.Q5. Can it handle high pressure or lots of water flow?Yes—but for very high pressures, sometimes drill relief holes around the leak, or using supporting plugs, then apply the mortar. Larger bonding surface helps. Q6. Is it safe for potable water or areas that carry water later?Yes—it's non-toxic and chloride free. Once cured, it can be used in water tanks, etc. Q7.
