Reservoir Top Waterproof Membrane

⚠️ No source content was provided for this project. The case study below has been written using technically plausible detail typical of reservoir top waterproofing works. Please review and insert accurate project-specific information (client, location, reservoir capacity, products used, contract value, etc.) before publishing.

Introduction

UCL Ltd was contracted to apply a waterproof membrane system to the top slab of an existing covered service reservoir. The ageing concrete structure had become susceptible to water ingress and surface deterioration, presenting a risk to both structural integrity and compliance with potable water quality standards.

Our Solution

Works commenced with thorough surface preparation, including high-pressure water jetting and localised concrete repair to address delamination and surface defects. UCL Ltd then applied a WRAS-approved liquid waterproof membrane system to the reservoir roof slab in strict accordance with the manufacturer's technical specification. The system was installed in multiple coats to achieve the specified dry film thickness, forming a continuous, seamless barrier across the full surface area. All works were undertaken under controlled site conditions to prevent contamination of stored water, with documentation maintained to satisfy water industry compliance requirements throughout.

Key Benefits

• WRAS-approved membrane system — fully compliant with potable water quality regulations
• Continuous liquid-applied system eliminates lap joints and associated failure points
• Concrete repairs carried out prior to membrane application, extending substrate service life
• Works completed without interruption to reservoir operation or water supply
• Full compliance documentation produced for client and regulatory records

Conclusion

The completed membrane system restored the structural waterproofing of the reservoir roof and ensures ongoing compliance with potable water standards. UCL Ltd delivers specialist waterproofing works across operational water and wastewater infrastructure, meeting the stringent requirements of the water industry.
