DESCRIPTION

Technical Information

Patchroc 250 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 repair mortar. It is based on Portland cements, graded aggregates, and chemical additives providing a unique blend with good handling characteristics while minimising water demand. The low water requirement ensures rapid strength gain and long-term durability. Patchroc 250 may be applied in depths between 25 and 250mm in bays of up to 4m2 . Larger areas can be reinstated using a chequer-board “hit and miss” approach.

Where To Use

For rapid and permanent reinstatement of discrete thick section areas in concrete carriageways, pavements, airport aprons, access ramps, floors, columns 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 interruption 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. Patchroc 250 forms part of Fosroc’s Rapid Return to Service (RR2S) offer.

Advantages

  •  Rapid strength gain — will generally accept traffic in 2 hours at 20°C reducing downtime.
  •  Versatile - consistency can be adjusted to suit the application.
  •  High strength, abrasion and weather resistance, making it ideal for external works
  •  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 minimizes risk of thermal cracking, even in thick sections
  •  Contains no chloride admixtures
  •  Suitable for use with Cathodic Protection systems
