Specialist underpinning in Brighton for residential and commercial properties, providing reliable foundation strengthening solutions for existing buildings.
Dedicated to excellence, we are trusted providers of accredited services throughout the local area.





Alunia Construction provides professional underpinning in Brighton, East Sussex and the surrounding areas. We work on residential and commercial properties where existing foundations require additional support due to movement, increased structural loads or changing ground conditions.
Underpinning strengthens and stabilises the foundation of an existing building. It can provide a long-term solution where there are signs of subsidence or instability and may also be required when extensions or structural alterations place additional loads on the original foundation.
We provide a range of underpinning solutions for properties in Brighton, tailored to the requirements of the building and site. Our services include:
For groundworks, formwork and RC foundations in Eastbourne, Hastings and the surrounding areas, call 01323 488 558 or 07446 088 695.

Our experience extends beyond traditional underpinning. Alunia Construction specialises in reinforced concrete, foundations and structural groundworks, giving our team the technical knowledge required for more complex foundation projects.
Our wider construction services include formwork, steel fixing, reinforced concrete foundations, piled foundations, concrete basements and retaining walls. This allows us to provide specialist support across different stages of a structural groundwork project rather than treating underpinning in isolation.
For projects requiring beam and base or reinforced underpinning, our experience in formwork, reinforcement and concrete construction provides a strong foundation for delivering accurate, durable work.
Set out below are examples of some of the diverse projects we have successfully completed for a number of our valued clients.

What is underpinning?
Underpinning is a method of strengthening and stabilising the foundations of an existing building. It may be required where foundations have moved or become unstable, or where structural alterations will place additional loads on them.
What types of underpinning do you provide in Brighton?
Our underpinning services include traditional mass pour underpinning, reinforced underpinning, beam and base underpinning and mini piled underpinning systems. The appropriate method will depend on the existing foundations, structure and site conditions.
When might a property need underpinning?
Underpinning may be required where an existing building is experiencing foundation movement or instability. It can also be necessary when extensions or structural alterations increase the load placed on existing foundations.
Do you provide reinforced concrete and foundation services?
Yes. Alunia Construction specialises in reinforced concrete, foundations and structural groundworks. Our services also include formwork, steel fixing, retaining walls, concrete basements and piling.
