A hydrophobic system repels water and can work in dry or damp conditions but struggles with active flow. A hydrophilic system does the opposite — it is attracted to water, reacts with it on contact, and uses the moisture present in the crack to drive its expansion and curing process. In actively leaking concrete, hydrophilic is the correct chemistry.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eSika Injection-101H from Sika India Pvt. Ltd. is a hydrophilic single-component polyurethane injection grout engineered for active water leakage stopping and flexible crack sealing in concrete structures. When injected into a crack carrying active water flow, the hydrophilic PU resin reacts immediately on contact with water — expanding to fill the crack geometry, displacing the water, and curing to form a flexible, closed-cell foam seal that stops the leakage path completely. The reaction is driven by the water itself, meaning the wetter and more active the crack, the more effectively the system performs.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eOnce cured, the flexible foam seal accommodates minor structural movement without cracking or losing its watertight integrity — making it suitable not just for emergency leakage stopping but for longer-term flexible sealing of cracks and construction joints in below-grade concrete. The single-component formulation simplifies site application — no mixing required, consistent behaviour across variable moisture conditions, and reliable performance from port to port along the injection sequence.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eFor waterproofing contractors and structural repair specialists working on actively leaking basements, tunnels, underground structures, water retaining walls and below-grade concrete elements — Sika Injection-101H delivers the hydrophilic PU injection performance that active leakage demands.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eA construction chemical injection solution from Sika that works with active water conditions rather than around them — Injection-101H is the hydrophilic PU injection grout for leakage stopping and crack sealing where water is present and the seal must form immediately.\u003c\/p\u003e","brand":"Sika India Pvt.
