In the world of construction, managing water drainage is a critical aspect of ensuring the longevity and durability of structures. One innovative solution that has gained significant attention is MortarNet 2″, a drainage mat designed to address water-related issues in masonry walls. In this blog, we’ll dive into what MortarNet 2″ is, how it works, and why it’s becoming a must-have in modern construction projects.
What is MortarNet 2″?
MortarNet 2″ is a high-performance drainage mat specifically engineered for use in cavity walls and masonry veneer systems. It is designed to facilitate the efficient drainage of water that penetrates the outer masonry layer, preventing moisture buildup that can lead to structural damage, mold growth, and other issues.
The product is made from a durable, non-corrosive polypropylene material, which ensures long-term performance even in harsh environmental conditions. Its unique design features a three-dimensional structure that allows water to flow freely while providing a barrier against mortar droppings that could clog the drainage system.
How Does MortarNet 2″ Work?
MortarNet 2″ is installed horizontally between the masonry veneer and the structural backing (such as a concrete block or steel frame). Here’s how it works:
- Water Drainage: When water penetrates the outer masonry layer, MortarNet 2″ channels it downward and out through weep holes, preventing it from accumulating behind the wall.
- Mortar Droppings Prevention: During construction, excess mortar can fall into the cavity and block drainage paths. MortarNet 2″ acts as a barrier, catching these droppings and ensuring the drainage system remains clear.
- Air Circulation: The design of MortarNet 2″ also promotes air circulation within the wall cavity, which helps to evaporate any residual moisture and maintain a dry environment.
Key Benefits of MortarNet 2″

- Enhanced Durability: By effectively managing water drainage, MortarNet 2″ helps to prevent moisture-related damage such as efflorescence, spalling, and freeze-thaw cycles, extending the life of the structure.
- Improved Energy Efficiency: A dry wall cavity contributes to better thermal performance, reducing energy costs associated with heating and cooling.
- Code Compliance: MortarNet 2″ meets or exceeds building code requirements for drainage in masonry walls, making it a reliable choice for architects and contractors.
- Ease of Installation: The product is lightweight and easy to handle, reducing labor costs and installation time.
- Sustainability: By preventing water damage and improving energy efficiency, MortarNet 2″ contributes to more sustainable building practices.
