City Hall’s Green Roof Retrofit

PROJECT
City Hall Green Roof

LOCATION
De Pere, WI

SYSTEM
80 (2 mm) TRITOflex Membrane

PROJECT SIZE
8,000 sq. ft

 

The City of De Pere, Wisconsin decided to convert their worn-out EPDM roof into an environmentally-beneficial roof-top garden.
The old, worn-out mechanically-attached EPDM roof was in constant need of repair and ready for replacement. The City of De Pere were intrigued by the long-term benefits of a green roof, after speaking with Hanging Gardens, a Milwaukee-based green roof design firm. A structural analysis confirmed the roof deck and structure could hold the weight of a green roof.

Looking at all Options

Rather than go the traditional route and tear off the old roof, install new expensive insulation, and then a new membrane, Hanging Gardens informed them of the TRITOflex restoration option. It made perfect sense. The City could use their existing EPDM roof to their advantage, rather than waste it, by adding 80 mils (2 mm) of highly flexible, durable, and ponding water resistant TRITOflex rubber. As a seamless, self-terminating liquid membrane, this would eliminate traditional failure points of seams, overlaps, and flashings. Any other liquid-applied membrane would have not be acceptable to install a green roof over.

Quality Installation

After a good pressure wash, TRITOflex was spray-applied by Zander Solutions, a Certified Triton Applicator, to 90 mils (2.2 mm) dry in one coat over the existing 9,000 sq. ft. EPDM roof. EPDM rubber is naturally a long-lasting, strong material. With the addition of TRITOflex on top, not only did it save the city money, but provides them a “bullet-proof” roof for decades. TRITOflex is impermeable and will withstand ponding water indefinitely, making it the ideal solution to keep a building watertight with a green roof over top.

The total system included the ILD electronic vector mapping leak detection system, drainage mat, filter fleece, growing medium, and sedum mats. There is also a video taken by the local new station showing some of the green roof here: http://fox11online.com/news/local/green-bay/de-pere-city-hall-installs-green-roof.

Benefits of a green roof versus a traditional roof:

  • Reduces stormwater runoff and improves water quality
  • Reduces energy consumption
  • Promotes biodiversity
  • Helps reduce air pollution and improves air quality
  • Increases overall roof life

Eco-House Waterproofing

PROJECT
New Eco-House – Building Envelope Waterproofing

LOCATION
Heerlen, Netherlands

SYSTEM
80 Mil (2 mm) TRITOflex Membrane

PROJECT SIZE
Triton Europe

 

When an Eco-Building Contractor heard about TRITOflex, he knew it was the best choice for many building envelope areas of this Eco-House in Holland.

The Eco-Building contractor and the architect for this new Eco-House being planned for construction in Heerlen required the use of only green, environmentally friendly products throughout the building envelope. From the concrete foundation and slab to the roof, high quality waterproofing with only green products was desired.

Green Alternative Chosen

Triton Europe recommended a TRITOflex liquid rubber waterproofing system to be installed throughout the building. TRITOflex is a green product: water-based, no VOC’s, and environmentally friendly. It is an extremely flexible and durable waterproofing system that can be used for the entire building, from the foundation to the roof. With its ability to adhere to virtually any substrate, TRITOflex could be used in many areas with this new project and would protect this important investment from the elements.

Exciting Installation

The architect and contractor were excited about choosing TRITOflex for this project. First, the foundation and concrete floor joints were sprayed with 80 mils (2 mm) of TRITOflex instant-setting liquid rubber membrane. After that, they sprayed TRITOflex to flash the foundation to the supporting walls in order to protect against any rising water. A week later, they finished the construction of the house and then sprayed a 80 mil (2 mm) TRITOflex membrane directly over the plywood roof deck since the insulation was installed from underneath the deck.


This house is now watertight from top to bottom and will be well protected by the durable and strong, yet flexible, TRITOflex system.

Historic Water Fountain Restored

Alan Stevens Associates

 

Leaking historic water fountain is restored above an underground parking garage.

As part of a large plaza deck renovation for a financial institution’s office in Pasadena, California, the consultants and general contractor encountered a difficult task. The historic water fountain in the middle of the plaza deck on top of the underground parking garage had been leaking for years. This fountain had been designed by a famous local architect decades ago and preserving its original appearance was of utmost importance. Additionally, the consultants knew most of the fountain’s original waterproofing and decorative tile would need to be removed as they had been saturated for too long and were coming loose.

