Because we’ve been making waterproof treatments, here in the United Kingdom, in our own factory since 1937. The products in the current Grangers range pull on 77 years of research and development to ensure the ultimate performance possible.
Grangers started in 1937, with its first business coming from the MOD who needed a waterproof treatment to maintain its canvas tents. The company steadily grew and added various other products into the range covering every market from camping to construction. The one common link – offering the best possible levels of water repellency whether it was canvas or brick.
In 1977 the company was bought by its current owner. 10 years later the original factory in Watford was closed and both the factory and laboratory were moved north to its current location in Alfretron, Derbyshire.
We’re proud to say that all our chemical products are designed and manufactured in the UK.
At Granger’s we believe that independent accreditation is the only true way to demonstrate the performance of our products. For independent testing we use SATRA, a leading authority on testing for footwear, leather goods and apparel. For more information about SATRA, please visit: www.satra.co.uk. To view the results of these tests and other previous testing by Leeds University/Trail please visit our download area.
In 2006 Granger's was also awarded certification under the ISO 14001 Environmental Management standard, independent confirmation that Granger's products and processes conform to the highest environmental principles.
