ECMAGROUT PU M 620
POLYURETHANE INJECTION RESIN TO STOP WATER LEAKS AND PERMANENT ELASTIC SEALING OF CRACKS BY ONE PRODUCT
ECMAGROUT PU M 620 is a two component, solvent and phthalate free, low viscosity, polyurethane injection system for the elastic sealing of cracks in concrete structures with a dual performance: a. In case water is present, it will form an elastic foam b. Incasethereisnowaterorthewaterhasbeenreactedaway,the material will form a flexible resin with the performance of a permanent sealing To stop water leakage ECMAGROUT PU M 620 could be used as a premix and injected as a single component and a flexible foam will be formed. To create a permanent elastic seal, the structure can be re-injected with ECMAGROUT PU M 620 using the same material and the same pump and the same packer.
• Dual function in one material - stopping water leaks & permanent sealing of cracks. • Can be pumped as one component premix or as two components. • Suitable for use in hot and cold climates. • Forms a flexible foam in contact with water. • Forms an elastic seal in absence of water. • Good adhesion to substrate. • Can withstand high hydrostatic pressures. • Non-toxic, suitable for use in contact with potable water
• ECMAGROUT PU M 620 is suitable to temporarily seal leaks in concrete structures and with a second injection of ECMAGROUT PU M 620 to permanently seal cracks and voids. • For injecting into leaking cracks in concrete or masonry. • Liquid retaining structures. • Sewage treatment plants. • Substructure concrete construction. • Leaking construction joints
