Tragumna Water Reservoir, Cork

Project Overview

Tragumna Water Reservoir is a crucial part to the water system which supplies water to houses and businesses around the local area in County Cork. Over time, the structure exhibited signs of weathering, structural wear, and required essential repairs to maintain its integrity and ensure compliance with potable water safety standards. Adrian Queally Ltd (AQL) was engaged to carry out a comprehensive refurbishment of the tower, addressing both external and internal deterioration while applying protective coatings to prolong the structure’s lifespan.

client objectives

-Ensure the longevity and structural integrity of the water reservoir. -Conduct essential concrete repairs to prevent further deterioration. -Apply protective coatings for weather resistance and long-term performance. -Stop any leaks within the tanks -Ensure compliance with potable water safety standards for internal surfaces. -Prevent future movement and cracking within tank

Scope of works

Surface Preparation Works – All external and internal surfaces were subjected to a high-pressure clean-down to remove contaminants, debris, and surface deterioration.Concrete Repairs to Structural Ring Beam- Structural elements suffering from wear and minor damage were mechanically removed and repaired using high-performance cementitious repair mortars.Crack Injection- Crack injection works took place to stop any leaks within the tank to stop any water ingress or egress.Internal Concrete Repairs and Surface Protective Coatings- All concrete elements that have been eroded or damaged due to erosion were rectified and DWI approved coatings were applied to protect the concrete in the future.External Joint Filling- All joints between panels were solid filled and a protective coating was applied over. All roof joints and cracks were address with joint sealing solutions to stop water ingress.Roof Surface Protection- The roof received a flexible, protective coating to resist environmental damage and extend the life of the concrete.Design & Installation of Steel Tension Bands- AQL designed and installed steel tension bands to help prevent any further movement or cracking within the tank.

Challenges

Access- This tank had poor access and was located within a farmer’s field. AQL therefore implemented the use of suitable all-terrain vehicles to transport materials, equipment and personnel to the tank efficiently and safely.Surface Contaminants & Deterioration: The presence of accumulated grime, biofilm, and pollutants on concrete surfaces necessitated a thorough high-pressure clean-down before coatings and repairs could be applied.Structural Weathering & Concrete Spalling: External concrete repairs were carried out using industry-approved repair mortars, ensuring structural elements regained their integrity.Potable Water Safety Compliance: The interior of the tower required the application of a fully compliant, potable water-approved surface waterproofing system to meet regulatory standards.

Results

Structural Longevity: The repairs and protective coatings significantly enhanced the lifespan of the Tragumna Water Reservoir, ensuring long-term durability.Weather Resistance: The joint sealing, concrete repairs, coatings and roof protection measures provided long-term resistance against harsh weather conditions, reducing maintenance requirements.Regulatory Compliance: The potable water-approved waterproofing system ensured the interior met the highest safety and hygiene standards for water storage.Improved Aesthetic & Functional Integrity: The reservoir now appears revitalised, with a clean, reinforced exterior that enhances its structural performance.

Conclusion

The successful completion of Tragumna Water Reservoir refurbishment highlights AQL’s expertise in structural water infrastructure repairs. Through meticulous planning, industry-leading materials, and specialist application techniques, AQL delivered a high-quality, long-lasting solution that ensures the water reservoir remains operational and compliant for years to come.
