Fosroc’s new solution for fast return to service for Highway repairs
Designed for highway use, Fosroc have launched a new solution providing customers with considerable savings in both time and cost. Patchroc 250 joins a suite of new products designed to provide fast, effective and durable repairs to UK highways.
Working closely with contractors on major road projects, Fosroc recognised the requirement for a product which could provide rapid and permanent reinstatement of localised thick section patches in concrete carriageways. After more than 30 years Fosroc’s Patchroc GP continues to enjoy an established position in the market as a patch repair mortar, but the new Patchroc 250 product developed by the technical team at Tamworth, features improved characteristics providing customers with considerable savings in both time and cost.
Trafficable finish within 2 hours
With its high strength, abrasion and weather resistance Patchroc 250 is ideal for external works and can be left as a trafficable finish for use within 2 hours. Alternatively it can be overlaid with deck membranes and coatings. Whereas traditional repair materials require 7 – 28 days to adequately dry before they can be over-coated, Patchroc 250 achieves a surface moisture content of <6% in 4 hours, potentially offering drastic time and cost savings if being used in combination with a deck waterproofing system such as Fosroc’s Matacryl.
Patchroc 250’s unique cement chemistry, providing rapid setting and rapid strength gain, but low heat generation, ensures no thermal cracking at high thickness. It also has low hydration shrinkage further reducing the risk of cracking. The thicker section means that most repair depths can be patched in a single application.
Easy to use
Importantly Patchroc 250 also meets the requirement of being easy to apply: it is supplied as a one component, pre-bagged material to overcome site batched variations and requires only the site addition of clean water. It requires the same HSE considerations as standard concrete. It is supplied in both 25 kg bags and 500kg sacks and can be used without a primer for most applications, yet still achieves an excellent bond to the concrete substrate.
