WATER-RESERVOIR WATERPROOFING IN GARRAF

Garraf Reservoir

  • Civil works
  • Water

Commissioned by Aigües Ter-Llobregat, we carried out the complete refurbishment of the internal waterproofing of an operational water reservoir. The project required detailed planning to minimise downtime and ensure immediate commissioning once the works were completed.

The intervention improved the watertightness, safety and durability of the facility by applying state-of-the-art waterproofing technologies and sustainability criteria that ensure minimal maintenance and greater efficiency in water-cycle management. As the reservoir remained in service, the main challenge was to guarantee structural safety and sanitary water quality throughout all phases of execution.

We have brought to fruition

Greater durability, safety and sustainability

  • Deteriorated elements were replaced and a next-generation waterproofing system with high performance and chemical resistance was applied, extending the service life of the facility and reducing future maintenance needs. This contributes to more efficient and sustainable water-cycle management.
  • Hybrid polyurea/polyurethane waterproofing products were used, offering excellent adhesion and flexibility to accommodate structural movements. Application was carried out using state-of-the-art hot-spray systems, ensuring homogeneous and fast execution.
  • At management level, a digital system for material traceability and watertightness testing was implemented, ensuring full verification prior to commissioning. The final result was positively assessed by Aigües Ter-Llobregat (ATL) for its technical quality, adherence to deadlines and minimal impact on water-supply services.
