Case Study: Resolving Recurring Roof deck Leaks Through TPO Waterproofing | TPO Waterproofing Philippines

Client Profile: Commercial Building

Location: Metro Manila

Waterproofing History: Multiple systems installed by different contractors

Background

The client experienced persistent roof leakage issues over several years. Prior to engaging Everdry Waterproofing, four different waterproofing systems had been applied, including liquid-applied coatings and multiple torch-applied membranes by various contractors. While these systems initially addressed leakage, their performance was limited, with an average service life of approximately five years.

This resulted in repeated waterproofing works, increased maintenance expenses, and ongoing operational disruptions, prompting the client to seek a more durable and long-term solution.

Challenge

To identify and implement a high-performance waterproofing system that could withstand prolonged exposure to harsh weather conditions, minimize future maintenance requirements, and provide extended warranty coverage suitable for a commercial property.

Solution: TPO Waterproofing System by Everdry

Following a comprehensive site inspection and technical evaluation, Everdry Waterproofing, a TPO system specialist, recommended the installation of a TPO (Thermoplastic Polyolefin) membrane waterproofing system designed for long-term performance and reliability.

Technical Specifications (Typical):

• Membrane Type: Thermoplastic Polyolefin (TPO)

• Membrane Thickness: 1.2 mm – 1.5 mm (subject to design requirement)

• Installation Method: Fully adhered / mechanically fastened (as applicable)

• Seam Treatment: Hot-air heat-welded seams forming a continuous waterproof barrier

• UV Resistance: High resistance to ultraviolet radiation and thermal aging

• Chemical Resistance: Resistant to algae, mold, and common atmospheric contaminants

• Puncture Resistance: Enhanced resistance to impact and foot traffic

• Thermal Performance: High reflectivity to reduce heat absorption and roof surface temperature

• Service Life Expectancy: 20–25 years with proper installation and maintenance

• Warranty Coverage: Extended manufacturer and workmanship warranty (subject to system design)

Result

The TPO membrane system provided a monolithic, durable waterproofing solution that significantly reduced the risk of leaks and eliminated the need for frequent repairs. The system’s smooth surface allows for easier inspection and preventive maintenance, supporting long-term roof performance.

The client benefited from improved waterproofing reliability, lower lifecycle maintenance costs, and extended warranty coverage, enhancing the overall value and protection of the commercial asset. | TPO Waterproofing Philippines

Conclusion

By transitioning from short-term waterproofing solutions to a technically robust TPO membrane system, the client achieved a sustainable and long-term waterproofing strategy. With Everdry Waterproofing’s technical expertise, the building now benefits from enhanced durability, reduced maintenance intervention, and improved asset protection.
