Henry^® Prodeq™ System: Waterproofing That Keeps Projects Moving

Today’s construction jobs are under pressure from tight schedules, complex designs, and harsh weather. Horizontal surfaces like split slabs, balconies, planters, and podium decks need fast, effective waterproofing that can handle those challenges without holding up other trades.

Henry^® Prodeq™ is a spray-applied, instant-setting waterproofing membrane that forms a seamless barrier in seconds. It helps installers stay ahead of schedule, avoid delays, and reduce risk in high-traffic, exposed applications.

Fast Application, Fewer Delays

Crews using Prodeq can prep, prime, and spray in the same shift—no need for heat, protection boards, or extended cure time. Because it sets instantly, Prodeq can be walked on the same day, allowing work to continue without interruption.

Tyler Brown, Vice President of Baltimore Waterproofing, has used Prodeq on multiple projects. “The number one challenge on all projects is UV exposure,” said Brown. “With Prodeq, we can get on a deck, spray it in a day and not worry about UV exposure and possible damage.”

He added, “We can waterproof an 8,000 square foot area in one day with a 3-4 man crew. With hot-applied, you need double the manpower to get the same coverage.”

Simple Detailing, Reliable Results

Because Prodeq goes on as a liquid and cures as a single membrane, it doesn’t require laps, welds, or termination bars. That makes it easier to detail around drains, corners, and vertical transitions. The fully adhered system sticks to green or damp concrete and holds up to traffic, root intrusion, thermal movement, and water immersion.

Prodeq has been used on courtyards, balconies, terraces, and roofs in jobs where other methods would have caused project delays or required more labor. The membrane resists damage from UV and can stay exposed for extended periods before the overburden is installed.

Project Spotlight: Convergence in Oklahoma City

One example of how Prodeq performs under real-world conditions is the Convergence development, a mixed-use project designed to support innovation and collaboration in Oklahoma City. This project shows how the right waterproofing choice can help keep a complex, high-profile job on track—even when deadlines are tight and weather or trade coordination becomes a challenge.

The project involved waterproofing a 33,000-square-foot plaza deck using the Henry® Prodeq™ System. Architect Joshua Mullins of FSB Architects & Engineers selected Prodeq to address detailing challenges, speed up return to service, and keep staging simple.

Despite delays from other trades, the Prodeq system helped the crew from Alpha Insulation and Waterproofing stay on schedule. The membrane’s fast cure and durability made it the right choice for a high-profile project facing tight deadlines and changing conditions.

Support and Training

Brown said the Henry team provided the support his crew needed to start using Prodeq with confidence. “We’ve worked with Henry products for 30 years,” he said. “They helped train our team, and we even invested in our own spray equipment. Prodeq makes it easier to manage multiple jobs at once. It’s just more efficient.”
