Solving Roof Deck Leaks at a Hospital in Quezon City: A Case Study

Project Overview

A hospital in Quezon City, Philippines, faced a critical challenge with persistent leaks in its concrete roof deck. Uneven slopes and a deteriorated bitumen membrane beneath the concrete topping were identified as the root causes. To resolve these issues, EVERDRY Waterproofing was engaged to deliver a durable and efficient solution with minimal disruption to hospital operations.

The project commenced in August and was successfully completed within the agreed timeframe by November, despite challenging weather conditions during the typhoon season. The affected roof deck spanned a total surface area of 1,500.00 square meters.

Project Requirements

The hospital outlined specific priorities for the waterproofing work:

• Effective Waterproofing: Ensure a long-term solution that eliminates leaks and prevents future water ingress.

• Minimal Disruption: Use methods and materials that minimize noise and allow the hospital to maintain operations without interruption.

• Timely Completion: Complete the project within the stipulated schedule despite weather and operational constraints.

  
  

EVERDRY's Solution

To meet the hospital's requirements, EVERDRY Waterproofing designed and executed a tailored plan:

1. Surface Preparation:The team removed the existing concrete topping and delaminated bitumen membrane, exposing the underlying surface. This was followed by minimal cleaning and structural repairs, including V-cutting and epoxy injection, to treat cracks and leaks effectively.

2. Installation of TPO Membrane:EVERDRY selected Thermoplastic Polyolefin (TPO) as the waterproofing material. This choice was based on its durability, flexibility, and ability to reduce noise—a critical factor for a hospital environment. The installation included turn-ups on parapet walls and detailed sealing to ensure complete protection.

3. Flood Testing:A rigorous 48-hour flood test was conducted post-installation to confirm the integrity of the waterproofing system.

4. Weather Challenges and Adaptability:Despite several typhoons during the project timeline, EVERDRY’s team maintained progress through strategic planning and efficient resource allocation.

Environmental ConsiderationsGiven the hospital’s operational sensitivity, EVERDRY implemented key measures to ensure minimal disruption:

• Noise Reduction: Low-noise equipment was used, and work was scheduled during off-peak hours to minimize disturbances.

• Safety Protocols: Strict adherence to safety measures ensured the well-being of patients, staff, and workers.

Outcome

The project was delivered on time, within budget, and exceeded expectations. Key results included:

• Eliminated Leaks: The newly installed TPO membrane provided robust and reliable waterproofing with an eight-year warranty, ensuring peace of mind for hospital management.

• Minimal Disruption: Hospital operations continued seamlessly due to noise-reduction strategies and careful planning.

• Weather-Resilient Execution: EVERDRY’s proactive approach overcame challenges posed by multiple typhoons.
