When mixed with water, it transitions from a workable, plastic consistency to a rigid, waterproof plug in approximately one and a half minutes at +20°C. Once set, it exhibits high compressive and flexural strength within 30 minutes, ensuring the plug resists the shear forces of pressurized water. Because it contains no chlorides, it will not contribute to the corrosion of steel reinforcement. Additionally, it is certified to AS\/NZS 4020:2018, making it safe for sealing joints and cracks in contact with potable water.\u003c\/p\u003e\n\n \u003ch3\u003eNumbers that matter\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003e1.5-minute setting time (at +20°C):\u003c\/strong\u003e The exact physical window to mix, mold, and force the plug into the leaking cavity before hydration makes the material unworkable.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003e1-minute pot life:\u003c\/strong\u003e The maximum time available to prepare and place the mix, requiring the user to mix only what can be applied instantly.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003e17 N\/mm² compressive strength (at 30 minutes):\u003c\/strong\u003e Fast mechanical development to withstand structural and hydrostatic loads shortly after placement, rising to 46 N\/mm² after 28 days.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003e3 N\/mm² flexural strength (at 30 minutes):\u003c\/strong\u003e Early tensile capability to resist cracking under joint movement, rising to 9 N\/mm² after 28 days.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003e1.8 kg\/dm³ consumption:\u003c\/strong\u003e The material requirement to calculate coverage, where 1.8 kg of dry powder is needed to fill each litre of cavity volume.\u003c\/li\u003e\n \u003c\/ul\u003e\n\n \u003ch3\u003eWhere to use it\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003eInstant stopping of active water leaks, including water under pressure.\u003c\/li\u003e\n \u003cli\u003eSealing water leaks in basements, subways, and below-grade concrete structures.\u003c\/li\u003e\n \u003cli\u003eStopping leaks in above-ground potable water tanks.\u003c\/li\u003e\n \u003cli\u003eWaterproof sealing of rigid joints between concrete walls and floor slabs.\u003c\/li\u003e\n \u003cli\u003eWaterproof sealing of structural cracks and holes.\u003c\/li\u003e\n \u003c\/ul\u003e\n\n \u003ch3\u003eApplication procedure\u003c\/h3\u003e\n \u003cp\u003eFor sealing active water leaks, enlarge the crack or hole to a minimum of 2 cm wide and 2 cm deep, keeping the inner cavity wider than the exterior opening (dovetail profile) to mechanically lock the cured plug in place.
