Stoneyard.com recommends a moisture control cavity weep system to protect your stone veneer

Why include a weep system?

Veneer stone is not a structural wall, it is either adhered to the structural wall (thin veneer) or anchored to a weight bearing foundation (building veneer). Stone and mortar are porous and so water can eventually weep through these materials and cause two potential issues: damage to the substrate or efflorescence (salt from the water).

What does a weep system offer?

Cavity weep systems are designed to protect against these two problems. It consists of vertical channels and corrugated exit holes that allow moisture that does penetrate to safely exit down the wall and out through the face. There are also accessories for corners and special situations like windows and finished grade changes.

What is recommended?

Our recommended weep system is from MTI (Masonry Technology Incorporated). Their website is www.MTIdry.com. Below you will find several diagrams that illustrate wall cross sections for both adhered (thin) veneer and anchored (building) veneer.
