Drainage mat systems are essential for protecting building exteriors in Rhode Island, where coastal humidity and seasonal precipitation create ideal conditions for moisture intrusion. Whether you’re working on a historic home in Newport or a new construction in Providence, drainage mats provide a protective layer behind stucco, stone veneer, or siding to ensure long-term durability.
Why Rhode Island Buildings Need Drainage Mats
Rhode Island experiences around 47 inches of rainfall annually, with additional moisture coming from coastal air, snow, and fog. These conditions can trap water behind cladding materials, leading to:
-
Mold and mildew growth
-
Rotting of sheathing and framing
-
Blistering or peeling of exterior finishes
-
Reduced energy efficiency
Drainage mat systems help mitigate these issues by creating a ventilated cavity behind the cladding, guiding moisture down and out of the wall system.
What Is a Drainage Mat System?
A drainage mat is a breathable, corrugated or mesh material that installs between the weather-resistant barrier (WRB) and the exterior cladding. It:
-
Channels water away from the sheathing
-
Allows air circulation for drying
-
Works in tandem with flashing and sealants
-
Prevents moisture entrapment and hydrostatic pressure buildup
These systems are used across a variety of cladding assemblies, including EIFS, stucco, fiber cement, stone, and wood siding.

Drainage mats are also widely recommended during re-siding projects or when installing stone veneer.
Installation Process
Installation typically involves:
-
Applying the WRB to the sheathing
-
Placing the drainage mat over the WRB
-
Fastening it with approved mechanical fasteners
-
Installing the cladding system over the mat
-
Sealing all windows, doors, and penetrations with proper flashing
Given Rhode Island’s climate, ensuring proper flashing and drainage detailing is critical for long-term success.
Pricing in Rhode Island
Costs for drainage mat systems in RI vary based on:
-
Mat thickness and material
