The smart way to build foundations

With Durabase your conservatory or extension; you will experience a smoother process and quicker build time. Your bespoke, engineered steel base frame will sit on concrete pad foundations.After which, precision built side walls can be installed, that can be pre cut for running first fix electrics prior to insulation and your choice of internal finish. Externally the walls can be rendered, brick clad or timber clad to your specification.

Less waste
The only foundations required are a number of concrete pads placed at strategic points around the base. This means far less excavation work and waste material to dispose of compared to traditional methods of base construction.

Cost effective
No need for expensive relocating of manholes or drains. When work is required in tight spaces, traditional foundations would need deeper excavation. Durabase can work around existing structures.

25 guarantee
Durabase has been in business for 30 years, which means the product is tried and tested. Most builders offer a 1 year guarantee, we are so confident in the steel frame that we include a 25 year guarantee.
