Foundations & Underpinning
Expert Foundations for Lasting Structural Stability
Strong and stable foundations are the backbone of any successful construction project. Without a properly installed foundation, structures can suffer from uneven settling, cracks, or even complete failure over time. Fry Site Services specialises in delivering high-quality foundation and underpinning solutions that provide lasting stability for residential, commercial, and industrial buildings. Our team has extensive experience in preparing sites, installing robust foundations, and reinforcing existing structures to ensure they can withstand varying ground conditions and environmental factors.
Whether you are constructing a new build, extending an existing property, or addressing structural weaknesses, we tailor our approach to meet the specific requirements of the project. From shallow foundations for light structures to deep foundations capable of supporting multi-storey buildings, we assess each site carefully and select the best method to ensure long-term performance.
Strengthening Buildings with Reliable Foundations & Underpinning
Over time, buildings can experience subsidence, shifting, or foundation deterioration due to factors such as soil movement, water infiltration, or insufficient initial construction. When this occurs, underpinning is required to strengthen and stabilise the existing foundations, preventing further damage and restoring the structural integrity of the building. Fry Site Services provides expert underpinning solutions, using proven methods that are tailored to the unique conditions of each site.
Our team offers traditional mass concrete underpinning, which involves extending the foundation depth to more stable ground, as well as more advanced techniques such as mini-piling and resin injection for projects where space is limited or where soil conditions require a specialised approach. We conduct thorough site assessments to determine the most effective method for reinforcing the foundation while minimising disruption to the surrounding property.

Frequently Asked Questions
What is the difference between foundations and underpinning?
Foundations are the structural base of a building, designed to evenly distribute weight and provide long-term stability. They are installed during the initial construction phase to ensure the structure remains secure. Underpinning, on the other hand, is used to strengthen or repair existing foundations that have become unstable due to subsidence, soil movement, or structural alterations. It involves reinforcing or extending the foundation depth to reach more stable ground, preventing further movement and ensuring the building remains safe.
How do I know if my building needs underpinning?
Signs that a building may need underpinning include cracks in walls or floors, doors and windows becoming misaligned, sloping or uneven floors, and visible gaps between walls and ceilings. These issues often indicate subsidence or foundation movement, which can weaken the structural integrity of a property. If you notice any of these warning signs, a professional assessment is essential. Our team conducts thorough site inspections to determine the extent of the issue and recommend the most effective underpinning solution.
What types of underpinning do you offer?
We provide several underpinning methods, each suited to different ground conditions and structural requirements. Mass concrete underpinning is the most traditional method, involving the excavation and extension of foundation depths to more stable ground. Mini-piling underpinning is ideal for restricted access sites and weak soil conditions, using deep-driven piles to redistribute weight. Resin injection underpinning is a non-invasive technique that strengthens the ground beneath the foundation by injecting expanding resin, stabilising the structure with minimal disruption. Our team assesses each site individually to determine the best underpinning method for long-term stability.
How long does it take to install new foundations or complete underpinning work?
The timeline for foundation installation or underpinning depends on factors such as site conditions, project size, and the method used. New foundations for residential or commercial buildings typically take several weeks, depending on complexity and ground conditions. Underpinning projects can range from a few days to several weeks, depending on the extent of subsidence and the chosen underpinning technique. We work efficiently to minimise disruption while ensuring the structural integrity of the building is fully restored.
