Temporary building installation

What are the best ground conditions for your structure?

Are you are looking to rapidly increase your space with a temporary building?  Two of the most important aspects to consider are firstly, where the building is to be located and secondly, how the structure will be fixed in place. We are temporary building experts, and this article will explain the best ground conditions for your structure.  Ultimately, there is very little ground preparation work required which makes our buildings a poplar choice…

Are foundations needed for a temporary building?

To answer the question simply, no, you will not need permanent foundations for a F&L temporary building. Good news as foundations and their excavations are costly, time consuming, disruptive and high risk. Why are foundations not required for our structures? They are engineered using high-grade aluminium frames complete with an integrated base plate system, which can be adapted to any ground condition. This is in contrast to steel framed buildings which often require complex foundations and additional ground preparation. Here is a quick reference table which shows the best anchorage method for the ground conditions on your site. Bespoke leg lengths are engineered to allow for variances in site levels.

Where can I install a temporary building?

We can complete a temporary building installation on practically any ground surface, including; concrete, undulating concrete, hardcore, tarmac, grass, uneven and contaminated ground. 

Our installation process is quick, non-invasive and cost-effective. Temporary buildings can be installed practically anywhere on your site in a matter of days, without the inconvenience and cost associated with traditional building projects. 

Temporary buildings have a small footprint, optimising the available space on your site. Your building can be free standing or integrated into any existing structure on your site. We can even provide a covered walkway or canopy to connect buildings. If your location is tight and you need to really maximise your space, a mezzanine floor can be added within our buildings, this works well for office space above storage.  If you have the land, we can develop a solution that fits your space.

What happens if I can’t penetrate the ground?

There is a solution! We often work on sensitive sites with contaminated ground where pinning or penetration is not an option. We will engineer a solution that uses the optimum amount of ballast to weight the structure down depending on its size and location. 

We recently used this approach for an industrial client. Our team engineered a counterweighted ballast anchoring solution for the structure. Four 2-tonne ballast blocks were placed on each custom-made leg of the building.

What base do I need for a temporary building?

The base for a temporary building can significantly impact the cost and overall sustainability of your project. The best ground surface or base will be dependent on how you intend to use your new structure. Most hard surfaces such as tarmac or concrete make ideal bases for temporary buildings. 

This means it is possible to use your existing surface for one of our structures without any additional work. Our team can also provide a solution to manage slopes so the ground surface does not need to be perfectly flat or level.
However, if the ground is very poor, or if your application requires specific ground considerations, a concrete slab can be used to create a suitable base. For example, we recently worked with a vehicle maintenance company to provide a temporary workshop which featured a maintenance pit in the bespoke concrete base.

How we help with pre-installation work

We provide unrivalled support for your temporary building project from start to completion and beyond. We have in-depth knowledge and years of experience when it comes to advising on the right approach. Your building can be free standing or integrated into any existing structure on your site. We can even provide a covered walkway or canopy to connect buildings. If your location is tight and you need to really maximise your space, a mezzanine floor can be added within our buildings, this works well for office space above storage.  If you have the land, we can develop a solution that fits your space. 

Design and engineering approach

As part of the design stage, our team conducts a thorough site survey, base stress test, and comprehensive ground level analysis. These surveys are crucial to ensuring that the sub-surface layers possess the necessary quality, thickness, and composition to effectively support the temporary structure. Additionally, our design process accommodates any variations in site topography. Our experienced engineers will deliver detailed technical drawings and, where required, precise CAD models to facilitate a seamless installation process.

Fixings and flashings

Once the base and location of the structure is agreed, there are a number of anchorage options to secure the building. Temporary structures are engineered to site-specific wind and weather loadings, ensuring stability even in exposed areas like seaports, docks, and coastal locations.  The location and ground conditions will have a bearing on the best anchorage solution and we can advise you on the best options.  To summarise the common fixing methodologies, these include:

Anchoring into concrete

This solution installs heavy duty threaded anchors into new or existing concrete surfaces. They are sealed in place using high-performance chemical resin to complete the bonding.

Installing on tarmac or hardcore

When installing a structure on compacted ground, we will secure the structure using multiple steel anchor pins. Typically these are 1.5m in length but the exact quantity and length is determined by our engineering department.


There are two options for ground flashing.  The first and most common is the L” style flashing, typically used to prevent pests, wind and a degree of water ingress. Secondly, we offer a “Z” style flashing which is chemically bonded to the existing base. In comparison to the “L” flashing, “Z” flashing offers enhanced preventative measures against water ingress. Finally, both styles can be colour and material matched to provide a seamless and professional atheistic for your structure.

Quality, durability and flexibility

Despite being termed ‘temporary,’ our buildings are designed to last over 20 years. They are solid and long-lasting, offering a quick solution for extra space.  Our structures comply with all UK Building Regulations and BS6339 quality standards .The numbers stack up well compared to the months or even years required for a permanent building.

Our temporary buildings can be purchased outright or rented on terms that suit your company. They are highly durable, making outright purchase a cost-effective option for long-term requirements. The building can be easily relocated if your business moves premises.  You will also own the asset and if you choose to move or no longer need the building there is a buoyant market for pre-owned temporary buildings.

Hiring a structure is a flexible way to increase capacity without significant upfront expenditure. Our flexible options and varying manufacturing lead times ensure we can meet your urgent needs with available stock.

In summary

Our temporary buildings offer a flexible and adaptable solution which can be designed to work on virtually any ground surface.  We have in house engineering expertise which means we can solve any challenge when it comes to installing a structure.  From contaminated land to tight spaces, we can find a solution. The installation speed is also impressive, we can generally install a standard size temporary building within a week.  This minimises disruption and downtime for your business.  Adding another check in the box as to why temporary buildings are so popular.  Our warehouse installation for IKEA demonstrates how fast and non-invasive the installation process is.
