The product is capable of incorporating large amounts of water that are multiples of its own mass, thereby forming a water proofing gel. The cure time of the product is determined by the amount of water added and the temperature. When it comes in contact with only small amounts of water (up to three times by voulme) the material reacts to closed cell foam while expanding. The cured material is flexible. Since water is a component of the cured product structure, the material can be affected by wet and dry cycles. The reacted material may shrink and swell as a result of the surrounding moisture content. The capability of the cured product to swell The capability of the cured product to swell and increase in volume due to water absorption is one of the important features that discriminate hydrophilic grouts from their hydrophobic counterparts of approved Make as per the manufacturers specification after complete sealing of the joint with high strength polymer modified repair mortar to avoid leakage of the injected material through it.Allowing the system material to get cured for its optimum technical properties or as manufacturer’s specifications Cutting of NRV packers and leveling of the surface by High strength polymer modified Mortar make or onsite mix, in required thickness to level the required surface complete all as specified and as directed.
