Since its inception in 1989, Flexseal has been at the heart of the civils and drainage sectors, playing a vital part in shaping the way contractors repair and refurbish drainage and sewer pipelines.

With a track record stretching back over 30 years, we highlight our strong strategic relationships with UK builders’ merchants as a key reason for our success. As a longstanding member of the Builders Merchants Federation (BMF), Flexseal has always been committed to supporting its builders merchant partners, working closely with them to shift with the changing demands of the end-users.

Over the past 30 years, we’ve aligned our business with our merchant partners, making Flexseal easy to deal with and providing helpful tools and service offerings to ensure our resellers are completely equipped to maximise their opportunities.

When a merchant becomes a Flexseal stockist, they’re not on their own. We have teams dedicated to supporting the growth of their business which is backed up by joint a commercial plan.

“Our ethos at Flexseal is to always look for ways that we can add value to the businesses we work with.”
Lee Pashley, Managing Director
