Quadriga provides conservation, restoration, and preservation services for historic buildings using traditional building crafts and modern technology. They have restored features of several notable historic buildings in the UK such as Afflecks Palace in Manchester, the Royal Liver Building in Liverpool, and Victoria Station in Manchester. Their work involves concrete repair, terracotta restoration, resin bonding of architectural elements, and restoration of decorative interiors such as mosaic floors and plaster ceilings.

1. Quadriga Project Profiles
By Lindsay Law
In recent years we have experienced an awakening in a need for the conservation
of our heritage. A specialist approach is needed which combines a thorough
understanding of traditional building crafts and the latest advances in technology.
Quadrigas’ work illustrates how traditional, as well as contemporary repair solutions,
can be used in conservation, restoration and preservation.

setting concrete. Kemper system applied to cupola’s.

6. Middlesbrough College
This once derelict bonded warehouse façade has been structurally repaired by Quadriga
using Helical bar reinforcement and brickwork restoration. A great example of bringing
old and new architectural styles together. All 1800 original bricks
of this façade where re-used.

7. The Pier Head Building, Cardiff
The Pier Head Building is a very grand example of Victorian architecture.
The terracotta with ferrous dowels resulted in corrosion/expansion along
with cracking/spalling of the detail to this 1802 building.
Resin bonding and pinning proved to be a very useful repair technique for
this historic building project.

8. Resin Bonding & Pinning
Gargoyles where painstakingly put back together like a jigsaw using steel pins and resin
bonding. The final piece was resin bonded together and then fixed to the steel armature
Projecting from the façade.
A fully restored gargoyle drainage outlet
and duck head ornate relief fully restored

9. Relief Panel Restored
Corroding steelwork behind this relief panel to the Pier Head Building had caused
structural fracturing of the terracotta which had to be removed, steel blasted
and a bitumen based protective coat applied.
This was followed by the installation of new terracotta.

10. Terracotta Restoration
New Bond Street
Working from old photographs and what detail remained of the original façade,
we were able to recreate what had been at No27 previously using our in house
terracotta designer.

11. Terracotta Restoration
New Bond Street, C1930
We produced full detail design shop drawings for the manufacture and installation
of the new frontage

12. 27 New Bond Street, London
Some original detail did get uncovered which gave us the opportunity
to take accurate presses of the relief work

13. 27 New Bond Street, London
The finished façade complete with brass window frames has now recreated
what is a beacon of historic ceramic architecture back on this most prestigious of London streets.
It is a testament to the skills and craftsmanship still available today.
