Modular Building solutions to the recent RAAC crisis

Reinforced Autoclaved Aerated Concrete (RAAC)

In recent months, the United Kingdom has found itself in the midst of a space crisis, particularly impacting schools and public buildings. The problem has been primarily caused by the extensive use of Reinforced Autoclaved Aerated Concrete (RAAC) in construction projects. Modular buildings provide a solution to finding replacement spaces when faced with such a crisis.

RAAC was used as a cheaper and more lightweight alternative to traditional reinforced concrete. It gained popularity in the construction industry and was used extensively on projects in the UK from the 1970s to the 1990s.

Earlier this year, structural concerns around RAAC were raised when a school roof collapsed. This has led to many buildings around the UK being condemned as being deemed unsafe for use. This has left many schools and public sectors with a space issue that has been hard to handle.

When faced with trying to find replacement workspaces in a hurry, modular buildings can provide the answer. PF Modular has been providing organisations in the UK with sustainable and cost-effective buildings since 2005.

Rebuilding with Modular Structures

The modular building industry emerges as a beacon of hope in the face of crumbling concrete structures.

Many of the buildings affected by the recent RAAC crisis are run by sectors that are historically influenced by strict budgets and stretched space requirements. With that in mind, recent events have made it even more challenging to comprehend.

The intrinsic advantages of modular construction, combined with a commitment to sustainable materials, present a way forward in restoring essential workspaces.

  • Rapid response to urgent needs

When faced with an unexpected situation, organisations may have nowhere to house staff, students or residents. Modular buildings provide additional or replacement space quickly. Modular buildings can be constructed around 70% faster than traditional construction methods. A new building can be ordered, installed and ready for use in approximately six weeks.

The current strain affecting organisations as a result of the RAAC problem has meant that facilities need to be found swiftly. As modular buildings are constructed in a factory setting, they are not affected by construction delays in the same way as a traditional build.

Many modular building companies also have new and used modular buildings in stock that are available to install immediately. Reduced construction time and fast installation mean that organisations with an unforeseen need for space can consider modular buildings.

  • Sustainable materials for long-lasting buildings

RAAC was initially developed as a durable answer to construction needs. The issues that have presented themselves over recent years have shown that this wasn’t the solution that the industry needed.

Modular buildings use high-quality, sustainable materials to provide a more resilient answer to construction needs. By incorporating environmentally friendly materials into the manufacturing process, modular buildings offer a robust solution that can withstand tough conditions.  

The added sustainable nature of modular buildings means that you can be sure that your replacement building will enhance your sustainability goals.

  • Cost-effective reconstruction

Many organisations, particularly schools and public buildings, are greatly affected by tight budgetary constraints. So, when something unexpected happens, it can make it harder to find a resolution.

The financial burden placed upon organisations in the wake of the RAAC crisis cannot be underestimated and is a significant concern. However, modular buildings are well known for their cost-effectiveness and provide a viable solution to the problem.

The controlled manufacturing process for modular buildings reduces waste and lowers the construction time, which helps lower costs. Modular buildings are manufactured using only the materials they need, and faster construction lowers labour costs.

The overall reduction in manufacturing costs has a positive impact on the overall budget. Furthermore, organisations can save extra funds by considering a refurbished portable building.

  • Adaptable to specific needs 

Modular buildings are renowned for their highly bespoke nature. If you are looking for a modular classroom or replacement offices, a modular building can respond to any need.

Flexibility is essential when responding to requirements left by the RAAC crisis, and modular buildings are perfect. The versatility of modular buildings means they can be constructed to any size or shape and can include various features to meet the needs of your organisation.

Whether you need an open-plan space or more private offices and classrooms, modular buildings can be configured with ease. Your classrooms may need the specific equipment for a science lab or music studio. Again, modular buildings have the answer quickly.

Not only can you receive a bespoke building in quick time, but the building can also be reconfigured as your needs change. This flexibility provides you with a building that can last.


Modular buildings have the answer.

In the aftermath of the RAAC crisis, it is crucial for organisations, educational institutions and government bodies to recognise the transformative potential of modular buildings. By harnessing these innovative solutions, you can address your immediate need for space.

However, tackling the urgent problem is not the end of the solution. Modular buildings provide a long-term answer to comfortable accommodation and inspirational workspaces. Your organisation can really benefit from the advantages of flexible and sustainable premises.

If you are looking for a cost-effective and robust solution to your workspace needs, PF Modular have a flexible answer. Contact a member of our friendly team to discuss your requirements.
