What Is A Durabase?

The Durabase System features a steel base that is bolted together on-site and fixed to the wall of your home using resin and anchor bolts. The base is made specifically for your build so it will be an exact fit. Durabase has so many positives compared to the old method of conservatory base building.
The Durabase once assembled will create a safe, strong and robust foundation for your building.

The only foundations needed from the Durabase feet are a number of concrete pads which will be concreted at specific points around the base.  This is so much less excavation work and hardly any waste material to dispose of compared to other methods of base construction. The Durabase System is also super fast to install. An average base and wall can be installed in less than two days.

Durabase Installation Process

The Durabase installation takes a fraction of the time of a traditional wet build, creates hardly any waste and can be installed to roof height within just two days. No mess, no fuss, just a thermally efficient building that you and your family can enjoy. Because no heavy excavation is required a Durabase conservatory base is perfect for homes with restricted access or limited parking. There is no need for skips, no need for builder teams and labourers, no heavy digging equipment.

Install concrete pads

Install Concrete Pads

The concrete pads are installed for the base to sit on, note the lack of mess and disruption. The pads are put in usually in a day, compared to older building methods this is much faster with minimal mess. The Durabase is a modern, cleaner and faster method of building bases for Conservatories, Orangeries and extensions. Alternatively, trench blocks can be used which is even faster than using concrete.

Assemble The Steel Frame

Once the foundation pads have been installed a membrane is laid down to prevent weeds from growing, the steel base is then simply bolted together. Once the frame is situated in position the feet are used to level the frame on the concrete pads, it is then all bolted securely to the wall using anchor bolts and resin.

Install The Brickwork Skirt

Now that the base is level and secured, the skirting is fitted to the steel base, this closes the gap between the floor and the damp course level, the skirts are buried below finished ground level ensuring nothing can get under the framework. Once the skirt is fitted the modular blocks are installed on the frame creating the walls.

Install The Roof Of Your Choice

Now that the walls are built, windows, doors and other fittings can be installed, then the roof is installed. The insides can now be installed, the flooring, insulation, electrics and plasterboarding.
