The John Glenn Research Center in Cleveland, Ohio is one of NASA’s well known operating locations. As the U.S. government’s space and aviation agency, NASA does not like leaking roofs. Especially when they are protecting critical research equipment, labs, and materials.

One of the laboratory roofs at this base was torn-off, due to complete saturation of the existing insulation, and replaced with our TRITOflex roofing system. An independent, respected roof consulting firm recommended NASA go with a liquid-applied, instant-setting membrane rather than a traditional rolled or sheet good because of the high number of penetrations and flashing requirements on this roof. A factory-manufactured membrane would not only mean a higher cost, but one more prone to leaks and maintenance with reliance on termination bars, bands, caulk, etc.

Quality Installation

The seamless, monolithic TRITOflex membrane was spray-applied to an 80 mil (2 mm) dry thickness, in one coat over the self-adhering bitumen base sheet, with a 20 mil (0.5 mm) TRITOtherm ceramic top coat. The new roof, which is warrantied to withstand extreme winds and hail for 20 years, was installed by a Certified Triton Applicator.NASA has joined the long list of clients who are happy and satisfied with a new leak-free, low-maintenance Triton roof system. After seeing how our roofs compare to roofs on all their other buildings, the TRITOflex system has become a common sense, eco-smart alternative for additional buildings at the center. For use on a different project, NASA actually tested our TRITOflex material in one of their labs. They exposed the membrane to temperatures in excess of 300 degrees F (148 C) and it passed all of their tests with flying colors!

FAA Metal Roof Restored

The existing standing seam metal roof at the Federal Aviation Administration’s Aeronautical Center in Oklahoma City was leaking and repeated attempts to fix the leaks had failed. 

Years of chasing leaks would finally come to an end when the FAA’s architect recommended this building at the Mike Monroney Aeronautical Center in Oklahoma be restored with the TRITOflex fluid-applied roof system. Based on other successful projects completed on numerous FAA facilities with TRITOflex in Oklahoma and Alaska, it was an easy decision.

Weighing the Options

Tearing off the entire roof and replacing it would not only be expensive, but very disruptive . Recovering the metal with a mechanically-attached single-ply membrane was an option, but drilling thousands of fasteners into the old metal deck concerned the FAA’s engineers. Converting a standing seam roof into a metal roof also changes the weight distribution when heavy rains occur, adding to structural concerns.

Another fluid-applied system could have been selected at a cheaper cost, but drastically differing performance. Acrylic coatings are permeable and will continue to allow oxidation and rusting of the metal. They also will not withstanding ponding water and have very poor tensile strength, requiring the use of fabric reinforcement. A silicone coating was also considered because they withstand ponding water. However, silicones have very poor resistance to hail and are prone to splits and zippering tears. Freeze-thaw cycles tend to damage silicones and they can only be repaired with silicone products, as nothing will ever adhere to silicone once it is applied.

So the architect made the smart choice of specifying a spray application of TRITOflex seamless rubber directly over top of the existing metal at 80 mils dry (2 mm), creating a monolithic waterproofing membrane over the entire roof. TRITOflex is water-based, contains no VOC’s, and is easily repaired if damaged. With extremely high elongation and high tensile strength without reinforcement it outperforms all other liquid roofing markets on the market. It will withstand ponding water indefinitely as an impermeable membrane and the only preparation needed was a simple pressure wash.

Cost-Saving & Non-Disruptive

The FAA’s new roof investment was installed quickly and without disruption. They received a 20-year material and labor warranty, backed by 35 years of roofing experience and 50 years of expertise in rubber chemistry. The Certified Triton Applicator completed the system with the TRITOtherm ceramic top coat for additional energy efficiency, even when the roof becomes dirty over time.

The F.A.A. made the right decision to invest in a watertight, flexible, and durable monolithic membrane that will withstand hail, extreme winds, freeze-thaw cycles, and expansion/contraction of the old metal roof.

he 18 year old BUR roof system with ongoing leaks for several years is restored to watertight condition in a matter of days with a new TRITOflex waterproofing membrane system.

The Navy did not want to tear-off the built-up roof and open the building up to the elements. Additionally, there were sections of this building that were added on to at some point and the deteriorating expansion joints between the sections were an issue that required attention.

Limited Options

To avoid a tear-off, the architect recommended a recovery of the existing roof system with 80 mils of liquid rubber waterproofing membrane system. TRITOflex is a water-based, environmentally safe coating system with no VOC’s. Also recommended was a 20 mil white acrylic top coat to be applied over the TRITOflex waterproofing membrane to create a reflective barrier to the sun and reduce heat absorption into the building. This recommendation addressed the building’s ongoing leaks and facilitated an aesthetically pleasing, monolithic waterproofing barrier over the existing deteriorated roof system and wall flashings. Due to the 1900% elongation properties of the TRITOflex membrane, the expansion joints were simply recovered with the liquid rubber coating also.

LQuality, Non-Disruptive Installation

The new roof recovery system was installed in 4 days without disturbing the occupants and will provide the Navy with a 20 year warrantied watertight roof that also reduces their cooling costs in hot California temperatures.

The Nijmegen-Lent Railway Station in the Netherlands needed the highest quality waterproofing solution for their expansion project.

The newly constructed Nijmegen-Lent railway station needed a quality below-grade waterproofing solution for its concrete foundation. The General Contractor, Strukton, went looking for this solution and came into contact with Triton Europe. With decades of experience in below-grade waterproofing, Triton was able to lay out the options.

