Long-lasting Waterproofing Solution for Complex Roof and Wall Details for a Private Home in Bangkok
A private residence on Rama IV in Bangkok required a reliable waterproofing solution after the homeowner experienced persistent leaks throughout the house.
The client first met the Triflex team at Architect Expo in Bangkok and was looking for a complete, long-lasting waterproofing solution that could finally address the recurring leakage issues. Previous waterproofing attempts had not been able to solve the problem due to the complex roof and wall design, which included numerous seams, joints and window interfaces.
For this type of residential project, the challenge was not only stopping water from entering. It was identifying and sealing the exact weak points where movement, rain exposure and complex detailing had allowed leaks to continue.
The Challenge
The property had a complex roof and wall structure with many critical details, including roof joints, window joints, seams and transition areas.
Conventional waterproofing systems and sealants had been used in the past, but they were unable to provide a complete and durable solution. With so many interfaces across the building envelope, water continued to find weak points and enter the home.
The homeowner needed a waterproofing system that could:
Seal complex roof and window joints
Adapt to irregular details and transitions
Bond securely to the existing surfaces
Accommodate movement over time
Prevent repeated repair cycles
Provide long-term protection for the home
A standard surface treatment was not enough. The project required a detail-focused waterproofing system designed for complex joints and interfaces.
The Solution
Triflex’s experienced application partners proposed Triflex ProDetail as the most suitable solution for the project.
Triflex ProDetail is a liquid-applied, fleece-reinforced waterproofing system developed for difficult details, joints, upstands, transitions and interfaces. Because it is applied in liquid form, it can adapt to complex shapes and create a seamless waterproofing layer around areas that are difficult to protect with conventional systems.
For the Rama IV private house, the system was applied to seal the critical roof and window joints, creating a fully bonded waterproofing layer across the vulnerable areas.
This approach helped provide a durable, effective and cost-efficient solution for the homeowner, reducing the need for repeated repairs and improving long-term protection against water ingress.
System Overview
Totally cold applied, with no risks from hot works
Suitable for all common roof details and repairs
Compatible with virtually all roof substrates
Exceptionally rapid curing / rainproof times, even at low temperatures
Fully reinforced waterproofing technology
Designed to allow use on vertical surfaces
Simple, single process waterproofing application
Seamless - with no joints, seams or fixings
Results
After application, the roof and window joints were seamlessly sealed using Triflex ProDetail.
The solution provided the homeowner with a durable waterproofing system designed to prevent water ingress at the most vulnerable areas of the house. By treating the joints, seams and interfaces directly, the project addressed the root cause of the leakage rather than applying another temporary surface repair.
The result was a long-lasting waterproofing solution for a complex residential structure where conventional systems had previously failed.
