SITREN® Selfheal 455 is a formulation in powder form based on natural microbes, nutrients and surface active ingredients.
SITREN® Selfheal 455 is a self-healing agent to be used for the manufacturing of ready-to-use concrete and precast concrete elements.
The concrete has to be in contact with moisture and/or water. Typical applications are groundwater retaining basement walls, water reservoirs, tunnels, bridges, pipes, damps etc.
Benefits & Advantages:
• Repeated healing of cracks and pores
• Densified concrete and mortar matrices lead to higher compressive strength
• Lower water penetration – improved freeze-thaw resistance
• Saving cost and time for building repair and maintenance
• Elongation of the lifetime of a building reduces concrete waste and CO2 emissions
• Smooth surface finish and excellent workability proper ties
