TWO COMPONENT, LOW VISCOUS, COMBINATION POLYURETHANE INJECTION SYSTEM TO STOP WATER LEAKAGE ALONG WITH PERMANENT & ELASTIC SEALING OF CRACKS.    Description:- 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. In case there is no water or the water has been reacted away, the material will form a flexible resin with the performance of a permanent sealing Mixing ratio 2:1 in volume 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.   Advantages:- • Dual function in one material – stopping small water leaks and a permanent sealing of cracks. • Low viscosity allows full penetration in fine cracks and voids • Suitable for hot and cold climates • Good adhesion to dry, moist and wet concrete or masonry. • Forms a flexible foam in contact with water • Forms an elastic resin in the absence of water • Can withstands high hydrostatic pressures as the cured resin is impermeable to water • Can be pumped as a 1 component premix because of the long pot life; therefore, a single component injection pump can be used • The cured material is non toxic • The system is suitable for use in contact with potable water.    USES:- • Sealing leaking cracks to create a permanent sealing of the crack with one material, machine and packer • For injecting into leaking but also dry cracks in concrete or masonry. • Leaking construction joints • Water retaining structures • Sewage treatment plants • Substructure concrete constructions.   Mixing:- • Due to the long pot life for the ECMAGROUT PU M 620 it can be pumped as a single component pre-mix • Pour the content of the Part A into a CLEAN, DRY plastic bucket. • Add the required amount of Part B • Mix thoroughly manually or with a slow speed mixer (stirrer fixed to a drilling machine) for about half a minute until the mix is homogeneous. Injection Process:- • Polyurethanes are water sensitive and to avoid pump and hose blockages they should be flushed with a suitable cleaning agent like ECMACLEAN prior to using the polyurethanes • The ECMAGROUT PU M 620 should be injected using a injection machine having a covered reservoir to avoid moisture coming into the pre-mix. • ECMAGROUT PU M 620 is then injected into the holes with a high-pressure pump capable of reaching pressures up to 200 bar. This forces the ECMAGROUT PU M 620 deep into the structure and allows penetration into the smallest cracks.
