{"title":"Injection","description":"\u003cp\u003eCracks in concrete and masonry can be of two types: active (moving) and passive (stable). Active cracks open and close with the structural load cycle — they should be treated with flexible injection material. Passive cracks have stabilized — they can be filled and bonded with rigid, high-strength material. Mixing the two is the most common mistake in injection.\u003c\/p\u003e\n\u003ch3\u003eWhat is injection?\u003c\/h3\u003e\n\u003cp\u003eInjection is the process of pressing liquid material into cracks, cavities, and capillaries at low pressure, aimed at restoring structural bonding, preventing water ingress, or blocking capillary moisture movement. The injection material hardens inside the crack and fills the space.\u003c\/p\u003e\n\u003ch3\u003eTypes of injection materials\u003c\/h3\u003e\n\u003cp\u003eEpoxy injection material: The highest strength crack filler. For structural re-bonding of passive, stable cracks — where the two sides of the crack need to be reconnected into a unified structure. Cured epoxy is stronger than the concrete itself. Not suitable for active, moving cracks.\u003c\/p\u003e\n\u003cp\u003ePolyurethane injection material: Available in flexible or foam-forming versions. For active, moving cracks and points of water ingress. PU foam expands upon contact with water and fills the cavity — providing immediate waterproofing. Cures in wet and water-exposed conditions.\u003c\/p\u003e\n\u003cp\u003eCement-based injection material (suspension): For filling masonry cavities, rock cracks, and capillaries. Low viscosity with good penetration ability.\u003c\/p\u003e\n\u003cp\u003eMicro-cement-based injection material: Finely ground cement that can penetrate narrower gaps where general cement suspension cannot.\u003c\/p\u003e\n\u003ch3\u003eCapillary moisture and injection\u003c\/h3\u003e\n\u003cp\u003eInjection used against capillary moisture in masonry (so-called horizontal moisture barrier injection) does not fill cracks but blocks the absorption path of capillary moisture. Silane or siloxane-based injection materials seal the capillaries of brick or stone masonry — moisture absorption stops, and the wall gradually dries out.\u003c\/p\u003e\n\u003cp\u003eBrowse our injection materials or request advice to select the appropriate injection system for the type of crack and the condition of the structure.\u003c\/p\u003e","products":[{"product_id":"kerakoll-kerabuild-epofill","title":"Kerakoll Kerabuild Epofill","description":"\u003cp\u003eVery fluid, low-viscosity two-component epoxy system for structural consolidation of jointed concrete elements.\u003c\/p\u003e\n\n\u003cp\u003e Kerakoll Kerabuild Epofill meets the performance requirements of the EN 1504-5 standard for injection products and the EN 1504-6 standard for anchoring products.\u003c\/p\u003e\n\n\u003ctable\u003e\n\n\u003ctbody\u003e\n\n\u003ctr\u003e\n\n\u003cth\u003e Wrapping\u003c\/th\u003e\n\n\u003ctd\u003e Bucket 0.66 kg + 0.33 kg bottle\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003cth\u003e Material requirement\u003c\/th\u003e\n\n\u003ctd\u003e ≈ 1.1 kg\/dm \u003csup\u003e3\u003c\/sup\u003e of the crack to be injected\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003cth\u003e Storage\u003c\/th\u003e\n\n\u003ctd\u003e ≈ 12 months\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\n\u003c\/tbody\u003e\n\n\n\u003c\/table\u003e","brand":"Kerakoll","offers":[{"title":"Default Title","offer_id":42827389174018,"sku":"10018, 10019","price":20550.0,"currency_code":"HUF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0635\/8027\/4946\/files\/kerakoll-kerabuild-epofill-szerkezeti-injektalo-es-lehorgonyzo-rendszerek-37363290702082.jpg?v=1702748540"}],"url":"https:\/\/www.masterworks.hu\/en\/collections\/szerkezeti-javitas-injektalas.oembed","provider":"Masterworks Hungary","version":"1.0","type":"link"}
