Interlocking concrete blocks can be used for a wide range of temporary applications*, including:

• • Temporary storage bays: This can be used on construction sites or recycling centres and more. It creates a specific safe space for storage. 

• Traffic barriers: Provides alternative traffic flow during roadworks or other site works near roads. 

• • Security barriers: Allows for orderly cues, and helps to prevent people from illegally entering an area.

• Retaining walls: used to create levels and optimise space within gardens and green spaces. Can organise hilly spaces.

• Flood defences: Can be used to help divert water that would otherwise flood a specific area.

*Please note that the types of structures that interlocking concrete blocks can vary depending on the provider. It is best to speak to a variety of providers and confirm if their blocks can facilitate the building of the temporary structure you need. 

Can I use interlocking concrete blocks to build temporary structures?

Yes. It is entirely possible, and in most cases, the better option to use interlocking concrete blocks to create temporary structures. With interlocking concrete blocks, like those available from PPC Concrete Products, provide a list of benefits for temporary structures. Here’s the most important benefits:

• Easy assembly & disassembly: Interlocking concrete blocks need handling with heavy lifting equipment, they do not need mortar to create a lasting connection. They connect via studs and recesses that allow for the lifting equipment to connect the blocks, and eventually separate the blocks once the temporary structure has served its purpose. 

• Heavyweight and durable: Concrete blocks are heavy by nature, and has a durable constitution. This makes them ideal for temporary structures that are in challenging environments. 

• Flexibility and Reconfigurability: Interlocking blocks can be easily rearranged to create various configurations, adapting to changing site requirements. This flexibility is invaluable for temporary structures that may need to be modified or moved frequently.
    

• Stacking capability: The stacking capability of interlocking concrete blocks gives them greater levels of application for various types of temporary structures.

• Cost-Effectiveness: The speed of installation and the elimination of mortar contribute to cost savings. Furthermore, the reusability of the blocks further enhances their cost-effectiveness for multiple temporary projects.

• Security: The sheer weight of these blocks creates very effective security barriers, preventing vehicle access, and unauthorised personnel access.

How long can I keep a temporary structure up with interlocking concrete blocks?

Interlocking concrete blocks can last for years depending on their environment and maintenance. However, keeping a temporary structure up isn’t really about the blocks themselves, it’s about planning permission. 

Here’s a general overview based on UK guidelines:

Planning permission:

• In the UK, a “temporary structure” has specific legal definitions. Generally, if a structure is intended to be in place for more than 28 days in a calendar year, you’ll likely need planning permission.   

• There are also size limitations. If the structure exceeds 100 square meters, planning permission is typically required, regardless of the duration.   
• Certain activities, like markets or racing events, have even stricter time limits (e.g., 14 days).   

Local Regulations:

• Local planning authorities can have their own specific rules and interpretations. It’s crucial to check with your local council for precise regulations in your area.

“Temporary” vs. “Permanent”:

• Even if a structure is made of movable blocks, if its intended use becomes long-term, it can be reclassified as a permanent structure, triggering further planning requirements.

Practical Considerations:

• While the concrete blocks themselves are very durable, the ground they sit on can shift over time. If you plan on having a structure up for a long period of time, even if considered temporary, you will need to consider the ground that the blocks are sitting on.

General guidance for temporary structures:

For short-term needs (less than 28 days), you might be able to erect a structure without planning permission, provided it meets size restrictions. For longer durations, it’s essential to obtain planning permission to avoid legal issues.

Always consult your local council for definitive guidance on planning permission requirements and keep detailed records of the structure’s intended purpose and duration.
