HyppoCoat GC System

Single Component Elastomeric Modified Urethane Horizontal & Vertical Waterproofing Membrane

HyppoCoat GC (Green Concrete) is a user-friendly, high solids, single component, liquid applied membrane for cured or green concrete. The system uses two coats of a modified urethane coating and protection board to create an elastomeric system designed to expand and contract with normal structural movements.

Single Component Elastomeric Modified Urethane Waterproofing Membrane

HyppoCoat GC (Green Concrete) is a user-friendly, high solids, bitumen-modified, coal-tar free, single component liquid applied membrane for cured or green concrete. The system uses two coats of a modified urethane coating and protection board to create an elastomeric system designed to expand and contract with normal structural movements.

HyppoCoat GC is easy to use and can be applied immediately after green concrete forms have been removed, providing a very quick return-to-service window during application. It also acts as an aggressive barrier against harsh chemicals, abrasive wear, and heavy impact.

Where It Is Used

HyppoCoat GC is designed for use on foundations, backfilled walls, split slab applications, planters, and submerged conditions.

Applications

  • Green Concrete
  • Balconies
  • Masonry
  • Storage Areas
  • Basements
  • Tunnels
  • Plaza Decks
  • Foundation Walls
  • Restrooms
  • Parking Decks
  • Planters
  • Bridges

Benefits of the HyppoCoat GC System

Single Component System

No mixing and no ratios to measure — HyppoCoat GC is ready to apply straight from the container, which keeps installation simple and removes a common source of application error.

Quick Return to Service

Can be applied immediately after green concrete forms have been removed, opening a very short return-to-service window during application.

100% Solids & Low VOCs

A high-solids, coal-tar free formulation with low VOCs, so it can be specified where solvent-heavy systems are restricted.

Easy, Labor-Saving Application

Two coats of a modified urethane coating go down quickly with no special equipment, reducing labor time and cost.

Cures in 4–6 Hours

Cures in 4–6 hours, or 2–4 hours with water added, depending on the applied mil thickness.

Expands & Contracts

The elastomeric system is designed to move with normal structural movement rather than crack under it.

Aggressive Chemical & Impact Barrier

Stands up to harsh chemicals, abrasive wear, and heavy impact once cured.

Meets ASTM C-836 & E-96

Tested to ASTM C-836 and ASTM E-96, supporting specification on foundations, backfilled walls, split slabs, planters, and submerged conditions.

Installation Videos

The success of a roofing & waterproofing system is ultimately reliant upon the accuracy of the installation. Each demo walks through a Barrett system step by step, straight from the crews who install them.

Project Profiles

The original project scope of the Baltimore Convention Center called for the replacement of the existing roof membrane due to membrane failure and subsequent leaking into the Convention Center’s main halls below. Once the site was studied, the Barrett Company suggested that the Convention Center take advantage of the opportunity to upgrade the aesthetic and functional qualities of the Terrace with a Greenroof installation.

A 92-year-old monument surrounded in priceless marble which took 50 years to build presented a unique challenge – and no room for error – for the company tasked with the first skylight and roof replacement project of the Lincoln Memorial in Washington, D.C., in 1995.

When you think of a big city, often what immediately jumps to mind are skyscrapers, traffic, and your favorite sports team. But many of these big cities are also known to produce a lot of emissions that spread into the atmosphere. One of the biggest culprits of this growing problem—Chicago.

Salesforce Transit Center is a landmark for the San Francisco Bay Area. This striking, innovative, and sustainable multi-story building transforms a transportation hub into an urban experience, complete with a gondola, and topped off by a 5.4-acre rooftop park open to the sky.

In 2011, the D.C. Public Library began plans for the modernization of the Martin Luther King Jr. Memorial Library. The original vision for the Washington, D.C. landmark, designed by modern master Ludwig Mies van der Rohe, used transparency and light as metaphors for freedom and knowledge, the very principles of Dr. King’s life teachings. More than 40 years later, the team at OTJ Architects was selected to helm the transformation of Washington’s Central Public Library.

In 2005, the Federal Deposit Insurance Corporation (FDIC) adopted a new objective— To evaluate & measure the operational energy conservation of its Virginia Square facility and identify opportunities to further conserve energy and reduce utility costs.

Can you imagine the weight of about 125 semi-trucks, but in gold? Approximately, ­­­10 million pounds, or $236.4 billion, of gold is held at the Fort Knox Bullion Depository, also known as the “gold vault,” in Fort Knox, Kentucky. The vault holds more than half of the gold reserves of the United States making the protection of the contents of the vault a top priority for the contractors and architects tasked with reroofing it.

After evaluating the roof of their 240,000 sq/ft facilities building, the management team at LinkBelt Construction Equipment did just that. Thanks to Barrett’s Ram Cold Tar® Plus roof restoration & repair system & Ram Ultra-Silver® reflective aluminum finish, the result was a new, fully detailed, watertight roofing system that saved the company time, money, and energy.
