BASEMENT WATERPROOFING DUBLIN | ST STEPHEN’S GREEN HOTEL PROJECT-CONSTRUCTION
A major basement construction project in Dublin city centre at St Stephen’s Green Hotel required a high-performance below-ground waterproofing and gas protection system to ensure long-term structural integrity.
Located in Dublin 2, one of the city’s busiest urban areas, the project combined modern construction techniques with the challenges of working in a dense, historic environment.
The development was delivered by Townlink, acting as both client and main contractor, with specialist waterproofing support from Baridek.
High-Performance Waterproofing System for Urban Basement Construction
To protect the structure below ground level, the project team installed PREPRUFE® 120S, a leading waterproof membrane system designed for:
Basement waterproofing
Gas protection
Long-term durability in challenging ground conditions
This solution ensured reliable protection for a habitable below-ground space, meeting both safety and regulatory requirements.
Project Challenges: High Water Table and City Centre Constraints
Delivering a basement waterproofing solution in Dublin city centre presented several key challenges:
Ground Conditions and Water Ingress Risk
A high water table required a robust waterproofing strategy
Protection against water ingress and gas penetration was essential
Budget and Performance Requirements
The solution needed to balance high performance with cost-effectiveness
Long-term durability was critical for the building’s intended use
Programme and Site Constraints
Tight construction timelines in a confined urban site
Limited access and the need for efficient installation methods
Minimising Disruption in a Busy Location
Works had to proceed with minimal disruption in a high-traffic Dublin city centre area
Maintaining public accessibility and operational continuity was essential
Why PREPRUFE® 120S Was Selected
The decision to use PREPRUFE® 120S waterproof membrane was influenced by strong collaboration between the project team and technical experts.
GCP’s established relationship with Townlink and Baridek, along with a proven track record in below-ground waterproofing systems, played a key role in product selection.
Key reasons for choosing PREPRUFE® 120S included:
Proven waterproofing and gas protection performance
Reliability in challenging basement environments
Suitability for tight urban construction sites
Cost-effective solution meeting project budget requirements
Fast and efficient installation process
Efficient Installation in a Confined Urban Environment
The ease and speed of installation of PREPRUFE® 120S supported the project’s demanding schedule.
Despite the constraints of a city centre construction site in Dublin, the membrane system allowed for:
Streamlined installation
Reduced programme delays
Greater flexibility on site
This ensured the project progressed efficiently while maintaining high construction standards.
Long-Term Protection for Basement Structures in Dublin
The completed waterproofing system delivered:
Reliable protection against water ingress
Effective gas barrier performance
Long-term durability for a habitable basement environment
The result is a high-performance, cost-effective waterproofing solution tailored to the demands of modern urban construction.
Positive Project Outcome and Contractor Feedback
The installation process ran smoothly, with the project team reporting strong satisfaction with both:
The ease of application
The overall performance of the waterproofing system
This reinforces PREPRUFE® 120S as a trusted choice for basement waterproofing projects in Ireland, particularly in complex city centre environments.
