MTI Core Cavity Weep

CORE CAVITY WEEP™

WEEPS FOR CMU VENEERS

CCV 5020

DRAIN BLOCK CORES & VENEER CAVITY

CMU and Jumbo Brick Veneers create two cavities where water can accumulate: in the block cores and the cavity between the veneer and the structural back-up wall. Core Cavity Weep™ features a unique design that drains both the cores and the wall cavity by creating drainage tunnels below the bed joint mortar directly on the flashing.

APPLICATIONS

• CMU veneers: Designed specifically for concrete masonry units and jumbo brick veneers.

THE MTI ADVANTAGE

• Forms bottom of bed joint mortar: Ensures proper drainage and stability.
• Weeps at the lowest point of the wall: Effectively channels moisture out of the structure.
• Drains cavity and block cores in CMU or jumbo brick veneer: Dual drainage capability for comprehensive moisture management.
• Easy-to-install self-spaced weeps: Simplifies the installation process.

CORE CAVITY WEEP™ INSTALLATION

1. Position Core Cavity Weep™ on the flashing with the material centered on the wall. Ensure intermittent legs extend into the wall cavity and to the exterior.
2. Place a bed joint of mortar on Core Cavity Weep™ and lay masonry units following standard installation procedures.
3. Tool joints and lightly score the legs at the face of the wall. Crack off the legs by pushing downward while the mortar is still plastic.
4. Finish tool joint and brush the surface for a clean, professional appearance.
