With CMU Backing and CMU Foundation
This detail illustrates a base of wall condition with a partially grouted and reinforced concrete masonry foundation. Below grade waterproofing and an air/moisture/vapor barrier above grade provide continuous resistance to air and moisture; continuous insulation offers excellent thermal control. The flexible thru-wall flashing is supported across the cavity with rigid insulation and grout. An optional cavity drainage insert protects the weep vents from becoming obstructed. The detail incorporates a vertical brick expansion joint and a vertical control joint at the block backing. Finish grade is held away from the wall with a gravel mowing strip, protecting the masonry against moisture. A system of flashing and weeps at the base allow moisture to exit the drainage cavity. The durable drip edge guards against moisture reentry and may be notched to avoid excessively thick laps.