Limited Options

Triton recommended a TRITOflex liquid rubber waterproofing system to be installed over the concrete foundation due to its high 1900% elongation, extreme adherence to structural concrete, and the ability to spray apply the membrane to the desired thickness in just one coat. TRITOflex is also a water-based, no VOC green product and solution. TRITOflex will be able to withstand structural movements and changes over the years due to its high flexibility. Not only will it and protect the critical components that lay within the foundation of a rail station by keeping water out, but it will preserve this new concrete structure for decades to come.

Quality Installation

The new below-grade waterproofing protection was completed within a few days. The client achieved a warrantied waterproofing system and can rest assured their railway station’s foundation will remain watertight for decades to come during even the worst rainfalls.

Remote Island Air Station Re-Roofed

PROJECT
Eareckson Air Station Re-Roof

LOCATION
Shemya Island, Alaska

SYSTEM

80 mil (2 mm) TRITOflex Membrane

PROJECT SIZE

23,750 square feet

 

The weather on Shemya Island can change in an instant. With limited options available for flat roof replacement, the instant-set TRITOflex material was a natural fit.

Shemya Island, one of the farthest inhabited islands on the west end of the Aleutian archipelago, is host to the Eareckson Air Station. Building #3045’s EPDM roof system had partially blown-off in a storm and was in desperate need of a re-roof. United Roofing Group was called in to provide analysis and recommendations.

Limited Options

With volatile, constantly changing weather patterns in this region of the world, material selection and the logistics of installation were critical decisions. The contractor knew they would need to be creative and think outside of the box. Some sections of the old roof system would have to be torn out and replaced, but most could be left undisturbed to avoid opening up the building to this volatile environment. United Roofing recommended the existing EPDM membrane be covered with a mechanically attached layer of plywood and then immediately sprayed with the instant-set, seamless TRITOflex membrane. With the ability to withstand unforeseen precipitation, TRITOflex creates an instantly watertight membrane. During the summer, temperatures will only reach highs of 60 F. In the winter, snow falls almost daily as precipitation probabilities are nearly 90% half of the year. Therefore, it made sense to select a product like TRITOflex with great cold-temperature flexibility, UV resistance, impermeability, and the highest wind uplift ratings in the industry.

Smooth, Eco-Friendly Installation

Areas of saturated insulation were torn out, replaced, and repaired. A layer of plywood was mechanically attached over the existing EPDM roof system. As the cover board was installed, certified spray technicians used two spray rigs and installed the water-based, VOC-free TRITOflex rubber membrane in one coat to 80 mils (2 mm) dry. The TRITOtrowel brush-applied liquid rubber is then used around drains, scuppers, and flashings for extra reinforcement.

The Air Station received a new, watertight roof to withstand the harshest Shemya Island weather patterns and is backed by a 20-year warranty that covers wind up to 130 mph. Another roof completed with quality products installed by quality people.

Air Force Base’s Metal Roof Restored

PROJECT
avis-Monthan Air Force Base Metal Roof

LOCATION
Tucson, Arizona

SYSTEM
80 Mil TRITOflex Membrane, 20 mil TRITOtherm ceramic top coat

PROJECT SIZE
11,000 square feet

 

The existing metal roof system at the Davis-Monthan Air Force Base in Tucson had previously been coated with other popular roof coatings and required constant maintenance.

This metal roof on the base was previously coated with a reflective acrylic system in some areas and a sprayed polyurethane foam system in others. The acrylic coating required constant maintenance to prevent the spray foam underneath from turning into a sponge. Acrylic coatings are permeable and allow moisture to pass through, which can lead to eventual rusting of the metal it’s supposed to protect. Other problems had been caused by continual movement of the metal, which is to be expected.

Making a Smart Choice

Rather than continue to chase leaks and spend money on constant maintenance, the U.S. Air Force’s team of engineers and designers considered their options. Tearing off the entire roof and replacing it would not only be expensive, but very disruptive to base operations. Recovering the metal with a mechanically-attached single-ply membrane was an option, but drilling thousands of fasteners into the metal was a concern. Not only does this create the possibility for moisture migration, but those fasteners reduce the energy efficiency of the roof by creating a thermal bridge.

The other option was to install a spray application of TRITOflex seamless rubber directly over top of the existing coating and metal at 80 mils, creating a monolithic waterproofing membrane over the entire roof. TRITOflex is a water-based, zero VOC, and is part of an environmentally-friendly system. With extremely high elongation of 1,900%, the ability to withstand ponding water indefinitely as an impermeable membrane, and excellent durability, the only preparation needed was a simple pressure wash. Additionally, the TRITOflex system will hold up to the environment of an Air Force Base located in the desert, including jet fuel exhaust, dust storms, extreme heat, and an occasional hail storm.

Cost-Saving Installation

The Air Force Base chose the Triton solution and not only saved money compared with their other options, but preserved the high R-value obtained by installing polyurethane foam in the first place and avoided wasting that investment. The Certified Triton Applicator completed the system with the TRITOtherm ceramic top coat for additional energy efficiency and protection in the desert sun, even when the roof becomes dirty over time.
The U.S. Air Force made the right decision to invest in a watertight, flexible, and durable monolithic membrane that will withstand movements of the metal underneath and is guaranteed with a 15-year material and labor warranty, with extensions up to 35 years.
