1. What is liquid-applied waterproofing (exposed type) for commercial buildings?
It is a seamless, flexible waterproofing system applied in liquid form that cures into a durable membrane. Designed to remain fully exposed, it protects commercial structures from rain, UV exposure, and thermal movement without requiring tiles or screed protection.

2. Which commercial areas are suitable for exposed liquid waterproofing?
This system is commonly used on:
Roof decks and podium decks
Office and mall balconies
Exterior walls and façades
Parapet walls and gutters
Canopies and service decks
It is ideal for office buildings, warehouses, retail centers, mixed-use developments, and apartment buildings.-exposed type waterproofing
3. Is exposed liquid waterproofing suitable for high-rise commercial buildings?
Yes. When installed by trained professionals using proper safety systems, exposed liquid waterproofing performs well on mid-rise and high-rise commercial structures, including vertical façades.
4. How does exposed liquid waterproofing perform in Philippine weather?
It is formulated to resist heavy rainfall, strong UV rays, high humidity, and temperature fluctuations, making it suitable for long-term use in the Philippine climate.
5. How long does exposed liquid waterproofing last on commercial properties?
With proper surface preparation and professional installation, it can last 5 years or longer, depending on exposure, building movement, and maintenance practices.
6. Can this system handle structural movement in commercial buildings?
Yes. The elastic membrane accommodates thermal expansion and minor structural movement, helping prevent crack propagation and water ingress.
7. Is liquid-applied waterproofing better than sheet membranes for commercial use?
For many commercial applications, yes. Liquid-applied systems offer:
Seamless coverage with no overlaps
Better performance on complex details
Easier future repairs without full removal
8. Can the waterproofed surface support foot traffic?
Some systems allow light maintenance foot traffic. Areas with frequent or heavy traffic may require additional protective coatings or specialized systems.
9. How long does installation take for commercial buildings?
Project duration depends on surface area, weather, and site conditions. Most commercial applications require several days, including curing time before full exposure.
10. What maintenance is required after installation?
Routine inspections, cleaning of drains and gutters, and timely minor repairs help maintain waterproofing performance and extend service life.
11. Why is professional installation critical for commercial buildings?
Commercial projects demand:
Proper substrate assessment
Correct application thickness
Compliance with safety and quality standards
Professional installation minimizes failure risk and protects long-term asset value.
12. When should commercial building owners consider re-waterproofing?
Re-application should be considered when signs such as aging membranes, recurring leaks, or surface deteriorationappear. A professional inspection is recommended.