Limited Options

TRITOflex installed on walls before coating

The contractor was instructed to remove all of the fountain materials down to the original concrete and start over with new. The concrete was allowed to dry and then repaired. Next was determining which waterproofing membrane to use considering the difficult application and need to install tile directly on top. When all options were discussed by the team and many waterproofing manufacturers declined to guarantee their system for this application, the TRITOflex membrane was chosen. With 1,900% elongation, the ability to install at 80 mils dry in one coat, and high compatibility with thin-set mortar and tile, TRITOflex rose to the top.

Quality Installation

TRITOflex was spray applied at 80 mils (2 mm) dry in one coat and the tile was adhered directly on top with thin-set mortar. The warrantied TRITOflex membrane is able to withstand water indefinitely, making it an ideal choice for projects like water features, fountains, ponds, and planters.

The client achieved a durable, flexible, and green rubber waterproofing membrane that will hold the decorative tile and keep this beautiful, historic water fountain from leaking below.

Basement Foundation Waterproofing

PROJECT
Residential Below-Grade Waterproofing

LOCATION
Tawa, New Zealand

SYSTEM
2 mm TRITOflex Liquid Rubber

PROJECT SIZE
100 square meters

 

The owners of this house in Tawa, New Zealand had just about given up trying to get their basement water intrusion problems sorted out.

The basement of this house had been leaking for a longtime and the problems had become almost too much to handle. The owners had multiple waterproofing contractors come in and try to solve the problems, to no avail. On rainy nights, the owner said they would have to get up three to four times during the middle of the night to clean the water up with a wet-dry vacuum. They were in desperate need of a solution that works.

Limited Options

The contractor discussed potential causes of their waterproofing problems with the homeowners. Previous waterproofing had mostly attempted to solve the issues from the inside of the basement with negative-side waterproofing practices. However, negative-side waterproofing is always difficult when a large amount of hydrostatic pressure from outside of the foundation exists. The contractor explained that a positive-side waterproofing system was their best, and really only, option. This meant that the ground around their basement must be excavated and removed in order to properly install a positive-side waterproofing system on the outside of the foundation walls. The contractor recommended the TRITOflex liquid rubber membrane as the waterproofing solution. Due to its 1900% elongation, extreme resistance to high amounts of hydrostatic water pressure, strong adherence to concrete, and high puncture resistance and durability, the homeowners wanted the best of the best product to fix their problems for the long-term.

Quality Installation

The TRITOflex liquid rubber waterproofing was quickly installed in just one coat to the basement foundation walls after the excavating, pressure washing, and priming. A drainage mat and protection course was then installed before backfilling. The exposed areas of waterproofing were coated white to match the existing color. The contractor also used TRITOflex to waterproof the concrete ramp walkway leading to the house that also was a source of water entry. Since TRITOflex is resistant to heavy foot traffic, it worked as a great waterproofing solution for this area.

After TRITOflex was installed, it rained heavily for a solid week. The contractor went back after that week to follow-up and the owners smiled brightly and showed him there wasn’t a single leak.

Air Barrier in Downtown Skyscraper

PROJECT
Skyscraper Air Barrier Solution

LOCATION
Des Moines, IA

SYSTEM
40 Mil TRITOflex Air/Vapor Barrier

PROJECT SIZE
2,000 square feet

 

Air stack problems in a 45 story building coming from the top sent the managers looking for a top notch air barrier solution.

The elevator control room above the elevator shafts at the top of this 45 story tall skyscraper in downtown Des Moines had large amounts of air infiltration through the walls, resulting in air stack effect that caused issues regulating the internal temperatures and air flow within the building. In order to reduce operating costs, an air barrier needed to be installed on the interior walls of the elevator control room in the top of the skyscraper.

Limited Options

The client needed an air barrier that would be durable, thick, and withstand any air or even vapor infiltration. It also needed to be fire resistant and environmentally safe. After finding out how quickly the TRITOflex membrane could be installed to these bare walls, that it has no VOC’s, and that it would result in a great looking finish, the client chose TRITOflex to keep the air from entering in and save them money on their monthly bills. The non-disruptive aspect of the installation, especially having virtually no odor, was also critical.

Quality Installation

TRITOflex was spray applied at 40 mils (1 mm) dry in just a few hours to all of the walls and the transition from the wall to the floor to seal the room from air infiltration. All small and hard to reach areas were sealed with roller and brush applications of TRITOtrowel. Then the air barrier was coated with a white paint to give the client their desired color.

The client achieved a durable, sustainable, and green rubber air barrier that immediately solved their air stack effect problem and will also prevent any moisture or vapor from entering the control room.
