The AMICO Hydrodry® Moisture Control System
HYDRODRY® is a proprietary self-draining, vented wall moisture control system that works by creating a defined drainage and ventilation cavity behind veneer stone, stucco, fiber cement and various other exterior claddings.
HYDRODRY® allows your exterior walls to drain and breathe to help protect the structure and air quality of your home – A dry home is a healthy home.

HYDRODRY® WORKS WITH
FIBER CEMENT, STUCCO,
The HYDRODRY® Moisture Control System is a self-draining vented wall system that attaches behind a veneer stone wall, stucco, or masonry siding. It works by creating a defined ventilation cavity within the wall to eliminate trapped water.
The unique patented high-performance profiles, which are stacked in a series, help water to drain from the walls. The remaining water evaporates through the vent system located at the top of the wall.
The layers begin with an AMICO-approved weather resistance barrier — in compliance with the local building rules. On top of it, an AMICO rain screen is installed to create air and water drainage cavity. Its compressive strength maintains the airflow cavity throughout the wall. A matrix design follows, which ensures a gravity-induced water flow, achieving a 99.2% drainage rate and moisture control. The layers are multi-directional, allowing for an installation in all directions, and have a fire retardant composition that provides class A flame spread that meets and exceeds building standards.
A drain screed induces the drainage of water through a built-in trough, which allows for moisture to flow freely down the HYDRODRY® rain screen and drains out the water through a series of drainage slots within the system. The dual drip edges divert water away from the wall, and the compressed design allows for a stylishly low-profile look.
Apart from stylistic reasons, the profile is critical when installing a rain screen because it will not allow the bottom of the stucco wall to flare out and crack — which is highly likely with rain screens installed with traditional weep screeds. Our EZ vent at the top of the wall turns up the temperature to let water evaporate through the venting slots creating moisture control.
Another key HYDRODRY® profile is AMIFLOW. It is a versatile profile that allows you to fully vent a wall over doorways, mid walls, and window’s sill stones. The heavy-duty construction makes it perfect for venting veneer stone walls or other types of cladding.
HYDRODRY® allows for trapped water in the walls to be released, letting the structure breathe and the exterior wall cavity to remain dry or quickly dry off. While traditional systems with rain screens in buildings remove the trapped water in walls, they also trap the walls’ moisture with no escape. Our HYDRODRY® system works to remove water both through drainage and evaporation.
You can install the system in doorways, windows, sill stones, roof pitches, and other detailing to accommodate the trapped water within walls and other cavities.
AMICO HYDRODRY®, a self-draining vented wall moisture control system for use behind masonry wood and shake siding, veneer stone, and stucco was awarded the 2020 “Green Innovation of the Year” by Green Builder Magazine.
The prestigious award was given as part of Green Builder’s “Home of the Year and Sustainability Awards” program – now in its 12th year – which spotlights individuals, projects and products that encourage sustainability and efficiency.
MAKE SURE WATER DRAINS AND VENTS FROM YOUR WALL CAVITY
BEFORE DAMAGE OCCURS!
MOISTURE IN THE WALL CAVITY
A GROWING PROBLEM FOR NEW HOME BUILDERS
In recent years the building industry has seen an increase in moisture problems as it relates to the exterior cladding of newly built homes. These issues are affecting all types cladding including stucco, veneer stone and fiber cement. Our research shows that there are a few main factors that are impacting this sudden increase in moisture intrusion, some of these include the following:
- Recent code changes and products designed to seal the house and improve energy efficiency have caused moisture to accumulate and become trapped between the OSB and exterior cladding
- Upgraded insulation, combined with house wraps fail to allow air to pass through the wall cavity allowing moisture to dry as it has in the past
- Extreme temperature differentials between the inside and outside of the building causes moisture to accumulate in the wall cavity
- Water that is not released and remains inside the wall cavity will eventually permeate the OSB, studs and drywall causing mold, mildew and rotting problems
MOISTURE CONTROL SOLUTION
HYDRODRY® is a unique self draining, vented wall moisture control system that works by creating a defined drainage and ventilation cavity behind stucco, veneer stone and various other exterior claddings. A series of unique profiles allow water to drain from within the wall cavity. The remaining water vapor is then allowed to evaporate and escape through a vent system located at the top of the wall.
Other moisture control solutions on the market can allow water to flow down the wall but they fail to provide an adequate escape from the bottom of the wall. AMICO’s patented profile system allows water to freely drain from the bottom while a top vent allows vapor to escape from the top of the wall.
