Repairing concrete defects is a common activity on construction sites. Concrete defects, especially those embedded deeper inside the structure (honeycombs, voids, structural cracks, etc.), will – over time – compromise the impermeability, durability and service life of concrete. Therefore, it is crucial to prevent these issues in the first place or properly address them when they occur. Very often, these defects are detected when the structure is already in use – requiring a repair solution that is applied from the negative side.
In this context, the option of injecting PENETRON’s renowned and proven crystalline technology into concrete to eliminate water leaks resulting from honeycombs, voids and cracks in the structure, is an effective and permanent solution.
PENETRON INJECT, is a highly effective, two-component, crystalline injection grout to seal cracks and fissures by filling hollow spots and voids in the concrete. The extremely fine particle size of the ingredients (for a very low, water-like viscosity) allows PENETRON INJECT to penetrate even fine hairline cracks in concrete and rock fissures and seal them.
Injected under pressure deep into the concrete, PENETRON INJECT displaces any existing water, filling voids with a crystalline micro-cement and immediately providing stability and strength to the repaired area. From here, the PENETRON crystal growth continues in the presence of moisture, as these areas usually contain a lot of water or moisture. Any remaining voids are sealed, stopping the flow of water.
PENETRON INJECT restores the structural integrity of the repaired area and, unlike conventional injection materials like polyurethane and epoxy grouts, does not debond, crack and potentially allow water to leak through again.
The unique self-healing abilities of PENETRON INJECT ensure that any potential passageway for water in the defective patch is sealed. Preventing water from entering the concrete improves corrosion protection of the reinforcement steel, enhances durability and ultimately extends the service life of the structure.
In combination with our world-class PENETRON repair system (PENETRON, PENECRETE MORTAR, PENEPLUG), PENETRON INJECT provides a total solution designed to tackle even the most complicated repair situations.
