We have always been passionate about exploring advances in highways technology and how we can implement these improved practices to benefit our loyal customers. With this in mind, we have developed innovative and premium packaging for our world renowned Instant Road Repair 6mm and 10mm grades.

Made from foil and complete with an integrated valve to draw out excess air, Instant Road Repair’s new packaging is completely waterproof and keeps asphalt as fresh as the day it was manufactured. This state-of-the-art packaging also provides a barrier against external moisture and air penetration preventing the product from deteriorating, resulting in an extremely pliable product which pours easily from the bag and boasts improved mobility during application – even in the winter months!

We have been supplying trusted and proven products to national highways agencies, contractors, local authorities and commercial organisations in the UK and around the world for over 40 years.

Every one of our clients benefits from our personal, efficient and award-winning customer service that includes free text updates, email confirmation, Product Planner App and dedicated field and office based customer support.
