Uses:
◇ For rapid and permanent reinstatement of discrete thick section areas in concrete carriageways, pavements, airport aprons, access ramps, floors, column and beams.
◇ Fosroc Patchroc 250 has a unique cement chemistry to rapidly reinstate thick sections of concrete without excessive heat generation and associated cracking. Particularly useful when interuption of traffic must be minimised.
◇ Patchroc 250 is suitable for repair methods 3.1, 3.2, 4.4, 7.1 and 7.2, as defined by BS EN 1504-3.

◇ May be left as a trafficable finish
◇ Suitable to be overlaid with compatible deck membranes and coatings when the moisture content is <6%, typically 3-4 hours after final setting.
◇ One component, pre-bagged to overcome site-batched variations requires only the site addition of clean water
◇ Does not normally require a primer to achieve high bond strengths
◇ Shrinkage compensation ensures no cracking
◇ Controlled heat of hydration minimises risk of thermal cracking, even in thick sections
◇ Contains no chloride admixtures
◇ Suitable for use with Cathodic Protection systems
◇ Shade can be varied with Renderoc Lightener/Darkener
