Property Typical result Compressive strength at 23°C 43 Fosroc® Paveroc Floor / pavement large area, repair mortar (15-50 mm depth) Uses For the reinstatement of large areas of concrete pavements and floors to avoid the total replacement of bays. The rapid strength gain of Paveroc will ensure that downtime is significantly reduced. The product is alkaline in nature and will protect embedded steel reinforcement. It may be used internally and externally. For emergency patching of small areas of concrete pavements and floors, the use of Patchroc GP is recommended. Advantages „ Rapid strength gain - will generally accept pedestrian traffic at 16 hours „ High strength, abrasion and weather resistance „ Single component product eliminates site batching and requires only the site addition of clean water „ Excellent bond to the concrete substrate „ Shrinkage compensated „ Contains no chloride admixtures Description Paveroc is supplied as a ready to use blend of dry powders which requires only the site addition of clean water to produce a highly consistent, high strength repair mortar for large areas of concrete pavements and floors. The material is based on a blend of cements, graded aggregates, special fillers and chemical additives to provide a mortar with good handling characteristics, while minimising water demand. Paveroc exhibits excellent thermal compatibility with concrete and good water repellent properties. The low water requirement ensures fast strength gain and long- term durability. Technical Support Parchem offers a technical support service to specifiers, end-users and contractors, as well as on-site technical assistance. Design Criteria Paveroc is designed for horizontal use. It may be applied up to a maximum thickness of 50 mm. Thicker sections can be built up in layers. The material should not be applied at less than 15 mm thickness. Individual bay sizes should not exceed 18 m2 @ 50 mm thickness and 5 m2 @ 15 mm thickness. Consult your local Parchem sales office for further information.

Due consideration must always be given to existing joint details and these must be followed through the Paveroc repair; live cracks should be treated by an approved method. For further information, contact your local Parchem sales office. Preparation Saw cut or cut back the extremities of the repair locations to a depth of at least 10 mm to avoid feather-edging and to provide a square edge. Break out the complete repair area to a minimum depth of 15 mm up to the sawn edge. Clean the surface and remove any dust, unsound or contaminated material, plaster, oil, paint, grease, corrosion deposits or algae. Where breaking out is not required, roughen the surface and remove any laitance by light scabbling, grit-blasting, scabbling or by needle-gun to form a good key. Oil and grease deposits should be removed by steam cleaning, detergent scrubbing or the use of a proprietary degreaser. The effectiveness of decontamination should then be assessed by a pull-off test. Expose fully any corroded steel in the repair area and remove all loose scale and corrosion deposits. Steel should be cleaned to a bright condition paying particular attention to the back of exposed steel bars. Grit-blasting is recommended for this process. Where corrosion has occurred due to the presence of chlorides, the steel should be high pressure washed with December 2009
