M&L for PU Injection Grouting : Clean the surface and remove any dust, unsound or contaminated material, plaster, oil, paint, grease, corrosion deposits or algae. The surface should preferably be prepared using high pressure water jetting or light abrasive blasting, followed by thorough washing to remove dust and remaining particles. Dirt alone may be removed with wire brushes or similar mechanical means. Oil and grease deposits should be removed by steam cleaning, detergent scrubbing or the use of a proprietary degreaser. The effectiveness of decontamination should be assessed by a pull-off test. Blow the cracks and treated surface with oil free air to ensure complete removal of all dust and loose particles. Ensure that the surfaces are blown dry. In the presence of running water the flow must be stopped using Nitofill WS60 which produces a rapid setting waterstopping foam. When the water is stopped the cracks are reinjected with Nitofill UR63. All cracks must be sealed and injection packers or nipples located in place before Nitofill UR63 is injected. Once grouting operation is completed remove the packers and make good any holes or voids with Nitomortar FC and allow to cure. The Nitomortar FC can be ground off or softened with a blow lamp and peeled off complete all as specified and directed.
