Engineered for low-pressure injection into mortar beds, this water-repellent treatment is ideal for combating rising damp in brick, stone, and cavity wall constructions. Cost-effective and non-flammable, it delivers long-lasting protection by penetrating deep into the masonry structure and lining capillaries to block moisture migration.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features \u0026amp; Benefits\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater-Based Formula:\u003c\/strong\u003e Non-flammable and easy to handle, ideal for sensitive indoor environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCost-Effective:\u003c\/strong\u003e High dilution rate (1:11.5) makes 2L concentrate yield up to 25L of ready-to-use solution.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEffective Against Rising Damp:\u003c\/strong\u003e Forms a continuous barrier in the mortar bed to prevent moisture transfer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow-Pressure Injection:\u003c\/strong\u003e Suitable for use in residential and heritage buildings with minimal disruption.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersatile Application:\u003c\/strong\u003e Effective in solid brickwork, stone, rubble-filled walls, and cavity walls.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFreeze-Tolerant:\u003c\/strong\u003e Unaffected by freezing; suitable for storage and use in cold conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eApplication Areas\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eRising damp in brick and stone walls\u003c\/li\u003e\n\u003cli\u003eRemedial damp proofing in existing buildings\u003c\/li\u003e\n\u003cli\u003eHeritage and conservation properties\u003c\/li\u003e\n\u003cli\u003eSolid, cavity, and rubble-core walls\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003ePreparation \u0026amp; Application\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSurface Prep:\u003c\/strong\u003e Remove skirtings, plasters, and damaged renders.
