Structural Repair of Period Property Following Ground Movement
A semi-detached period property in Dublin 6, designated as a protected structure, experienced significant structural movement arising from a leaking water main.
The damage affected both the main building and a rear annex, requiring a carefully coordinated approach combining structural stabilisation with conservation-led repair works.
The project was carried out under an insurance claim and involved extensive intervention to both structure and finishes.
The Issue
- Structural cracking to walls and internal elements
- Sloping and uneven floors at ground and upper levels
- Movement affecting both the main structure and annex
- Water-related ground softening due to leaking services
The nature of the building introduced additional complexity due to its protected status and historic fabric.
Engineering & Conservation Approach
A combined structural and conservation strategy was developed, including:
- Installation of a stabilising foundation system (piled raft) to support existing walls
- Underpinning works to the rear annex
- Temporary works to facilitate safe structural intervention
- Careful removal and reinstatement of internal floors
All works were designed to:
- Stabilise the structure
- Retain as much original fabric as practicable
- Comply with conservation requirements
Planning & Conservation Coordination
The project required close coordination with the local authority Conservation Department.
- Proposals were developed and agreed in consultation with Dublin City Council
- All interventions were designed in accordance with conservation best practice and planning requirements
- The works sought to:
- Prevent further structural deterioration
- Secure the long-term use of the building
- Retain and protect original fabric and architectural features
A key principle of the design approach was the use of appropriate and, where feasible, reversible interventions, ensuring that the character and integrity of the protected structure were maintained.
Conservation-Led Repairs
Significant emphasis was placed on preserving and reinstating original features:
- Use of lime-based plaster and finishes throughout
- Retention and reuse of salvageable elements including:
- Timber flooring
- Skirtings
- Joinery details
- Repair and reinstatement of ceilings, including structural support where required
- Careful integration of upgraded building elements within the historic fabric
Works were carried out by a contractor experienced in conservation and heritage properties.
Reinstatement & Upgrades
Following stabilisation:
- Floors were re-levelled and reconstructed with improved performance
- Insulated floor construction introduced where appropriate
- Internal layouts and elements were carefully adjusted to suit modern use while respecting the original structure
Outcome
- Structural movement was addressed through foundation stabilisation and repair works
- The property was restored in a manner consistent with its protected status
- Original features were retained and enhanced where possible
- The client successfully returned to occupation following completion
