Stack Replacement for Buildings in Use

Thanks to our Polypipe Advantage Service, it is now possible for decaying, unhealthy drainage stacks / soil stacks, often made from traditional materials to be taken out and replaced with new, modern plastic drainage stacks whilst residents remain living inside the building. This is particularly important for commercial buildings, schools, hospitals, high rise buildings, tower blocks and Local Authority Housing Associations as it is often difficult to re-home tenants whilst refurbishment work takes place.

Our highly-experienced technical design team can help your project so please contact us as soon as possible.
