When most people think about foundations, they picture trenches, concrete lorries and weeks of disruption. That's understandable: that's been the standard approach for decades. However, nowadays, it isn't the only option.
At Techno Metal Post UK , we design, manufacture and install helical pile foundations, also known as screw piles or ground screws. These offer a fast, 'clean' and convenient alternative to traditional concrete, suitable for a wide range of residential and commercial projects across the UK.
While decking and small extensions are common applications, many people are surprised by just how versatile helical pile foundations can be.
Here are five projects you might not immediately associate with screw batteries, and why they work so well.
1. Garden Rooms and Home Offices
The rise in home working has led to a surge in garden rooms and offices. Many homeowners assume a concrete slab is the only way to support these structures. In reality, screw pile foundations are often a better fit.
At Techno Metal Post UK, we regularly support timber-framed garden rooms, insulated studios and modular office pods using our helical batteries. The installation process is typically completed in a single day, with no excavation and no need for curing time. That means builders can begin construction almost immediately.
This is particularly useful in gardens where access is limited. Our proprietary, high-precision equipment allows us to work in tight spaces without heavy machinery tearing up lawns or paving.
From an engineering perspective, we provide the necessary load calculations and ensure compliance with UK building regulations.
2. Modular and Prefabricated Buildings
These types of buildings are appearing more often across the UK. Schools, healthcare units, retail spaces and site offices are increasingly built off-site and assembled quickly on location. The foundations need to match that speed.
Helical batteries are ideal for modular buildings because they can be installed quickly and with predictable load-bearing performance in almost any condition of soil. There are no delays caused by heavy rainfall turning sites into mud.
At Techno Metal Post UK, we work closely with modular building suppliers and contractors to provide tailored foundation designs. Because we manufacture our own batteries and operate through a network of trained and certified installers across the UK, we can coordinate efficiently with project timelines.
For temporary modular structures, screw piles also offer a major advantage. They can be removed at the end of the building's life with far less environmental impact than breaking out concrete. This makes them a strong option for projects where sustainability and reversibility matter.
3. Underpinning and Structural Remediation
When a building suffers from subsidence or foundation failure, underpinning is often required. Traditional underpinning methods can be invasive, time-consuming and disruptive to occupants.
Helical batteries provide a controlled and efficient solution for underpinning existing structures. Because they are mechanically screwed into the ground to reach stable load-bearing strata, they can transfer loads away from weak or shifting soil.
At Techno Metal Post UK, we design and install screw pile underpinning systems tailored to the specific building and soil conditions. Our engineering services are a key part of this process. We assess loads, provide calculations, and ensure full building code compliance.
Installation can often be carried out with limited excavation, which reduces disruption to the property and surrounding area. This is especially valuable in urban settings where access is restricted and neighboring properties are closed by.
For property owners and developers, the combination of speed, precision and reduced mess makes helical pile underpinning a practical alternative to more traditional approaches.
4. Solar Panels and Renewable Energy Installations
As the UK continues to invest in renewable energy, ground-mounted solar arrays are becoming more common on commercial sites, farms and even large residential plots.
Concrete bases for solar frames can be expensive and labor-intensive, especially over large areas. They can also permanently alter the ground. Screw batteries offer a cleaner and more adaptable solution.
Helical batteries can be installed quickly across a site, even in challenging conditions. Because there is no need for extensive excavation, the surrounding land remains largely undisturbed. This is particularly important on agricultural land where the health of the soil matters.
5. Boardwalks, Decking and Waterside Structures
Boardwalks, raised pathways and waterside decks often present foundation challenges. Soil conditions may be soft, saturated or uneven. Traditional concrete foundations can be difficult and costly to install in these environments.
Helical batteries perform well in a wide range of ground conditions, including clay, sand and areas with high moisture content. Because they are screwed into the ground rather than cast in place, installation can be cleaner and more controlled.
We have supported projects ranging from residential decking to larger commercial boardwalk structures. Our system allows for precise alignment and height adjustment, which is critical when building over uneven terrain or near water.
In environmentally sensitive areas, minimizing disturbances is essential. Our no-excavation approach helps preserve surrounding landscapes while still delivering strong, durable support.
