durabase cut through


Is the only conservatory base and modular building system that has JHAI approval certificate number 14021. This type approval supersedes the original BBA accreditation document which is over 12 pages long and really shows that the durabase is a tried and tested product. Durabase with this history is a real building solution not some temporary structure that will not be blown away the first time the British weather unleashes itself. The durabase is not new to the market and is now on its second round of warranties and in its 25th year of production so there are a lot of bases out there.

Background of the durabase

Being in its 25th year of manufacture In 2015 the decision was made that with the current changing market the durabase was to be moved forward to a fast track approval by Jhai. This was to become a complete building regulated approved offsite building system.

This system now includes prefabricated units made for buildings including the growth markets of orangeries, single storey brick extensions whilst still maintaining all the tried and tested conservatory base options and technology.

Put under rigorous testing for structural performance it's backed by a 25 year warranty can your builder match that?

In our experience, the average Durabase base takes 2 days to lay compared to 5 for a conventional base. With no skips required, the Durabase is truly an all-weather system- and the ideal way to get your conservatory build off on a firm footing.

The Durabase Difference

  • No compromise on stability, strength or load bearing capacity
  • Laying it requires little effort, expertise or specialist skills
  • There are no limitations on the size, shape or location of the base
  • It provides easy access for plumbing and electrical work as ducting and pipework is simply threaded through the walls
  • There's no need to move man-holes or drains as our system allows for them to stay in place
  • It comes with a 25 year manufacturer's guarantee.
